So much for ATI Gold Star Super Plus Certification...
on June 30, 2011
This adapter is capable of doing everything it advertises, just not out of the box... sometimes... maybe...
I picked one of these so that I could use my new HD5700 series ATI card with 3 individual 1920x1080 monitors (all DVI). Some people report that theirs works immediately, some have trouble. When I plugged mine in, it fired up immediately and I thought, "great ATI certification was worth it...", only it wasn't working as I expected. The graphics card would not output a resolution any greater than 1440x900 to the display connected to the Displayport adapter. I have two different models of display and neither one worked. In fact, I got a message whenever powering up a new display which stated that there was an error (vague, very vague, with no real indication of what the error was).
I have a friend who works with Displayport test equipment and asked him to physically force a 1920x1080 signal through the adapter. It turned out that the graphics card was not negotiating things correctly, and the adapter worked. Now, nearly a 2 weeks after purchasing the adapter I know it works, but does not play well with the graphics card. I spent 2 days doing research on how to force output resolution with the Catalyst Control Center, only to find that feature seems to have been deleted at some point. AMD's website states that forced resolution is possible on all versions of Catalyst 9.7 and up, but good luck finding the "force" button.
Finally, I found a beautiful ray of sunshine in an obscure forum post. Accell has new firmware that fixes many of these known problems (All? Not sure, but it fixed mine). I am wondering if the people having problems have the old firmware, and people seeing them work off the bat have the new version. My firmware version stated it was 0x08, and the one replacing it was 0x95, big jump, no? Either way the firmware and instructions are available on the Accell website filed in the Support section under Displayport Products. Go here for the firmware: [...]
I give this adapter 3 stars because it works the way I expect it to, but took a very long time, and a lot of hair pulling to get there. I feel like Accell should pay me for finishing their product... If you get one, beware ATI did certify it, but I'm not sure how. If you are not comfortable digging through support pages and following instructions to update firmware for this product. I would not suggest you buy it.
