I understand the difference between 480, 720, & 1080 lines of resolution. 480 looks bad on a 1080 set. The larger the set, the more pronounced the difference gets. Yet, there are inexpensive upscaling dvd players that make 480 dvds look at least passable on HD sets. The picture can be displayed at 1/2, 1/3 or 1/4 size. I've seen advertisements on HD channels that are being shown at reduced size also. So, are there any HD sets out there that allow one to shrink the picture size to a point where SD looks okay?
