External monitor goes blank

The backlight went out on my Toshiba laptop so I hooked up a new(er) flat screen monitor to it. The Windows XP startup windows _begins_ but never gets _to_ my desktop. Windows XP startup runs for about 20 seconds and then the monitor reads 'no signal.'
I simply want to access information (files, folders or photos) on the Toshiba before I sent it to laptop paradise forever.

Hi
Usually you should be able to switch to external monitor using the key combination FN + F5.
I think this key combination would not work in safe mode since safe mode loads only some essential system processes.
So if you are able to boot the Windows OS in normal mode then check FN + F5
You could also try to change the display settings in graphic display properties -> last tab Settings (to get the display properties click right on desktop and choose Properties )

External monitor going blank!

Hello,
I have a exrernal Dell 24' monitor that has been working 100% ok for years on my macbook now am running 10.7.2.
I use the mac in clam mode and using the Dell as the main monitor.
Today I have a problem as after around 10mins of uses the monitor went to sleep! pluging the monitor in to other devices helped to provide its fine.
I rebooted the macbook and still the monitor would not come on!
I done the Shift + Control and power, Command + Option + R+P and the booted in to safe mode and this restored the display :-)
But it kepts on happing every few hours and even sometime the display will come it by its self!
Are odd!
Please can someone help?

If you have another computer or device that could you attach to the monitor to check if it does it over multiple devices?
Also do you have another external monitor or projector to hook up and see if the same thing happens there?
Rule out if it's the MB or if it's the monitor. If you're still under AppleCare, or even if you're not, and are unable to do the above then I would suggest getting it taken in. Schedule a Genius bar appointment to get it looked at.

Dual monitor (w/laptop): external monitor is blank.

Hi! just installed arch for the first time a day ago. Right now what I'm working on is on getting my second monitor running (mostly for development purposes... and movies ^__^).
I'm using Arch64 with the open ATI driver and KDE. Whenever I connect the external monitor, the monitor seems to detect a connection occurred (the "check video cable" message disappears when I connect it and comes back when I disconnect it), and so does KDE. When I open my display settings, it tells me a new monitor was connected and asks me if I want to configure it.
Then I choose to configure and use the two monitors giving the following screens (right now I'm at college testing with monitors in there, thus the low resolution, but behavior seems to be exactly the same):
(EDIT: resized. In case of wishing to read full images, just take the "resized/" out of the URI)
However pretty the full screenshot looks like (... I just mean that even if it looks like the second monitor is working), the monitor remains blank.
Using arandr (xrandr's gui), it is exactly the same result. I might be doing something wrong (almost certainly I am ) (EDIT: decided it was a good idea to show what I did with xrandr).
In /home/<myuser>/.xinitrc my file looks like this:
#!/bin/sh
# ~/.xinitrc
# Executed by startx (run your window manager from here)
xrandr --output VGA-0 --mode 1440x900 --pos 1600x0 --rotate normal --output LVDS --mode 1600x900 --pos 0x0 --rotate normal --output HDMI-0 --off
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
exec ck-launch-session startkde
# exec gnome-session
# exec startkde
# exec startxfce4
# ...or the Window Manager of your choice
The laptop's model is Toshiba Satellite L775d. I'm not sure what other information should be required in this situation, but I will be loving to give anything that isn't compromising
Thank you!
(PS: so far Arch has treated me nicely let's see for how long)

I wondered the same. I initially only used KDE for it (that's how it worked in other distros, but I'm guessing Fedora and Kubuntu have way more stuff on top). I moved to xrandr later after searching for options and I did select "Ignore" when KDE asked me to configure and just went ahead with xrandr. The same still happens.
Thanks, I hope I gave the right information.
EDIT: Adding some extra information. I tried rebooting with the CRT cable connected. When the kernel initiated its loading, the messages only appeared on the external monitor. It was afterwards (it was pretty quick, but I will assume it was when radeon's modeset hit) that the external monitor went blank again and, in that situation, the laptop's monitor went blank (so none of the two monitors worked... and I was so hopeful!)

