What people are saying

Rated 4 out of 5 by from Great Picture I am enjoying this TV, best one I’ve every bought. We now have 3. Only concern, the stand for the 77 in makes the tv lean backwards. Had to lift the back; I’ve reported this but have not heard a word back. Just hope the stand does not break because everything will come falling down.

Rated 1 out of 5 by from My TV keeps power cycling I bought this tv back in April of this year. A couple of weeks later, it shut off by itself in the middle of a show. It then began to try to turn itself back on but couldn’t. The red status light would keep blinking and there would be a clicking sound when it did that. It keeps doing this even after we had a repair person come out to fix it. He out in a new motherboard but it seems that want the issue. I told them I think it’s a power supply issue but they didn’t listen to me.

Rated 5 out of 5 by from Fantastic Picture I bought this tv two weeks ago, and it is better than I expected. The picture is incredible, and the magic remote does so many things well. So many functions that I haven't figured out all of them yet.

Is the c1 77 oled supposed to lean back slightly when mounted on the stand. I was told this is not normal from lg but have read it completely normal to help with reflection and safety.

What is the difference between a OLED65CXAUA and a OLEDC1AUB? The CX indicates a 64.5" screen, whereas the C1 indicates a 65.4" screen, and both have the exact same outside dimensions. Is there any other difference?

The "X" in the model number (X is the Roman numeral for 10) for the LG CX 65 inch Class 4K Smart OLED TV w/ AI ThinQ® (64.5'' Diag), Model # OLED65CXAUA identifies the TV as a 2020 model and the "1" in the model number for the LG C1 65 inch Class 4K Smart OLED TV w/AI ThinQ® (65.4'' Diag), Model # OLED65C1AUB identifies it as a 2021 model. 2020 LG OLEDs employ LG's α9 Gen 3 AI Processor 4K Picture Processor and they run on last year's 2020 LG webOS TV Platform. 2021 LG OLED models employ LG's α9 Gen 4 AI Processor 4K Picture Processor.

I want to know the ratings for Sound Clarity/quality for the LG 48" TV Model #OLED48CXAUB.AUS

Asked by: Rarity
Regrettably, we do not have any ratings for the sound clarity/quality for the LG CX 48 inch Class 4K Smart OLED TV w/ AI ThinQ® (48.2'' Diag), Model # OLED48CXAUB. You may find online reviews from online reviewers like who have test results for different aspects of the TV, but there aren't any that have a sound clarity/quality rating for the TV. The TV features a 2.2 Channel Speaker System with an Output Power of 40W (20W Woofer). It is a WiSA Ready TV and features LG's AI Sound Pro / AI Sound where sound flowed around room obstacles to reach its destination, including you and the sofa. The LG Magic Remote that comes with the TV detects the position of the TV, as well as objects in your room so by simply holding it where you normally sit, it automatically learns your room layout and will set the sound up accordingly. The AI Sound Pro tech is meant to deliver the optimal sound settings for whatever content is being played through adaptive sound control, which means that the TV will analyze the room it is in and adjust the sound according to its layout...^IFV
