Hi, im looking to buy a a HD TV but im not what the main difference is between 1080i and 1080p. Is one better than the other and does it depend what you want to watch on TV as well?

All broadcasts are 1080i, so it won't affect broadcasts anyway, but Blu Ray is 1080p - so it may be slightly better for Blu Ray.

However, bear in mind both are the same resolution, but 'p' is theoretically better on fast moving action.

I would suggest the difference is pretty minimal though.

1080p sets will also do 1080i anyway. Like others have said, HD broadcasts are 1080i in the UK, so apart from BlueRay discs there's not much in the 1080p format.

Keep in mind that some 1080p sets are now offering a higher vertical resolution (the 2nd number) which applies to 1080i pictures as well as 1080p pictures. So these could offer a slightly better HD picture, even in 1080i.

......on the other hand, the higher the resolution of the screen, the worse the SD (normal non-hd channels) might look. The bigger the gap between the 2 standards the more scaling there is to do which can make the lesser format (SD) look worse. But each tv and each model varies quite a bit, so these differencies can often mask the technical variations. You need to see them working (and not just on a DVD or hard disc "demo loop", but on proper tv signals, HD and SD).

It doesn't matter what you get but 1080p is the best option.

Only if everything else is equal, there are many 1080i sets out there that are better than many 1080p sets.

There are also many 1920x1080 sets that are not as good as some sets with a lower resolution.

Don't forget Xbox 360, PS3 and Media Center PCs

And that not all 1080i have 1080 lines (mine only has 768 and is 1080i capable)

P stands for progressive scan which means whole pictures are on screen at one time whereas i stands for interlaced which means you get half a picture at one time. Obviously progressive scan is better.

Some may say that 720p is better than 1080i.

I have my Sony DVD Recorder (RDR-HX210) (non HD) to output Progressive Scan to my 1080P HD TV and it makes a fair bit of difference to the picture quality compared to using a Scart lead.

The other thing to think about is the actual screen size. I think the general consensus is the bigger the tv ie above 40 inches the better it is to have 1080P. Generally I don't think you can see much of a difference between 1080P and 1080i on 32 inch sets from what I have read.

However, judging in the shops you can actually sit alot closer to set which is full HD compared to a similar HD ready set when displaying HD material.

720p is better for fast moving sports, 1080i is better for films.

Sky HD is always 1080i so you don't really get the choice (the box will convert but that's not the same).

The size shouldn't make any difference as they both have the same resolution.

Ok bad de-interlacing can introduce artifacts that are harder to see on a small screen but even 1080p sets will be used a lot in interlaced mode so they have to be able to handle it good enough for your screen size at your viewing distance.
