Black screen after resolution change - help me out?
This problem occured when my 4-yr old Lattitude D810 was working normally after not being used for 5 weeks. When coming out of sleep mode, the computer screen went black (truly black, does not appear to be a backlight issue). The screen will turn black on any setting higher than 640x480, 8-bit colors.
Things that have been tried:
1) Changing resolution to a variety of settings (800x600, 1024x768, and higher)
2) Deleting drivers for the monitor and video card and letting windows reinstall them (also updating video drivers)
3) Turning off hardware video acceleration
4) BIOS is up to date
5) Installing windows updates and dell driver updates
Essentially when any video change is made, no matter how minor, the screen will turn black and have to be restarted, but the laptop appears to be functioning normally otherwise. Doing a hard drive wipe and reinstall are out of the question for the time being, and I'm wondering if anyone has a suggestion other than this. Thanks

I have an XPS M1210, which is currently broken due to a failed Nvidia Geforce 7400, but I've had similar problems with my laptop.
From day 1 of purchasing this laptop, if I ever let the computer sleep...shut the lid while it's on....or let it go to stand-by...the screen will 80% of the time NOT come back on and stay black. Although, the system is definitely on (I can hear and see [HDD light] the hard drive working).
Some likely causes:
1). I've heard a rumor that there is a magnetic switch that tells the computer to turn the screen off when shuting the lid (while the computer is on). Thus, not returning to a lit LCD screen upon opening the lid (for some faulty reason).
2). If you right-click your desktop, under properties....choose your Default screen as the LCD, and not both LCD and External. Sometimes the computer will be confused and look for the External monitor first, getting caught in a loop.
3). Hopefully NOT this, but your video card could be slowly failing....as mine did.

I just realized you stated "shuting off video hardware acceleration."
Make SURE this is ON, or you will get 4-8bit graphics.

My Dell D810 laptop screen developed same problem since a month ago, and I also tried all of the above you mentioned.
Whenever the resolution is increased above 640x480, the screen goes black. I even formatted the hard disk and reinstalled the operating system. Did not help.
I can only use this laptop under the low resolution.
Have you fixed yours yet?

I have same problem with my Dell D810. Recently, all of sudden, I was only able to see screen under low resolution VGA mode or under safe mode only.
Whenever the screen resolution was increased, the LCD screen would black out and I would lose control over the screen navigation.
I was able to fix this temporarily.
I deleted all of Dell display driver by
1. uninstalling the display driver. (under control panel, uninstall program. and under device manager, driver uninstall)
2. going to windows directory and deleting the dell display drivers (all of them). If these drives remain in the windows directory, then the windows will reintall them sometime in the future by itself and black screen comes back again.
After deleting the driver files, set windows default display driver to work. Reboot.
Leave it as windows default display driver. Do not reinstall dell drivers (you will get black screen back).
I was able to increase screen resolution to 1024 by 768 pixels under 32-bit color (this appears to be the highest resolution attainable with windows generic driver).
Looks okay for me to do regular work with the laptop again for now.
Problem appears to be the relationship of the dell display driver software and the dell laptop hardware.
This only occured during the last month (been okay all this time for about 4 years).
During my investigation, I even formatted the hard disk and reinstalled the operating system. This did not help.
The black screen was acting up whenever the resolution was increased beyond vga mode.
Deleting the dell driver fixed it for me.
If anyone know of better, permanent solution, please post.
Thanks.
When I reboot the laptop, it tried to reinstall the

I have since gotten my laptop to work by uninstalling the monitor and graphics by going to control panel > system > hardware > device manager on XP and deleting both the Display Adapter for the graphics card and the four devices that are listed under Monitors.
I would then restart the computer, let it automatically reinstall the graphics and monitor drivers, and then go to the resolution settings. If your computer is having the same problem as mine, it will list your monitor as "(Multiple Monitors) on ATI Mobility Radeon", which seems to be related to the problem.
For some reason, my computer had selected the second "monitor" to be my primary monitor, when in fact there was no other monitor connected to it. I switched the selection to pick the first "monitor" and have since been able to change my resolution to normal. Every now and then (once every few months) it will revert back to the black screen and I do this process again.
Sorry if this explanation was what you already did, but it's what worked on mine. Good luck.
