dell external monitor connected to desktop - used to extend desktop screen. however, the screen goes black after about three seconds. i'll press the power button (the green-backlit power button turns from green to orange) and turn it on again, and the screen comes on for a couple seconds and goes black again.

i am not able to tear the thing apart and look at lamps and transistors or anything like that. any ideas as to what is going on?

Likely something has gone bad on the inside of this system. This solution may sound stupid and you might have already tried it- but ensure that the video cable is plugged in properly and make sure that Windows dual display is set up correctly. If it still doesn't work after that, I would say that your monitor is dead.

Also check the wattage of your PSU, maybe it can't supply much for (dual-screen). Maybe it's busted/overheated.

SOLUTION FOUND

Hi folks,

I had this problem with my Videosonic VE170b monitor: after boot, monitor comes on for just about 1-2 seconds then goes

to black.

Hitting one of the buttons on the monitor (I think auto-adjust) would bring the monitor back again, but for only the same 1-2

seconds. Repeat hitting the monitor button would again bring it back, but only for 1-2 seconds.

SOLUTION: Mine was solved by changing the display color quality from high (32-bit) to medium (16-bit).
(YES, I had to repeatedly hit the monitor button and quickly move the mouse to do these steps, which was quite

challenging)

ALT-CLICK on a blank spot of the desktop; from the dropdown menu, choose PROPERTIES.

Click on the SETTINGS tab, where you'll see COLOR QUALITY dropdown box. Mine was set to High (32-bit).
I clicked on the dropdown arrow and chose MEDIUM (16-bit), and this solved my problem.

Hope it solves yours!
