I'm looking at getting a new TV. I have an xbox 360 and Dish Network ViP622 HD Satellite receiver. I want to know what is the difference between 720p and 1080i. If I get this Philips 60" DLP TV which says 720p (http://www.samsclub.com/shopping/navigate.do?catg=535&item=338607&prDeTab=2&pCatg=8306#A) will I be able to use it in 1080i also or is it limited to 720p only. And if it is only limited to 720p what is the pros and cons to having this TV vs one that has 1080i and 720p capability?

It has 10000:1 contrast ratio also which to me seems very bright.

I currently have this TV but it keeps turning off by itself and Sams Club said it was a recall and to bring it back and exchange it. http://www.hp.com/hpinfo/newsroom/press_kits/2006/ces/ds_id5220nHDTVlvh.pdf This shows 720p at the top of the specs but then under video formats it shows all of them.

Thanks

The diff is lines of resolution and how they are displayed. 720p consists of 720 lines displayed progressively (all at once). 1080i consists of 1080 lines displayed interlaced (540 odd/540even).

Of course, theres also 1080p--1080 progressive lines. However there isn't much 1080p material out there. HD-DVD and BluRay are the only real sources of 1080p right now. OTA/cable/sat HD broadcasts are either 1080i or 720p, with 1080i being most common.

The set you mention has a "native resolution" of 720p. It will, however, accept a 1080i image and convert it to 720p. The only true 1080i sets around are the remaining few CRT-based sets and some plasmas. Every 720p HDTV made these days will accept 1080i and display it in 720p. Only thing it may not play nice with is 1080p.

First, the 720p DLP will automatically scale all inputs (480i, 480p, 720p, and 1080i) to 720p for viewing. Second, I would stick with the major DLP manufacturers, such as Samsung, Mits, or Toshiba.

720p and 1080i are both HDTV. But 1920X1080 has twice the spatial resolution of 1280X720, and most programs are 1080i. A 1080p display (1920X1080) should resolve the best fidelity programs or HD discs can deliver, while a 720p display is permanently limited to resolving only half of the potential full-format 1080i/p. So, since 1080p models are becoming widespread and less costly, you might want to consider a full-resolution display. -- John
