Hi!
I tried searching around for a few hours between google and here, and can't find my answer. I'm trying to hook up a MythTV home theater pc system and use my sony tv with it. I have the Sony KV-32xbr450 model, and it's currently using the s-video connection from the computer to the tv. On the computer side, I'm running Fedora Linux with a nvidia GeForce 4000 MX card.
Everything works fine, but I just want to know what resolution, color depth and refresh rate I should use for this tv. My biggest fear is that I will set something wrong and destory my tv.
Thanks for any information!!!
Mike

Welcome to Agoraquest! If you are using the S-video input, the input should be 480i with a 60Hz refresh rate. You will have to experiment with "color depth". The DRC circuitry doubles the number of lines to 960i. The only way to get higher resolution is to provide a 1080i 60 Hz refresh rate input to one of the component video inputs.

thank you for your response. I finally found another posting that spoke with the same example I used...even with s-video!
My next question, what is 480i? Is that 640x480, interlaced? I'm also guessing that I wouldn't be able to get anything higher than that because I'm using s-video and not component out.
Thank you very much for your help!!!
For those who are interested, here's the other post... I'm guessing it's from the same person...

Welcome to Agoraquest! If you are using an S-video input, the Horizontal Scan rate must be set at 15.75kHz (480i input). I suspect that the Horizontal Sync rate is the same. The actual Horizontal Scan rate for the KV36XBR400 is 33.75kHz, the frequency required for a 1080i input. The DRC circuit doubles the number of lines for a 480i input (15.75kHz) to 960i (31.5kHz). No action is required by the DRC circuit for a 480p input because it is already at the required input frequency for the MID circuit (31.5kHz). The MID circuit adds 30 lines above and below the 480 in each scan of the input to bring the count up to 540p. The DRC and MID circuits are bypassed for a 1080i (540p) input. You would have total control over your TV if you provided it with a 1080i or 540p(33.75kHz) input. That may only be accomplished using the component video inputs, VIDEO5 and VIDEO6, and apparently, a different video card in your computer.

Yes, 480i is the same as 640x480, interlaced.
