Anyone found an answer - Dual display stuttering when 1 display turned off

Hello,
I'm having exactly the same problem as described in this thread. Running two displays out of newest Mac Mini (mid 2010 model). Video runs perfectly until I turn off one display, and then the video has a stutter I can't get rid off. Any ideas?
http://discussions.apple.com/thread.jspa?threadID=2144836&tstart=15
Thanks for any help you can provide.

I'm running eyeTV as well, but have noticed the issue on occasion wether it was running or not.
I'll have Snow Leopard up and running soon and be doing a clean install of everything and try to monitor the issue to try to determine what the culprit is.
If you run across anything in testing definitely post and we'll hopefully get it all resolved.
Just tried something which has usually set off the mouse stuttering, simply moving the mouse over towards the right side of the screen, where I have my dock located, the mouse will freeze temporaily, however, eyeTV which was still running, showed no signs of an issue.

Img alt="text" not displayed when images are turned off in Safari

I have tried to search this, but every search has returned too many posts, so I apologize in advance.
Have I made some error or is there an issue with my Safari? For some reason my Safari does not display alt="text" when images are turned off?
This is what is supposed to happen (see http://www.w3schools.com/tags/attimgalt.asp) and it works fine in my other browsers (Opera, FF), but with Safari I get nothing - no image, no alt text, no indiciation that an image is supposed to be in that place. According to w3c, Safari is supposed to be compliant.
There is no problem with the site itself, I am designing the site and test with and without images to see how it degrades. As I said, it works properly in Opera and FF - the alt="text" text is displayed in place of the image - but not in Safari.
Is this just my Safari? How do I fix this if it is?
Is it Safari in general? If so, how do we get it fixed, because this is clearly just not correct?

It's not just you. I see the same thing in my Safari. It appears to be a Safari problem, in which case the best thing to do is submit feedback to Apple's developers via the Mac OS X feedback form. (You will not receive a response, as that page notes, but the feedback will get to the people who can use it.)

TS3700 My ipod stills pauses when the display turns off, even though, my headphones are correctly attached (or flushed)

My ipod stills pauses when the display turns off, even though, my headphones are correctly attached (or flushed)

Does this happen still when you use another set of headphones? Have you check to make sure the headphone jack is clean and clear of debris? If so, the jack may be faulty or damaged meaning you'll need to take or send your iPod in for service/repair.

When display turns off system improperly ejects Western Digital external hard drive. Yosemite 10.10.2

Why does computer improperly eject my Western Digital (My Book for Mac) external hard drive when display turns off. And how do I stop this from happening.
Yosemite 10.10.2
27 inch iMac
3.2 GHz processor
intel core i5

Your External Western Digital usually has Utilities from the company that can be downloaded from their site@http://support.wdc.com/product/download.asp?groupid=133&sid=157&lang=en
run their scan for errors and post back. Also do you have Time Machine always running at time of incident?

Display turns off when i am talking

Display turns off when i am talking (emidiatly) - when conversation is terminated display is working back again - if i plugin headphones evrything work fine
I restored the device twice nothing helps.

The display is supposed to turn off when you hold the phone to your ear (so your ear doesn't touch any controls). If it happens when you are not holding it to your ear this usually means that your case is covering the sensor that turns it off when you hold it to your ear.

Macbook display turns off when booting Snow Leopard DVD

I have mid-2009 Macbook Pro and I hate Mountain Lion. I want to do a clean install of Leopard using the DVD (grey) that came with my computer. I loaned it to a friend recently and he had no issues. But everytime i try to boot from the SL DVD (hold C at startup) it behaves normally, until about the time it would go into the DVD startup screen. At that point the display turns off (not the whole computer, just the display) as if it has gone to sleep. And I can't get it to turn on again. I've also tried booting and holding Option and choosing the DVD as the boot drive. No dice.
Awhile back I created a Lion install DVD. I can boot to it just fine. But i don't want Lion either. Any ideas why this is happening? Thanks!

Press control shift eject, then any key to toggle the display from sleep/wake.

Yoga display turns off after 1 minute

I'm having an annoying problem with my new Yoga related to the display and have not seen any other posts with a similar complaint so perhaps this is a simple fix that I'm just not able to sort out on my own. My display turns off after 1 minute of inactivity. The only means for changing behavior like this that I am aware of is through the Control Panel Power Options. My settings for "turn off the display" are 10 minutes on battery and Never while plugged in (note screen shot attached). Regardless of my settings, the screen turns off after 1 minute. I've changed the settings to multiple configurations and restarted with no change in behavior. Perhaps there's some other settings area, maybe something specific to Lenovo that I'm not aware of (since this is my first Lenovo laptop). Anyone with similar problems or insight?

