The Problem in serialization.
The serialization issue is a trivial one at the moment. However the threat of a version change is imminent considering the next release of JDK 6 "Mustang" may have considerable improvements especially on the Swing side. Therefore, I strongly encourage you to write your own code to persist the tree data into a file. Such a logic is much preferable as it will over-come the issues with serialization.
The main problem with a version change is that every serializable class uses a special random number stored in a private static field called serialVersionUID. So when the serializable class is serialized, this number is also persisted to the serialized form.
When the object is de-serialized, the number is also deserialized. Java checks the de-serialized number against the serialVersionUID field of the class and verifies if the two match. If they do, it means that the deserialized data is in the right format of the class. If they differ, a InvalidClassException is thrown. Every new version of the class changes this unique number. Hence an object serialized with an older version of the class will not be allowed to be de-serialized by a new version of that class and vice-versa.
This mechanism allows developers to version their new releases and ensures that serialization and deserialization operations remain consistent across multiple-versions and prevent invalid state of the object.
The serialization issue is a trivial one at the moment. However the threat of a version change is imminent considering the next release of JDK 6 "Mustang" may have considerable improvements especially on the Swing side.Don't make statements like this unless you know what you're talking about. Do you know that Sun's JDK release policies prevent them from doing that in the middle of a release? and that they haven't done such a thing in 13 years? Do you have any actual evidence that they are going to change serialVersionUIDs in the middle of a release?
Therefore, I strongly encourage you to write your own code to persist the tree data into a file.
I would strongly encourage developers not to use Serialization on Swing objects at all, which curiously enough is what the Javadoc has been saying for ten years. You should use java.beans.XMLEncoder for this. That's what it is for.
Such a logic is much preferable as it will over-come the issues with serialization.Home-grown code is never preferable to what is provided in the JDK.
The main problem with a version change is that every serializable class uses a special random number stored in a private static field called serialVersionUID.That's not a 'problem'. That's part of the solution.
Every new version of the class changes this unique number.Only if you don't declare your own static final long serialVersionUID.
This mechanism allows developers to version their new releases and ensures that serialization and deserialization operations remain consistent across multiple-versions and prevent invalid state of the object.Exactly. I suggest you read the Versioning section of the Serialization specification before posting again on this topic, and also read up on Long Term Persistence in Java Beans. You have much of this information back to front, and you don't appear to have heard of either defining your own serialVersionUID or Long Term Persistence.
And your claim that Sun will change serialVersionUIDs in the middle of Java release 6 is just ludicrous.

Problem with Serialization from Threads
I'm quite new to java threads, and i'm doing a simple server.
It opens a thread for every socket connection that is opened, so the Socket is extern to the Thread.
When I try to serialize on the socket a Vector (that contains Vectors, etc..) that is extern to the Thread, the first time everything goes ok, but when the thread modifies some variables in some objects contained in a vector(that, i repeat is extern to the thread), the serialized object doesn't seem to change, and the client continues receiving the same variables, without change.
In a first time i thought that maybe creating a thread, the second one took a copy of the space of addresses of the main one(and so when i modify a variable from a thread the variable in the main thread didn't change), but i read that java uses the same space of addresses for every thread, so i don't really know what it could be.
Maybe i've not been clear so i make an example:
MyType is a class containing some fields, let's put x and y
In the class MainClass i have an istance of this class, and also a socket and from here i open a thread of class MyThread
MyThread modifies x and y in a object of MyType contained in the "3D array" that is in MainClass
Then from that thread i serialized on the socket (which was been passed by MainClass).
Well, doing this way the vector that the client receives has always the x and y fields unchanged.
Please help me, cause i've been thinking all day of what it could be and found nothing on the web.
Also sorry for my poor english.I thought that could be the problem, but it wasn't.
The client still receives the vector with objects
unchanged.
