I just bought a Samsung 55" 6050 series LED LCD 1080p 120hz HDTV from costco for 00. its a pretty good seller right now. Well ive just plugged in my xbox after configuring the settings and started playing saints row 3 and i had some extreme lag, so i went and turned on game mode, which by just turning that on i noticed a very severe decline in graphic quality. It helped the lag decrease, but i still have some serious input lag when driving at high speeds. I have a HDMI cable for the input. Auto motion plus also seems to be turned off. i am very upset because the 40" Sony bravia i just replaced with this one looks alot better than this. Not to mention i just spent a day mounting up on the wall. Anyone have a solution for this, and maybe making the graphic quality better too? the graphic quality looks nothing like the sony bravia which was actually more expensive than this 55", the sony was around 00. it was a kdl40xbr6 model. looked amazing, but wasnt big enough.
