I have been having an issue with the 10.4 pre and 10.4a pre drivers.
Upon installation, I started getting issues on the center (displayport adapter) display in 3 stages:
1. grey horizontal "interference" lines
2. intermittent display turning on/off
3. complete shutdown of center display
These drivers are the first to give "decent" frames using quadfire+eyefinity.
I've NEVER had these display issues with ANY of the previous drivers. Rolling back to 10.3 WHQL gave no problems again.
Unplugging the displayport adapter and replugging gave a temporary fix, but hardly an acceptable solution.
My active displayport adapter is certified by AMD-Accell Ultra AV DP to DVI-D Dual Link Adapter P/N B087B-002B.
I've read updating the card BIOS, updating the firmware on the adapter or RMAing the adapter are options.
My video cards are not overclocked and I installed catalyst software with default settings.
Frankly, I'm hesitant to flash the BIOS and RMAing the adapter isn't much of an option because I ordered from the US to Seoul. The shipping cost more than the adapter and they don't seem to sell them here.
Any suggestions or advice would be most welcome.
