My tv had a pretty good picture out of the box but not great, so I decided to contact Vincent from hdtvtest, glad I did, this guy knows his stuff. He turned up at the arranged time with all his gear and began to calibrate my tv explaining what the new settings would do for the picture. After an hour or so you could see how balanced the colours were, more depth and clarity even with sharpness at 0, no on screen artifacts and motion is great. I have watched all sorts of content, sports and movies and after the calibration in a nutshell superb. I would not hesitate getting Vincent round again to calibrate another tv for me, if you own a premium tv and want to get best out of it contact Vincent and he will do his stuff.
