hey guys, got me a 3870x2 running in my machine now and ive been trying get it to do my tv and monitor. It does the monitor fine but then on catalyst control centre when i go to change the resolution for the tv its giving me tiny little resolutions, which means i get a horrible picture.

The tv is a 32" lcd with full hd, so im a little confused as to what is happening.

Piccy below:

any ideas????

that screenshot is a little hard to read, but first off how are you connecting the HDTV to the card? Also what model is the TV? You might need to go to the manufacturers website and download a display driver for it to work properly. More details please mate

Are you 100% that your TV is 1080 since some manufacturers claim that 720 is HD.

Have a check on your TV's stats mate

Composite and S-video are made for resolutions of upto about 800x600. Above that resolution you need relatively high frequency pixelclocks which the cables can't handle that well (leads to a lot of signal loss).

When you connect a tv using s-video the resolution the card outputs (in case of the integrated tvout encoder of Nvidia gpus) is 720x480 (NTSC) or 720x576 (PAL) no matter which resolution you specify in your xorg.conf. The image is scaled to fit into this view.

If you really want high resolutions for tvout (HDTV) you should use either component or hdmi/dvi.

just additional info, if you're into HD movies & sound, get a HDMI cable (HDMI support both sound & picture), it's cheap (I get it for $15 /3 metres), easy to configure and great image quality (I'm using Radeon 4670 for my HTPC, 19"monitor for regular use, and fullHD TV for watching HD movies via HDMI, it's a no brainer)