IBM Thinkpad Monitor goes blank after a few miniutes

Hi,
I have aT43p with an ATI Mobility FireGL V3200 running XP Sp2. For the past couple of weeks the screen goes blank (Black) after several minutes. I can use the Fn-F7 to toggle the monitor between LCD and external monitor (which is not attached) and back to LCD (or dual display) and the LCD works again!, but alas only for several more moments and then it goes blank again and I have to re-toggle. I find that if I run on only battery power I get several extra minutes before Blacks-Ville. The same effect can be achieved by putting her to sleep and then waking her.
I should mention that there is a slight pink tinge to the display during the initial splash screen (while the option to enter the Bios via blue Access IBM button), but this goes completely for subsequent screen displays.
I can connect across the LAN using VNC and can see windows (as one would expect).
I have gone to the support area and downloaded all drivers and reinstalled to no avail. I have also checked the Monitor connections, but there is no obvious loose connection. I have also run a in-depth virus analysis (using ESET NOD) and an Adaware sweep, again with no positive result. I have also gone into MSCONFIG, disabled as much as I can and I have also rolled back using System Restore to a time before the issue presented.
Nothing that I have done to date has made the slightest difference.
The screen Blacks even if I go straight to Bios which inclines me to think that the problem lies outside of Windows.
If anybody has any ideas or suggestions I would really appreciate it.
Thanks
Dave

Hello ddempsey,
I can confirm all your problems (except the "slight pink tinge"- sure it is not
a reflection or so?), I've got them on my a21p since a couple of years as well.
I am using an external monitor after I tried all software possibilties and was
fed up with the toggling. colours are still excellent, I contradict a dying
as such, a digital display is either on or off, not fading away.
in desperation I replaced the inverter card (part number 12P3053) as a
last resort but without any success.
so I was happy to find one with exact the same problem and I hope
by jumping on your train that someone comes up with a solution.
have you tried this:
if you do not boot windows, leaving a plain start screen
either by pressing pause or later f8 the display shuts down
in the same way, thereby proving that the problem
is beyond an explanation due to a higher resolution task.
this arouses a suspicion whether the ATi Rage Mobility graphic card
(messing up in all brands of notebooks - see copious complains in the www)
might be the cause. unfortunately ATI been bought by AMD
but the support of its successor for old cards is a disgrace compared
what Lenovo still delivering for ancient IBM users!
regardsDamian

HT3131 Clamshell mode not working even after powering off and reconnecting display; external monitor goes black anyway

After connecting an external monitor (non-Mac) to my MacBook (Mac OSX 10.6.6) w/proper adaptor, setting up to use clamshell mode as per manual, the external still goes black even after putting MacBook to sleep, disconnecting and reconnecting external and powering up again as suggested in Support. Displays are set to Mirror. Also, when I open Displays in System preferences, 2 different windows for Resolution settings appear. Where have I gone wrong? This monitor (Viewsonic) came with it's own software for setup on a Windows PC, but of course it is not being used on the MacBook.
Any help would be appreciated!

Hi Mike,
Yes I followed all the procedueres....except for waking the computer using a keyboard click. For obvious reasons one is just inclined to open the top of the MacBook to wake it when the external goes dark...I did that twice, until I realized that very last step was needed to 'wake' it. It worked. Something so simple, easy to overlook I guess.
I did leave the monitors mirrored, fyi, if I don't then all I can access from the external are the resolution settings. This Viewsonic comes pre-loaded with Windows software of it's own and doesn't quite behanve the way my previous external did, but I got it figured out.
Thanks for your response, tho!

Pavilion f1703 monitor goes blank 2 seconds after start-up

When the computer is turned on, the monitor only functions for a couple of seconds before it goes blank..power light shows it to be working.
If I turn the monitor off at the front power switch, and turn it back on, the same thing happens..2 seconds of normal then blank.
In the couple of days leading up to this, the screen had a slight "flicker" effect going on.
All ideas greatly accepted!!

