Having had the LG OLED65C6 nearly 3 years the temptation to look for deals on the latest models was getting stronger but now after a visit from Vincent its like having a new tv, its that good! Being an AV fan I was already aware of HDTV site & seen loads of the youtube videos, apart from being really informative they have some genuinely laugh out loud comments...perfectly delivered, dead pan stylee! As soon as Vincent arrived he got straight on with setting up the calibration kit & set about working his magic. Now I'd thought the picture, with settings I'd picked up from forums etc wasn't too bad but could instantly start to see we'd been watching in a little known LG setting called Hulk mode. Cutting to the chase, the difference after calibration is huge, as I've said its like having a new tv which makes me want to re-visit loads of programmes/blurays/UHD discs previously watched. Apart from fabulous colour accuracy & contrast the blacks now have loads more shadow detail, great tonal subtlety...overall the picture now 'pops' & has a vibrancy (without being vivid!) & great sense of realism. When time comes to splash the cash on a new tv the first thing I'll be doing is contacting Vincent to book him in for a visit, apart from his incredible technical skills & knowledge, he's just a genuinely really nice friendly guy, thanks Vincent. If you're still on the fence then jump off it and get him booked in!:)
