Vincent is a knowledgeable and professional individual who has been to my home twice now to calibrate my TV’s! He’s not only very good at his job but a lovely fella to boot! My Sony KD65 ZD9 is now producing breathtaking images and my extensive collection has been rejuvenated. He calibrated it for HD, 4K, SDR day and night, HDR AS WELL AS GAME and 3D. All I can say is that I’ve had a lot of Kate nights re-watching my old favourites and they’ve never looked better. If you’ve spent good money on buying a top class TV then getting it calibrated is a no-brainer! Thanks again Vincent.
