Additional display makes flat panel blurry

I used the external vga adaptor to send a video signal to my television. When I did this it seems to have automatically done something to my imac display. The video looks good on the TV, but now the display on my imac is stretched and blurry. I am not sure why this change happened instantly when i hooked up the vga output. Can anyone talk me through getting my display back to normal?

The resolution is changed for television. Unfortunately, in order for the quality to look good through the VGA output, your iMac display does not. The VGA out mirrors the display, so they are not independent. Therefore, in order for the VGA out to work, the output from your graphic card is changed on both the iMac display and VGA out... I don't think that there is a way around this...
Anyway, your iMac display will return to normal as soon as you unplug the VGA adaptor.

8800 GT vs. new Apple LED Cinema Display (27" flat panel)

I would like to buy the new Apple LED Cinema Display (27" flat panel), however, have no idea if it is compatible with my Mac Pro. Bellows are the details of my desktop...
Mac Pro (MacPro3.1) Quad-Core Intel Xeon 2.8 GHz * 2 (8 cores), with 12 GB DDRII 800 MHz.
Graphics cards for Mac Pro (Early 2008): NVIDIA GeForce 8800 GT (part number 630-9191 or 630-9897)
If it's not compatible, could someone let me know how to upgrade of what to make it work?
Thanks!
PJ

Doesn't look hopeful.
Apple LED Cinema Display 27"
http://store.apple.com/us/product/MB571Z/A
Obviously the ATI 5770, once it ships, will work.
Apple Display tech note only addresses ATI 5xxx and only 2009-2010 Mac Pro models.
http://support.apple.com/kb/HT4279
Cutting off anything two years old, is now 'legacy'? I don't think they hope to sell their 27" to older Macs or PCs.
In the product Q&A:
*This looks great! Does this work with PCs?*
Yes, but you'll need an adapter with a mini-displayport like the top of the line Radeon 5970 (they all have one MDP), or one of the 5870s specifically designed for Eyefinity (multiple displays). Search Newegg under graphics cards (advanced) and filter only cards with mini displayport. No other PC cards on the market, including Nvidia seem to have mini-displayport. It's a good interface, but I fail to see why Apple decided to loose customers to support it exclusively.

Difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)?

May i know the difference between a Apple LED Cinema Display (27" flat panel) and a Apple Thunderbolt Display (27-inch)? both products look the same to me, even the prices are the same, but the name of the product is different. Its so confusing! I want to purchase a secondary display for my 21" iMac, but idk the difference between the two.
furthermore, another question i have is, is 27" the largest display i can get? is there larger ones (just the screen, not the computer)?
please help, thanks!

One has thunderbolt capabilities, the other doesn't.

No you can get a larger one. Maybe not an Apple one, but certainly another brand.

Flat Panel Causing Speaker Humming Help Needed!!!

Hey, I got a question. I got a mac book pro and I got the mbox pro 2. I also got a apple hd display 23 flat panel and Event ALP 5 speakers with a S100 Sub. When I first hooked everything up, I started getting a humming sound from the speakers. So I thought it was that I had bad wires connect to the speakers. But I found out that wasnt the problem. So by accident, I miss and unplug the cord hooking the 23" flat panel from the mbox pro. So when I did that, the huming from the speaker stoped. So can you help me, cuz i wanna be able to hook up my 23 flat panel to my mbox without the speaker huming.

Well, I'll at least give you points for neatness. However, that is about it.
I didn't really look through all of your logic but I would highly recommend that you check out the examples for implementing state machines. Your application suffers greatly in that once you start you basically jumped off the cliff. There is no way to alter your flow. Once in the sequence structure you MUST execute every frame. If you use a state machine architecture you can take advantage of shift registers and eliminate most of your local variables. You will also be able to stop execution if necessary such as a user abort or an error. Definitely look at using subVIs. Try to avoid implementing most of your program in formula nodes. You have basically written most of your processing there. While formula nodes are easier for very complex equations most of what you have can easily be done in native LabVIEW code. Also if you create subVIs you can iterate over the data sets. You don't need to duplicate the code for every data set.
I tell this to new folks all the time. Take some time to get comfortable with data flow programming. It is a different paradigm than sequential text based languages but once you learn it it is extremely powerful. All your data flow to control execution rather than relying on the sequence frame structure. A state machine will also help quite a bit.

