I had my LG55C8 calibrated over 18 months ago now. The calibration included day, night ISF mode, HDR & Dolby Vision. After completing calibration I thought the picture looked good, but to me seemed to have a slight blur to it. I have 20/20 vision so dont wear glasses but Vincent said that my eyes will adjust to the picture over time, so I thought ok, but weeks went by and still the same and the picture just didnt seem right. Anyway after tinkering with contrast, brightness and de-blur & de-judder I thought I'd not got what I paid for. Then I messed around with settings on my Panasonic UB820 player and after so much going back and forth changing settings on the player I finally sorted it AND it was colour saturation which was too high and by lowering it to -2 the picture is absolutely stunning with every film in standard HD & HDR just popping. Dolby Vision is not impressive. For some reason no adjustments have been made to the 2pt or 20pt or any other setting and cant make the same adjustments as I did for HD & HDR so I'm so happy about that so I've had to turn off the Dolby Vision setting on my player.