I think the problem is that the thread can only access
to a copy of the class that contains the vector, and
so when i send the real one, it isn't changed.not likely. one of the things about threads is that they share everything but local (read: non-Object) data. All objects are accessible to any thread of your application, as long as that thread has a reference to it. -
A problem using serialization and/or not overwritten variables
I have a problem while writing objects in ObjectOutputStream :
Here is a simplified version of the program :
class InDData implements serializable
private Vector shapeVector = new Vector ();
public InDData (Vector shapeV)
this.shapeVector = shapeV;
public int getShapeVectorSize ()
return (this.shapeVector.size());
class InDShape implements serializable
private Vector points = new Vector();
// client side
ObjectOutputStream p = new ObjectOutputStream(new BufferedOutputStream (connection.getOutputStream()));
InDData objectData = (InDData) vectorObjectsToBeSentThroughNetwork.remove(0);
System.out.println(objectData.getShapeVectorSize(); //print 1
p.writeObject(objectData);
p.flush();
//server side
ObjectInputStream in = new ObjectInputStream(new BufferedInputStream (connection.getInputStream()));
Object oTemp = in.readObject();
if (oTemp instanceof InDData)
InDData objectData2 = (InDData) oTemp;
System.out.println(objectData2.getShapeVectorSize(); //print 2
Some explanations before the main dish :)
I am writing a client that allows you to draw a figure and send it to the network. The drawing is composed of shapes and each shape (class InDShape) is composed of points. For the drawing to be sent to the network, i add the shapeVector (== drawing) to the class named InDData (this class allows me to add some more information about the client and the object sent, not shown here) and then i write the object InDData created in the ObjectOutputStream.
Before writing InDData to the ObjectOutputStream, i test to see if it has a good shapeVector by drawing the shapeVector at the screen. This always shows the same copy as the last drawn panel.
We suppose that the drawing is sent to the network after each drawn shape
(mousePressed -> mousseDragged -> mousseReleased)
(<------------------------------- shape ------------------------------->)
now the problem ;)
When i start drawing, the first shape is sent through the network without any problem.
As soon as i add a second shape to the drawing (shapeVector.size() == 2) things get weird.
The drawing sent to the network is made only of the first shape, nothing more.
output of program after the 2nd shape was drawn
client print 1 : size is 2
server print 2 : size is 1
Alright seems like the shapeVector is truncated...
Now i tried something else to see if the it's only the Vector which is truncated or anything else.
After adding a second shape to the drawing, i delete the first shape of it:
reprenstation of the shapeVector:
([shape1])
([shape1][shape2]) // added the 2nd shape
([shape2]) // deleted the first shape
([shape2][shape3]) // added a third shape. Vector sent to the network via InDData
output of program with the vector shown above
client print 1 : size is 2
server print 2 : size is 1
Additionnaly you might expect me to say that first element of shapeVector inside both class InDData (client and server) are the same, but unfortunately they are not.
The shapeVector received by the server via InDData is the same as when i drew the first shape :((
Here is the problem (!) :(
I think that i have a variable that is not overwritten somewhere but i don't know because:
objectData is overwritten each time a message is sent to the server and has the correct values inside.
objectData2 is overwritten each time a message is received from clients.
Sorry for the huge post, but i believe that explanations are necessary ;)
I am using the 1.4.2 jvm (not tested on others) with Xcode (apple powerbook g4 12").
Thank you all :)Update :)
In my way of making my program "simple" i forgot an important point in the client side :
// client side
ObjectOutputStream p = new ObjectOutputStream(new BufferedOutputStream (connection.getOutputStream()));
while (connectionNotEnded)
synchronized (waitingVector)
try
waitingVector.wait(); // the only purpose of the Vector is to make the thread wait until it is interrupted to send InDData
catch (InterruptedException ie)
System.out.println("Thread interrupted");
InDData objectData = (InDData) vectorObjectsToBeSentThroughNetwork.remove(0);
System.out.println(objectData.getShapeVectorSize(); //print 1
p.writeObject(objectData);
p.flush();
I need it to explain the solution of my problem.
when I am creating a client, a thread is created with the above code. It creates the ObjectOutputStream and then wait patiently until said to proceed (Thread.interrupted()).
I do not close the ObjectOutputStream during the program running time.
So whenever I am writing an object to the stream, the stream "sees" if the object was created before. I suppose that the ObjectOutputStream has a kind of memory for past written objects.
