nvidia 6800 or 7800 hdtv out quality

[ropscot]

Hi, I currently have a ati x300 card and have tried to connect it to my 62 inch dlp tv via s-video and it has bad overscan. I was looking at the new avivo from ati and it looked promissing, but the x1600 isnt out yet and I feel the nvidia 6800 or 7800 is a better deasl than the x1800. So how is the hdtv output on the nvidia cards
thanks

HDTV support over svideo is not only lousy, it's nonexistant, just like it is on all devices that output svideo only.

You need to use DVI or find a component dongle (not sure if these are available for nvidia cards, though) to hook it to your TV. HDMI will also carry an HDTV signal, but I'm not aware of any video card that supports HDMI output, though there are DVI -> HDMI converters.

I know ati and nvidia have the dvi component dongle and dvi, but was wondering how the overscan is handled on the new cards, I heard the avivo was suppose to be great
thanks

I have an HDTV hooked up to one of my computers, running an Nvidia 6600 card. I am using the component adapter. Nvidia drivers will allow you to correct for overscan. Picture quality on DVD playback, using Purevideo, is excellent. I can only output 720x480p on DVDs, though, unless I strip out the Macrovision protection.

I don't have much experience using ATI cards for HTPC.

Depends on your TV. Even on the FX5200 in my HTPC, I can run a custom resolution that gives me very little overscan. PQ is great.

I've hooked my 6800GT up to an LCD rear projection HDTV over DVI before (and will actually be doing it again in a few days at a LAN party) - it works great. The drivers auto-detect the TV and set up a resolution with little to no overscan (and you can adjust it in the drivers if you so desire). Picture quality is outstanding (as would be expected over DVI).
