HI there! just wondering can anyone help me out. my tv is hooked up to my pc with a hdmi cable through my ati radeon 3800 graphics card. it was working well until recently the sound had gone first and ive just used the sound from the desktop speakers.the pc no longer gives an option to choose between audio outputs. i was able to play games and watch movies on tv but now the picture is becomin jumpy and pausin a lot. the picture is good on my pc monitor unless i have the hdmi cable from tv connected which makes monitor screen jump and pause also.ive heard it is ok to connnect this tv to pc via hdmi. im hoping its just some setttings i dont know about that is doing this.. im fairly new to computers so any help would be greatly appreciated.
