What is the difference between 1080p and 1080i? Is 1080p only found in blu ray players?

I have an hdtv and my dvd, when connected to a hdmi cable, can have different resolutions including 1080p and 1080i. But I dont really see any difference between both of them. What is wrong? What is the difference? If I buy a blu ray player will the audio and visuals be better?What is the difference between 1080p and 1080i? Is 1080p only found in blu ray players?
Well, 1080i and 1080p are different resolutions, some HDTV's are able to handle 1080p (high-end) resolutions, others are able to handle up-to a 1080i (mid) resolutions, still others are only able to display 720p (low-end) resolutions. The scale is as follows:



1) Best - 1080p - currently the best technology available (found in high-end HDTV's)

2) Middle - 1080i

3) Bottom - 720p



However, the difference between 1080p and 720p is barely noticable to the most trained eye.



To answer your question, you can only receive the resolution your hdtv is compatible with. Example if you have a 1080i HDTV and you buy a blu-ray player that is capable of displaying in 1080p, you will only get the 1080i resolution that your HDTV is compatible with.



And, I have both a 1080p and a 1080i hdtv and I cannot tell the difference.... Hope this helps.What is the difference between 1080p and 1080i? Is 1080p only found in blu ray players?
Basically the only difference is in how often a full-screen image is refreshed.



1080i refreshes at half the rate of 1080p because it uses a technique known as scan-line interlacing. It draws every odd line, then every even line - but it only goes from top to bottom at the same rate as the Progressive scan (1080p) and thus only draws a full image frame at half the rate.



1080p is pretty much beyond the eye's ability to actually see under most circumstances.What is the difference between 1080p and 1080i? Is 1080p only found in blu ray players?
