Question about ViewSonic VA712B 17" Flat Panel LCD Monitor

Viewsonic VA712b 17 " flat screen monitor

I just bought this monitor today, and can't get it to work. It worked for about 2 minutes, then began to flash back and forth from the screen to a black screen and then finally just went black completely. If I don't wait and try again immediately, the screen is totally black. If I wait a bit, it does the screen changing thing and then goes to black. I should mention that when the screen is lit, it seems to be shaky, as if some sort of current/disturbance is present. The computer I am using is a DELL Dimension 3000. Thing is, it seems to work fine when I plug into an old laptop (also a Dell) that I have. What's the desktop PC missing that the laptop has got? Or what's going on here? I read several of the other tips, but did not seem to see any that had to do with a brand new monitor... thx-

Re: Viewsonic VA712b 17 " flat screen monitor

Realheadache, Unusual problem, it could be the resolution and refresh rate setting your PCs video card is currently set at. I don?t know if this will fix your problem but its worth a try: - Now go to your PC with the old monitor connected, right click anywhere on the desktop. - Left click Properties from the box that appears. - When the Display Properties box appears click on the Settings tab. - Make note of the screen resolution. - Change the screen resolution to 1024 x 768. - Click on the Advanced button in the lower right hand corner. - In the next box that appears click on the Monitor tab. - In the Monitor settings section of this page record the value of the Screen refresh rate. Then change it to 60 Hertz. - Close this and the Display Properties box by click on the OK button. - Now try connecting your new monitor. Let us know if this helps and as always please don?t forget to rate this posting.
