What people are saying

Rated 5 out of 5 by from LG OLED G2 We had our TV installed yesterday and binge watched for 4 hours. It’s amazing the color, clarity and brightness. However, be aware we had an issue with the flush Mount bracket. It forces you to install the TV between two studs. Therefore we couldn’t install the TV centered on the wall bump out we had built for the TV. We had to use a different bracket to center it and the TV is 2” off the wall. So much for looking like a framed picture.

Rated 4 out of 5 by from Awesome picture, needs calibrating I bought this TV and straight out of the box it has a good quality picture. The true blacks are amazing, you need low light environment to appreciate it fully. The TV can be better calibrated if you go into settings, and I think this is a necessary adjustment.

Rated 3 out of 5 by from Manufacturer defect? Panel appears to be suffering from a manufacturer defect and is already failing with what appears to be a big 'splotch' (dying pixels?) in the middle of the screen

Asked by: Rmac 11
All TVs will play video signals that they are presented with at their native resolution and when presented with a video signal with a lower resolution, they will upscale that incoming video signal to the TVs native resolution or as close as the built-in upscaler in the TV can get the signal depending how much data the signal has. The LG GX 55 inch Class with Gallery Design 4K Smart OLED TV w/AI ThinQ® (54.6'' Diag), Model # OLED55GXPUA has a native resolution of 3,840 x 2,160 which is also referred to as 4K or Ultra UHD resolution. The TV has a built-in 4K Upscaler (AI Upscaler) and it features HDMI 2.1ports that support 4K @ 60Hz and 4K @ 120Hz. If your DVD is a 1080p resolution DVD, the AI Upscaler will upscale that resolution to the TV'snative 4K resolution...^Ivan

Do any of your OLED TV's have center channel inputs so I can use the TV's speakers as a center channel? If so, which models?

Asked by: BigTipper
None of our 2020/2021 LG OLEDs have Center Channel inputs. They all either have HDMI eARC ports or Optical Digital Audio Outputs for audio. Audio can be played through the TV’s Internal Speakers and External Audio Devices simultaneously. You can use the TV's built-in speaker and Bluetooth speakers for simultaneous sound output that provides you with realistic surround effects when watching a movie or drama, and you can connect up to two Bluetooth devices of the same model to set the left/right surround sound. Audio is played through the TV’s built-in speakers and the audio device connected to the digital optical audio output port simultaneously. You can wirelessly connect the TV to WiSA Speakers to enjoy high-quality sound and select DEVICE LIST to adjust detailed settings for WiSA Speakers...^IFV
