In my quest for a suitable screen to replace my aging JVC 32" I see plasma screens with vertical resolutions of 480, 768 and 1024. 1080 I think as well, not sure. Since PAL dvds are 576 and NTSC dvds are 480 (I am correct in this assumption, yes?) how come we are stuck with SD plasma screens with only 480 vertical resolution? With HD being 720 or 1080 how come HD plasma screens have a native vertical resolution of 768? Why not 720? I think I've seen a 1080 screen so that makes sense. So where does 1024 come from? I guess if the picture is good what does it matter, the internal scaler takes care of all the coversions. To me this doesn't make sense. The native resolution doesn't match the existing source, certainly in this country anyway. Finally if you've managed to stay with me this long without getting bored with my prattling on, can anyone who has had for a substantial period possibly side by side tell me of their findings with regard to comparison of picture quality between an SD and an HD plasma screen with PAL dvds because it seems to me that moving from a 32" CRT to a 50" SD plasma screen is going to be a retrograde step because of the increase in size and the reduction in resolution on PAL dvds. I'm not keen on buying an HD screen because of the cost. Maybe with time they will come down to sensible prices.
