Installed windows 7 on a dell sx260 with gem 17 lcd cant get display drivers to work?screen all dis colored

Try going to the Dell or Microsoft Websites and loading a new display driver for Windows 7. When I first got Windows 7, both my monitor and printers required new drivers for Windows 7. It seems that Vista and XP drivers for a lot of things don't work on Win 7.

Good Luck

I need a power cord/adapter for a GEM (Scanport) GL-821A monitor. It as a 12V 4.2 amp adapter type setup.

try www.12vadapters.com
You can use higher current rating but not lower, the voltage should be the same.

Power Issues!

The AC adapter will go into shut down mode if the monitor is drawing too much current due to short circuits in the monitor, but it can also be bad caps in the power supply itself. You can try new adapter or check inside the monitor for shorted components.

I have a GEM 17" with power issues!

Sounds like your power supply capacitors are causing the power supply to shut down. Or you have a short in the monitor loading the power supply. You should try a different power supply.

I didn't use the monitor for some time now when I connect it it flickers on and off is there a way to reset it? GL-821a 17" flat lcd monitors

Probably no reset function but a power supply with some failing electrolytic capacitors which can age even when not in use if they were poorly manufactured.

There is no image on the screen, and the power light blinks on and off while the monitor makes clicking sounds.
