The Blu-ray and HD-DVD dispays setup at Best Buy are ISF calibrated if the market provides the ISF calibration service to customers. Look for tags on the TVs that say "This TV has been calibrated" Having a TV ISF calibrated is more important than what brand it is (SONY, LG, SAMSUNG, ect,) what display technology it is(lcd, plasma, dlp...), or alot of times even the source. I'm ISF certified and viewing/calibrating hundreds of TVs has really opened my eyes to just how great a picture can get. Contrast ratios on TVs can't be trusted from a retail store. They test it by pumping white at high contrast, measuring, then they turn the display off, and measure again. Very misleading. Have your tv calibrated, if you're in D/FW metroplex, look me up, I'll help you out.
