Display divided in 4 iqual size and background

Right click on an empty area on the desktop, select "Properties" from the menu and select the 'Settings' tab. Under the 'Display' heading, select your new screen from the drop down menu and click Apply and OK and see if this helps..

Hello gkirindongo,

Do you mean the wallpaper of the desktop is divided into 4 equal parts, or do you mean the whole desktop is divided into 4 equal parts? (are there 4 "start", 4 "recyle paper", 4 "My Copmpure, 4 mouses cursors?...)

In the desktop properties , settings tab , you can clone the desktop to the other screen or make it extend to the other screen or make one or the other the primary , so you should check that setting in there to see if thats the setting problem thats giving you that kind of display

1. Click Start, Settings, Control Panel, and double-click Display icon.
2. In the Display properties window click the Settings tab.
3. In Settings tab under the Display click the down arrow and select the secondary display connected to your computer.
4. Once selected check the Extend my Windows desktop onto this monitor option.

Check the Horizontal Adress Range (AP) --> Register it must initialized with the value of 0x50

Hope this helps

Sir,

go to the menu and click the Factory default settings.

Uninstall the display drivers and reboot the machine, if the problem is resolved then re-install the driver again
Problem should be solved

hope this works for you kind regards

I would check the cable and connector pins first.
Then I would suspect there's a problem with the video signal board inside the monitor.

It could be the LCD panel controls, too. That would make the unit beyond economical repair unless you got a used one.
