What ever it is, it still doesn't support it.
720p means 720 progressive. That means the lines that make up the TV image is shot across the TV screen 720 times, in a continuous way. Regular, or analog, TV resolution is 480i. The i stands for interlaced, which means there are two fields, or "pages" of information being shot across the TV screen at different times. 480i starts with line 1 at the top left corner, and beams the line across to the top right corner for line one. Line two is NOT on the same "page" so it is skipped, and line three is beamed across the screen. Then, line 5, 7, 9... all the way up, err down, to line 479. Then, the second field of the image is beamed across starting with line 2, then 4, 6, 8.. all the way to 480. Each field has a hz rating of 30hz. They add together to make 60hz. It's the combining of these two fields that make regular TV so damn blury.
480p, 480 progressive, is digital or analog standard-definition TV, but with only one field of information. The image is beamed across the screen continuously at 60hz. That is why progressive is so much sharper and clearer than 480i. The TV doesn't combine anything together at a slower hz speed like 480i. Digital 480p is sharper, brighter and more colorful than analog 480p.
720p, yep, is 720 progressive, which means 720 lines are beamed across, instead of 480. Which makes for a better, sharper image, hence the name high-definition. It is digital, only.
1080i is 1,080 lines being beamed across the screen, but in a interlaced way, sort of. 1080i high-definition beams the image, starting with line one, at the top left corner, and stops at the middle of the screen. Then, beams line two, and every line after that up to 1,080 the same way. It's shooting the lines in a "progressive" style, but can't be called progressive because there are two fields being "interlaced" together. But, this time the second field is the right side of the picture, which of course starts at mid point line one, and beams to the far right of the screen. Doing it this way offers more lines of resolution for a sharper image compared to 720p, but there is no bluriness like with 480i, because it's shot across the screen in a progressive way. But, the left side image of 1080i is 30hz, and the right side is 30hz, and 720p is 60hz. That means 720p can give a more fuller, warmer picture compared with 1080i, and has no "dot crawl" or "flicker" like 108i. 1080i has so many lines of resoultion, and is being beamed at 30hz only, the TV computer can't beam a completely solid image when the action of what is being displayed moves around so fast. When this happens, the image starts to "crap out" with a distorted image. But, no need to worry. Most HDTV sets transfer 720p into 910i, 820i or 540p making for a similar image to 720p that most everyone can't tell the difference.
Even 16:9 sets will display anything that isn't 1.78:1 with black bars (vertically or horizontally).
