Acer x223w issues- freezes

The backlight controller has failed. It can be repaired or replaced.

The VGA section of the Monitor is totally separate circuit than that used by the DVI circuit. Either or will do an automatic switch to what ever circuit communicates via the proper attachment (VG or DVI cable). AS long as the VGA Drivers are up-to-date the operating system should recognize the Video signal. Check the DEVICES and look for Video. Your Monitor should show up if the connection is proper, and if not there, you may have a bad Video Cord.

The white connector is to connect the monitor digitally. The blue connector is to connect via analog.

try changing video cable

You need to change the monitor type. If you open the display settings and then setting tab-advanced-monitor you see a properties button. Click that and then the driver tab on the new window. What you need to do is go to Acers website und get the "INF" or driver file for your monitor. download and save this file. Then go back to the drivers window and click the reinstall drivers button and then point it towards the file you downloaded. This file lets windows know what settings the monitor can use. After that is installed and you go back to the settings window you should find that the allowed display resolutions have changed. You should be able to change it to one the monitor displays properly now.

probably needs new voltage regulator for backlight. it would probably be cheaper to just buy a new monitor

is your lcd has a dvi port? aside from vga? and also is your video card has a dvi port? if all these questions meet, first uninstall the driver of your video card. Then, you need to switch your cable, in order to do this, you must place the one end of your cable to the dvi port of the cpu and the other end to your lcd dvi port. and reinstall the driver again of your video card. see if it works. because there is a certain problem that vga port configuration differs from the
dvi port. that's why when playing games, especially online games. sometimes your system will get corrupted.

Good luck! have a nice day

Hi..there,
If you wanted to be crystal clear... Try using a DVI cable if your monitor got these function. Happy Holidays!

Unrelated to monitor, you have a hard drive problem or you have a flash or a floppy drive plugged in and it is tryint to boot off one of them

Hi...there,
It's seems you need to reset your WB (white blance). Open your on screen display and look for WB settings... Good lucks!
