LG OLED evo AI C6 42-inch TV vs LG B6E Series OLED 4K Smart TV

The B6E is the better value for most people: a 55-inch OLED at $799.99 at Best Buy as of November 7, 2026, versus $949.99 for the 42-inch C6 as of November 2, 2026. The C6 is the pick only if 42 inches is the hard limit for your room or desk, or if you want its 165Hz panel and four HDMI 2.1 ports for high-frame-rate gaming. The B6E gives you a much larger screen for less money, with a step-down processor and a 120Hz panel.

What reviewers say

LG OLED evo AI C6 42-inch TV

  • 4.7 / 5147 ratings

Owners rate the C6 highly, at 4.7 out of 5 from 147 ratings. Praise centers on picture quality, blacks and gaming features; the main complaints are about brightness in bright rooms and the small 42-inch size.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and colors are rich, especially in a dim room.
  • BrightnessMixedReviewers find it bright enough for most rooms but not for a sunlit window wall.
  • GamingPraisedThe 165Hz panel and four HDMI 2.1 ports are called out as a strong gaming package.
  • SoundCriticisedOwners say the built-in speakers are weak and a soundbar is needed for movies.

LG B6E Series OLED 4K Smart TV

Rated 4.8 out of 5 from 116 ratings, the B6E is well received. Owners focus on picture quality and gaming features rather than smart-platform extras.

  • GamingPraisedThe 120Hz panel with VRR support is called smooth for console gaming.
  • BrightnessCriticisedSome say the screen struggles in bright, sunlit rooms.

Questions and answers

Which is better for gaming, the C6 or the B6E?
The C6 wins on raw gaming specs: 165Hz and four HDMI 2.1 ports. The B6E covers 120Hz with G-Sync and FreeSync Premium, which is enough for PS5 and Xbox Series X at 4K 120. Pick the C6 only if you run a high-refresh PC setup.
Is the 55-inch B6E really cheaper than the 42-inch C6?
Yes. The B6E was $799.99 at Best Buy as of November 7, 2026, and the C6 was $949.99 as of November 2, 2026. You get 13 more inches of screen for $150 less.
Which has the better picture in a bright room?
The C6. Its evo panel with Brightness Booster Pro is rated up to 3.2x brighter than a standard OLED. The B6E uses a standard OLED panel, so it is more prone to glare and reflections in a sunny room.
Does either TV have a next-gen ATSC 3.0 tuner?
The C6 lists no ATSC 3.0 support, and the B6E lists ATSC and Clear QAM tuners only. If you rely on an antenna for 4K broadcast, neither is a safe bet.
Which lasts longer before burn-in?
Both use LG OLED panels, so burn-in risk is similar. The C6 adds OLED Care, a pixel-protection feature LG says helps retain picture quality over time. The B6E's listing does not mention an equivalent feature.
Is the C6 worth the extra $150?
Only if you need a 42-inch screen or 165Hz gaming. For movies and general streaming in a normal-size room, the B6E's larger screen and lower price make it the better buy.
