I very recently had my new 4K, LG OLED55B6V TV calibrated by Vincent. He is highly professional, very knowledgeable, precise and extremely passionate about his job. A self-confessed ‘perfectionist’, he was very thorough and meticulous and he talked me through the whole calibration process, encouraging me to ask any questions about the procedure. After the calibration was finished, I did notice an immediate improvement between the settings I had and those done by Vincent. After a few days, having viewed numerous programs, including the Olympics, Marco Polo, House of Cards, Bloodline and television shows familiar to me, I was able to identify even more positive changes. My LG OLED55B6V’s picture quality has gone from factory settings (good) to brilliant and just plain exquisite. I now have peace of mind of knowing that the picture we are watching is exactly what the content creators intended us to see. It makes the most sense to hire a professional calibrator if you have an expensive, high-quality TV. I am so glad now that I set aside a little more money to get a professional calibration rather than try and do it myself. After having it done, If you are thinking about calibrating your TV but are unsure, all I have to say is don't hesitate to get it done by Vincent.