Is it possible to use old Apple Flat Panel Display (62 watt power adapter) with MacBookPro 13" Mid-2012 running 10.8.4? Tried mini display to VGA cable

Is it possible to use old Apple Flat Panel Display (62 watt power adapter) with a MacBookPro 13" Mid-2012 laptop? Would like to use larger screen when working at home. I have a mini display port to VGA cable and have tried to hook up the old display but it seems not to work. When I try to activate the screen on the old display-- a window comes up in the MacBookPro and asks me if I want to shut down the computer. What little I have read it that the MacBookPro had Thunderbolt and the old display may not be compatible? Any assistance would be appreciated.

11.09.12 22:16:06,148 ClamXavSentry[286]: I will quarantine infected files
This doesn't have anything to do with your problem, but it will likely cause other issues with your e-mail.
Here's my standard recommendation concerting the use of A-V software to deal with potentially infected messages:
Never use ClamXav (or any other A-V software) to move (quarantine) or delete e-mail. It will corrupt the mailbox index which could cause loss of other e-mail and other issues with functions such as searching. It may also leave the original e-mail on your ISP's e-mail server and will be re-downloaded to your hard drive the next time you check for new mail.
So, if you choose to "Scan e-mail content for malware and phishing" in the General Preferences, make sure you do not elect to either Quarantine or Delete infected files.
When possibly infected e-mail files are found:
Right-click/Control-click on either the infection or file name in the ClamXav window.
Select "Reveal In Finder" from the pop-up menu.
When the window opens, double-click on the file to open the message in your e-mail client application.
Read the message and if you agree that it is junk/spam/phishing then use the e-mail client's delete button to delete it (this is especially important when the word "Heuristics" appears in the infection name).
If you disagree and choose to retain the message, return to ClamXav and choose "Exclude From Future Scans" from the pop-up menu.
If this is a g-mail account and those messages continue to show up after you have deleted them in the above manner, you may need to log in to webmail using your browser, go to the "All Mail" folder, find the message(s) and use the delete button there to permanently delete them from the server.
To fix the corrupted mailbox index(es), highlight each one that was corrupted and choose Rebuild from the appropriate menu.

Supported flat panel displays for an ATI Rage 128 Pro/G4 500

I originally was using an Apple 21" CRT display with my G4/500 until the display's picture tube failed. I am now looking to purchase a flat panel w/DVI, using my G4's DVI video port and the Rage 128 Pro card. I have found conflicting information on resolutions supported by the ATI card. I am looking at a Dell UltraSharp 2005FPW 20.1-inch Wide Aspect Flat Panel LCD, and the requirements indicate that my system must be able to support WSXGA+ resolution (1680 x 1050). A 24" version of the Dell monitor requires the support of WUXGA resolution (1920x1200). WIll either of these flat panel monitors work with my G4? If not, what specs do I need to look at to determine compatibility? Thanks.
Apple G4 500 Mac OS X (10.3.1) ATI Rage 128 Pro Graphics Card

