Wonderful OLED TV from 2025 lineup
[This review was collected as part of a promotion.] I purchased the 55 inch version for our living room and very impressed with the picture and operating system. Our principal bedroom TV then decided to stop working, so decided upon the 48inch version too. Not disappointed! The picture in UHD with Dolby Vision and Dolby Atmos is superb

Great value, bright screen
[This review was collected as part of a promotion.] My first OLED TV purchase, and I cannot fault it. Great price and value for money, excellent sharp and bright display. Highly recommend

Excellent TV
[This review was collected as part of a promotion.] Excellent picture. TV bought for the conservatory and so a bright screen was required. This OLED TV delivers and with sufficient sound, no sound bar required. As with all modern TVs it took a whilst to set up but worth it. Very happy with my purchase
Jeremy Kelsall
Extremely Happy!
[This review was collected as part of a promotion.] Extremely happy with the TV! Performance is near perfect. Would have been 5 stars but for the position of HDMI (ARC), I personally would prefer connection further into the back of TV but can understand why connection is placed for easier access.

LG oled C4 42" Flight Sim TV
[This review was collected as part of a promotion.] Just got the LG oled C4 42" a week ago. So far I find it great. Picture quality is perfect and no latency. Got it to replace my Samsung Odyssey Neo G9 49". Ultra wide just didn't do it for me. I find the LG 42" more immersive and possibly the perfect size for the gaming I do.

Amazing Purchase
[This review was collected as part of a promotion.] Great TV . The OLED panel is beautiful as expected and cant praise enough. what stands out are the spekers on the panel. Crisp sound quality. It come with a beautiful mount stand in case you dont want to mount on the wall.
Prasiddha, Dublin
Great Oled TV, LG Smooth interference but Sound ru
[This review was collected as part of a promotion.] Great ! but sound is rubbish, i like the LG platform, its smooth and easy, however casting videos using Chromecast is a nightmare, too many glitches and always getting disconnected. LG needs to improve its tv speaker sound, its outdated, my 10 year old tv has better sound, unless you are planning on using soundbar from LG, i would recommend going Sony

Bent Screen, can’t detach the power cable. Saddddd
[This review was collected as part of a promotion.] Screen is slightly bent and they missed the delivery. For a TV that is over a grand you wouldn’t expect this.
