Then sue Panasonic for false advertising, see how far you get. Everybody knows if you have 720p you have HD. I'm not trying to justify anything after the fact. I know HD inside and out and I knew the set was 1024 well before I bought it. I still have 3 weeks to take it back for any reason if I want. You're the type of guy that would call 1080i x 1919 ED.
THE SET IS NOT ED......
Enhanced definition or ED is comparable to a DVD disc by featuring a 480p resolution, and is capable of displaying high definition signals at a lower resolution. High Definition or HD offers the best DTV picture with 720p, 1080i, and 1080p lines of resolution.

Enhanced Definition TV (EDTV): 480p
480p is an Enhanced Definition TV (EDTV) standard displayed using progressive scanning at a 640 wide by 480 high pixel resolution.
Interlace and Progressive Scanning Explained:
Prior to Enhanced Definition TV (EDTV) and High Definition TV (HDTV) video signals were all displayed in 480i. 480i is displayed with interlaced scanning at a 640 wide by 480 high pixel resolution. Based on 480i’s resolution there are 480 horizontal lines consisting of 640 pixels each. These 480 lines are called "Horizontal Scan Lines" and each one represents a path for a TV or monitor to draw a picture or single frame of video. Interlaced Scanning is a technique used to split each frame of video into two smaller parts called "fields". Each field of video in an Interlaced Scanning signal consists of either all the odd or all the even numbered horizontal scan lines for a single frame of video. Interlaced scanning is approximately 30 frames of video per second, which translates to 60 "fields" or half frames of video per second.
