Our take on the LG 77" Class 4K UHD OLED Web OS Smart TV with Dolby Vision C3 Series - OLED77C3PUA

The LG C3 is a 77-inch 4K OLED TV built on LG's evo panel, with the a9 AI Processor Gen6 handling upscaling, tone mapping and picture-mode selection. It supports Dolby Vision and Dolby Atmos, runs webOS with the major streaming apps built in, and has an almost invisible bezel plus a gallery mode for art and photos. Against its rivals it sits below the brighter G3 MLA panel but costs far less, and it beats most LED-LCD sets on black level and viewing angle while trailing them on peak brightness in bright rooms. It suits movie and console gamers who want deep blacks and HDMI 2.1 features in a large screen.

Best forMovie lovers who watch in dim or dark roomsConsole gamers wanting 4K 120Hz and VRRLarge living rooms with 8 to 12 feet to the screenBuyers who want OLED picture without flagship pricing

What reviewers say

Reviewers and owners rate the C3 as one of the best value large OLEDs, praising its contrast, gaming features and clean processing. Common complaints are brightness in bright rooms and the usual OLED cautions about burn-in and glare.

What people mention
  • Picture qualityPraisedOwners call the contrast and black levels the reason to buy, especially for films in dark rooms.
  • BrightnessMixedReviewers say it is bright enough for most rooms but dimmer than the G3 and top LED-LCD sets in daylight.
  • GamingPraisedFour HDMI 2.1 ports, 4K 120Hz and VRR are cited as a big draw for console players.

Questions and answers

Is the LG C3 good for gaming?
Yes. It has four HDMI 2.1 ports with 4K at 120Hz, VRR and ALLM, plus a low-latency game mode. It is a strong match for PS5 and Xbox Series X.
How is the C3 different from the G3?
The G3 uses LG's MLA panel for higher peak brightness and a flush wall-mount design. The C3 is dimmer but has the same processor family, webOS and HDMI 2.1 features.
Do I need a soundbar with this TV?
The built-in speakers are fine for everyday viewing, but the set is thin and bass is limited. A soundbar or AV receiver improves movie sound.
Can the C3 burn in?
OLED pixels can degrade with long static images such as logos, tickers or desktop taskbars. Vary content and use the screen-off and pixel-refresh features to lower the risk.
What is in the box?
The TV, its stand, a magic remote, batteries and power cable. A wall mount and HDMI cables are sold separately.
Does it support Dolby Vision and Dolby Atmos?
Yes. It handles Dolby Vision HDR and Dolby Atmos audio, and both are supported by the major streaming apps on webOS.

  • About the LG 77" Class 4K UHD OLED Web OS Smart TV with Dolby Vision C3 Series - OLED77C3PUA

    The LG OLED evo C3 is a 77-inch class 4K UHD OLED smart TV running webOS. It is powered by the a9 AI Processor Gen6, made exclusively for LG OLED, and has a Brightness Booster for luminous picture and high contrast, even in well-lit rooms.

    AI-assisted deep learning analyzes what is on screen and chooses the picture and sound settings for that content. The TV supports Dolby Vision and HDR for picture and Dolby Atmos for sound.

    The bezel is almost invisible, so the TV blends into the background. When you are not watching, it can display paintings, photos and other content.