Hi JBernstein,
Karl,
I greatly appreciate your efforts to resolve my
question.
No worries, Mate!
To address a question you posed earlier, no, my G4
did not come with a ADC port. I have both VGA and
DVI-D ports on my G4/500 (Graphite) with the Rage 128
Pro ADP card, which is 16 mb and 2x.
From that, I would infer that you computer is not ADC enabled.
It was the Genius at
the Apple Store who mentioned the Radeon 9000 card as
a replacement. but he also suggested that the current
20" Apple display would work with my G4 ... we tried
that today, and the OS would not launch and power the
display. SO, we must replace the card, or live with
small displays.
Yes, the ATY 128 Pro generally does not have enough grunt to power the larger displays.
I did find a number of Radeon 9600 Pro Mac Edition
video cards on eBay, but most had a published spec of
4X, and the response to whether it was backwards
compatible with the 2x capability in my G4/500 is
that it will not work. Is that true?
All the information I have (via the ATI website) does not specifically state that the 9600 card will support AGP 2X. Other ATI cards that do support 2X have this specifically stated in the information. Therefore, there is no garauntee that the 9600 card will support 2X. Until I receive information that someone has used this card in an AGP 2X computer with success, I cannot advise trying to use it.
I have not
confirmed the Radeon 8500 as yet, but as you might
imagine, it is frustrating to get conflicting
responses.
The ATI Radeon 8500 will work in your computer (as, partially, will the 9000 - refer to my earlier posting).
Perhaps you might address a different question ... is
there any place within Apple that I can go, even with
paying a fee for services, that would definitively
provide an absolute solution to an upgrade type
question, complete with exact part number AND
guarantee that the information is quite accurate? Why
wouldn't Apple provide some type of infomration on
replacement/upgrade path for older products (geez ---
the G4/500 Graphite isn't even on the legacy products
list yet) so that the customer can invest and upgrade
without going through a challenging process to get
the right information? The information I've turned up
is vague and not geared towards solutions like this.
Apple, for all sorts of reasons (legal and commercial), is loath to provide "official" advice on the use of any third party upgrade hardware on their products. Moreover, discussions on the morality of this is probably against the terms and conditions of this discussion forum.
I'm all ears as to how to move forward with this G4
with a replacement card, if that is possible.
The way I see it, you need either an ATI 8500/9000 if your only desired upgrade is the capacity to run larger displays, or an ATI 9800 is you wish to do gaming, graphics and be able to make full use of all the new Tiger graphics facilities.
Cheers!
Karl

Upgrade SNAFU - MDD/ATI 9800 Pro/Flat Panel Display

I've been adding to my MDD and been caught overlooking the fact that my Apple ADC monitor doesn't connect to my ATI 9800 Pro. ADC, DVI, VGA .... whats next
Anyway, is there a connector or adapter I can get to 'bridge' this last hurdle?
Sometimes with Google you need to know exactly what you are looking for in order to get the right results. My results didn't produce what I was looking for.
Thank you

Go to the Apple Store, look under "Displays". Then look for the "Apple DVI to ADC Display Adapter". Costs $99. But that's what will do it with LCD ADC displays. Dr. Bott used to make (and may still make) the DViator which accomplishes the same thing. Both have big bricks which supply the juice to your ADC monitor -- in fact the DVIator uses the PSU for a Cube.
I mention LCD monitor with ADC because both don't work the ADC CRT monitor. I know you have flat panel in the subject of your post; I mention that for other who might come across this thread.

Mac Mini to G4 iMac Flat Panel display ???

Just scanned some pages back in this forum and couldn't see this as a topic-so I'll ask.
I was wondering, if I had a 17" Flat Panel imac (even the 800Ghz version, or the 1Ghz or the !.25Ghz - or event the 20" [yummmmy] ) could I drive the mac mini via the iMacG4's highly versatile flat panel display ???
[ideally I'd love to be able to re-engineer the Flat Panel's guts with smaller but faster CPU etc - and as machine innards get smaller maybe this will be possible - because the screen tilt and swivel is so versatile; eh!)]
gregg

Hmm - why did myinnermostthoughts sudenly become a hyperlink - or is it a hyperjump into the final frontier of cyber-computing???
Anyway, but I had hoped to just plug a keyboard into 2005 'Twiggy" , use a VGA adaptor/er between the two machines, and use the 1.42 Ghz speed of the 'Twiggy' to display stuff (CS2 etc) on the Flat Panel's display (oxymoronic word usage here - I suppose). The Flat Panels do have an vga port - so why cant the cable go from the mac mini to the VGA port of the iMac ??? Are you saying ti's almost impossible - or are you refering to re-engineering???

