Hi all,
I just bought a PowerColor Radeon HD 7950 video card, replacing an MSI 5770, and I'm having a strange problem with the DVI output. I've tried connecting it to two monitors. One one, there is no signal at all - the monitor just shows black. On the other one, there is a highly garbled signal (flickering lines, off-color pixels popping up) intermittent with just black.
The HDMI output is fine, and I can connect to my monitor using an HDMI to DVI adapter (through that's not a good long term solution as I want to connect the HDMI to my TV). Everything else about the video card seems to be working fine.
Things I've tried that have not fixed the problem:
-Connecting to a different monitor (as mentioned above).
-Using a different DVI cable (but I only have single link - see below).
-Flashing the BIOS on my mobo to the latest version.
-Disabling the integrated graphics through the BIOS.
-Removing and re-seating the video card.
-Copiously restarting the computer and the monitors.
-Downloading the latest version of drivers for the video card.
-Deleting the MSI Afterburner software for the previous video card.
The only other thing I can think of is that maybe a dual link DVI cable might help, but I don't see why that would be necessary, as the monitors I've tried have 1920x1200 and 1600x900 native resolution, and worked fine with the old card and same cable.
The card is reading 28 degrees at idle on HWMonitor, so heat is definitely not the problem.
I'm definitely thinking this is a defective video card issue, but I just wanted to see if there were any other potential fixes before I RMA the thing. Thanks much for your help!