I am having the identical problem. I hooked this monitor that a friend gave me and it worked great for several days. There were no flickerings or any indications of a looming problem. Then it started going blank after 2 secs and continues to do that. I did see a warning about the "power saver", or something like that, was in operation. Unfortunately, I can't get it to stay on long enough to go into the menue and see if there is anything I can change there. Any help would be appreciated.

Laptop monitor goes blank

Can Flash cause a laptop monitor and the attached monitor to go blank when playing a game on facebook using firefox latest version? I have this version installed 11.7.700.225

I saw another thread in which people were wondering why you'd want to run a machine with a lid closed. For one thing, the external monitor resolution is much better w the lid down. It appears you have to have the laptop plugged in in order to get the external screen to stay live when you close the lid. This is kind of a pain because one of my desks is upstairs and one is down and sometimes I just want to run upstairs and work for 1-2 hours without bothering with the power cord, etc.

HP Omni 220-1050xt Monitor goes blank at random times and will not light up.

Recently my computer screen starting going blank without any warning. One minute it is fine and I am working away, then the screen turns black and no key sequence will bring it back. I have selected a power scheme that has never, never, never set in the categories. I also sent my screen saver to None. I took it to Staples to run a diagnostic which responded with no errors. Within 15 minutes of running, the screen was blank and the computer was unresponsive.

Hello @jlh41,
I understand that you are experiencing an issue where your HP Omni 220-1050xt Monitor is going blank without warning. I am providing you with some steps you can try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
Step 6. Try different cables between your computer and monitor.
If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. Please call our technical support at 800-474-6836.

Premiere Pro 5.5 program monitor goes blank, please help!

I started a super simple brand new project in Premiere Pro 5.5, importing only simple, small resolution png files (to create an animation), and my program monitor goes completely blank. This started happening right when I updated the driver for my video card. I run a Windows 7 64-bit machine, with NVidia Quadro 2000, driver updated (333.11), source footage is png files, my OS is up to date, I use just a single monitor, there are no error messages at all, when I try to scrub, my program monitor stops working (it shows a still image), then suddenly it goes completely black! I have no third party effects, plug-ins or hardware installed. And yes, my Mercury Playback Engine GPU Acceleration is good. I am completely stumped since the project is barely started. Does anyone have any ideas?!

Monitor goes blank randomly

I have a MacBook Pro (Retina, 13-inch, Late 2013) and for whatever reason my monitor will go blank and everything keeps working such as sound, etc. It comes back and it happens a few times a day. This occurs with two different brands monitors although both are connect via DisplayPort to HDMI and I've also done HDMI to HDMI. I have occasionally connected an external monitor via DisplayPort to HD15 and no blank outs.
The only common part is my MBP and the monitor connecting via HDMI. Different cables, different brand monitors, etc. I am running 10.10 and this has happened with for quiet a while from 10.8 until now.

I am using the Thunderbolt display on a PC with the ASUS P8Z77-V Thunderbolt enabled mother board. I have a dual display setup with and smaller VGA monitor.
The Thunderbolt display blacks out randomly. Sometimes I can use the resolution tool from my secondary display, reset the resolution down and the Thunderbolt comes back on. Other tiomes that doesn't work and I have to re-boot. This happens several times aq day. I thought it might be the motehr board, as this is fairly new technology in the PC/Windows world.
Next time it happens, I'll see if I can use the flashlight trick - maybe get it repaired at Apple.
Thanks

External monitor goes black when macbook pro has magsafe connected

Hi,
I have bought an external monitor about 1 week ago, and I have it connected with a minidisplay to dvi cable, and a dvi cable to the monitor.
It was working OK -well, it had some sudden flash to black screen that lasted about 1 second, but nothing else- until thir morning when it just started showing a black screen. Mac OS sees the monitor, and I can move windows over there, etc. It's "alive". But I only see a black screen on the monitor.
I tested with other computer, and it works OK. The cables work too.
What I discovered is that if I unplug the power adaptor from the MBP the monitor screen shows correctly.
It works OK only if the magsafe adaptor is unplugged from the MBP, it doesn't care if the magsafe adaptor is plugged to the power or not; only if it's connected to the mac book pro.
It seems like some magnet stuff is making a mess there. What could it be? I can't work on the monitor only in battery power...
I tried resetting nvram and the other stuffs that I found here, but nothing works.
Thanks!

