I had a Panasonic 65GZ2000 calibrated by Vincent Teoh of HDTV Test and to write a review of the calibration itself, which has elevated the display from merely being capable of presenting beautiful images to making appreciable the crafts of cinematographers and post production professionals; would be to miss Mr Teoh's value to the Audio Visual community. His YouTube channel is itself is an advertisement of the philosophy he applies to calibrations and one that he is influential in encouraging the industry at large to similarly adopt. Whilst calibrating my display Mr Teoh offered to walk me through his workflow and here demonstrated to me his meticulous attention to detail and comprehensive knowledge on the subject. He has since remained available to provide any answers to any questions I might have, and beyond being one of the world's foremost calibrators I found him to be a gracious and friendly individual.
