Hooking up a bluray player to my Sony 70xbr950, native resolution 788p, and assume many of you have done so already to 788p or 768p sets - so, what say you -output in 720p or 1080i? Thanks.

If it will accept 1080i then I would use that instead of 720p especially if most of the HD content you watch is 1080i content or if you have a blu-ray disk player.

Yes, it accepts both 1080i and 720p, but of course as a 788p native display it is "listed" by sony as a 720p set. So I've been trying to figure out if the set takes a fed 1080i signal and then deinterlaces / converts to 540p and then upconverts to 788p, as opposed to taking a fed 720p signal and upconverting to 788p. Is that the case, and if so, wouldn't the 720p output make more sense? Thanks for any thoughts, mates.

Some early "720" HDTVs did take each 1920x540 field of 1080i content and upscale it to 720p or to 768p as appropriate. However, newer and AFAIK all current genertion 1366x768 "720p" sets de-interlace 1080i input to 1080p and then downscale it to 1366x768.

From the review in the foollowing link it appears that your's does the former and therefore you should send it 720p content.

What's kinda interesting is I have a set that is native 1080p, but when I feed it HD content from my Dish DVR, it always looks better if I output from the DVR to 720p, even when it is receiving 1080i content. 1080i is definitely softer on my set.

What make/model of 1080p TV do you have?

It appears that your PVR is doing as better job of de-interlacing 1080i then your TV is.

Many of the 1080p HDTVs made in 2007 and even some of the 2008 models created separate 1080p frames by up upscaling the separate even numbered line 1920x960 fields and odd numbered line fields of the1080i/60 input to 1080p frames insead of de-interlacing the 1080i/60 content to 1080p frames using weave de-interlacing with motion compensation and your 5A3000 may be one of those which does this and this would explain why you get better PQ by sending 720p content which is upscaled to 1080p content.

I don't understand what you are saying here, but thanks for the explanation.
