is sky hd any better with with a 1080p tv?
I think they are all on the 'sony ... I got problems' thread.
Don't take my word for it, I'm probably the least knowledgeable person when it comes to HT ( I'm trying to catch up quickly), but I gather Sky hd is 1080i and should in theory display better on an HD ready rather than full HD set. Less/no scaling to do. Having said that, of what I've seen on my set in the shop there's no problem whatsoever on a 1080p panel, even with the additional processing going on.
Well with an HD ready set you will get 720p and with a Full HD (1080p) ready set you will get 1080i. On my 40 inch screen, I cannot notice a difference between 720p and 1080i. However, if you have a receiver that upscales hdmi to 1080p like the big Onkyo beasts, you would be able to get 1080p from Sky (which you wouldn't with an HD ready screen).
In theory, a 1080p panel will be able to display a better picture (but not all TVs are equal). The TV will take the 1080i signal from SKY, de-interlace it (two frames of 1080i are combined to make one frame of 1080p) and display a 1080p picture. A 720p panel will need to downscale the signal from 1080 to 720 and in doing so will lose some detail.
Whether you can tell any difference between 1080p and a 720p panel will depend on how far away you sit and how good the deinterlacing/downscaling is.
