I have a 1080p Sony Bravia LCD I bought a few months back and I have not been able to get 1080p to show in ATV 2.0 list of resolutions. I know this has happened to some. I See 720p and 1080i. All three of My HDMI ports support up to 1080p res so what am I doing wrong here? I've rebooted the ATV a few times to no avail...

I would try the various resolutions on your TV to see which looks better. I suspect the upscaler in your TV might be better than the Apple TV's.

1080i vs. 1080p

i have hdmi from an upscaling dvd player to 1080p, which looks great for standard dvds, but i'm using component for the appleTV and can only use 1080i -- i rented michael clayton in HD the other day and it looked amazing -- to me it looked great -- my 40" samsung lcd is upconverting to 1080p anyway . . .

should i go pick up a HDMI cable just to say i have 1080p?

If you do decide to pick up an HDMI cable, do not buy one from a big-box retailer. They're very likely to gouge out your wallet and charge you somewhere from $50-$100 just for a regular HDMI cable, especially if you buy a Monster cable. Instead, there's an XtremeMac HDMI cable on the Apple Store for just $20.

I bought one of those and it gives me a really nice picture. I didn't personally try it side-by-side with a Monster cable, but some people wrote reviews on it after doing just that, and couldn't tell the difference.

Since your screen is 1080p, don't worry about it and just select 1080i (to use the Apple TV as a scaler instead of scaling twice). For content under 30fps, 1080i is the same as 1080p. Since the Apple TV supports a max of 24fps, 1080p is nothing more then a doctoring of the 1080i signal to be recognized as 1080p. It's the same amount of data just sent slightly different, but the TV will interpret and display both exactally the same.

*this does not hold true for 1080i screens

At least for me 720p and let the TV scale seems to look better than 1080i and let the Apple Scale

What is the model? Is this a flat panel LCD or a Rear Projection? If it's a Rear Projection, you might not have it set for 1 to 1 pixel mapping. This could result is a softening of the pixels that may be more pronounced in 1080 vs 720.

BTW - some of the early Sony Bravia 1080p LCD Rear Projection TV (18 months ago or so) do not except a 1080p input.

As I understand it, all 1080p movies have to go thru an hdmi cable to be 1080p. Otherwise the movie will be brought down to 1080i. I had this problem a couple months ago when I couldn't get my HD-DVD player to play 1080p thru my XBox360 because it was a first generation with no hdmi port. It was explained to me that when Hi Def was being invented, all the major studios got together and agreed that no 1080p resolution would be fed thru analog cables.
