Here's the issue: I have three Samsung SyncMaster S27B550Vs. My computer has three outputs: HDMI, VGA, and DisplayPort. I have one hooked-up through HDMI, one through VGA, and I'm trying to use the DisplayPort to enable a third monitor. The adapter plugs into the DisplayPort and gets its power from a USB port on my computer. The adapter provides a dual-link DVI (female). I'm using a dual-link DVI to HDMI to connect the adapter and my monitor. However, the display simply won't identify in Catalyst Control Center, or in the Windows display configuration page. I've tested the DVI to HDMI cord on another computer. I've tested the DisplayPort with a DP to HDMI passive cable. Both of them work. Has anyone else had trouble with a similar setup? I tried contacting Accell regarding my issue, but they're extremely hard to get a hold of. Apparently you need an account that you can only get through talking with a representative to access their firmware and downloads page. Someone please help.
