Screen Sharing: Dual Display to Single Display, Goes Blank

Hi everyone,
I have an issue seeing dual displays properly on another computer with the Apple Screen Sharing app.
From one computer, with Mac OS X 10.5.8 installed, I'm connecting my other computer elsewhere, which is running 10.6.3. I'm connecting by setting up an SSH tunnel, forwarding the VNC ports, if that's relevant.
The computer I'm connecting to is a Mac mini (early 2009), with dual displays. When I connect initially, I can see both displays. Which is fine, but they're a little small. When I try to select one display only (through the View menu), the screen is black. There's still a cursor, but it's hovering around in black space.
Can anyone help with what might be causing this? I'd be happy to provide more details of connections/hardware if that would be useful.
Thank you,
W.

Does anyone have any thoughts about this?

Display goes blank and computer locks up

I have the P205D-S7802. When we close the lid, a password is required when it's opened. It usually comes right awake for us, but after it's been awake for awhile, the screen will go blank and the computer will lock up. We have to power it down the hard way and power it back on. It's usually okay until the lid gets closed and opened the next time...
I've also tried to set a screen saver several times, but it never seems to take effect.
Help.
Please.
Solved!

Right after starting up display goes blank and shuts down?

Right after starting up display goes blank and shuts down?
Any ideas I can't get it started. Thought I would ask for help before making a genius appt.

Thanks that was very helpful info. I was able to boot into the recovery disk partition and run some basic HD tests and it found no issues. Then I booted into the hardware test and it found no issues. After these tests it still failed to boot into Mavericks. I'm guessing its a software issue and I can not find the original computer disk. I have a time machine backup from 2 months ago and I could use the disk utility on the recovery sector to launch it but I want to wait and see if I can boot from a software DVD first. If I can repair the current OS that is my best option.
Thanks.

Acroread full screen problem - dual display on Linux machine

Hi:
I am running Linux Fedora core 15 on an HP laptop that I use for presentations. I have dual displays set up and run my presentation software (opera and acroreader) in the external monitor in full screen mode. This works fine for opera, but when I try to use acroreader, it only appears on the laptop's built in monitor when in full screen mode. Any suggestions on how to get it on the external display?
Thanks.

When you normally play iTunes on a secondary monitor (23" Cinema on the side) and then disconnect to go mobile, there's a problem - can't get video window to show up anywhere without changing preferences to have video display in iTunes window or art window. Disabling spaces, checking display, "detect displays", nothing else works.

Second screen blacked out when full screen with dual displays

I have a MacBook Pro connected to an LCD display. I use both screens. When working from home I'd like to have my local machine showing on the LCD monitor and my work machine showing in the MBP screen. I can do this, however I can't have the work machine in full screen mode because ARD blacks out my main LCD monitor. This frankly drives me nuts as there doesn't appear to be a preference within ARD to change this.
iTunes does the same thing. If I want to watch a video full screen in one monitor it blacks out the other. C'mon Apple, Quicktime doesn't do this and has a preferences tab just for display settings!
Does someone have a suggestion, work around, or want to point me to what I might be missing to solve this issue?

I understand what you are doing, but when you are running as full-screen the second display is blacked out because your making your station only the target at that moment. You are telling ARD that you want nothing to do with your Admin station. Also because the target doesn't have a second screen, your is blank. This avoids any confusion as to what screen belongs to what machine. ARD is working as it was designed to.
iTunes does the same thing to hid extra screens that are not part of the presentation so they don't detract from the show.
With your Observe or Control in Windowed mode, make the window of you client to fill the display as much as possible. This is the best you can do. Besides, when you are Controlling a client in Full-Screen, you can't move files and such with drag-n-drop. So if you want to work on both at the same time, you need to stay in windowed mode.