So when i send the first InDData, the ObjectOutputStream's memory is "empty", thus the correct sending (and serialization) of InDData.
But whenever I try to write another object of the same type InDData containing approximately the same data (shapeVector), the ObjectOutputStream calls its "memory" and tries to find it in the past written objects. And finds it in my case ! That's why whatever i put in the shapeVector, it ends by being the first shapeVector sent through the network. (I assume that the recall memory process lacks of "precision" in identifying the memory's object or that the process to give a unique serial to the written object in the ObjectOutputStream "memory" is limited).
I tried the different ObjectOutputStream writing methods :
instead of p.writeObject(objectData) i put p.writeUnshared(objectData).
But as it is said in the docs : " While writing an object via writeUnshared does not in itself guarantee a unique reference to the object when it is deserialized, it allows a single object to be defined multiple times in a stream, so that multiple calls to readUnshared by the receiver will not conflict. Note that the rules described above only apply to the base-level object written with writeUnshared, and not to any transitively referenced sub-objects in the object graph to be serialized."
And that is exactly my case !
So i had to take it to the next level :)
instead of trying to make each written object unique, i simply reset the stream each time it is flushed. That allows me to keep the stream opened and as fresh as new ;) I think the cost of resetting the stream is higher than writeUnshared but lower than closing and creating a new stream each time otherwise it would not have been implemented ;)
Here is the final code for the client side, the server side remains unchanged :
// client side
ObjectOutputStream p = new ObjectOutputStream(new BufferedOutputStream (connection.getOutputStream()));
while (connectionNotEnded)
synchronized (waitingVector)
try
waitingVector.wait(); // the only purpose of the Vector is to make the thread wait until it is interrupted to send InDData
catch (InterruptedException ie)
System.out.println("Thread interrupted");
InDData objectData = (InDData) vectorObjectsToBeSentThroughNetwork.remove(0);
System.out.println(objectData.getShapeVectorSize(); //print 1
p.writeObject(objectData);
p.flush();
p.reset();
And that solves my problem :) -

the following applies if you have written the parent class.
you could provide a no-arg constructor. this will take care of the runtime exception. but you will see that after deserialization the member variables defined in the parent class will be set to their default values.
what you could do is make the parent implement Serializable.
there is no problem if one of the subclasses is never serialized. The Serializable interface only indicates that the implementing class and its subclasses may be serialized

Problem on serialization & Obfuscation
I really need your help, please help me.
I having problem on serialization & Obfuscation. The problem is I get back the blank object that i writen into the file after obfuscated.
I have a class A implements Serializable and using serialVersionUID.
I write the class A object to a file and able to read back the object from the file.
After obfuscation, I can read back the object from the file but the object is blank( no more data ).
Can anyone tell me what is the problem?Can anyone tell me what is the problem?Yes. There's probably a problem in your code.

I Have had my iPad for 6 months as I cannot access my work emails using windows. I have to say that it is the most unhelpful device I have ever used and although it looks like there isn't an answer for some of the questions I have asked below, I thought I would try!
1) I have upgraded to ios6 and the kindle app will open but crashes and disappears when I try to access a book?
2) is there any way I can open more than one page at a time, as opening one at a time is hopeless?
3) Is there any way you can replicate the right click function on word? As pasting and copying on the iPad is irritating to say the least!
4) why can't my Samsung 11 phone connect to my iPad via Bluetooth? A they can't seem to 'see' each other? I may have turned a setting off when I was recently abroad and didn't want huge roaming charges.
5) Why do the submit buttons on some websites not work and how can I get them to? I never have a problem with windows, but it is often a problem with the iPad.
6) I have several websites which I have built and usually upgrade on the windows desktop, usually through Internet explorer, but I can't access the sites properly on the iPad (I can see them but can't alter them) and when sending emails through the websites they won't show the page and I can't navigate the page (the size of the email page is bigger than the iPad screen, but I can't either shrink the page to size or move the page around as you normally would on the pad, any ideas?
7) finally, when roaming abroad recently, I had no problems using the wifi, but when trying to use the cellular data (using the roaming function) I could not get it to work? The ipad seemed to be connected to the network with no problems, but wouldn't actually update the emails? I tried turning it on and off, but that didn't make a difference. My kindle and mobile phone (both also on 3G ) worked great, it was just (as usual) the ipad playing up.
