Our take on the LG UA77 Series TV UHD AI 4K Smart 55 Inch

The LG UA77 is a 55-inch 4K LED smart TV from LG's 2025 lineup, built on webOS with four HDMI ports, Dolby Vision and HDR10 support, and gaming features like ALLM and eARC. It is a plain edge-lit panel with no local dimming and no wide color gamut, so it suits everyday viewing rather than dark-room movie buffs. At $380.99 at Abt Electronics as of November 7, 2026, it sits at the low end of what a 55-inch LG typically costs, and only two stores list it new.

Questions and answers

Is the LG UA77 good for gaming?: It supports ALLM, which cuts lag when a console is detected, and eARC passes uncompressed audio to a soundbar. It has no 120Hz panel or VRR, so it suits casual play more than competitive gaming.
Does it have local dimming?: No. The UA77 is a direct-lit LED panel without local dimming, so dark scenes show gray blacks and some backlight bleed. It performs best in a bright room.
What is in the box?: You get the TV, its stand, a remote and the power cable. A wall mount is not included, though the set is VESA-compatible.
Is $380.99 a good price for this TV?: It is a low price for a 55-inch LG 4K set, and only two stores list it new as of November 7, 2026. With so few sellers, compare both before buying.
Does it support Dolby Vision?: Yes. It handles Dolby Vision, HDR10 and HLG, but without wide color gamut the HDR boost is modest compared with pricier sets.
Can I mount it on a wall?: Yes. It is VESA-mountable and flat, so a standard bracket works. Check the bracket's size rating against the TV's weight before mounting.
Where is the LG UA77 Series TV UHD AI 4K Smart 55 Inch cheapest?: At Abt Electronics, for $380.99, as of our latest check.
Where can I buy the LG UA77 Series TV UHD AI 4K Smart 55 Inch?: 2 stores we checked sell it, including Abt Electronics, Best Buy.
