Sorry for the long post.
I have a Sapphire 512Mb Radeon HD 4670 with two monitors connected on vista 64x.
I'm getting an intermittent video error, “Driver failed to respond, but has recovered”, Which flashes a few times and then the system dives with a BSOD, memory dumping from ATIKMDAG.SYS.
A few places on the net suspect that it's a dual monitor problem, where an old monitor is involved. In some cases replacing the old monitor meant the error disappeared.
I looked into this, and discovered something wierd.
Left monitor is an ATEC 18.1 connected on DVI
Right monitor is a Samsung 22" Syncmaster 2232BW on DVI.
In ATI Catalyst, these are listed correctly.
1. Monitor is ATEC 18.1
2. Monitor is Syncmaster 2232BW
The little graphic looks right, small monitor on left, big on right.
However, in windows Display settings, this is the wrong way around, suggesting windows is trying to use the driver of the wrong monitor.
1. Monitor is Syncmaster 2232BW
2. Monitor is ATEC 18.1
The little graphic looks right, small monitor on left, big on right, but if I click on the small monitor, it tells me that it's the Syncmaster 2232BW
I can't find anywhere for me to tell Windows it's got it wrong. All thoughts welcomed!
