Bought the latest LG Oled 55" in May and whilst colours were good, watching sport was frustrating . Experienced ' juddering' as well as a shadow around the moving ball. Retailer agreed to take back the set but I was still of the view that I had bought the best tv. It was then suggested to me that I explore professional calibration. Delighted we did. Found Vincent via website and the result is stunning. Problems resolved and picture colour balance and clarity of picture superb. Having already spent £3k plus buying the TV set, the best investment was the calibration. If in doubt, go for it, worth every penny.
