I never actually knew the difference between 1080i and 1080p, but I'm pretty sure 1080i is better than 720p. What screen size are you using? If it's small, you will hardly notice a difference.

1080i interlaced, 720p is progressive.

If its a CRT - 1080i generally looks better.

If its a LCD/LED/Plasma - Definitely 720p

It's a Panasonic 42" LED IPS 120Hz. So 720p will look better than 1080i in this case?

1080i CRT or 1080p HDTV = 1080i > 720p You should only use 720p if that is your television's native resolution. 1080i looks much, much better than 720p on any 1080p HDTV...

It really depends on the tv and the content being watched. 1080i on my lcd hdtv looks better than 720p, of course it will artifact with lots of motion.

Ohhhh, that explains why things in motion look so weird on my TV. I'll try switching to 720p to see if that helps it

Just for info, some TV channels aren't broadcast in 720p even, it could be 576p (I know in Australia there are a few ;) )

You need to watch different things, dark movies, fast sports action, blu-ray movies etc etc.

You can also buy a cheap calibration DVD if you want, or get a professional calibrator.

If your TV is natively 1080p than 1080i will probably be better. If your TV is natively 720p, then 720p will look better as your TV will have to down convert it to 720p anyways which can introduce artifacting.

This. Forcing your TV to use a non native resolution usually results in pretty crappy results.

in the early days of 1080i it was actually a bit of a piece of jargon being used as a claim as essentially 720p and 1080i were the same

Screen size alone has nothing to do with it, you also need to know viewing distance. You can notice the difference on small screens if sat close.

Nonsense. 720p and 1080i have never and will never be the same. 720p is 1280 x 720 and 1080i is 1920 x 1080, totally different. The actual image of 1080i should look exactly like 1080p as they both have the same amount of detail in them, the only thing to suffer would be motion and even that's not bad on decent TV's.

1080i will be upscaled to 1080p on 1080p sets and will be downscaled to 720p on 720p sets. In the old days with CRT, 1080i could look better as those TV's could natively display 480i, 480p, 720i, 720p, 1080i and some even 1080p natively. With fixed pixel displays, interlacing is a thing of the past as all these tv's are natively 720p or 1080p. The difference today is that 1080i upscaled to 1080p is an easier process with better results usually than 720p upscaled to 1080p. Same can be said for 720p will look better on 720p sets with no scaling compared to 1080i downscaled to 720p on native 720p sets.
