I turn on my monitor and it works fine for about a minute then i lose the screen. It a vision quest monitor and I'm using it as my second monitor but its hooked up to monitor port 1 on my tower.

Press the power button of the monitor for a few second in 'of' mode then 'on', the popping add on the windows will just disappear.
This help solve my problem.

Does this VX900M version use the wallwart power supply or built-in power supply? Does it do the same when used it with another PC? No signal means it is not getting the video signals from your PC. Wenned to verify if it is PC or monitor problem first.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

The easiest method to fix this would be to simply go into catalyst control center (or AMD Vision Engine Control Center if you have latest drivers) and disable the second monitor. You don't need to disconnect it physically so all the cables can stay as they are, just disable it and use your computer as you normally would when the second monitor is powered off. Continue to use it this way as long as you like, but I would suggest rebooting the machine at least once before going back to the same place to turn the second monitor back on, and make sure you actually used some web links that previously would have tried to come up on the second monitor.

Once the second monitor is disabled, no matter what software or setting was responsible for causing the links to open on the second screen, the computer will only have one screen available so it will open on the first one. The software or setting should get automatically reset to remember this and a reboot while the second screen is still disabled should ensure that the setting is saved and whatever was making it open on the other screen will be reset to the proper one. Then you can turn the second screen back on whenever you like and leave it on and it should still open links on your main screen just fine.

The reason I ask you to hook up the viewsonic directly to the PC is to find out if the problem is in the USB adapter or in the monitor itself, you can also try your Viewsonic with other computer.
Basically just have the PC, VIEWSONIC, NO USB or the monitor. We need to narrow down the problem.

Unfortunatley your monitor is going out. I just had that problem. My sceen would come on, but after about 10min. it would blink off and turn black. I would have to hit the off button on the monitor, then turn it back on. It would work fine for a few minutes then black out again. I got a new/used monitor where I no longer have that problem.

I did check to make sure my hybernate was not activated, it wasn't, I had it set to never turn off.

Good luck.

Video (picture) must be constantly entering a monitor for a monitor to continue to display a picture after it self tests (goes on for a second or, two) Your monitor is fine; check it using another known good computer.

Hi, have you opened the monitor and looked for solder cracks on the video input connector

No problem.

The size will not be the same.

Ask for the size, you wants the same or a larger size.

Hi: For me it seams that the problem is on the graphic board that doesn't have enought energy to send information to the monitor. I sugest that you try another graphic board or another monitor on the same graphic board. ;) Regards
