The verdict
For bright rooms and mixed use, the 55 to 83-inch G6 is among the best OLEDs reviewers have tested, with a big lead over the C6 in peak brightness. Dark-room viewers may not feel the extra cost, as the gains are mostly in highlights. Treat the 97-inch as a separate product with a different panel and no independent lab data.
The LG G6 is LG's 2026 flagship OLED, sold in 55, 65, 77, 83 and 97-inch sizes with a flush wall mount supplied. The first four use a Primary RGB Tandem 2.0 panel with the Alpha 11 Gen3 processor and a Reflection Free Premium screen, and reviewers measured peak HDR brightness above 2,400 nits on the 65-inch. The 97-inch is different: it lacks the tandem panel and anti-reflection screen and tops out at 120Hz VRR.
Strengths
- Very high measured brightness: TechRadar logged 2,471 nits at a 10% window and Trusted Reviews 2,458 nits, both on the 65-inch.
- Full-screen HDR brightness of 455 nits in TechRadar's test, a large jump over the G5.
- Reflection Free Premium screen on 55 to 83-inch sizes, praised by TechRadar for handling room glare.
- Measured input lag of 8.9ms with boost on, plus 4K gaming up to 165Hz with G-SYNC Compatible and FreeSync Premium.
- Flush wall mount is supplied, and a 5-year panel warranty comes with the G-series.
Weak spots
- Premium price and no HDR10+ or DTS support, according to TechRadar.
- The 97-inch uses a much older panel, with 120Hz VRR and no Reflection Free Premium.
- Trusted Reviews noted a purple tint from the anti-glare panel and only average built-in sound.
- Some webOS apps need an account sign-up, per Trusted Reviews.
- Gains over the G5 are mostly in small highlights, so dark-room viewers may see less benefit, per Tom's Guide.
Great for
- Bright living rooms that need strong glare handling
- Gamers who want the lowest measured input lag and 165Hz
- Wall-mounted installs that want a flush fit
Skip if
- Anyone who needs HDR10+ or DTS decoding
- Buyers of the 97-inch who expect the same picture tech as smaller G6 sizes
- Dark-room-only viewers on a tight budget

LG's BEST OLED YET...? | NEW G6 OLED TV Full Review
A full review of the G6 that asks if it is LG's best OLED yet.
What reviewers found
Summaries in our own words. Follow the link to read each review in full.
Tested the 65-inch and found a large brightness jump over the G5, accurate color, very low input lag and much better reflection handling. Downsides were the premium cost and the missing HDR10+ and DTS support. Notes the 97-inch uses an older panel.
Read the originalMonth-long test of the 65-inch that called it one of the brightest OLEDs measured, with strong upscaling and gaming. Complaints included only average sound, a purple cast from the anti-glare panel, and a webOS account sign-up for some apps.
Read the originalSide-by-side with the G5, the G6 gained on peak and full-screen brightness and looked more refined, though the peak-brightness gain was incremental while the full-screen gain was large.
Read the originalA pre-review comparison based on LG's claims rather than lab tests. It expects the larger G6 sizes to use the newer tandem panel and gain mostly in small highlights and bright-room black levels, so dark-room viewers may see less benefit.

What owners are saying
From Reddit and forums, paraphrased with a link to the original discussion. Community reports are anecdotal.
An owner describes a color uniformity tint on two separate G6 panels that showed in most SDR and Dolby Vision modes but not in Game Optimizer or Dolby Vision Filmmaker. LG support offered no confirmed cause or fix, and the owner switched to another brand.
Read the originalA commenter advises steering clear of the 77-inch G6 and C6H because of banding and uniformity complaints on tandem panels, and says OLED in general is not ideal for a very bright room, though others disagree.
Read the originalA buyer picks the 77-inch G6 for its flush mount and glossy anti-reflective screen while acknowledging the panel-lottery reports, and plans to buy from a retailer with easy returns and to rely on the five-year panel warranty.

Questions
Which G6 sizes use the Primary RGB Tandem panel?
The 55, 65, 77 and 83-inch models. LG's press release gives Hyper Radiant Color Tech to every G6 except the 97-inch, and TechRadar says the 97-inch uses a much older panel.
What are the exact US model numbers?
OLED55G6WUA, OLED65G6WUA, OLED77G6WUA, OLED83G6WUA and OLED97G6WUA. The WUA models are sold with a wall mount supplied.
Does the G6 come with a stand?
LG lists the US models as 'with Supplied Wall Mount'. The product pages still print with-stand dimensions, but LG's page does not say whether a stand is sold or included.
How much brighter is the G6 than the C6?
On the 65-inch, TechRadar measured about 2,471 nits at a 10% window for the G6, against 1,438 nits for the C6 at the same size. The 97-inch is not the tandem panel and has no independent measurement.
Does the G6 support HDR10+?
No. LG lists Dolby Vision, HDR10 and HLG, and TechRadar notes the missing HDR10+ and DTS support.
