The verdict
The B5 suits a dim or controlled room, where its perfect blacks and fast gaming response matter more than peak brightness. Both lab testers measured roughly 630 to 670 nits on a 10% HDR window, well under the C5, so buyers with a bright living room should step up or look at Mini LED. At a discounted price it is a strong OLED value; anyone who already owns a B4 has no reason to switch.
The LG B5 is the 2025 entry point to LG's OLED range, sold in 48, 55, 65, 77 and 83 inches and replaced by the B6 in 2026. It pairs a standard WOLED panel with the Alpha 8 Gen2 processor, webOS 25 and four HDMI inputs that LG lists for 4K 120Hz. Reviewers praised its color and gaming speed but measured modest HDR brightness and called the screen reflective. It is a close copy of the 2024 B4.
Strengths
- Deep OLED blacks and good color: Tom's Guide measured an out-of-the-box Delta-E of 1.65 and near-complete P3 coverage.
- Very low measured input lag, 9ms to 9.1ms in Boost mode in two separate labs, plus four HDMI inputs listed for 4K 120Hz, VRR and ALLM.
- Dolby Vision, HDR10 and HLG are supported, along with AirPlay 2, Google Cast and webOS 25.
- Five screen sizes from 48 to 83 inches, including a 48-inch option that suits desks and bedrooms.
- Tom's Guide and TechRadar both found the picture strong for the entry-level class.
Weak spots
- HDR brightness is modest: about 630 to 670 nits on a 10% window in two labs, roughly half of what the C5 reached in TechRadar's tests.
- Tom's Guide called the screen highly reflective, which hurts daytime viewing.
- Almost no upgrades over the 2024 B4, apart from the webOS 25 software.
- Built-in sound is average, from a 2.0-channel speaker system.
- No HDR10+ or ATSC 3.0 tuner, and LG lists no DTS decoder.
- Superseded by the 2026 B6.
Great for
- Dim or light-controlled rooms
- Console gamers on a budget who want 4K 120Hz
- Shoppers wanting a first OLED at a sale price
Skip if
- Bright, sunlit living rooms
- Anyone who already owns a B4
- Viewers who want HDR10+

LG OLED B5 4K Smart TV: 1 Month Later Review
An owner-style follow-up covering the B5 after a month of use, per its title.
LG B5 OLED 55 Inch Review | Stunning OLED 4K Smart TV with Dolby Vision & Atmos!
A review of the 55-inch B5, focused on the picture, Dolby Vision and sound features named in its title.
What reviewers found
Summaries in our own words. Follow the link to read each review in full.
Found the B5 a decent but unspectacular OLED. Color, webOS, the remote and gaming were strengths, while lab brightness was low even for HDR, the screen was very reflective, and little had changed from the B4.
Read the originalRecommended the B5 for its contrast-rich picture and gaming, and gave it top marks for gaming and value. Reservations were its near-identical spec to the B4, average brightness and average sound. It also described an Xbox Dolby Vision workaround.

What owners are saying
From Reddit and forums, paraphrased with a link to the original discussion. Community reports are anecdotal.
A B5 owner says live sports from a low-bitrate streaming service still look good on the set, while acknowledging it would not match a pricier G-series for sports.
Read the originalA buyer who returned B5 units after problems says they were not as bad as the Samsung issue they later faced, but gives no detail, so this is only a weak signal about unit-to-unit quality.

Questions
Is the LG B5 still worth buying now that the B6 is out?
For a dim room it can be, particularly at a discount, since TechRadar found it nearly identical to the 2024 B4 and its brightness is middling. Check current prices before choosing between it and the newer B6.
What are the exact US model numbers?
OLED48B5PUA, OLED55B5PUA, OLED65B5PUA, OLED77B5PUA and OLED83B5PUA, all taken from LG's US product pages.
How bright is the B5?
Tom's Guide measured 632 nits and TechRadar measured 637 to 668 nits on a 10% HDR window of the 65-inch. Both labs described this as low for a modern OLED.
Is the B5 good for gaming?
Yes. Both labs measured input lag around 9ms in Boost mode, and LG lists 4K 120Hz, VRR, ALLM and Game Optimizer on all four HDMI inputs. It tops out at 120Hz, unlike the 144Hz or 165Hz of the pricier C5 and G5.
Does the B5 have an ATSC 3.0 tuner?
No. LG lists an ATSC 1.0 antenna tuner and a cable QAM tuner.
