My LCD Vizio HDTV keep switching from 1080i to 720p?

Hi Here's my understanding, your Hi Def tv will switch resolutions depending on input signal. If you have sat or cable you should see it switch from 480I on analog stations to a higher resolution such as 720P or 1080I on hidef content.

I have my LCD hooked to my PC so I always run at 1080 P and even low quality stuff looks great.

As far as 1080I vs 720P 720P is better, The "I" in 1080 I means every other line is blank so 1080I is equivalent to 540P.

The last LCD I had would only go as high as 1080I and I can certainly tell a difference between 1080I and 1080P but I do all my viewing through a pc environment and In my opinion a good PC video card does a better job than the Cable or sat boxes. If only everything looked like Blu-ray lol.

Hope this helps.
