im not sure if i have a bad board or not, but im not able to get a picture on the tv when the computer post, only once its loaded windows do i get a picture, on vga its fine. if i disconect my av receiver and plug the hdmi straight into the tv on post i get a stretched gigabyte logo before the os loads. any ideas? the tv is a Samsung and can do most resolutions. i had a ga-h67m before and that ran fine with the same tv. could it be a bug in the uefi bios or a faulty board?
