Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
TechRadar measured 668 nits on a 10% HDR window in Cinema mode and 637 nits in Standard, testing the 55-inch panel directly. Full-field 100% white measured 131 nits in Cinema and 172 nits in Standard. That second pair of numbers is the one that matters and the one nobody quotes: on a snow scene, a daytime football pitch or a bright studio broadcast, this television produces roughly a fifth of the light a Mini-LED does.
What it gives you in exchange is per-pixel emissive control. There is no backlight, so there is no blooming around subtitles, no halo around a starfield, and no viewing-angle penalty at all. Contrast is effectively infinite because black pixels are simply switched off. In a controlled dark room this is a categorically different image from anything backlit, and no Mini-LED here matches it.
The connectivity is the best in this ranking. All four HDMI ports are full 48 Gbps with 4K120, VRR, ALLM, eARC and QMS. Combined with 9.1 ms measured input lag in Game Optimizer, this is the only set here where you can connect two consoles and a soundbar without compromise. webOS 25 covers the full European app set, and tuners are DVB-T2, DVB-C and DVB-S2.
Two limitations to weigh. There is no HDR10+ support — LG backs Dolby Vision only. And the screen is very reflective, which compounds the brightness problem: in a room with windows behind the seating, reflections will be visible in dark scenes. TechRadar also observed that the B5 is very similar to the previous B4, so a discounted B4 remains worth comparing on price.
The EU energy label reads class F for SDR and class G for HDR. The kWh/1000h figure was not published by any source we could verify.

Component scores
Where the score
comes from.
Four components, equal weight, each on a 0–10 scale and each resting on a named source. The overall score is their mean — the full procedure is in the methodology.
What we liked
- Per-pixel emissive black with effectively infinite contrast
- Four full-bandwidth HDMI 2.1 ports — the best connectivity here
- 9.1 ms measured input lag in Game Optimizer
- Unlimited viewing angle — no colour shift from any seat
- Dolby Vision, webOS 25, full European app coverage
- Class F SDR energy label, better than most sets here
Worth knowing
- 131-172 nits full-field — dramatically dimmer than Mini-LED on bright content
- 668 nits peak is modest even by OLED standards
- No HDR10+ support
- Very reflective screen surface
- Only 20 W built-in audio
- Very similar to the older, cheaper B4 (TechRadar)

FAQ
Frequently asked questions
Is 668 nits enough for a bright living room?
For HDR highlights in a moderately lit room, yes. For sustained bright content in direct daylight, no — the full-field figure of 131-172 nits is the relevant one, and it is roughly a fifth of what the Mini-LED sets here produce. If your television faces a window, a Mini-LED will be visibly more comfortable to watch during the day.
Should I worry about burn-in?
The mechanism is real: static high-brightness elements such as channel logos, game HUDs or news tickers displayed for thousands of hours can cause uneven wear. LG runs pixel-shifting and automatic panel-refresh cycles to counter it. We found no measured European burn-in data on 2025 panels, so we will not quote a figure. Ordinary mixed viewing is not a realistic risk; a television used eight hours a day as a static dashboard is a different case.
Is the older LG B4 a better buy?
Possibly. TechRadar's assessment was that the B5 is very similar to the B4. If the B4 is available in your market at a meaningful discount, compare the two on price rather than assuming the newer model is better.
