Computor doesn't pickup the monitor nothing on the screen

If the monitor displays POST messages as it boots, then your monitor is still working. It would appear that either your video card or your monitor settings need fixing. Try booting Windows in SAFE MODE and go to Control Panel. Select Display Settings and uninstall the existing driver for your video card.
Reboot your machine. Windows should detect your video card and install its proper drivers. If you've gotten this far, your monitor is working.
Failing the above, reboot in SAFE MODE again and this time uninstall your monitor. Try rebooting again and Windows should again detect, configure and install your monitor appropriately.
Good luck!

Screen will not display

Have you ensured that your display card driver AND correct monitor driver is installed. This is to make sure that your display card only generates signals that your Acer monitor is capable of handling. If you do not have the driver CD for your monitor you can download the software from The problem is most likely that your display card is generating a refresh rate which your monitor cant handle. Go to your display properties and lower the refresh rate of your display card and see if this solves the problem.
Best wishes,

"Input Not Supported" message on monitor at boot

Sounds to me like the input has gone out of the boundaries the monitor supports. IE the refresh rate is too high frequency (normally 60 to 72 Hertz for LCD's) or the screen resolution has been set too high.

Go into safe mode and set it back to 1024 X 768 at a frequency of 60 Hz, once back into windows proper you can try higher resolutions and change your refresh, if the screen goes black or displays a message "Out of Bounds" or similar it should revert after 15 seconds if left alone.

Have fun

Vison Monitor ( device installer error)

First you need to uninstall the driver for your old monitor. Then install the driver for the new monitor. With both drivers installed your computer is confused and shows the conflict as an error message. Hope this helps.

I tried both suggestions above and neither worked. 1) Hitting the monitor buttons as stated only got me a "digital" message and then the monitor went black as usual. Never got to any menu options. 2) Going into Safe Mode and changing the monitor settings or downloading/installing the correct driver didn't stick once you went back to the normal startup.

I didn't have another monitor handy to swap out so I had to be a little more creative. The only solution that worked for me is re-booting (F8 during startup) into the mode "Enable VGA Mode". This allowed me to go into the normal desktop with a screen resolution of 800x600. I went online, found the driver, downloaded it to the desktop. Deleted the video driver (Device Manager), installed the downloaded version, rebooted problems.
I have Windows XP. Hope I've helped someone today. :)