Start up has pink vertical lines then monitor goes blank on iMac

I was working on my computer when all of a sudden the screen went grey with 5 vertical pink lines appeared. I have switched the monitor off, but now it starts up with the pink lines then goes to a blank screen, what is the problem?

Sounds like a hardware problem ..
You can run the Apple Hardware Test
Or take your Mac to an Apple Store or Apple certitied repair provider listed here.

Program monitor goes blank when editing certain clips

A few days ago a 2 new problems occurred.
1.
The project I have is sett to 720, 24 fps.
The clips I use is from 5D MK3, shot in 720, 50fps.
Some of the clips I made duplicates of, and interpreted to 24fps for a slomo effect.
The 24fps clips works fine on the timeline. But the one that still has 50fps will go black in the program monitor when I try to edit them on the timeline.
It doesnt matter what I do, ripple edit or just shorten, still gets black. If I drag the marker over tha clips it shows fine though, but when editingt hem, just black.
2.
The second problem is regarding the very last clip in the timeline.
The last frame, orjust some visual error after the last frame, now has the right part of the program monitor screwed up. A part of the screen is black.
All this started like 2 days ago, after I upgraded my 2xSingle license to full CC. I had PS and PPro before.
Whats going on?
Some facts:
- Premiere Pro CC 7.1.0 (141) - All updated
- Win 7 64bit (all updated as of 2013-11-30)
- 64 GB ram
- Clips from Canon 5D MK3, 720, 50fps, IPS codec
- No other software running, restarted several times
- Geforce 480GTX, Asus P9X79, Intel Core i7 3820 3.6 GHz, Corsair 32GB (4x8192MB) CL10 1866Mhz
- GeForce Drivers 331.82
- Never had this problem before
- Mercury Playback Engine GPU Enabled (disabled doesnt solve the problem)
Please Advice

2 screenshots

As I wrote, " I can drag the ends of the in/out points, BUT I cant drag the selected area in the source monitor"
Again, the source monitor was just a comparrison, to show that this wasnt a problem only with the program monitor. I posted the image since you didnt understand what I meant.
There are apparent issues with inserting theese clips on the timeline or editing them. I'm sorry if my bad english messes this up
I guess you'll have to include all the info I have written to get a grip of the situation, so I will try to clarify again for you, if you think it will help
- The project I have is sett to 720, 24 fps.
- The clips I use are from 5D MK3, shot in 720, 50fps.
- Some of the clips I interpreted to 24fps for a slomo effect.
- I have QT installed
- All drivers updated
- The interpreted 24fps clips works fine on the timeline.
- But the one that still has 50fps will go black in the program monitor when I try to edit them on the timeline.
- It doesnt matter what I do, ripple edit or just shortens/makes longer, it still gets black.
- If I just drag the marker over the clips in the timeline it looks fine.
- If I interpret to 1-48fps, it works fine. Only 49-50 fps screws it up
- Some problems occur in the source monitor. I CANT drag the full grey selection with the handle in the middle I made with in/out points, as shown in the picture
- I tried to make a new project, same problems.
- Everything worked fine a cople of days ago
I hope this makes it easier to locate the issue.
Thanks

Second monitor goes "blank" when first monitor goes full screen in Mtn Lion.

Hello Apple community. I am using two monitors and when I put a program like iTunes in fullscreen mode (with the arrow symbol in top right) the second monitor displays that grey patchwork and I can't move windows over there.
My question: Is there any setting to change this (so I could have one screen in fullscreen mode and the other screen on the desktop) or is this just the way it is?
Any info would much appreciated!
Thanks

It's just the way it is.
BetterTouchTool (free app, in the app store) has a little feature that resizes your windows to full size when you drag them near the top edge and returns them to the previous size when you drag them down again. I find this useful when using two monitors (saves you having to resize them manually).
