Our verdict
The LG B6 gets the fundamentals right. It is an OLED TV: each pixel makes its own light and can switch fully off, so dark scenes look properly black. All four HDMI ports support 4K at 120Hz, and the screen refreshes at up to 120Hz natively, which suits a PS5, Xbox Series X or gaming PC. It also supports Dolby Vision, HDR10 and HLG. What holds it back is price. At £1,899.99 for 65 inches, rival high-end TVs can cost about the same, and they are brighter and have better speakers. The B6 has 20W 2.0-channel sound and lower peak brightness than the C6 or G6, so it needs a clear discount.
Buy it if
- The price falls clearly below LG's C-series OLED TVs
- You have several modern consoles and want them all on 4K 120Hz ports
- You mainly watch in moderate or low light
Skip it if
- A rival high-end TV with a brighter picture and better speakers costs the same
- Daytime brightness matters, for example a room with large windows
- You want strong built-in sound
How it would fit your home
A console living room
Four HDMI ports that support 4K at 120Hz mean a PS5, an Xbox and a PC can stay plugged in, with VRR to keep motion smooth.
Evening viewing
OLED contrast gives dark films and drama convincing depth in a dimmed room.
Paying full price
At £1,899.99 the B6 has little price gap to higher models, so this is poor timing to buy.
The details, in plain English
Picture quality
The B6 uses LG's Alpha 8 AI Processor 4K Gen3 with an OLED screen. Because each pixel lights itself, blacks are deep and viewing angles stay consistent, so the picture holds up from the side of a sofa. It supports Dolby Vision, HDR10 and HLG, the main HDR formats (HDR keeps detail in both bright and dark parts of a scene). It will not reach the same highlight brightness as the C6 or G6. In a shaded room that matters less. Beside large windows it matters more.
Gaming and motion
The screen refreshes up to 120 times a second (120Hz), which is what current consoles output at their smoothest. All four HDMI ports are listed with 4K 120Hz, eARC, VRR (variable refresh rate, which stops tearing when frame rates dip) and ALLM (automatic game mode), and G-Sync and FreeSync are both supported. That is friendlier than many entry TVs, which often give only one or two full-speed ports. Consoles do not need more than 120Hz, so the B6's ceiling is no disadvantage for PlayStation or Xbox owners.
Sound
The speakers are 20W in a 2.0-channel layout, meaning two speakers and no dedicated bass unit. That is fine for news and ordinary programmes, but not for cinema. LG lists Dolby Atmos support, though small speakers cannot create the height effect of a real Atmos setup. One of the HDMI ports also supports eARC, the connection that sends full-quality sound to a soundbar, which makes adding one easy.
Living with it
LG lists webOS 26 and says security updates are supported until 31 December 2030. webOS is LG's menu system for streaming apps, casting and accessibility settings. OLED suits mixed viewing well, but continuous static information, such as a news ticker left on for hours, is better suited to an LCD TV with a backlight, because OLED screens can keep faint marks from long-running static images.
Strengths and drawbacks
What it does well
- OLED picture: deep blacks, consistent viewing angles and natural film contrast
- Four HDMI ports that support 4K 120Hz, so several consoles fit at once
- Up to 120Hz with variable refresh rate, G-Sync and FreeSync compatibility for smoother games
- Supports Dolby Vision, HDR10 and HLG
- LG's webOS menus with wide app support
What to watch out for
- The current price is too close to better models
- Lower peak brightness than the C6 and G6, which matters beside large windows
- Only 20W 2.0-channel speakers, so an add-on soundbar is likely
- Only a one-year general guarantee is listed
Samsung's S85H is another entry OLED with a launch-price problem, and brighter LCD TVs suit daytime rooms better. The B6 becomes a rational buy only when discounted below those choices.

Sonos Beam (Gen 2) Reviewed by us
A reviewed dialogue-focused soundbar can address the named weak built-in sound. Judge voices at your normal volume and include its cost before choosing the TV.
Check first: No separate bass box included; use compatible TV ARC/eARC or the manufacturer’s optical adapter. Confirm the TV’s exact outputs and plan the occupied HDMI socket.
