Broadcast Television currently does not use 1080p. The HD formats in use at present are 720p and 1080i. The "i" stands for interlaced and it means that on a single pass of the screen half of the image is built up. The second pass sees the remainder of the image added to the first half. A full image is delivered 25 or 30 times each second. A 1080p signal delivers a full image on every pass, 50 or 60 times each second. 1080p therefore needs double the amount of data compared to 1080i. Broadcast infrastructure and the extra bandwidth requirements prevent 1080p being broadcast. 1080p is limited at present to Bluray and other local HD sources such as computers and game consoles. Don't expect to see 1080p from your television service provider any time soon. The 1080p identification on the television says that it will display 1080p but of course can only do this with a 1080p incoming signal.
Most modern LCD/Plasma TV's are capable of receiving and displaying 720i, 720p, 1080i and 1080p signals. Therefore your TV, if it can receive 1080i, should be quite happy with a 1080p signal.
1080p and 1080i both refer to the format of a video signal. Any HD television will receive the signal and display it. If the television reports the signal standard being received, it will let you know what the signal is. Therefore, the television cannot be changed from one standard to another as it simply handles the incoming signal. Currently, broadcast HD signals are almost exclusively 1080i with a few formatted as 720p. Both are considered full HD even though the resolutions are different. 1080p is found on some local sources such as games consoles and Bluray players but has not yet made it to mainstream broadcast services.
It has capability of 720P and 1080I HDTV, but does not have a TV turner to receive the signal and falls into the category of HD ready. It also is not 1080P the highest HD currently available.
1080p signal may not work on a 1080i TV set. You may not get a picture, but just a blank screen. And that blank screen will not let you undo the changes because you cannot see anything on the screen. In this case, you may have to make an analog connection, such as a composite video connection, to your TV set just to undo the changes you have made. Or you have to press a combination of buttons on the 1080p signal source to restore the picture. I suggest you read the documentation that came with your 1080p signal source.
you need a HDMI cable and 1080P media like a Blue ray disc and a HDTV with 10080P capabilities before you will receive full 1080P. For example most HD TV programing is only 720P and will not be in full 1080P on a 1080P HDTV and a TV show in 480i standard will be in 480i on a 1080P HDTV
If the TV is 1080p capable, it will switch automatically when it receives a 1080p signal. Keep in mind that not all cable and satellite systems will have this service. Look for the INFO button on the remote to see what standard you are receiving.
As of summer 2008, all satellite and cable companies in the US transmit only 1080i digital signal. When a cable or satellite service is used, there is no advantage of 1080p TV set over 1080i TV set. However 1080p sets usually come with some other more advanced specifications, which may make the image higher quality. Cable and satellite companies do not intend to upgrade the 1080i signal to 1080p in the near future, since this would involve high investment outlays and greater broadband capacity in their network. 1080p TV sets can fully utilize their potential when blue ray discs are played from DVD players.
HD televisions are capable of displaying a wide range of image resolutions and timings. Most larger HD televisions will accept 1080p, 1080i, 720p, 576i, 480i and each of these in several different field rates. The standard broadcast format for HD is1080i with 720p used to far lesser extent. The television shows "1080i" because that is the signal being received. It will only display "1080p" if it receives a 1080p signal. Currently, broadcasters do not transmit 1080p and have no plans to do so for a number of years from now. When playing standard definition material into the television, it is likely to display 576i, 480i or perhaps show the letters PAL or NTSC to indicate the standard definition signal format.
A TV can't display a resolution higer then it's max. Second, let's understand that the two consoles playstation 3 and xbox 360 both sends a true 720P signal. 1080P is actually a upconverted signal of 720P, so after knowing this, do we still want 1080P from our consoles?
No, the only advantage would be with video games or dvds/Blue Rays.
1080p
your xbox might be set to display 1080p and that's why it doesn't display on your 720 TVs