This may be a Windows 8 issue. I finally fixed this problem by identifying the screen saver as the issue (and I wasn't using a screen saver). Type "lock the computer" into the search box after clicking the search charm, which brings up the screen saver dialog box. Mine was set to 1 minute, though I'd never set it myself. If you can't change it, choose a screen saver and you should be able to do so (and can then switch back to no screen saver). BUT, here's the problem. Other things you install (or settings within things you install) can apparently change and override whatever you type in for the delay time. Try applying your new time and exiting from the dialog box, then open it back up again. I was finding that it kept going back to 1 minute. To reset things so that you can get control again, type "user accounts" into the search box and when the dialog box comes up, choose "Reset Security Policies". Then you can go back to the screen saver dialog and successfully change the delay time.

T42 Display turns off after moving

Hello everybody!
I´ve got a problem with my Thinkpad T42 (2373fwg), XP prof. with the latest updates running. After installing the latest drivers for display (ati) and for "ThinkVantage Active Protection System " the display turns off immediately after moving the Thinkpad. I can turn the display on again only by reboot. The error appears even in a second after reboot, so it doesn´t concern to windows. The system doesn´t crash, it´s only the display. The problem might concern to the shock sensor, but I don´t know how to solve it.
Does anyone of you has an idea?
Thank you and kind regards
Bill

I have a similar problem: T42 (2373-5wg) Screen blanks. At first screen blanking was rare and seemed to happen when moving the pc, but now the screen blanks within 1-3 minutes after turning on the laptop, even if the computer is left untouched after being turned on.
It is not OS related as the blanking appears even when in BIOS setup or booted on a liveOS CD.
I can't tell for sure if the system crashes or not as the display goes blank (doh!), however, I have seen no reports of registered crashes in the visible part of the boot process.
The screen blanking appears quicker (or even instantly) if the computer is warm (e.g. turned off just before being turned on).
Blanking appears simultaneously on the LCD and on any attached external monitor, so I believe this rules out a defective LCD, backlight or inverter board.
I'm thinking it's a failing graphics adapter or system board, or maybe a loose connection that causes a component to overheat and fail. But I don't know which or how to fix it.
It IS out of warranty, of course. Any ideas?
Thanks in advance,
Niels
EDIT: It seems this could be yet another case of badly soldered BGA chips that seems to be troubling the T4x series:

Hello candymerna,
At this point I would recommeng resetting the device if if will not turn on.

W520 - now changes to "projector only" whenever display turns off in power save mode

I have my W520 in a dock with an external monitor. The display is configured to Extend - the external monitor is primary, and the desktop extends onto the W520 screen. I don't have a screen saver. I turn off the display after 30 minutes of inactivity. Until recently both the laptop and monitor screens would turn off after 30 minutes, and then both resume when I moved the mouse or pressed a key.
Recently, the system has started changing to "Projector Only" when the display turns off. After resuming from power save mode, only the external monitor activates, and the W520 screen is disabled. I have to use Fn-F6 to switch back to "Extend" to re-activate the laptop screen.
I have rebooted and re-saved the power plan.
Why has this happened, and how do I fix it?

Hi, timg11
I have a few questions so that I may gain a better grasp of this issue:
1) What is your machine type and model? You can find this information on the bottom of your machine. It should be in format XXXX-XXX.
2) What is your operating system?
3) Does this issue occur is the computer is not in the docking station? (Please try if you haven't already).
Thanks in advance,
Adam

White Stripes/Display Turning Off

Last night I noticed a bunch of white stripes flicker for about a quarter of a second on my display. This happened multiple times. I shut it down with no problems.
Today I had no problems until everything froze. I could move the mouse, but it would not change from a text cursor. I manually shut it down.
I turned it back on, after a few minutes I had the same issue.
I turned it off manually, unplugged the power for about a minute, plugged it back in and turned it on. After a few minutes the white stripes flickered. I decided to back up everything. After about 10 minutes, during the backup process, the screen went black. I could feel that the computer was still on, but the display was black. I manually turned it off.
I have now been on for about 30 minutes with no problems. The computer was very hot when the display went black. Is it possible that this is an overheating problem?
Any suggestions?

The iBook has a seperate display dimming (display turns off) and sleep mode timers. Go into the system preferences>energy saver to set these preferences. When your display turns off you should be able to reawaken it by pressing a key on the keyboard. Turning it off is not the best solution. If the problem happens while you are still using it or it doesn't awaken when you hit a key then you may need to post here again.
