LG C6 Series OLED TV (65") vs LG OLED42C5

The LG C6 is the better TV for most people: a 65-inch OLED with the newer Alpha 11 Gen3 processor, a 2.2-channel speaker system and four HDMI ports. The OLED42C5 is a smaller 42-inch set on the older Alpha 9 Gen8 chip, but it adds a 144Hz refresh rate and anti-glare coating that suit a desk or a bright room. Owners of both praise the OLED contrast and near-instant response time; the C6's larger panel and stronger audio make it the more complete living-room TV, while the C5 is the pick when space is tight.

  • Choose the LG C6 if you want a 65-inch OLED as the main TV in a living room, with better built-in sound and the newer picture processor.
  • Choose the LG OLED42C5 if you need a smaller 42-inch OLED for a bedroom, desk or tight wall, and you value the 144Hz panel and anti-glare screen.

What reviewers say

LG C6 Series OLED TV (65")

  • 4.8 / 5900 ratings

With 4.8 out of 5 from 900 ratings, owners are largely very happy with the C6's picture and gaming features. Complaints tend to be about brightness in bright rooms and the built-in sound rather than the panel itself.

What people mention
  • Picture qualityPraisedOwners describe deep blacks, rich color and strong contrast, especially in dim rooms.
  • GamingPraisedReviewers like the 120Hz panel, VRR and four HDMI 2.1 ports for consoles and PCs.
  • BrightnessMixedSome find it bright enough for most rooms; others say a sunlit room washes out the picture.
  • SoundCriticisedThe 2.2-channel speakers are called thin, and many buyers add a soundbar.

Questions and answers

Which is better for a bright living room?
The OLED42C5 has an anti-glare coating, which helps in a sunny room. The C6's larger panel and brighter processing still make it the stronger main TV if you can control the light.
Which is better for gaming?
The C5's 144Hz refresh rate and VRR support edge out the C6's 120Hz for high-frame-rate PC gaming. Both have near-instant response time, so console players will be happy with either.
Is the C6 worth stepping up to over the C5?
Yes if you want a 65-inch screen, better built-in sound and the newer Alpha 11 processor. The C5 makes more sense when space is limited or you sit close to the screen.
Which has better sound without a soundbar?
The C6. Its 2.2-channel, four-speaker system gives more bass and width than the C5's 2.0-channel 20W setup.
Which lasts longer?
Both are OLED panels with similar lifespans. The C6's newer processor and webOS 26 should stay current longer, while the C5's smaller panel is easier to place and less exposed to knocks.
Do both support Dolby Vision and HDR?
The C5 lists Dolby Vision, HDR10 and HLG. The C6 supports HDR, and LG's C-series OLEDs generally include Dolby Vision, so both handle major HDR formats.
