My TV is definitely 1080i compatible (worked flawlessly with my Radeon and a VGA to Component converter). However as I found when setting that up the timing on the Panasonic TV for the HDTV was very specific, I needed to use powerstrip to get the timing just right, the built in 1080i support in the Radeon driver didn't seem to work.

Strange, as I would have thought 1080i was 1080i, ie a very specific set of timings that were compatible between devices. If I buy a HD STB that outputs 1080i I would expect that would work without tweaking on my TV which is 1080i compatible. Why is it so difficult with a video card that supposedly outputs 1080i???

There does seem to be some variance there, and the Radeon in combination with powerstrip gives the level of tunability that will allow it to work nicely.

Sounds like we are definitely seeing the same issues. One thing I'm interested in trying is to take the PC to a friend who has a 1080i compatible LCD TV and see if it syncs. I have a funny feeling that the 1080i implementation on the Nvidia isn't right.

The drivers otherwise seem very flakey in comparison to the Radeon I had, and just the general support for HDTV (which for me was the major selling point) just doesn't seem to be there. Certainly support for configurable resolutions is in the driver property pages, but it just doesn'y work.

As for the dual monitor situation, I've taken that entirely out of the equation (which is why I can now successfully get 576P). I'm almost writing off 1080i, although I hate to say that as high def programs at 1080i were just mindblowing on my old setup.

If I can just get 960x576 or similar I think I will be back to a position of having nice crisp text again, at 720x576 the text is not right, they are clear, but you can obviously see the chromatic abberation around the white text.

It would be nice to have a solution with native HDTV output without the converter in the middle, but that is looking a little ways of. I've tried posting to the Nvidia forums (as have a few others from what I've seen) and the response is zero. The feeling I get from that is people on those furms are either using DVI to a LCD/Plasma, or they are just gamers.
