hi, i had a long thread made but since that was going to be my first post, i put a link to the 42H83 tv i bought, but now im going to type the short version of my thread that dissapeared. first, when i pay my 480p widescreen xbox games, they look very jaggy, is there anyting i can do to reduce that? second, i have some of my settings at 40 contrast, 40 brightness, 75 sharpness and color temp at warm, will any of these hurt my tv in the long run? third, i was seeing a second blue image for a while, but i hit the refocus button and that fixed it, but will this eventually stop? fourth, when playing panzer dragoon orta, i noticed something that looked like the screen was a little fuzzy and was moving to the left, is this normal? last, i bought this tv at best buy with the 4 year warrenty at around $1437, but i couldnt afford dvd essentials but is there anyting i can do to improve the picture qualitly? i read somthing about a 9 point convergence, but i have no idea what that is.
