I recently purchased a Sony KDL-55BX520, and noticed that there is some motion blur in action scenes and the picture is not that sharp. This TV was on sale at Walmart for $898, and usually retails for $1349 everywhere else, so I jumped on this deal. This tv has Motionflow 120 technology. It is connected to a Sony STR-DH520 receiver, with a Sony BDP-BX57 Blu-ray player, and a Dish 722k DVR. All have 1.4 HDMI cables (blu-ray and dvr into receiver and receiver out to tv). Blu-ray does look better, but still some blur. I have thought about having my tv calibrated from BestBuy, but that runs about $250. I'd rather see if someone might have the calibration settings for this tv, or could possibly direct me to a website that does. I have played with the settings, but really don't know what I'm doing. Any help would be appreciated. P.S. I also have a 55" Vizio E552VLE, that looks very sharp and action scenes flow without any blur. I used this tv to see if it was my Dish receiver or the cables, and all worked well in the same room.
