The 30-Second Version

The LG B4's gaming performance is in the 98th percentile, making it one of the best gaming TVs on the market with a 0.1ms response time and four HDMI 2.1 ports. You get that gorgeous OLED contrast and perfect blacks, but the picture processing is a weak spot, landing in the 36th percentile. Shop carefully because prices swing wildly from $900 to over $1400, and at the low end, it's an incredible value.

The Word on the Street

4.5/5 (448 reviews)
👍 Owners consistently rave about the stunning OLED picture quality, calling it a clear and vibrant upgrade that feels premium without a flagship price.
🤔 A few users find the new webOS interface a bit confusing to navigate at first, especially when coming from older or different TV brands.
👎 A small number of buyers have reported reliability issues, with one noting a complete failure where the TV would no longer power on.

Performance

Gaming is where this TV absolutely sings. We're talking a 98th percentile ranking in our database, putting it in the same conversation as dedicated gaming monitors that cost nearly as much. The native 120Hz refresh rate, combined with a near-instant 0.1ms response time, means motion is buttery smooth with zero perceptible blur. Having four full-bandwidth HDMI 2.1 ports is a huge flex. You can plug in a PC, PS5, and Xbox Series X simultaneously and get 4K at 120Hz with VRR on all of them. FreeSync Premium and G-Sync compatibility seal the deal, making this a top-tier choice for tearing-free gameplay.

For everyday watching, the self-lit OLED pixels do the heavy lifting. The contrast is effectively infinite, so dark scenes in a show like 'House of the Dragon' look stunning with no backlight bleed. The a8 AI Processor 4K handles auto-adjusting settings based on content, which is handy, but it's not the sharpest tool in the shed for upscaling low-resolution cable or grainy YouTube videos. That's the main reason its picture quality score lands in the 36th percentile. It's a champ with high-quality 4K HDR content, but it doesn't polish up older stuff as well as a Sony with its advanced processing. HDR formats are well-covered with Dolby Vision, HDR10, and HLG, landing it in the 88th percentile for HDR support.

vs Competition

Stacked against the Sony BRAVIA XR A95L, the B4 is the clear winner for gamers on a budget. The Sony has vastly superior picture processing and brightness, but it costs several times more. The B4 gives you 95% of the gaming experience for a fraction of the price. Compared to the Samsung Neo QLED QN800D, it's a contrast showdown. The Samsung gets much brighter and has better upscaling, but it can't touch the B4's per-pixel lighting and perfect blacks in a dark room. The TCL QM7K Series is the real threat here. It's a mini-LED TV that gets significantly brighter for HDR pop and often costs less, making it a better pick for a bright living room. The B4 fights back with superior viewing angles, that instant OLED response time, and a more refined gaming feature set with Dolby Vision gaming at 120Hz, which the Samsung lacks.

Value & Pricing

Pricing on this set is all over the map, with a spread of $523 between vendors, ranging from $900 to $1423. At the low end of that range, this TV is an absolute steal for a 55-inch OLED with this gaming feature set. You're getting a 98th percentile gaming experience for a price that undercuts many high-end LCDs. The value sweet spot is clearly at that sub-$1000 mark. If you're seeing it closer to $1400, you should probably hold off or look at a step-up model like the LG C4, which will give you a brighter panel and a better processor for a similar price. Shop around and don't pay the premium.

Overview

The LG B4 lands in the 98th percentile for gaming, which makes it one of the absolute best TVs you can buy right now if you've got a PS5 or Xbox Series X hooked up. That 0.1ms response time and 120Hz panel with full HDMI 2.1 support across all four ports is the real deal. It's not just a gaming monitor in a big screen's body either. The OLED panel delivers those perfect blacks and a 100% color volume that makes movies and shows look fantastic, even if its overall picture quality score sits at a middling 36th percentile due to some processing limitations compared to pricier sets.

But let's be real about what you're getting here. This is LG's entry-level OLED for 2024, powered by the a8 AI Processor 4K instead of the fancier chips in the C4 or G4. That means you're trading some peak brightness and upscaling polish for a much friendlier price tag. The smart platform is solid but not class-leading, the built-in 40W speakers are just okay, and you'll want to keep this thing planted on its stand because portability is its weakest score by a mile. Still, for pure gaming prowess and that inky OLED contrast, the value proposition is seriously strong.

Common Questions

Q: Is this TV good for PS5 and Xbox Series X gaming?

Absolutely. It's one of the best. With a 98th percentile gaming score, you get 4K at 120Hz on all four HDMI 2.1 ports, support for FreeSync Premium and G-Sync, and a lightning-fast 0.1ms response time. This means you can run your console at its max potential with buttery smooth motion and no screen tearing.

Q: How does the picture quality compare to a higher-end OLED like the LG C4?

The B4 uses the a8 AI Processor 4K, which isn't as powerful as the chip in the C4. This mainly affects upscaling of lower-resolution content and peak HDR brightness. The B4's overall picture quality score sits in the 36th percentile, meaning it's not the best at polishing older or low-quality video. However, with native 4K HDR content, the contrast and color volume are still phenomenal and true to OLED's strengths.

Q: Does the built-in audio system sound good enough?

It's a 2.0 channel, 40W system that ranks in the 61st percentile, which is firmly average. It gets the job done for casual TV watching and news, but it lacks the bass and immersive soundstage for movies and games. You'll definitely want to budget for a soundbar, especially since it has eARC for easy connection to a Dolby Atmos system.

Who Should Skip This

Skip the B4 if your room gets a lot of natural light. This OLED panel doesn't get bright enough to fight intense glare, and its picture quality score in the 36th percentile is partly due to its limited peak brightness compared to QLED or mini-LED sets. If you watch a lot of cable TV, standard-def content, or heavily compressed YouTube videos, the a8 processor's mediocre upscaling will be noticeable. A bright living room warrior like the TCL QM7K or a Sony with its superior processing would be a much better fit for those scenarios.

Verdict

If gaming is your primary hobby and you want the best possible picture for movies in a dark room without selling a kidney, the LG B4 is a knockout. The 98th percentile gaming score isn't just a number. It translates to a real, tangible advantage in responsiveness and smoothness that you'll feel in every match. Just know what you're trading away: top-tier brightness and the best video processing. For a mixed-use living room with lots of daytime viewing, a bright mini-LED alternative might serve you better. But for a dedicated gaming den or a light-controlled home theater on a budget, this is one of the easiest recommendations we can make right now.
