This thread shows the classic symptom: BIOS/POST and the Windows logo appear, then the screen goes black. That pattern most often points to Windows switching to a video mode or driver that the monitor cannot display. already found the trigger (an advanced monitor option was turned off) and and were right to push Safe Mode — good instincts from everyone, and is also right to emphasize remembering the last change.

Practical next steps (without reinstalling):

  • Try the "low-resolution" or "VGA" boot option from the Advanced Boot Options so Windows starts at 640x480. That often gives you enough display to fix settings.
  • From Safe Mode, open Device Manager and check both Monitors and Display Adapters. Re-enable any disabled monitor entry, or uninstall the graphics driver so Windows falls back to the standard VGA driver on reboot. After you have a visible desktop, set a safe resolution and reinstall the correct GPU driver from the vendor.
  • Use System Restore (from Safe Mode) to roll back to a point before the change if one exists.
  • If you have both integrated and discrete video, try the motherboard video output (or a different cable/monitor) to rule out a hardware or input-selection issue.
  • If the screen is black even before the Windows logo, focus on hardware: cable, monitor power, GPU seating, or try the monitor on another machine.

Cautions and follow-up: monitors typically work with generic PnP drivers — the graphics driver is the usual culprit. Reinstalling Windows fixes the symptom but is rarely necessary; keep a restore point before experimenting. If you want, report the exact OS and GPU model and the precise wording of the option you disabled for more targeted steps.

see if you can go to safe mode and set correct setting .
get to safe mode by hitting f8 on boot up ,start hitting it as soon as you start computer and keep hitting it until you get to screen to chose safe mode .then arrow up to the top to chose safe mode .

Thanks for the quick reply, I can start in safe mode, but as soon as it gets passed that, I dont see anything on the monitor, so I cant go in and change any settings back.

richhar, please boot your system and keep tapping F8 for advance boot options. And select Disable Automatically Restart option. If there is any error (blue screen or something) .. please let us know..

Now that you are up and running you have to remember what is it that you did the last time to cause this black screen

looks to me like they disabled this device , in the monitor advanced settings ,no wonder it caused a black screen , right click on your desktop ,go properties /settings/advanced /monitor /properties .disable this device .my thought anyway ,if it was that would be a no-no

yes you are right, thats exactly what I did. I was trying anything because my screen image was massive and I couldnt choose another resolution. I am trying to fine the driver for my monitor or video card, no luck at the moment.
Cheers for the advice.

thought so ,you don't need or shouldn't need drivers for the monitor .as for video drivers ,i use Everest to show me what stuff is built into my computer [and others as i fix and reload a lot of computer .]Everest can be found on www.filehippo.com, middle of the page near the bottom in the benchmark section
