Is my TV a HDTV?

Actually.. no it's not. Contrary to the concensus so far, your TV is NOT AN HDTV but actually an EDTV.. though I understand how the confusion emerged. I suspected this was the case at first, then did some research to further confirm my thoughts. EDTV stands for Enchanced or Extended Definition TV. That particular model is rather interesting as it supports many TV standards including NTSC, PAL, and all sorts of video input from different resolutions. Essentially the most the screen can display is 852 x 480 progressive. This does make it slightly better then a normal set as it is progressive and supports more horizontal resolution then standard TV, which is 720 by 480. This is of course because of the widescreen element of the screen. This essentially makes it a good standard definition TV for widescreen images, but not an HDTV. By Broadcast Format Supported, they mean that the TV is capable of taking input signals at 1080i.. 720p.. etc... but will scale it down to display at 852 x 480 (EDTV 480p) on your set. How well it does this I'm not sure... but it's still slightly better then watching something in HD on a regular standard def TV. For example if you actually plug a Blu-Ray/HD-DVD player up to it and watch a movie.. then compare it to the DVD of the same movie... the picture quality gain will only be minimal. There probably we be less noticable compression artifacts and the actual horizontal resolution would be higher.. since it can scale an actual 16:9 HD-DVD/Blu-Ray image down to the screens full 852 x 480 and take advantage of the extra resolution.. whereas as widescreen DVD is still only 720 x 480.. it just squeezes the widescreen image into the squarer picture space then stretches it out on your screen, thus less horizontal definition. But yeah.. long story short.. it's not high definition. If you compare HDTV or an HD Moviedisc on your screen and on a real 1080p/i TV.. you'll see the huge difference.

NO it's not. This one is only EDTV (enhanced definition TV). I pulled the user manual for PPM42S3Q which also covers the PPM50H3Q and the PPM63H3Q. The PPM42S3Q (the one you have) has a native display resolution of 852x480. It displays 852x480 progressive at 60 hertz so it can go up to 480p60. It's a progressive display with the same aspect ratio as HDTV (16:9 or 1.77:1 meaning the width is 1.77 times the height). The PPM50H3Q and the PPM63H3Q, however, have native display of 1366x768 which is more pixels than 720 but fewer pixels than 1080. You can watch HD on your TV, but your TV will display it at 480p (either 1080 or 720 input signals)

Yes in an HDTV