8) when wanting to alter part of a sentence, I can't always get the cursor in the right place? Sometimes it is simple the wrong line, but often it will only go at the end or start of a word and not where I want it. Is there any way of making it more exact? Again I never have a problem with moving the cursor on windows, either by mouse or on the touch screen function on windows 7. Any ideas? As after pressing the screen multiple times I just want to throw it out of the window!
IT might just be that I don't have the correct settings (I am a technophobe) but I absolutely hate the iPad and only have it for work emails, it is so annoying that I can get my mobile phone and kindle3g to work fine, but always have problems with the iPad. I am sure it could be good (and for reading emails on the go in the uk it is great, as I like the key board) but it just seems to make everything else difficult.
i Hope you can help and sorry for asking questions others have, but I am just hoping that something new might have been developed!
thanks,
K
Message was edited by: K Paton1) I have upgraded to ios6 and the kindle app will open but crashes and disappears when I try to access a book?
Try rebooting your iPad, that should fix he issue. I that doesn't work, delete the app and re-download it. The Kindle books should all be in he Kindle cloud services and you can get them again. I have an iPad2 w/ Kindle app and it works just fine - no issues.
2) is there any way I can open more than one page at a time, as opening one at a time is hopeless?
Page as in a kindle book way? turn iPad to landscape position from portrait position. If, however, you mean open more than one application at a time, then no. And not hopeless, as it takes a bit of time to get used to, going from a desktop/laptop format to tablet format.
3) Is there any way you can replicate the right click function on word? As pasting and copying on the iPad is irritating to say the least!
It's actually fairly easy. Press down on the word, then you can expand by drawing your finger to cover word/sentence/paragraph/page, hit select or select all then it gives you the option to cut, copy, paste, define. If you want to use a word processing app on the iPad, Pages is a good application.
4) why can't my Samsung 11 phone connect to my iPad via Bluetooth? A they can't seem to 'see' each other? I may have turned a setting off when I was recently abroad and didn't want huge roaming charges.
It's the connection on your phone. Samsung Galaxy SII? Android software? What you have to do is go to the phone's settings and connect via wireless, not Bluetooth. Go to System Settings (on phone) and under Wireless and Networks click 'more' and go to the Tethering and Portable Hotspot option. Set up your mobile wifi hotspot, name it though it will probably come up with 'AndroidAP', choose a WPA2 security level and put in a password. Go back to previous screen and turn on 'Portable Wi-Fi Hotspot' box. Then on your iPad in the Settings - Wi-Fi section, it should then recognize your phone for tethering. If it's a Windows Phone 7, I don't know the layout of that software, but presumeably similar.
5) Why do the submit buttons on some websites not work and how can I get them to? I never have a problem with windows, but it is often a problem with the iPad.
Sometimes the issue is with the website design, not all websites are optimized for mobile devices - not just iPad but also Android devices. It happens. They're getting there, but occasionally the page might need a refresh.
6) I have several websites which I have built and usually upgrade on the windows desktop, usually through Internet explorer, but I can't access the sites properly on the iPad (I can see them but can't alter them) and when sending emails through the websites they won't show the page and I can't navigate the page (the size of the email page is bigger than the iPad screen, but I can't either shrink the page to size or move the page around as you normally would on the pad, any ideas?
It depends on what you use to build the websites on the computer. Recommend a free program on the computer called CoffeeCup Free HTML Editor. I don't recommend using IE period; Firefox or Chrome are my choices on Windows machines. I have two websites that I manage, both using this program. I'm assuming that when you mean you can't access the sites on the iPad you mean to update them? Ostensible there are apps to let you do this. What format are the sites? Without seeing what exactly you mean and what you want to do, it's hard to explain.
As for seeing full page while emailing within a site, turn iPad to portrait mode, and try to finger-pinch touch the screen to see if that will bring the fuller page into view. Other option is opening a second tab with same website and just go between tabs to reference material.
