Great!
[This review was collected as part of a promotion.] It’s incredibly bright for movies, flawlessly fast for gaming, and handles low-quality streaming content better than any TV I’ve owned. If you want premium picture quality without the flagship price tag, this is the one to get.

A cut above the competition
[This review was collected as part of a promotion.] As a person who kept a 1080p plasma tv for many years past the advent of 4k, it was hard for me to make the leap. LG’s C-series OLED screens are the only modern solution for anyone who appreciates contrast and vivid colour and motion. The brightness is fantastic too. It’s hard now to go back to lower resolution, and I’m happy I made this C5 part of my daily viewing experience, especially when it comes to gaming and high definition streaming services.

Great oled tv
[This review was collected as part of a promotion.] I previously had a 65” oled which unfortunately the picture turned rather green for some reason just after the 5 years warranty ran out , but this was a great deal with the money off & a lot cheaper than my previous one, & the picture & features is unbeatable

Worth it
[This review was collected as part of a promotion.] This is the first OLED TV I’ve purchased and I couldn’t be happier. The colours are immense, and look sublime when streaming Dolby vision content. Deep blacks, and impressive resolution. Works perfectly with the PS5 and has lots of apps built in for easy viewing.
Craft
