The verdict
A strong pick for gaming and dark-room viewing at the low end of the OLED market, with measured input lag among the best of any TV. HDR highlights are far dimmer than on the C6, and two of three reviewers saw a green cast, so anyone who can stretch to a discounted C6 gets a noticeably brighter picture. Pair it with a soundbar.
The LG B6 is the cheapest OLED in LG's 2026 range, sold in the US in 48, 65, 77 and 83-inch sizes. It pairs a WOLED panel with the Alpha 8 Gen3 processor, four HDMI 2.1 inputs with 4K 120Hz gaming, Dolby Vision and webOS 26. Lab tests found brighter HDR than the B5 and very low input lag. Reviewers also reported a green tint on their samples, a reflective screen and weak built-in speakers.
Strengths
- Brighter than the B5: Tom's Guide measured 695 nits of 10% HDR brightness (B5: 606) and TechRadar measured 835 nits in Filmmaker Mode.
- Very low input lag, measured at 8.9ms at 4K 60Hz by both Tom's Guide and TechRadar.
- Four HDMI inputs listed for 4K 120Hz, VRR and ALLM, plus HGIG and Dolby Vision gaming support.
- Tom's Guide found its out-of-the-box SDR color accuracy slightly better than the pricier C6's.
- Dolby Vision, Filmmaker Mode, AirPlay and Google Cast on webOS 26, which reviewers rated highly.
Weak spots
- HDR highlights trail the C6 by a wide margin: Tom's Guide measured 695 nits against 1,251 on the C6.
- TechRadar and What Hi-Fi both saw a green tint on their samples, and What Hi-Fi also noted raised blacks and flicker in very dark scenes.
- TechRadar found the screen prone to mirror-like reflections under room lighting.
- Thin-sounding 2.0-channel, 20W speakers with limited bass.
- No HDR10+, no DTS decoding and no ATSC 3.0 tuner, and gaming tops out at 120Hz.
- The feet sit near the edges with no central option, and Tom's Guide found them a little flimsy.
Great for
- Console gamers who want an OLED with 4K 120Hz and very low lag
- Movie watching in a dim or dark room
- Shoppers who want LG's least expensive 2026 OLED
Skip if
- Bright rooms with lamps or windows facing the screen
- Anyone who needs HDR10+ or DTS
- PC gamers who want refresh rates above 120Hz

Setup notes
- eARC is on HDMI 2.
- All four HDMI inputs are listed as supporting 4K 120Hz, VRR, ALLM, QMS and QFT.
- Two USB 2.0 ports and an optical digital audio output are included.
- HDR formats are Dolby Vision, HDR10 and HLG; HDR10+ is not listed.
- The tuner is ATSC 1.0 and ClearQAM, with no ATSC 3.0.
- The 83-inch uses a 400 x 400 mm VESA pattern; the other sizes use 300 x 200 mm.
- The two feet mount near the screen edges, so the furniture needs to be nearly as wide as the TV (LG lists a 42.1-inch stand width on the 65-inch).

An enthusiast channel's upbeat look at the B6, pitching it as the value choice in LG's 2026 OLED range.
What reviewers found
Summaries in our own words. Follow the link to read each review in full.
Tested the 65-inch and called it a superb OLED for its price. In the lab it edged the C6 on SDR color accuracy and lag, though its HDR peak was roughly half as bright. Gripes were tinny rear-firing speakers, AI extras of little use, and a wobbly two-foot stand that needs a wide console.
Read the originalMeasured clearly higher HDR brightness than the B5 and rated gaming and webOS 26 top marks. Side by side with the B5, its sample showed a stronger green tint, and the screen reflected room lights badly. At launch pricing the reviewer preferred a discounted B5 or a stretch to the C6.
Read the originalFound the 65-inch surprisingly bright for an entry OLED and well equipped for gamers, but saw greenish skin tones that its basic color controls cannot correct, plus grey-looking blacks and flicker in very dark scenes. Sound was judged average, and the default picture mode needed switching to Filmmaker Mode.

What owners are saying
From Reddit and forums, paraphrased with a link to the original discussion. Community reports are anecdotal.
An owner who moved from an LG C9 to a 48-inch B6 in 2026 reports no burn-in in their household and says OLED motion judder has not bothered them, especially in games with motion blur.
Read the originalUses a 48-inch B6 in a bedroom for news and casual viewing and calls it good rather than great: next to their Sony A95L, color and skin tones never looked as natural, whatever settings they tried.

Questions
Is the LG B6 a big upgrade over the B5?
It is brighter: Tom's Guide and TechRadar both measured more HDR brightness than on the B5. TechRadar also saw more green tint than on the B5 and preferred the older model while it remains in stock at a lower price.
What are the exact US model numbers?
OLED48B6GUA, OLED65B6GUA, OLED77B6GUA and OLED83B6GUA, all taken from LG's US product pages. LG's US site sells the 48-inch under the B6E name.
Is there a 55-inch B6 in the US?
LG's US product pages read for this listing show 48, 65, 77 and 83-inch sizes only. TechRadar lists a 55-inch B6 for the UK and Australia.
What is the difference between the B6 and the B6E?
LG told TechRadar that the B6E lacks Precision Picture Master Pro, Precision Sound Master Pro and the marble-effect back, but otherwise matches the B6, including the panel. In the US, only the 48-inch carries the B6E name.
Does the B6 support 144Hz or 165Hz gaming?
No. LG lists a 120Hz native panel with VRR up to 120Hz. The C6 and G6 support up to 165Hz for PC gaming.