7) finally, when roaming abroad recently, I had no problems using the wifi, but when trying to use the cellular data (using the roaming function) I could not get it to work? The ipad seemed to be connected to the network with no problems, but wouldn't actually update the emails? I tried turning it on and off, but that didn't make a difference. My kindle and mobile phone (both also on 3G ) worked great, it was just (as usual) the ipad playing up.
If you were outside the US or Canada, my guess is the problem lies within the SIM card in your iPad. If you were outside North America, there are different band levels - I'm guessing you have a SIM thats locked to a particular provider. Band level frequencies differ per country/continent, so a SIM card that will work in Canada/US will not likely work in UK/Europe/Asia/Australia, etc. you will be able to get your emails again when back on a wifi network. Mobile phone may have a different type SIM card (GSM/HSPA) from your iPad SIM. Also, check your email settings.
8) when wanting to alter part of a sentence, I can't always get the cursor in the right place? Sometimes it is simple the wrong line, but often it will only go at the end or start of a word and not where I want it. Is there any way of making it more exact? Again I never have a problem with moving the cursor on windows, either by mouse or on the touch screen function on windows 7. Any ideas? As after pressing the screen multiple times I just want to throw it out of the window!
Moving the cursor on a sentence is a matter of putting your finger on the screen where you want it. It's exceptionally easy to do. I'm using the Notes app to write this whole segment and I just need to put my finger where I want to change things and presto it's ready for me to change where I want it.
Here's a solution: sell your iPad (after you wipe your data off it) to someone who will appreciate it, and put your money towards the Windows Surface Tablet out later this year/early next year, where you can (reportedly) connect a mouse to it. It will have some of the Windows 7/8 functionality that you're more familiar with, or get a netbook.

I have uninstalled iTunes several times and reinstalled it on my PC running Window 7 with all updated loaded. When I click on the iTunes Store Box, Nothing happens except for a message that reads:
iTunes has stopped working.
The following items give me a choice, but no answer comes up. The computer will shut down the website.
"Check online for a solution and close the program"
"Close the program."
There is an item below the box that is selectable for View problem details. When clicked a long list of items show up. I have listed some of the problems as written, but I do not understand them. I know the iTunes Store has been available on earlier versions of of iTunes but is not on this version. How can we go back and download an earlier version of iTunes?
Here are some of the Problem Details:
"Problem signature: APPCRASH
Application Name: iTunes.exe
Application Version: 11.0.1.12
Application Timestamp: 50c8fc7e"I had this exact same problem. I found this fix and it worked for me.
Step 1:
Browse to C:\Program Files (x86)\Common Files\Apple\Apple Application Support and copy the filen named QTMovieWin.dll.
Step 2:
Browse and past that file into C:\Program Files (x86)\iTunes.
Hope this helps you. I wish I could remember where I saw this originally so I could thank them.
Good Luck.

Question
I am not able to launch FF everytime i try to open it, it says FF has to submit a crash report,and restore yr tabs. I even tried doing that and the report was submitted too, but still FF did not start, and the problem still persists, please help me solve this issue
'''(in English)'''Hi Danny,
Per my understanding that you can't get the expect result by using the expression "=Count(Fields!TICKET_STATUS.Value=4) " to count the the TICKET_STATUS which value is 4, the result will returns the count of all the TICKET_STATUS values(206)
but not 180, right?
I have tested on my local environment and can reproduce the issue, the issue caused by you are using the count() function in the incorrect way, please modify the expression as below and have a test:
=COUNT(IIF(Fields!TICKET_STATUS.Value=4 ,1,Nothing))
or
=SUM(IIF(Fields!TICKET_STATUS=4,1,0))
If you still have any problem, please feel free to ask.
Regards,

How Do I Help Apple US & Apple Europe Stop Warring With Each Other And Fix The Problem They Created?
PROBLEM
Apple will not replace, as promised, the iPhone 5 (A1429 GSM model) that they gave me in London, UK, with an iPhone 5 (A1429 CDMA model).
BACKGROUND
My iPhone 5 (A1429 CDMA model) was purchased this year in September on an existing Verizon Wireless (VZW) line using an upgrade. The purchase took place in California and the product was picked up using Apple Personal Pickup through the Cerritos Apple Retail Store. I will refer to this phone at my "original" phone.
