Set the video mode to 800x600, 60 Hz and then OK your way out, reboot and see if it's just you setting the video mode too far out.
hi, I've got a problem. When I hook up my pc to this hdtv it runs only to the moment of loading system and before login screen signal is disappearing, do you know what is going on? i use DVI-HDMI cable Prolink Exclusive. It runs properly only on failure/emergency mode
