Active Displayport Adapter Display issues
Hey there,

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.

Are you overclocking the HD 5970's?

Are they running 400e/1200m clocks in Eyefinity mode? Try using the overvolt tool to bump up the voltages and see if that makes a difference.

10.4 preview drivers are better for Quadfire HD 5970's but worse for Eyefinity. :\ 10.3b + App profile work best for Eyefinity for me on HD 5970, but 10.4 delivers performance scaling for CrossFireX.

Hey there caveman,

I am running the cards @ stock speeds.

As far as I can tell, the clocks are running @ 400/1000.

I tried ATI overvolt and the display seems stable. I did have to disconnect the displayport once, but it does seem stable thus far.

BTW, is there any way AMD can merge the 10.3b and 10.4 drivers?lol

I find it increasingly annoying to use "adhoc" methods/hacks to try and get things "working" in drivers that previously worked before. I understand they're "beta" drivers, but "Why fix it if it ain't broke?"

Thanks again caveman for the heads up.

Yeah, I understand. Hopefully it'll come together in 10.5 :D
