On an LCD, DLP or Plasma 1080i is presented to the screen at 30 frames per second (1080/30). 1080p is presented to the screen at 60fps (1080/60).

On a CRT it's interlaced or progressive scans.

That's it...

Theoretically...yes. Is there any 1080p content out there? Not on D**. Possibly on HDDVD players. I want to see 1080p content on a 1080i and 1080p side by side to compare. I read there may not be that great a difference. I won't pay the extra moolah for a 1080p at this point. Maybe in a few years. I am so happy to have HD (720P) at all!!!

If the de-interlacer works correctly on your 1080p TV, you will not see any difference between a 1080p signal and a 1080i signal.

1080p will in be better, progressive will always deliver a better picture than interlaced.

Why there is always at list one idiot misleading novices?

The question is I vs. P, and the answer is:

1080/2 lines per frame for I, and
1080 lines per frame for P.

If you are correct then it would never make sense to buy a 1080P. I think a 1080P monitor with a 1080p signal should have a better picture quality than a 1080P with a 1080i signal. It's like comparing 480P and 480i signal, there is an obvious difference.

The programing is out of our control. Currently it is all 720P and 1080i programing. Sometime in the future there may be 1080P programing available. The real question is: Should you shell out additional money to buy the 1080p vs the 1080i. Right now it's not worth it.

The short answer is P/Progressive is better yes... but for broadcast TV there may possibly never be 1080p broadcasts, due to the sheer size of the transmission.

Currently, you can only get 1080p, in it's true form, on Blu Ray Disc... not even on HD DVD as it doesn't do the proper fps timing, as it uses 1080i at 60 fps for the timing of a true 1080p signal, which is 1080p 24/25/30 fps. Playstation 3 and Xbox 360 also do 1080p games.

If you have a 1080p TV, your tv will upscale a 1080i image to 1080p by de-interlacing the signal, which is a 1080 signal sent in 2 halves to form a whole, and you should still enjoy the picture quality benefits.

That is an incorrect statement. You must be spending too much time with the Blu ray fanboy site which is filled with incorrect and mis-information. HD DVD does in fact do 1080p and in side by side comparisons there is NO visible difference.

what a waste of breath to argue about 1080p vs 1080i. It's high-definition. Unless you are comparing them side by side, you can't identify which signal you are watching anyways just by looking at it. The companies make a big deal out of 1080p to try and scam people out of even more money, and it's working.

I would respectfully disagree but, You sir are a moron, the above is a statement of FACT. Maybe you should do some research before you post a personal attack you can't back up.
