Computer DVI output to HD display

phdutton · 29-05-2006, 23:00

I am about to buy an LCD HD pannel, it's got a DVI input, and my computer has a DVI out. I have several films in HD on my machine, and want to watch them through the display I am about to get.
My question is this, is there a specific way of outputting video to a DVI output on the video card. The card is an ATI X300 by the way.

Thanks,
Pete.

If you're lucky, you may get a DVI lead with your lcd tv to connect your pc to the tv. You will have to send the audio from the pc via your soundcard output to the RCA (phono) audio inputs on the tv. Also you will have to "enable" the second display output on your graphics card in windows. You will have to go into your catalyst control panel, and also make sure Hydravision is installed as well.

The audio wouldn't be an issue. Would much prefer to play it back through my computer, better speakers you see.
So, after I connect the DVI cable between the two, what happens? I'm guessing it'd just mirror my normal monitor out put. Is there a way of just sending the video down the DVI in it's native format (let the TV do the rescaling)?

Use the Catalyst control centre. You can either choose to mirror the whole output from your normal screen onto your TV, or you can make 'video' playback from within VLC player/media player/divx appear on either one. The other screen will just show a black window inside the player, no video playback. You may want to do this if you are having video playback performance issues. If not, mirror to both.

To be honest I don't find Catalyst not the easiest configuration tool to use and it gave me a right headache setting it up initially, but it does work.

You'll need to choose what resolution you want your TV to have from catalyst control too (most likely 1366 x 768), or you can choose 720P from the HDTV menu. If you are piping it into another room like me, you then realise you need a bluetooth mouse and keyboard... or a remote.

If you have Media Center, then the remote is definately the way to go! I have my PC in another room, with the audio/video cables and the infrared unit coming through the wall
