LG B4 OLED review roundup: The honest buying verdict
What Hi-Fi? says it "looks like all the OLED TV that most people will ever need."
No single aggregate score — here's what the reviewers agree on, below.
The short version
Critics report that the LG B4 delivers the deep blacks, vibrant color and gaming features people want from an OLED without moving up to LG's more expensive models. Four HDMI 2.1 ports and a 120Hz panel make it especially appealing for console gaming. The honest trade-off is brightness and sound: the C4 is brighter, while the B4's speakers are consistently described as middling.
What reviewers loved
- OLED black levels and pixel-level contrast give movies and games rich, high-impact images.
- Four HDMI 2.1 ports support 4K/120Hz, VRR and ALLM, making the B4 unusually flexible for multi-console setups.
- Tom's Guide reports a low 9.7ms input latency, while TechRadar gives its gaming performance 5/5.
- Reviewers praise its vibrant colors, strong motion processing and detailed picture.
- webOS 24 has a streamlined interface and useful Quick Cards for organizing apps.
What held it back
- Brightness is limited compared with the step-up LG C4, which matters most in brighter rooms and for HDR impact.
- Built-in sound lacks bass and spaciousness, so a soundbar is a sensible addition.
- Tom's Guide found the screen reflective, despite TechRadar noting an anti-reflection treatment.
- There is no HDR10+ support or ATSC 3.0 tuner.
Buy it if you want affordable OLED picture quality and four full-featured HDMI 2.1 connections for gaming.
Skip it if you need stronger brightness for a sunny room, better built-in audio or HDR10+ support.
What the reviewers say
TechRadar calls the B4 a high-value entry-level OLED and praises its very good picture, streamlined webOS 24 interface and feature-packed gaming support. Its biggest reservations are limited brightness and merely passable sound, with the brighter C4 complicating the value argument when prices are close.
Tom's Guide similarly highlights deep blacks, brilliant colors, motion processing and four HDMI 2.1 ports. What Hi-Fi?'s early hands-on found the B4 close to the C4 in color, detail and OLED contrast, but stressed that its session was brief and used LG demo material. RTINGS also publishes an independent review and a dedicated settings guide.
The competition
LG C4 OLED
The step-up option offers a substantial brightness advantage. The B4 remains the better-value choice when the price gap is large.
Should you buy it?
Yes, if value and gaming matter more than maximum brightness. Across the supplied reviews, critics agree that the LG B4 preserves OLED's core strengths while adding four HDMI 2.1 ports and strong 120Hz gaming support. The weak speakers are easy to fix with a soundbar, but the brightness ceiling is permanent, so compare its price with the brighter LG C4 before buying.
