External display jitters, only when I drag a window, or switch apps.

I just purchased a brand new HDTV, and hooked up my computer to it via HDMI. The picture looks great, high resolution and everything. The problem is that when I move a window on the display, all the lines/letters all jitter/vibrate a little bit, before becoming totally focused. It's only a fraction of a second, but it is very annoying/distracting.
I have Windows installed on a partition, and when I am running Windows, this does not happen.
Thanks,

How do I put an external display to sleep when I am using my MacBook Air for presentation?

How do I put an external display to sleep when I am using my MacBook Air for presentation? I do not want to go to the projector just to turn it off and turn on again after a while? Is there a keyboard shortcut for that?

I want to be able to sleep the external display and at the same time do things in the MacBook.( This feature is useful for me so that I can prepare some things and so that my audience will not see what I am about to show them.)
Is there a feature for Mountain Lion?

If you subscribed to iTunes match the songs are kept in icloud. If you didn't but you did save the actual iTunes library folder which should include the music, video, etc. you should be able to just drag this file back to your machine in the same place and when you open iTunes it will give you a chance to identify the iTunes library folder.
You can test this to find out if you saved the media files or not and don't need to attach your nano to do it.
You are correct that once you connect the nano it will clear the existing files from it and sync it with the new iTunes library.
If you don't have the media files i'm not sure if/how to get them back on a windows ipod. I have everything backed up regularly because of the horror stories I have seen & heard.

External display turns off when macbook isn't charging...

I have my old 2007 white Macbook hooked up to an external display. Recently I have been wanting to calibrate the battery while using it on the external display, but every time I remove the charger from the Macbook the external display will stay on for a couple of seconds then turn off, it will only come back on when I click the mouse or press something on the keyboard, but then it will go back to sleep. Note: when my Macbook is connected to the external display I keep the screen closed.

When you are looking at the displays in the System Prefs, all you have to do is click and drag the tiny rectangular bar from the main screen to the external monitor screen (this designates the primary monitor).
Once you've done that, all you have to do is close the lid. Your screen will flash a couple times, but the external monitor will then remain on and working, and you dont need to keep your lid open.
FYI, I would turn down the brightness of your MBP down all the way (for both the screen and keyboard). I have found that this reduces any heat build up that it may have from running with a closed lid.
Hope this helps!

Coverflow causes external display to flicker when rotated

Hi,
I have a new MBP 15", 2.2GHz, 2GB with Leopard installed, and I have an external monitor (a Lenovo Thinkvision L201p) which can be rotated into portrait mode, and that is how I use it almost all the time.
The problem I have is that whenever I browse something using coverflow, be it in the Finder or in iTunes, the external display flickers (sometimes quite badly) as the items move. This happens even if the application that is using coverflow is on a different space (for example, if I have iTunes on a different space and it switches to a different song). It only happens when in rotated mode, in landscape mode the flickering goes away.
Does anyone have any ideas what could be causing this? Maybe an issue with the video driver? Can someone reproduce this?
Thanks.

This was solved in 10.5.3.

External display issues only at 1920x1080

Hi,
I've been using a small LCD monitor with a mini displayport - vga converter. Today I've bought a LED monitor that can handle 1920x1080, and its only input is VGA. Once I hook the monitor up, I get a `no signal` display. I then change the resolution to 1440x900, it works fine. I then change it back up to 1920x1080, get no signal, then after about 5 secs get display. Now, the main problem is that the main monitor goes awkward after arbitrary time period. I've taken a screenshot (yup) of the display. If i switch back to 1440x900 and then switch to 1920x1080 again it goes fine. I've resetted the PRAM. All this happens on a early 2011 Macbook Pro 13".
Any ideas?

There have been similar reports. However, not all external displays in combination with a MacBook will exhibit this problem. Thus, it seems either display specific or something that is caused by a cross between one display and a MacBook.
I assume that you are using one of Appe's mini DisplayPort to DVI adapters to connect to the external display. In that case have you installed the latest firmware update for the adapter?

Why does Adobe Reader XI set my keyboard to display NUMBERS ONLY when I open a .pdf file?

I need to keep re-booting my laptop to resolve above bug. Ideas please?

