    Ok.

    I sit about 8.5 to 9 feet away. Should I still be good at that distance with that TV?

    Thanks for the help.

    yes at that distance you will be fine with the 720p

    don't get to hung up on the 1080i 1080p its more of a marketing ploy to get us to buy newer stuff

    Ok, I have another question.

    If a TV is 1200:1 contrast ratio and 6000:1 dynamic contrast ratio, is that good? I assume dynamic refers to something changing, but I am not quite sure which is more applicable to everyday use; contrast ratio or dynamic contrast ratio.

    There are a lot of contrast ratio measurements. The main types are Static Contrast Ratio and Dynamic Contrast Ratio. Of the two the Static Contrast Ratio is closer to a real-world measurement. Then there is also the Contrast Ratio of a display in a given room (light condition).

    Read this for more information...
    http://en.wikipedia.org/wiki/Contrast_ratio#Methods_of_measurement\

    Dynamic Contrast Ratio refers to a displays lightest gray and darkest gray when the entire screen (every pixels) is switched on (maximum; white) then off (maximum; black).

    Static Contrast Ratio refers to a displays lightest gray and darkest gray when the screen is showing both maximum white and maximum black at any moment in time (most often at the same time).

    Room Contrast Ratio refers to a displays lightest gray and darkest gray when the light in the room is combating the light from the display. It is a measure of how much light reaches your eye and how it affects the look (Contrast Ratio) of the display picture.

    It is a marketing ploy but with proper education it is easy to see through. Marketers want everybody to buy the latest and greatest. The easiest way to do that is to make the customer feel that there equipment is some how inferior to the new stuff. Not to say that 1080p is a passing fad but it isn't always appropriate and is mis-advertised, something that this thread has covered extensively already.

    I have been reading all of your posts and you guys would confuse everybody. I have tried both 720p and 1080i on my Sony 60" rear projection(1080i max) and also my Samsung 50" DLP rear projection(1080p max thru Hdmi or component samsung is the only tv do this)1080i wins all the time. You can argue all you want HD-Nut but when you all you watch is big screentv you can notice the differance. On my samsung the tv will display what resoloution you are watching on each channel and there is a big differance between 720p and 1080i.

    I guess you haven't read through this topic to well, the reason why 1080i looks better to you is because it is on a 1080p set.
    Compare a 1080i signal on a 1080i TV and a 720p signal on a 768x1366 set, there lies the difference!

    The 1080p set you have is made to weave together the 2 fields of 540 into 1080p much better than one field of 720p.

    1080i also looks better on a 1080i than 720p would look on a 1080i set because you are matching the sets native resolution.
    I know... I have done many tests...

    720p or 1080i it doesn't matter both are still an upgrade to the old stuff and yes we do understand that each channel is broadcast in a different signal. I get what your saying but that doesn't meen I agree

    I know your right about the signal upconverting to the native resoloution of your TV.

    Yea but if your set is 768p or 1080 you would have to be a cuckoo to put your set top or DVD player in 480p.
    You always want to match the resolution of your TV.
    The 480p setting for the box is for EDTV... native resolution 480p.

    Maybe his DVD player doesn't upconvert so he doesn't have a choice.

    Good point... But I was speaking in a broad sense as to why the 480p option is there!

    With fixed pixel displays you're really not getting a real 480p, say a native over the air signal was in 480p... my sets convert it to 768p, even though it's not a real 768p, it's not a real 480p.

    I think 480p sets are underrated. They are made to weave together the 2 240 fields of 480i to 480p, and the set downcoverts all 720p and 1080i signals to 480p. 480p sets will give you the most consistant picture of all.

    I was asking because a receiver I am looking at upconverts analog connections(s-video, etc..) to 480p.

    What kind of TV do you have? Do you have the product name & model # of the receiver?
