Wireless adapter and dual monitor
Posted on 2011-02-18
I have a problem using dual monitors with my newly installed wireless adapter. The system is XP. I don’t have the make/model information with me, but I have an older Nvidia AGP card (has one vga connection and one dvi connection with an adapter to vga) and a new wireless adapter (don’t remember the make and model).
This is my second wireless adapter – both caused similar problems.
I can run a single monitor with no problem. But when I run dual monitors (and thus a different resolution and refresh rate) it will be perfect for a minute perhaps, then the second monitor will start to show a degraded (flickering warping) image and finally turn into a rainbow of nothingness.
I have the newest drivers for both adapters. No help.
I have tried lower resolution / refresh settings that still support dual monitors… but still have the problem. I have moved the wireless card to various different PCI slots without any difference.
It isn’t a resource sharing issue I don’t think.
Any good ideas out there?