Using Boot Camp to install Windows XP: problems with display going blank

I have a new Mac mini (early 2009) connected to an older NEC MultiSync LCD (VGA only) display through a KVM.
I initially used the Apple Mini DisplayPort to VGA adapter to make the display connection.
All worked fine with Mac OS X, but when I attempted to use Boot Camp to install Windows XP (Home), the display would go blank with the display saying "no signal" at some point during the install and I couldn't get the mini's display back without power cycling the mini. Numerous attempts at removing the Boot Camp partition, re-partitioning, and retrying resulted in nothing but frustration. I typically had to force the mini to boot from the OS X install DVD or Mac partition to make the mini usable again.
I have used my LCD display and KVM combination with a variety of computers running a variety of operating systems, including older Mac minis running both Mac OS X and XP, with no problems. And I intend to keep using it, so I wasn't going to assume the problem was there!
After noting that Apple had already released a [firmware update|http://support.apple.com/downloads/Mini_DisplayPort_to_VGA_FirmwareUpdate] for this adapter to address "[possible intermittent flickering and compatibility issues|http://support.apple.com/kb/HT3492]", I double checked that it was up to date--and it was. But, it made me suspicious that this adapter might have some more problems and be the source of the troubles I was experiencing.
So, I got an Apple Mini-DVI to VGA adapter and tried that.
No more display problems! Everything works fine with Mac OS X. Windows XP installed without so much as a flicker, and it works smoothly with my setup.
I'm curious if I'm the only one who was affected by this problem?

Restart your Mac while holding down the Alt/Option-key until you get to the Boot Selection Screen.
Choose to boot OSX.
Use the BootCamp Assistant to remove the Windows partition.
Go to System Preferences then Startup Volume and rest the default to be your OSX volume.
Reboot your Mac again.
Follow the instructions from here http://support.apple.com/kb/TS3173 and use the BootCamp Assistant again to install Windows 7

Mac Pro display going blank when opening Pages.

I have a Early 2008 MacPro 3,1, 2 x 2.8 GHz Quad-Core Intel Xeon, 2GB 800 MHz DDR2 FB-DIMM / MAC OS X LION Version 10.7.4
Graphics ATI Radeon HD 2600 XT 256 MB.
When I open Pages, the screen goes black with horizontally moving thin white stripes - Then the desktop appears again for a second, then it goes black again. This happen on and off for about 5 minutes and then goes away. It also goes away when I close Pages, if I can do that quickly when the screen appears again for a second. I have Pages '09 Version 4.0.3 (766). This has also happened since the first year I bought the computer. Apple said it may have been the cable - Their phone support was never able to fix it. I just recently found this was related to Pages. Please help if you can.

Try doing an SMC reset.
If your Macbook has a removable battery remove it and disconnect the Magsafe power adapter. Now hold the power button on for about 5 seconds. Then put the battery back in, attach the power adapter and power it back on and see if the problem goes away.
If your battery is NOT removable, to do an SMC reset hold down the Command + Option + Shift + Power buttons all at the same time. You won't get any indication that anything has happened but this also resets the SMC on those systems that don't have a removable battery.
Hope this helps!

Screen flickers for a few seconds then goes blank

I have been reading these threads trying to find someone having my problem, but the popular issue seems to be with lines on the screen. Mine just goes completely blank a few seconds after start up. Any words of wisdom?

Unfortunately, the internal power supply within the AirPort Express has likely failed.
As a last resort, try a Factory Default Reset as follows:
Power off the AirPort Expess for a few minutes
Hold in the reset button, and keep holding for an additional 9-10 seconds while you simultaneously plug the Express back into power
Release the reset button and allow a full minute for the Express to restart
At this point, if the Express is operational, it will display a slow, blinking amber light.
If it doesn't....then it is time to replace the AirPort Express.

On my iPod touch, (4th gen, iOS 6.1.5) it won't let me get into my purchase history. It says loading in the middle of the screen for like 3 seconds then just goes blank. What is the solution to this problem?

It won't work because I really want to get flappy bird back!!

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>iTunes and App Store and sign out and sign back in
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

My Nokia 9300 display goes white

After I dropped my NOKIA 9300 on road, both the displays goes blank (white) somebody please help me, what has happened with my phone?

Chances are the mainboard was damaged in the drop if both displays are dead. Sadly due to the old age of that model there's probably nothing that can be done to fix it as parts are likely no longer available.
You could try contacting a Nokia care centre but don't get your hopes up. www.nokia.com/repair

Imac 21.5 (ver 10.6.8) Display flickers and it goes blank

Display flickers and its brightness automatically increases and decreases intermittently. After some time the Display goes blank and it doesn't appear even after pressing the power button or restarting the PC. At times it does appear after pressing the power button frequently or if the PC is left ON for some time. I am using software ver 10.6.8. Want to whether this problem will be resolved after upgrading it to Mavericks. But I am worried that during the downloading if the display goes off and if I have to restart the PC then I will have to start the downloading from the beginning. Please suggest.

