Hi all, time for much needed advice once again, this time in the TV arena. Been hitting the local B&M's and have narrowed my search down to 2 contenders. The Sony KP51WS500 and The Toshiba 50HDX82 From what me eyes tell me they are almost both identical, I have seen the stretch modes on both, the Tosh seems to have a slight edge, but I don't plan on stretching alot of material anyway. But my one major concern came up today trolling the forum for info. It seems that the Toshiba doesn't natively support 480p and up converts it to 540, where the Sony does not. Also according to the manual for the Sony it supports 720p, where the Toshiba also up-converts it to 1080i. I have yet to see what the up-conversion does, but around here popular belief is that some artifacts may show up. What exactly would I be looking at? Graininess? Blurry? Not exactly sure the proper definition of artifact. Now I am not sure how big an issue up-conversion is , but what do all of you Sony/Tosh owners think? Also any other flaws/greatness that either exhibits over the other, or that they both have. Besides the Flicker thing in the Pegasus guns. Thanx in advance, any and all help welcome. BTW, majority of TV watching is DVD and Video Games.