The original phone was taken into the Apple Store Regent Street in London, England, UK on November 15, 2012. The reason for this visit was that my original phone's camera would not focus.
The Apple Store Regent Street verified there was a hardware problem but was unable to replace the part.
The Apple Store Regent Street had me call the US AppleCare. At first they denied support, but then a supervisor, name can be provided upon request, approved the replacement of my original phone with an iPhone 5 (A1429 GSM model) as a temporary solution until I got back in the US. And approved that the GSM model would be replaced with a CDMA model when I came back to the US. I will refer to the GSM model as the "replacement". They gave me the case number --------.
The Apple Store Regent Street gave me the replacement and took the original. The first replacement did not work for reasons I do not understand. They switched out the replacement several times until they got one that worked on the T-Mobile nano SIM card that I had purchased in England, UK. Please refer to the repair IDs below to track the progression of phones given to me at the Apple Store Regent Street:
Repair ID ----------- (Nov 15)
Repair ID ----------- (Nov 16)
Repair ID ----------- (Nov 16)
The following case number was either created in the UK or France between November 15 to November 24. Case number -----------
On November 19, 2012, I went to France and purchased an Orange nano SIM card. The phone would not activate like the first two repair IDs above.
On November 24, 2012, I went to the Apple Store Les Quatre Temps. The Genius told me that my CDMA phone should not have been replaced with a GSM model in the UK and that this was clearly Apple's fault. They had me call the AppleCare UK.
My issue was escalated to a tier 2 UK AppleCare agent. His contact information can be provided upon request. He gave me the case number -----------.
The UK tier 2 agent became upset when he heard that I was calling from France and that the France Apple Store or France AppleCare were not helping me. He told me that my CDMA phone should not have been replaced with a GSM model in the UK and that this was clearly Apple's fault.
The UK tier 2 agent said he was working with engineers to resolve my problem and would call me back the next day on November 25, 2012.
While at the Apple Store Les Quatre Temps, a Genius switched the phone given to from repair ID ----------- with a new one that worked with the French nano SIM card.
Also, while at the Apple Store Les Quatre Temps, I initiated a call with AppleCare US to get assistance because it seems that AppleCare UK was more upset that France was not addressing the issue rather than helping me. I have email correspondance with the AppleCare US representative.
A Genius at the Apple Store Les Quatre Temps switched the replacement with a new GSM model that worked on the French SIM card but would not work if restored, received a software update, or had the SIM card changed. This is the same temporary solution I received from the Apple Store Regent Street in the UK.
By this point, I had spent between 12-14 hours in Apple Store or on the phone with an AppleCare representative.
Upon arriving in the US, I went to my local Apple Store Brea Mall to have the replacement switched with a CDMA model. They could not support me. He told me that my CDMA phone should not have been replaced with a GSM model in the UK and that this was clearly Apple's fault. My instructions were to call AppleCare US again.
My call with AppleCare US was escalated to a Senior Advisor, name can be provided upon request, and they gave me the case number -----------. After being on the phone with him for over an hour, his instructions were to call the Apple Store Regent Street and tell them to review my latest notes. They were to process a refund for a full retail priced iPhone 5 64BG black onto my credit card so that I could use that money to buy a new iPhone 5 64GB black at the Apple Store Brea Mall to reoslve the problem.
The Apple Store Regent Street did not process my refund. He, name can be provided upon request, told me that the AppleCare US did not do a good job reviewing my case, that they were incapable of getting to the bottom of it like they were, and instructed me to call AppleCare US and tell them to review this case number and this repair id. I asked if he read the notes from the AppleCare US Senior Advisor and he would not confirm nor deny. When I offered to give him the case number he accepted but it seemed like would do no good. Our call was disconnected. When I tried calling back the stores automated system was turned on and I could not get back through.
Now I have the full retail price of an iPhone 5 64GB black CDMA on my credit card and Apple will not process the refund as they said they would.
I've, at this point, spent between 14-16 hours at Apple Stores or on the phone with AppleCare representatives, and still do not have the problem resolved.
