Our take on the LG OLED42C5PUA 42" 4K Ultra HDR Smart OLED Evo TV

The LG C5 is a 42-inch 4K OLED Evo TV built on LG's self-lit OLED panel, so each pixel turns on and off on its own for true blacks and near-infinite contrast. It runs webOS with the major streaming apps, supports HDR formats including Dolby Vision, and has four HDMI 2.1 ports with 4K 120Hz and variable refresh rate for consoles and PCs. At 42 inches it is one of the smallest OLED TVs sold, which suits a bedroom, desk or small living room where a larger panel would overwhelm the space. Against LCD rivals it wins on contrast and viewing angles but gives up some peak brightness in a bright room, and its panel is dimmer than the larger C5 sizes.

What reviewers say

Owners and reviewers rate the 42-inch C5 as the best small OLED TV for mixed film and gaming use, praising its contrast, gaming features and webOS. Complaints center on brightness in bright rooms, reflections and the usual OLED burn-in caution.

What people mention
  • Picture contrastPraisedOwners say the self-lit panel delivers deep blacks and punchy contrast that LCD TVs in this size cannot match.
  • BrightnessCriticisedReviewers note peak brightness is limited, so HDR highlights and daytime viewing look flatter than on brighter LCD sets.
  • GamingPraisedPlayers praise the four HDMI 2.1 ports, 4K 120Hz support and low lag for consoles and PCs.

Questions and answers

Is the LG C5 42-inch good for gaming?
Yes. It has four HDMI 2.1 ports with 4K 120Hz, variable refresh rate and auto low-latency mode, which covers PS5, Xbox Series X and most gaming PCs.
How is it different from the C4?
The C5 is the newer generation with a brighter OLED Evo panel and updated webOS and processing. The step up is modest, so a discounted C4 remains a reasonable alternative.
Is 42 inches too small for a living room?
It suits bedrooms, desks and small rooms. For a main living room with seating several feet back, most viewers prefer 55 inches or larger.
Does it support Dolby Vision and Dolby Atmos?
Yes. It handles Dolby Vision HDR and Dolby Atmos passthrough, though the built-in speakers cannot produce real overhead Atmos sound.
Should I worry about OLED burn-in?
Static logos, news tickers and game HUDs left on for long periods can leave marks over years. 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 a power cable. A wall mount and HDMI cables are not included.
