A. The 1080 and the 720 are the lines displayed on the screen. 1080 will give better detail.
The 120 an 60 are refresh rates, the number of times a second the image is repainted. 120 will have less flicker and will handle fast moving images better.
P means progressive and is to be desired. It means that the entire image is displayed with each pass down the screen. An alternative is I (Interlaced), where every other line of the image is painted with each pass down the screen; it takes 2 passes to paint the entire image. Interlace produces some flicker.
Old fashioned TVs are 512 lines interlaced.

What is the difference between HDTV and HDMI?
Q. I recently bought a LDC tv. Do I need to buy a Digital TV converter box?
I'm really confused between LCD and HDTV and HDMI. What is all of that about?

A. So I read through these answers and some of them sound like a 1st grader explaining that rain is gods tears. Some of the other answers are almost right. SO here is the real answer. LCD does in fact stand for liquid crystal display and is a type of screen that displays the picture passing light through small crystals. Not all LCD tv's are HD, it will say if it is an HDTV or not. A few years ago about half were HD and the other half just standard but now the majority of LCD televisions are HD. Also HD screens are wider giving you an aspect ratio of 16x9 which is rectangular as opposed to the older 4x3 aspect ratio that is more square. HDTV stands for high definition television, The "HD" is a signal displaying more lines of resolution than the old standard def. More lines results in a clearer more crisp picture. 1080p, 720p, 1080i, are the 3 different resolution line specs for HD broadcasts. Your HDTV may either be native 720p or native 1080p. A 1080p tv can display a 1080p signal which is considered the best of HD. Currently there are no networks that broadcast anything in 1080p, only bluray, XBOX360 and PS3 have 1080p content. All networks broadcast in 1080i or 720p. the number stands for the lines of resolution the letter "p" stands for progressive which is the way the tv scans the lines. Whether your tv is 1080p or 720p it will still receive all networks and if you have bluray or either game console it will still be in HD, the signal is just converted internally to 1080i so don't think you won't be able to display your xbox in HD, it just won't be 1080p and to tell you the truth, you wouldn't see a difference anyway between 1080p, 720p or 1080i. The "i" stands for interlaced which means the tv scans every other line starting with the odd numbers and then goes back and scans the even lines, all this is done at 60 times per second which gives you a picture. Progressive scans the lines straight down.
HDMI does indeed stand for high definition media interface and is a cable that is used to hook up an HDTV to HD devices such as HD cable boxes, bluray players, PS3, etc. The cable carries high def picture as well as digital audio all in 1 cable. You do not need to buy a digital tv converter box. Digital tv is not HD, its just a digital signal. In February 2009 tv is going digital, its not going HD. Basically it means that if you have an old tv and use rabbit ears antenna to get your signal and don't have a cable box or satellite then you would need a digital converter box to watch tv. This change over will affect maybe 15% of people who still use an old tv with an old antenna. In order to receive an HD signal you need an HD cable or satellite box.