If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US.

Screen sharing a user account

Is there a way to use screen sharing to display a particular user account on the host computer? I use a Mac Mini as an HTPC with Plex running all the time on an account aptly named "Plex", but I'd like to be able to use screen sharing on my Macbook Pro to view and manage another account on the Mac Mini while Plex is still running and displayed on my TV. Basically, I want to be able to manage the computer without disrupting the entertainment! Any way to do it?

Not really.
There is a hack using the "Vine Server" VNC server.
<http://www.versiontracker.com/dyn/moreinfo/macosx/16699>
You enable Mac OS X "Fast User Switching" in System Preferences -> Accounts.
You login to the account you want to Screen Share, and start Vine Server, using a port such as 5901.
You now use Fast User Switching so you can bring up your Plex account. Do what you want/need so it is operating normally.
Now from your MacBook Pro, you connect to the Vine Server. Finder -> Go -> Connect to server -> vnc://mac.mini.address:5901
You should now be talking to the alternate account.
Your mileage may vary on how well this works.

MacBook Air 13" Mid 2013 Display go Blank

I have set my MacBook Air Energy Saver setting to its default settings...
When its go on standby mode then i click/swipe on trackpad immidiately , Display going blank but keyboard Is working.
And if i wait 10 to 15 sec after standby then there is no issue.
Please Advice me how to fix it

If you take a look at these (very lengthy) threads, you will see this is a widely reported problem, for which Apple have yet to produce a solution. It is said that they are working on a firmware update that will address it but this has been talked about for a long time and still no update.
https://discussions.apple.com/thread/5118135?start=0&tstart=0
https://discussions.apple.com/thread/5475679?start=0&tstart=0
https://discussions.apple.com/thread/5495588?start=0&tstart=0
The current "solution" (which is not a solution) given by Apple is to set sleep mode to 'never', or to wait a few secconds after sleep before waking the MBA, or install the free App 'Caffeine" which allows you to manually activate sleep and wake.
Some persons have claimed a "bare metal restore" of the operating system resolved the problem but others have tried this without success.

HDMI out goes blank

I purchased a Samsung commercial signage TV for running videos and powerpoint shows in my tradeshow booth. When I connect my HP ProBook 4540 laptop via HDMI to this TV, everything looks perfect but only for about 10-20 seconds then the display goes blank and I have disconnect the HDMI cable to get my laptop screen to come back on. I can reconnect the cable and again the TV pops on, looks perfect, and blanks out after 10-20 seconds. I have tried mutiple HDMI cables, checked and rechecked the port settings. The resolution comes up correctly every time (1080x1920) and I've also verified that the TV works perfectly with other computers (i.e. my Win7 desktop). Why would my laptop cut signal to the HDMI port? Hauling my desktop around to trade shows is not an option! ThanksBelldog Oh, BTW. It's AMD Radeon graphics.....

Hey Gmack07,
Thanks for the question. I understand that you are experiencing issues with mirroring your iPad via HDMI. What adapter are you using to accomplish this?
For Apple-branded adapters, see the following resource for troubleshooting information:
About Apple Digital AV Adapters for iPhone, iPad, and iPod touch - Apple Support
http://support.apple.com/en-us/HT202044
Troubleshooting
If you encounter an issue using the Apple Digital AV Adapter or VGA Adapter:
Disconnect and reconnect the adapter from the iOS device and display.
Connect directly to the TV, projector, or external display using a known-good VGA or HDMI cable.
Remove any VGA or HDMI extension cables or converters.
Note that accessories that convert a VGA or HDMI signal to other video formats (DVI, Composite, Component) are not supported.
Ensure that you are using the latest version of iOS. Some Apple Digital AV Adapters require iOS 5.1 or later.
When using an Apple Digital AV Adapter manufactured before early 2012 with iPad (3rd generation), you may see the "This accessory is not supported" alert. Dismissing the alert will allow you to use the adapter.
For optimal performance, you may need to adjust the video resolution or settings for your display. If your display offers an "auto detect" or "factory default" setting, you may be able to use these options to optimize video resolution and display.
Thanks,
Matt M.