ONE MONTH AND NO REPLY - WHO CAN ADDRESS THIS BUG????
WHEN I OPEN A .pdf document using ADOBE READER 11.0.2 BEHAVIOR is described BELOW. I CANNOT BE MORE COGENT.
It occurs both within Adobe Reader functions, such as page printing options, and in all APPLICATIONS (Gmail, Word, etc) once I close .pdf document.
SOLUTION: I MUST POWER DOWN/UP EACH TIME I USE ADOBE READER. THIS IS IDIOCY.
1. Keyboard appears RESET to display numbers ONLY, and numbers displayed to DO NOT CORRESPOND to numbers I TYPE.
AFTER ADOBE READER IS CLOSED I type "A" into say, an email address field and a random number, say, "9" appears in the field not an "A".
WHILE IN ADOBE READER I type "23" into the .pdf "go to page" field, and get other numbers completely.
Happens ONLY when I open a .pdf file with Adobe Reader 11.0.2 (XI).
Both behaviors occur whether I open a download .pdf file or attempt to open a .pdf via search engine Google + my Browsers.
2. Operating System = Windows 7.
3. My Browser = Internet Explorer 9 or Mozilla Foxfire; behavior is identical on either. Search engine used is Google.
Weird, but true, and tiresome. I've had it..

MBP still thinks external display is connected when it's not

I have my MBP connected via DVI to an external LCD (HP w2007). Whenever I disconnect the DVI plug from my MBP, my MBP thinks the external monitor is still connected. I can go to Sysprefs > Displays > Gather Windows and it'll clearly have the HP's display pref window showing up.
This is a huge issue since any programs that were previously shown on the external display continue to think the display is still there and then I can't access them.

Had posted here because I figured the hold time for Apple support would be long because of Leopard's release. Hold times were not too bad. Problem is solved by resetting PRAM.

Screen moves very slow when i drag a window from one corner to other.

Hi,
We are taking RDP to windows server 2008 R2 standard using Thin-clients.
If I drag a window of explorer or browser to other end of screen it is very slow.(it will work as desktop without video drivers).
Is there any solution for this.
And By the way what is application getting accelerated mean.
Thanks in advance...........

Hi,
Please check if a normal physical computer has the same issue. If not, I’m afraid that the issue is related to the performance of Thin Clients.
Please update the firmware and drivers of your thin clients to the latest and try again.
Thanks.

Some apps crash out when I close their window and switch to the Finder

It has been doing this since day one. I'm a college student and bought a laptop to replace another really old mac system, to use as my main system. The issue I'm noting is that on some apps, if I close out their window and switch to the Finder, by either click on the desktop, or by command tabbing. The application seems to crash. I say 'seems' becuase I'm not certain it's crashing. It does this in Text Edit along with pages. I'm trying to find out if it's supposed to this or if it's supposed to be a new feature. There is never a crash log made that I know of, nor a dialog box stating the app crashed. However, it does this by itself, without my quiting out the app by command q nor file>quit.
This has been relatively minor and hasn't caused any large problems. To me it's an annoyance and inconviencning. Which is why I waited until summer break at school to investigate. Other classmates with older mac book pros but the same OS version have not had this problem. Wondering if I have a botched isntall of OS X from the factory. I've already had it in for service for the motherboard. The cooling system was not correctly attached to teh CPU at the factory and cooked itself.
I'm tempted to do a reload of the OS from the diagnostics partition the system came with. I haven't transferred much of anything from the previous system that this one is replacing. Now would be an ideal time to do anything of this nature rather than say in the middle of next semester.
The issue occurs in TextEdit, Pages, and that's it so far. I really have almost nothing loaded on the system. I dual boot into another OS for using Maya and other various software apps. The issue does not occur with Safari nor FireFox nor Preview. It seems confined to Pages and TextEdit. It can be extremely annoying however when typing an essay in Pages. Perhaps it's a feature that was introduced that I can turn off? Going from a 5 year old Mac Mini to a MBP, LOTS has changed.

