Our take on the LG Evo C4 42" 4K Ultra HDR Smart OLED WebOS TV

The LG C4 is a 42-inch 4K OLED TV built on LG's Evo panel, with the Alpha 9 processor, webOS smart platform and support for Dolby Vision and Dolby Atmos. Its main draw is OLED contrast: per-pixel dimming gives true blacks and wide viewing angles that LED rivals cannot match. At 42 inches it is one of the few small OLEDs, which suits bedrooms, dens and desks as much as living rooms. Reviewers consistently rate the C4 line for picture quality and gaming features, while noting OLED brightness trails the brightest Mini-LED sets in a sunlit room.

Questions and answers

Is the LG C4 good for gaming?
Yes. It has four HDMI 2.1 ports, supports 4K at 120Hz with VRR, and has low input lag, which suits PS5 and Xbox Series X.
How is it different from the C3?
The C4 uses a brighter Evo panel and a newer Alpha 9 processor with better upscaling and processing. The step up is modest, so a discounted C3 is still close.
Do I need a soundbar?
The built-in speakers are fine for everyday TV but thin for films. Most owners add a soundbar or use Dolby Atmos over eARC.
Is 42 inches too small?
It suits bedrooms, dens and desk setups where you sit close. For a large living room with seating several feet back, a 55-inch or larger set is more immersive.
Does it support Dolby Vision and Atmos?
Yes. It handles Dolby Vision HDR and Dolby Atmos audio, and webOS includes the major streaming apps.
Should I worry about burn-in?
OLED can retain static images over long periods. Vary content, avoid leaving news tickers or game HUDs on for hours, and use the TV's screen-care settings.