SOLUTION
AppleCare US and AppleCare Europe need to resolve their internal family issues without further impacting their customers.
Apple is to process a refund to my credit card for the cost of a full retail priced iPhone 5 64GB black.
DESIRED OUTCOMES
I have an iPhone 5 (A1429 CDMA model) that works in the US on VZW as it did before I received the replacement phone in the UK.
Apple covers the cost of the solution because I did not create the problem.
Apple resolves their internal issue without costing me more time, energy, or money.
This becomes a case study for AppleCare so that future customers are not impacted like I have been by their support system.
Does anyone have recommendations for me?
Thank you!
<Edited by Host>Thanks, but I've been on the phone with AppleCare US (where I am and live) and AppleCare UK. They continue bouncing me back and forth without helping resolve the problem.
Perhaps someones knows how to further escalate the issue at Apple? -
This is regarding a brand new ASUS PA 279Q, 2560 x 1440 IPS monitor. I'm connected via mini display port (into thunderbolt port on MacBook Pro) to display port on ASUS monitor; using cable ASUS included with the monitor. Mid 2012 MacBook Pro…full specs at bottom of this post.
I have resolution set at 2560 x 1440 which is the native resolution according to the ASUS spec. I tried the other resolutions available in my System Preferences and text displayed rough with those settings too. I've tried adjusting contrast, brightness and sharpness via the ASUS control panel and didn't solve the problem. Also tried calibrating via Mac's system preferences/display and that did not improve text display either. All the text on this monitor (no matter what software I launch, Finder, InDesign, Illustrator, MS Word, Excel, VMWare Windows XP, Windows versions of Word, Excel, Acrobat, etc, all are consistently rendering text the same way --- ROUGH and with "HALOS" around each letter.
All point sizes of text and at various scales, display very rough on the screen. (My comparison is the retina display of my MBP and a Thunderbolt…so those two displays are my expectations.) I'm using the same MBP for both a Thunderbolt display (at work) and this ASUS at my home office.
On the ASUS it's not as noticeable when the text is on white backgrounds, but I'm a graphic designer and compose images with text all day everyday. Not to mention the specs on this ASUS PA279Q indicate it's built for the professional so I would expect better text rendering. I haven't even addressed color calibration and balance yet, because that won't matter to me if the text won't display any better than it is now.
I was so hopeful after researching all the specs on this monitor it would be a viable alternative to the glossy display of the Thunderbolt display. (Which, I do love the Thunderbolt display for it's clarity and how it displays crisp, clean text at all sizes. (This ASUS actually displays text decently if I increase the text so each letter is about 4" high. Which is pointless for practical purposes -- that'd be like doing page layout through a microscope!)
I kept holding off on getting a monitor for the home office thinking the Thunderbolt would be updated soon. I'd be sick if I dropped a grand on piece of 2011 technology only to learn a few days later an updated Thunderbolt display hit the market! Not to mention, I'm praying Apple comes out with a less reflective Thunderbolt display. The glare and reflection is the main reason I looked elsewhere for a large monitor; hence my asking for help. Hoping the ASUS text display issue can be worked out. My expectation is for it to display like the MBP retina and Thunderbolt display text. That possible?
Alternatively, I guess I could do the Apple Refurb Thunderbolt at $799. And see if there's a decent aftermarket anti-glare I could stick on it?
Thanks for reading my post. Hope someone can help; offer any suggestions? Words or wisdom?
Has anyone else had similar issues and figured out a resolution? Help!

ASUS PA279QI uninstalled those two items. It still runs slow on start-up and when opening safari, firefox, iphoto, itunes, etc. It's not snappy like it used to be. Any other ideas? Thanks.

Youll get that message when you change the iTunes account you are logged into, you can't keep changing it. -
Can you please take a look at my TM Buddy log and opine on what the problem is?
Pondini,
Can you please take a look at my TM Buddy log and opine on what the problem is? I'm stuck in the "Preparing Backup" phase for what must be hours now. My last successful backup was this morning at 7:16 am. I did do a series of Software Update this morning, one of which, a security update I believe, required a restart.
I'm confused as to what the issue is, and how to get everything back to "it just works".
Many thanks in advance.
