Knowing that a 1080p TV is better than a 1080i, is a TV that is rated at 720p better than one at 1080i? I have a 1080i TV that seems to be really acting up on me and may need to grab a new TV. I've seen some that are said to show at 720p. Would this be a better picture than 1080i?

Thanks. Later, QD.

Well my old school friend, A 720p signal is made up of 720 horizontal lines. Each frame is displayed in its entirety on-screen for 1/30th of a second. This is know as progressive scan (hence the 'p')The quality is like watching 30 photographic images a second on TV. A 1080i signal comprises 1080 horizontal lines but all the lines are not displayed on-screen simultaneously. Instead, they are interlaced (hence the 'i'), ie every other lines is displayed for 1/60th of a second and then the alternate lines are displayed for 1/60th of a second. So, the frame rate is still 30 frames per second, but each frame is split into two fields, which your brain then puts together subconsciously.Most of the time interlacing works fine, but for fast moving images, such as sports like baseball and hockey it can cause problems which manifest themselves as a 'stepping' effect on-screen. Progressive scan signals don't have this problem and so are better suited to sports.

A television that is rated for 720P can also play 1080i so that should not be a problem for you. Its just their progressive rating scan... but a 720P cannot play a 1080p which is 1080 horizontal lines all at the same instance.

Hope this helped:D

no tv is technically 1080i.

A Tv is either 1080 or 720. The signals are P or I.

720 tv's can handle 1080i signals and in some rare cases 1080p as well, although they down convert it to 720.

Unless u get a small tv (32 or smaller) u should definitely go 1080p.

To pick the best tv though, there are alot of factors to consider:

How much light is in the room during the peak viewing times *alot of light = no plasma*
How far do you sit from the tv? 10feet = around 42- 46". If you go larger it will be more like an entertainment TV. if you stick around 40-42. it will be alot more relaxing to watch the set.

Generally I find that people for main living room type tv get larger, bedroom = smaller. but thats up to everyone in the end.

I am (more than likely) getting into a 32" TV. Farthest viewing point is 15' max. Room is fairly dark. I have the original dark wood paneling from 1970 and a double window set in the room. It lights up pretty well, but the dark walls keeps it more dark. We like the 32" as well. Later, QD.

Depends on your price range. HD Channels are displayed at 1080i at the most, so a 720p will serve you fine for HD Cable. (my Comcast Cable box has settings for 480i, 720P and 1080i)

However, I know you also have a PS3, so for blu-ray movies, I think you should look into 1080P.

Then other things come into consideration: Refresh rate? 120 or 240hz? Size? LED , LCD or Plasma?


I'd say for 32 inch, don't go too much overboard. I have a 32inch Samsung, that is 1080p and has a digital tuner that I picked up from Best Buy for like 699 a year or so ago.

You can now get this: Samsung - 32" Class / 1080p / 120Hz / LCD HDTV
Model: LN32B640 | SKU: 9293445

for like the same price (Mine is regular 60hz).


Or better yet, get this baby: Sony - BRAVIA XBR / 32" Class / 1080p / 120Hz / LCD HDTV
Model: KDL-32XBR9 | SKU: 9222502 for like 699.

It's an XBR9 which is at the higher end of their line.

if you do feel its dark enough without direct light hitting the tv area, and step up from 32" to like 40-42" go plasma for the best picture. Panasonic plasma to be specific. Cheap when you find a good sale too.

At 32" tho, depending on how far you sit you will not see a difference between 720 and 1080. If your like 6feet away you can tell, 12 feet no. 10 feet.. maybe if you have really good eyesight.

Altho again with prices today, may as well go 1080.

Also about the samsung vs xbr9. U wont find a better picture than the xbr series from sony in any other lcd.
