The biggest difference between HD ready and a full HD LCD is the amount of pixels visible. TVs marked "HD Ready" have
1049088 pixels. TVs marked "Full HD" have 2073600 pixels. Nearly double the count.
Sky HD broadcasts in 1080i which means that if you have an LCD TV, the signal has to be converted to progressive scan and to the native dimensions of the LCD TV. This conversion can degrade the picture somewhat.
If Sky had decided to broadcast in 1080p there would be no conversion needed if you had a 1080p tv. That of course would mean a much better picture.
Most blu-ray players output 1080p.

The difference (as already explained by 10000maniacs) is the resolution of the panel for HD Ready and Full HD.

But then there's a second concern (which I think is what you are asking about), not all HD Ready sets will accept 1080P input, but this isn't a problem, as no source is 1080P only, so you just set the source to 1080i instead.

People go on about 1080P, but the difference is absolutely minimal, it's really of very little concern.

There's further confusion about 1080P, as there's 1080P25 and 1080P50 - with 1080P25 being no better than 1080i, as long as they both come from original Progressive sources. 1080P has the advantage of giving 50 pictures per second rather than 25 (like 100Hz TV is supposed to be), but I still don't see as it's a great deal better.

Thanks for that - I assume you did mean 1080P50 in the first reference. I have to admit that I struggle to see the difference between p and i settings on my Panasonic. It is only an "HD Ready" three year old Panny 720p/i so maybe I am not seeing the full picture (literally!). I have seen 50Hz vs 100Hz on Sony CRTs and the difference was stunning. What you are saying is that I would not be equally stunned by the 1080i vs 10180p difference?

I would say not, although I'm amazed you are impressed by the difference between 50Hz or 100Hz on a CRT - in my experience 100Hz is generally a poorer picture. In any case, there's really nothing it does to improve the picture, it's merely to stop any visible flickering (which only a tiny percentage of people can notice anyway).

I would suggets the difference you see is just the difference between the two sets - and nothing to do with frame rate.
