I got done building my PC a few months ago. I have an 8800 GT video card and tried hooking up to my TV via S-Video. This came out really poor quality and just not good. What would be my best option for getting a good solid HD input from my computer? Do I need a different another card? Would I also need audio out? Here is my current set-up:
-Thermaltake Soprano DX VE7000BWS Black 0.8mm SECC Chassis/ Aluminum Front Bezel ATX Mid Tower Computer Case
-Ultra X-Finity 600W
-ASUS P5N32-E SLI Plus nForce 650i Socket 775 ATX Motherboard

-Thermaltake CL-P0401 V1 110mm Full-Range Fan CPU Cooler
-Seagate Barracuda 7200.10 ST3160815AS 160GB 7200 RPM SATA 3.0Gb/s Hard Drive
-Western Digital Caviar SE16 WD3200AAKS 320GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

It's not your PC its your TV.
If your TV dosent have VGA, DVI or HDMI input forget about getting any good video out of the TV.
If your card has a SPDIF connector you can get sound,via jumper, through a DVI or HDMI interface.
You will not be able to get a HD signal to your TV using the S-video input.
S-video and composite connections can handle resolutions of upto about 800x600. Above that you need relatively high frequency pixelclocks which the cables can't handle that well (leads to a lot of signal loss).
Also, when you connect using the s-video connection your video card outputs is 720x480 (NTSC) or 720x576 (PAL) no matter which resolution you specify in your card setup, it a TV-Out compliant signal. The image is scaled to fit into this view.
If you want high resolutions for tvout (HDTV) you need to use either component or hdmi/dvi connections. If your TV does not have these connections you are out of luck.
Options to connect to HDTV is below. Both will enable you to operate at 1080P resolutions including watching Blue_ray, HD-DVD movies. I have verified these connections to work on different video cards including 8800GT 512 OC.
I have an 8800GT connected to HDTV through DV/HDMI-converter connected to the HDMI input of the HDTV. This is the best setup.
If you want to use the analog-connection using the analog-expansion cable that came with the video card.
