LG B4 4K OLED TV vs LG C6 OLED evo 4K TV

The C6 is the better TV. Its Alpha 11 processor, Brightness Booster Pro and brighter OLED evo panel give it visibly stronger HDR highlights and better handling of bright rooms, and owners rate it very highly. The B4 is the sensible pick if you want a large OLED for a dark room and don't need the extra brightness or the newer chip. Both are 120Hz OLEDs with four HDMI 2.1 ports and Dolby Vision, so gaming and movie basics are close.

  • Choose the LG B4 if you want the biggest OLED screen you can get and mostly watch in a dim room, where its picture holds up well.
  • Choose the LG C6 if you want the brightest, sharpest LG OLED picture and the newer processor, and a 42-inch size suits your room.

LG B4 4K OLED TV

  • 4.7 / 52,000 ratings

Owners and reviewers treat the B4 as the value pick in LG's OLED line. They praise the picture, gaming features and price-to-performance, and note it is dimmer and less polished in processing than the C4.

What people mention
  • BrightnessMixedReviewers say it is bright enough for dark rooms but trails the C4 in highlights and daylight viewing.
  • Picture qualityPraisedOwners highlight deep blacks, strong contrast and accurate colors out of the box.
  • GamingPraisedFour HDMI 2.1 ports, VRR and low lag make it a favorite for PS5 and Xbox owners.
  • SoundCriticisedThe 20W 2.0 speakers are described as thin, with little bass.

Questions and answers

Which is better for a bright living room?
The C6. Its OLED evo panel with Brightness Booster Pro fights glare and keeps highlights punchy. The B4 is dimmer and looks its best in a darker room.
Is the C6 worth stepping up to over the B4?
Yes if brightness and picture processing matter to you. The Alpha 11 chip and brighter panel are real gains. If you watch mostly at night and want a big screen, the B4 is enough.
Which is better for gaming?
They are close. Both do 4K at 120Hz with VRR and ALLM across four HDMI ports. The C6's brighter panel makes HDR games pop more.
Which lasts longer?
Both are OLEDs with similar panel life. The C6 adds OLED Care features that help protect the display over time, which is a small edge for long ownership.
Do both support Dolby Vision?
Yes. The B4 lists Dolby Vision, HDR10 and HLG, and the C6 supports Dolby Vision as well. Dolby Atmos is handled on both through the TV's audio processing.
Which has better sound out of the box?
The C6. The B4 uses a basic 20W 2.0 system. Either way, a soundbar improves both for movies.
