VGA adapter can't handle 1920x1080@60Hz ?
I just found this sub forum so I'm reposting my problem into the proper forum if that's ok.
I bought an Air two days ago with a VGA adaptor, for use with an iiyama 24" VGA monitor.
When I set the monitor to its native 1920x1080@60Hz resolution, I get fast moving zig zag disturbance all over the screen that quickly comes and goes, continuously.
I've tried a different VGA cable and even a different VGA monitor (an HP 2007w). Both monitors have the problem, and only at 1920x1080. When I set either monitor to a lower resolution, the disturbance goes away. Of course I want to be able to use my iiyama's native 1920x1080 resolution.
Any ideas? My guess is that either the SVGA adaptor or the Air's graphics chipset is flawed in terms of driving VGA monitors. I hope I'm wrong.
