View Full Version : Need help hooking HDTV (plasma) to PC

I recently purchased the 42" Philips plasma below and could use some help hooking it up to my PC.

I am using a XFX 6800 Ultra and have a few options to hook it up. Which way would be best?

1: S video cable (probably the worst)
2: DVI to HDMI cable
3: XFX supplied HDTV component out dongle with component cable

Also what resolution would you set for the desktop with a native panel resolution of 1024X768 16X9? Wouldn't 1024X768 stretch the desktop? How about movies, 720P?

Thanks for any ideas you guys can give. I am a total noob with HDTV's.

If yer connecting it via analogue component, the only resolutions you'll be able to use are:

480i, 480p, 576i, 576p, 720p, 1080i.

No other resolution will run off the analogue component output. ( You can run lower resolutions by using overscan compensation, but as far as Windows is concerned, yer resolution will be one of the above. )

'tis good for video, but not so good for games. If a game doesn't actually support one or more of the above resolutions, you'll get a zoomed in picture. I used 576i (720x576) via component and when trying to run games at standard resolutions ( 640x480 ) the image was zoomed in. Game menus didn't appear and most of outer part of the picture was lost, despite 640x480 being a lower resolution than 720x576. To fix the games I tried, they had to be hacked to run at 720x576 either via changing bytes in the EXE or messing with a config file.

This is for component output via the dongle. I have no idea how things are with DVI.

Yer options for connecting to yer TV in order of decreasing preference are:

1) DVI
2) Component
3) S-Video

I don't know what the difference between 1 and 2 is as I've never used 1, but there is a world of a difference between 2 and 3. The colour reproduction and the lack of 'noise' and colour bleeding ( particularly red ) with 2 ( as compared to 3 ) is quite noticeable.

Also what resolution would you set for the desktop with a native panel resolution of 1024X768 16X9? Wouldn't 1024X768 stretch the desktop? How about movies, 720P?

For yer TV:
Supported Display Resolution
Computer formats : 640 x 480, 60Hz, 800 x 600, 60Hz, 1024 x 768, 60Hz, 1366 x 768, 60Hz
Video Formats : 640 x 480i - 1Fh, 640 x 480p - 2Fh, 720 x 576i - 1Fh, 720 x 576p - 2Fh, 1280 x 720p - 3Fh, 1920 x 1080i - 2Fh

It depends. If you connect it via analogue component you'll all the resolutions at the bottom. 480i to 1080i including everything inbetween. If you connect it via DVI I think you'll get only the top resolutions unless you tell the nVidia drivers that yer set is a HDTV in which case it'll filter out certain resolutions. If you connect via DVI, which'll give the best resolutions suited to yer TV, 1366x768 is the one to go as this is a 16:9 resolution.

This is the manual for the nVidia drivers. It describes in great detail all the HDTV out options.
