HD no longer working in 169.04 beta
I recently tried upgrading from the 100.14.19 drivers to the new beta 169.04 drivers. No changes were made to the xorg file.
When restarting X, the TV appeared to try to be outputting using s-video output instead of 720p. The screen resolution was 1280x720, but the TV was detecting the signal at 480i, and the display was gibberish.
Adding the line Option "TVOutFormat" "COMPONENT" to xorg.conf causes the TV to display nothing, and it reports that no signal is detected.
Downgrading back to the 100.14.19 driver corrects the issue.
