S3 HDMI w/50" Panasonic

[FactorOfTwo]

I have a 50" Panasonic plasma, a TH50PHD6UY, with a DVI input.

My S3 arrived today so I connected it to my TV using the HDMI output, an HDMI -> DVI converter, and a DVI cable.

In 480p mode, things are fine. But if I switch to 720p, there is a 1" vertical strip of random static on the right edge of my screen. With 1080i there is also a strip of static but it is narrower. The rest of the screen looks perfect. The same screen viewed through s-video or component has no problems.

I'm pretty confident this is not a cabling issue. My suspicion is that the 1366x768 resolution of the display simply cannot be handled by the tivo. I am disappointed but not entirely surprised; 1366 is not divisible by 8, and the last time I checked, almost all PC video cards, even high end ones, can only produce DVI at screen widths that are a multiple of 8 pixels. Perhaps the S3 has the same limitation?

If indeed the hardware requires it, I would be OK if the tivo went up to 1368x768 and I lost two pixels, or maybe down to 1360 and left me with 6 black pixels. But the random static is intolerable.

For now I guess I'll switch to component cables. But having to convert my signal to analog and back again is really sad.

Has anyone else seen this? Tivo, can you fix?

The Panasonic should accept and rescale the 720p and 1080i signals. No set-top box or DVR on the market scales output to non-ATSC resolutions; rather, displays accept the ATSC standard signals and scale them to the appropriate resolution internally.

I would try another cable, just to rule out that issue.

Thanks for the quick response. I tried changing cables and that didn't help.

But I was able to "recenter" my TV's picture, using the Panasonic remote, to push the static off the edge of the screen. Now it looks OK. I thought that sort of old-school monitor adjustment was only necessary for analog connections, but I guess I was wrong.

Interestingly, from playing around a little more this TV (which is fairly high end) cannot display 480i over DVI. I just get a black screen. All the other resolutions work (480p, 720p, 1080i). Sadly the S3 has no video setting for "native, except 480i -> 480p". That forces me to use 720p hybrid, which is not terribly wrong for a 768 pixel tall screen, but it does mean that 1080i will not look quite as good as it could.

My Pioneer 5050HD has a native resolution of 1366x768 and I don't have any problems of this nature.