How to combine 17" iMac G4 flat panel display & iBook G4

I have a 17" flat panel G4 800 iMac. Monitor works fine. The logic board is toast.
I have a 14" G4 1.33 iBook that works perfectly but the screen is broken.
I want to attach the 17" flat panel to the VGA adapter on the iBook so I can see the desktop. I plan on using the iMac to power the monitor.
I have found the adapter & cable that attaches to the logic board for the video input for the 17" monitor.
The key bit of information that I need to know is what wires from the 17" monitor cable needs to attach to which pins on a VGA adapter?
I haven't found the info I need in either the iMac or iBook categories on Apples Discussion Board or searching other Mac friendly web sites.
Thanks in advance for any help or direction you can give.

You could try asking around to see who needs your iMacG4 for parts;
since you should be able to get almost enough from the good display
alone to buy a LCD monitor or one with a TV tuner to use with the iBook.
The prices of LCDs have come down a bit; not sure if you'd need to try
one of the ResX kind of software fixes to be able to use different resolution
LCDs with your little iBook. Costco had a 22" LCD for under $350; so a
smaller one may be available in the $180. range. Some with TV are coarse.
In some markets, the LCD from your iMacG4 in great shape and working
can be worth over $350. and if you lucked out, someone out there may
have a refurbished logicboard. Sometimes wegenermedia and other co's
that repair iBook/PowerBook out-of-warranty machines also have iMacG4s.
Some also have pulled but high quality used iBook displays.
The LCD for the iMacG4 requires a power supply and other circuits, those
are part of the base unit's video/logic board assembly and power supply.

Can Powerbook connect to sony LCD flat panel fo simultaneous display?

I want to buy the Sony KDL-52XBR2 LCD flat panel and connect my Powerbook G4 using an HDMI or HD-15 Pin cable for simultaneous display.
While the TV specs say it will allow a PC to connect and display, I have had trouble in the past with Mac/tv connectivity because of video driver issues in either the Powerbook or the tv. I could not get both screens to display simultaneously (without parts being cut off at the bottom or sides). Apple would not support my question as the "connected device" (the tv) was not an apple product.
Before I spend the money on a new TV, I would like to know if anyone has had success with "plug-and-play" connectivity to a 42" or 50" plasma or LCD flat panel, in particular a Sony product.
Thanks in advance for sharing.

There is no reliable way to know if a random TV will or will not suffer from the "overscan" problem where the top, bottom and sides are cut off. Many TVs do this and there is no way to get around it.
What I would do is take your PowerBook to the retailer where you are buying the TV and ask them if you can hook up the PB to the floor model. That is the only way to know for sure if it works to your satisfaction. Either that or, if you have a specific TV and know its model number, you might be able to ask your question again and get an answer from someone that already owns the TV. The AVSforum.com are a good place to check for various TV models.

Picture too large for 20" Flat Panel display

Mac Pro, CTO 2 x 2.66 Ghz dual-core Intel Xenon with 20" flat panel display.
Running OSX 10.6.3
All of a sudden, yesterday, the picture became too big for the screen. Bottom, top, and sides of display are all off screen. Moving cursor to edge moves the picture so that you can get to edge of picture. Display enlarges after login. I have had windows hide the top menu bar so that the menu bar can not be accessed. I have had windows get so large that the red, yellow, and green buttons could not be accessed as well as the resize location at bottom right. Had to shutdown by holding down the on button on the computer. The resolution of the monitor is now lower. I am using 1680 x 1050 resolution, but changing to lower resolutions does not solve problem.
Is it a software problem, or is the monitor going bad? What can I do?

That fixed it! I had forgotten all about that feature. I must have done it accidentally with the mouse. Thank you very much!

