1080p HDMI output on 6800HD stopped working, 1080i works

December 2, 2012 3:19:47 PM


I recently updated my graphics drivers to 12.10 and after the upgrade my graphics card, a 6800HD, doesn't seem to be able to send a correct 1080p signal to my projector. I can select it fine and I can see my projector struggling to get a signal, sometimes getting it and showing a flawed, green-lined picture, but otherwise just saying "No signal." The projector has no problems with 1080p via HDMI since it shows a perfect picture from my PS3. If I set the resolution to 1080i instead of 1080p it works just fine, 720p also works fine. Any ideas? And before you ask; I tried going back to the 12.8 driver with no improvement.
