Our take on the LG 77" Class 4K UHD OLED Web OS Smart TV with Dolby Vision G3 Series

The LG G3 is LG's gallery-style OLED, a 77-inch 4K panel built to hang flush on the wall with the included bracket. Its Brightness Booster Max and a9 AI Processor Gen6 push it brighter than LG's B3 OLEDs, which matters in a room with windows. Dolby Vision and Dolby Atmos are on board, and webOS23 handles streaming apps. It suits buyers who want deep OLED blacks and wide viewing angles in a bright living room and are willing to wall-mount; the rivals to weigh are Samsung's QD-OLEDs, which can go brighter in highlights, and the cheaper LG C3, which has the same panel family but a stand and less brightness.

About the LG 77" Class 4K UHD OLED Web OS Smart TV with Dolby Vision G3 Series

The LG 77-inch G3 Series is a 4K UHD OLED evo smart TV. It uses the a9 AI Processor Gen6 for picture and performance. Brightness Booster Max is available on G3 models. On the 77-inch size, LG's internal testing found images up to 70% brighter than on non-OLED evo B3 models.

It comes with a wall bracket that allows a flush mount, so the TV hangs like a picture on the wall. Depending on the installation environment, there may be a slight gap between the TV and the wall. Installation requirements vary, so check the installation guide for details. When you are not watching, it can display paintings, photos and other content.

The TV runs LG webOS23, which uses AI technology to cut down on searching for content. It supports Dolby Vision for color, contrast and brightness, and Dolby Atmos for wrap-around sound.

Questions and answers

Is the G3 much brighter than the LG C3?
Yes. The G3 uses Brightness Booster Max, which LG rates up to 70% brighter than its B3 OLEDs on 55 to 77-inch sizes. The C3 is brighter than entry OLEDs but sits below the G3.
Does it come with a stand?
No. The G3 is a gallery design and ships with a flush wall bracket instead of a stand. A stand is sold separately if you do not want to wall-mount.
Is it good for PS5 and Xbox Series X?
Yes. It has four HDMI 2.1 ports supporting 4K at 120Hz, VRR and ALLM, plus a low-latency game mode.
What is in the box?
The TV, the included flush wall mount bracket, a remote, and the power cable. A stand and the wall hardware for your wall type are not included.
Does it support Dolby Vision and Dolby Atmos?
Yes. It supports Dolby Vision for picture and Dolby Atmos passthrough and decoding, though the built-in speakers are limited for Atmos effects.
How does it compare with Samsung QD-OLED TVs?
Samsung's QD-OLEDs reach higher peak brightness and richer color volume in highlights. The G3 counters with a flush wall design, four full HDMI 2.1 ports and Dolby Vision, which Samsung sets lack.