Blue thin line on the lower left iMac G4 Flat Panel

Hi, since yesterday there is a blue thin line (0,039 inches (1 mm) thin; 35 inches (9 cm) long on the panel of my iMac G4 Flat Panel. It looks like drawing with a ruler, so straight and so fine.
The line is on the left lower corner in a vertical position. At first I thought these are dead pixels, but I checked this. No dead pixels. I have changed the desktop picture etc., but it`s all the same. I run the apple hardware-test cd - no problems found. Is there someone with any idea? Is it possible to have a damaged graphics- chip although the hardware-test is o.k.?
Does it make sense to open the iMac and look for dust and dirt on the motherboard?
Thank you for any help, Matse

What happens if you change the
display resolution? (Apple Menu > System
Preferences... > Displays > Display tab >
Resolutions) If the line stays in exactly the same
place despite the resolution change this points to an
LCD rather than graphics card issue.
mrtotes
thank you Adam for that hint. The line stays exactly in the same place. That means it is an LCD issue? That´s your opinion? Do you have any idea if it is possible to repair it, or is the only possibility to change the panel?
Thank you, Matse

Powermac 8500 Flat Panel Monitor Options

I have a PowerMac 8500 and my Apple Multiple Scan 15 monitor is making noises, the green power button flashes, the image distorts bowing inward on the left side, or the screen doesn't light up at all.
What Apple branded flat panel monitors can be driven by my computer? The Mac 8500 has a DB 15 connector, I believe.
Would I need an adapter to connect the flat panel display, and which adapter?
I have 2 Apple Flat panel 17"? monitors that came with my G4's I could test, if I had an adapter. Is this a good idea?
Thanking you in advance.

You don't need to buy an Apple display. Any brand LCD display can be used with a Mac, provided that the computer had adequate graphics support for it, with a suitable hardware interface. If you buy a used display, be sure that it can be returned if there are any problems (like dead pixels). When you consider the initial cost of shipping and possible cost to return a bad display, I'd be reluctant to buy a used one at eBay. Many sold there are high-mileage units pulled from corporate use. If there are any retailers in your area selling used computers, I'd check with them first. At least you'd get to try it out before buying and avoid shipping expenses. Otherwise, the prices of new displays have dropped so much that buying one for your 8500 isn't money wasted, since the display can be used with any newer computer that you might purchase.
Have you ever added VRAM to your 8500? It shipped with (2) factory-installed 1 MB VRAM cards, and is maxed out at 4 MBs with an additional pair of 1 MB VRAM cards. You might want to consider installing a Mac-compatible PCI graphics card having onboard SGRAM or DDR-memory, to provide better performance for a newer display. If you go with an older graphics card, you'd be better off buying a display with the standard 4:3 aspect ratio - like your old Apple display. The optimal resolution setting for a widescreen display (16:9 aspect ratio) may not be supported by older graphics cards. Two old (but still good) graphics cards are the ATI Rage Pro (8 MBs of SGRAM) or the ATI Rage128 (16 MBs of SGRAM). Both of these cards have a VGA port, eliminating the need for an adapter. You could find these for very little at eBay - but they must be Mac-compatible versions. Cards pulled from PCs aren't compatible, unless they can be re-programmed with a Mac ROM. A newer graphics card, like the Radeon 9200, would be capable of supporting any modern display, but costs more than your 8500 is worth. That's when you should consider investing the $$ in a slightly newer, used Mac (like a G4 tower) with AGP graphics.

HP flat panel monitor - does it need a driver?

Can I just check if it is necessary to install a different driver for a HP flat panel monitor, as I tried to connect a HP 19 inch display and the display looked a little fuzzy, certainly not as clear as when it had been displaying from the old PC. Thanks in advance

No drivers should be necessary. Check the Display system preference and make sure the monitor is being driven at it's default (maximum) resolution. Some monitors don't auto-detect correctly, so your Mac may not have set (or even recognized) the correct resolution.
Hope this helps.
