Absolutely amazing TV.
[This review was collected as part of a promotion.] I must say I am absolutely thrilled with my purchase. The 83-inch size is truly amazing and provides an incredibly immersive viewing experience. The image quality is stunning, and the TV is very easy to use, thanks to the excellent and responsive software. I'm also very impressed with the AI features and the overall sound quality. For those with a separate audio setup, the ARC functionality works perfectly, as I've connected it seamlessly to my external amplifier. This is a fantastic product and I highly recommend it.

White pixels in the middle of brand new TV
The day TV was delivered it had white spots. Not happy with an expensive TV with white pixels in the middle of the screen and that with only 1 year warranty. My first experience with LG TV, and I regret it.

Disappointed by non existent HDMI compatibility
Frustrating. We upgraded from a smaller LG OLED after only 7 years. The old TV was fully integrated via HDMI with all our Home Cinema devices and remotes. New TV offers no such integration unless devices are "LG compatible". I now have to use three remote controls: one for Satellite, one for Home Theatre and one for the TV.

Amazing tv, Webos not a big fan.
[This review was collected as part of a promotion.] Great Tv amazing quality, only issue I would say is the Webos is a bit glitchy and laggy. I have to mannually close my tv abd delete youtube application before it started to funcion apprpriately. Rest TV itself is state of the art, amazing television
