I'm so pleased with the whole experience. Vincent was very pleasant and kept me updated prior to his arrival. When he arrived he took the time to explain what he was doing and how the adjustments could improve the picture. I was very interested actually. Maybe a career in calibration lies ahead for me (joke)! When all was done the improvement was obvious. Skin tones were rendered superbly and grey scale is no longer tinted. Sampling Dark Knight with the refined settings was astounding, then Spider-Man 3 in SDR and HDR further proved the value of calibration. Money well spent and I have no reservations recommending Vincent and HDTVTest. Thanks guys.