Sorry for taking so long to reply. It's still doing it. I'm kind of wondering if something like a preferences file is corrupted, however, I have to do a total system reload to begin with to eliminate any potential corrupt data on the windows 7 install.
Back story. When I first got this thing it was running super ridiculously hot. It's the first laptop I've ever owned however so I had nothign to use for reference. After about two months of it getting brutally hot, it did a BSOD in the windows 7 install I did via bootcamp. It never turned back on. Took it to the Apple store in Novi MI and they stated it somehow ran so brutally hot the CPU did a solder reflow and the whole motherboard shorted out. Even worse though, I had gotten this hot before rendering stuff in Maya and Vue. I had done burn in tests when I first received the system, it had passed, or so I thought. They couldn't even get the system to turn on at the Apple Store.
The tech at the apple store told me that one of the heat sink pins on the CPU just plan broke off and another wasn't attached correctly. Essentially the system kept overheating as I was consisently completely maxxing out the system doing CGI test renders for my junior animated short film. The cooling system was never fully connected at the factory according to the Apple Tech. I don't know how literate everyone reading this is on computer engineering but, when you overheat an IC, whether it's an ASIC or CPU, they dont' immediately crash, they corrupt data. To further complicate the mess and increase teh chances of data corruption, with the 4th gen Intel i series CPUs (which the MBP uses), they moved the northbridge directly into the CPU die. So if teh CPU is overheating, the chances of data corruption inadvertantly go up even higher. I'm suspecting that happened in the first few days of owning the system but that it was minor at that point. It can take months for the effects of corrupted data to propagate out and be visible to the user.
I would assume that they did a diagnostic test on the SSD when it was in for service, to ensure the SSD didn't overheat. The tech did state that if the drive failed the diagnostics, they would have ot replace the drive and henceforth all my data would be gone. Not really a way around it.
Currently under the windows 7 install with Maya and Vue, later iterations of the scene file, from Maya, for my animated short film, have a reproduceable glitch involving a gamma shift and camera selection. Part of the scene files seem to be corrupt and were saved that way.
Reloading the OS from the recovery partition did not fix the original problem I've been having that I initially asked for help with. I'm considering wiping out the recovery partition in addition to reinstalling windows 7 and OS X again, it would be the only way to completely eliminate the possibility of any corrupted data floating around on either partition. I don't have a way of knowing if corrupted data was written to the SSD beyond the corrupted Maya scene files. The only way I can be sure that it's 'contained' or eliminated, is if I completely wipe the drive and start from scratch. Now would be a great time rather than in the middle of working on my senior thesis for my BFA degree.
I'm wondering if you could point me to documentation showing how to wipe out all the partitions, including the recovery one. My understanding is that there is a way to do a 'net boot' or 'net recovery' over a broadband connection using Apples servers. The idea of doing a Live boot from a Ubuntu distro to run fsck is appealing but it would be pointless. The file system shoul be fine, it's the data the file system points to that I suspect is corrupted at somepoint. Unless you recommend otherwise and or formatting.
The overheating also corrupted my journal but there is no way to recover it, I overwrote the earlier file(it looks like uncompiled C++ and jibberished text) when I saved it after completing an entry. This was many months ago. Though the idea of attempting a restore with Ubuntu Remix or other recovery Linux distros is appealing I'm doubtful I'd get far, though it's an SSD not a traditional harddrive and they don't work the same.
Back to the main point though, I suspect the overheating corrupted a prefs file which is causing the glitch I'm seeing, and reloading the OS did not fix it.

External display incorrect resolution when MBP lid is closed

Hi,
I've just bought a 24" Samsung monitor for use with my 2011 MBP. The optimum resolution for the monitor is 1920 x 1080. I ahave it hooked up through a minidisplay to vga adapter. When I have this resolution selected in extended display mode it works fine, however when I close the lid and run the monitor with the same resolution as the main display, the image gets squashed and the screen flickers, I can also see faint lines in the background and the display is not centred, leaving black gaps on either side of the screen.
The frustrating thing is it was originally running fine before I temporarily changed the resolution in display preferences when in closed lid mode. Is there any kind of fix for this?? I know it's not the monitor's fault because it's displaying the correct resolution when in extended desktop and on other systems.
Any help would be greatly appreciated!

What else can I try??
Any bossy third party apps trying to control things?
Run Apple Hardware Test, and/or a trip to the "genius" bar.
No thrid party apps have access to my display prefs as far as I know. And the hardware test did not indicate that anyhting was wrong. I would like to leave the "Genius" bar as a last resort, they weren't much help last time...
Ok so moving the menu bar is allowing me to use the external as native desktop, but this doesn't fix the resolution problem when I close the lid even though the resolution in display prefs is set the same. Is it possible then to tell the mbp not to sleep when I close the lid?? I know you can do this in windows. Please note that I am still using Snow Leopard v10.6.8

I am not able to transfer pictures from my Iphoto file to my external hard drive. When I drag and drop to the external hard drive, I get the universal circle with a line through it.????

For some reason, my computer will not let me drop my pictures from the Iphoto location to my external hard drive.

The drive is formatted for Windows. To write to it from a Mac, you will either have to reformat it or install third-party software to enable writing to an NTFS volume (not recommended.)

Display Popup/message when refresh/close browser window

Hi all,
In normal ABAP programing when we exit from any transaction, a popup display with text "Are you sure to exit". I have some doubt to get this functionality in WDA.
I am calling a popup in WDDOEXIT method of the Comp controller and when I do refresh/close the application, this method will triggered, but it does not opens a popup as the application relaod.
Is there any way to get this functionality?
I have also checked the thread [ABAP WebDynPro Refresh (F5) issue|ABAP WebDynPro Refresh (F5) issue;.

Short answer - no. Only the work proctect functionaltiy that can be used in the portal or the NetWeaver Business Client. By the time WDDOEXIT fires, it is too late to produce any rendering output or stop the browser from closing.

External display jitters, only when I drag a window, or switch apps.
