Having problems with your Computer Monitors ?

I changed resolution from 640x480 to 1024x768 and all i get now is a blank screen. cannot get back in to change resolution back to 640x480


Answers :

Reboot the computer in "safe mode with networking" by rebooting the machine and during the manufactures name screen, tap the F8 key and you will see the muli-boot menu come up. Safe mode usually loads a resolution the video card and monitor agree on. You may have corrupt video drivers that give the black screen. While in safe mode, go online to windows update and let it scan your system, choose custom installation and look for the optional updates, these will be the hardware drivers you need to update your system. Check them all if you like and let windows install them automatically. Once done reboot normally and see if that clears the problem.

Hi, I got a serious problem with my PC. The PC was working as "normal", but the monitor display was not "perfect" :-). So I went to control panel->display->setting->advanced->monitor. I cannot remember what exactly I have done, maybe I disabled the only monitor, which is the "default monitor". Then the computer automatically re-started. When the window come-up, there is no display on the screen. I think the computer was started correctly, but just no display. By now every time when the computer
