LG BN70U 43BN70U-B 43" Matte Black 2019

The LG 43BN70U-B lands in the 96th percentile for display size and the 98th percentile for connectivity, making it a fantastic multi-device productivity hub. But its 61Hz refresh rate and 8ms response time are among the slowest we've seen, putting it in the 7th percentile for performance. Buy it for the massive 4K canvas and the four HDMI ports, not for gaming or smooth motion.

Let's be upfront: the 43BN70U-B is one of the slowest panels we've seen for motion handling, landing in the 7th percentile for performance. The 61Hz refresh rate and 8ms response time mean you'll see noticeable blur in fast-moving content. Scrolling through long documents or web pages won't feel as crisp as it does on a 120Hz+ display. But that's not what this monitor is for. It's built for static productivity, spreadsheets, coding, and video playback where the 4K resolution shines.

Where it does well is in color and clarity. The 10-bit panel supports 1.07 billion colors, and the 72% NTSC coverage puts it in the 78th percentile for color, which is strong for a non-professional display. The 350-nit brightness is about average, so it's fine for most indoor environments but might struggle near a bright window. The 1000:1 contrast ratio is standard for IPS, meaning blacks won't be as deep as on a VA or OLED panel, but you get the wide viewing angles IPS is known for.

Stacked against the competition, the LG 43BN70U-B plays a completely different game. The ASUS ROG Strix XG27UCDMG and MSI MAG 271QPX are 27-inch 4K OLEDs built for speed with 240Hz+ refresh rates and near-instant response times. They'll run circles around the LG in gaming and motion clarity, but they can't touch its screen size or input count. The Samsung Odyssey G60SD and Gigabyte M Series OLED MO27U2 are similarly focused on high-refresh gaming. The Apple Studio Display XDR is closer in spirit as a productivity monitor, but it's a 27-inch 5K panel with a much higher price tag and far fewer ports. The LG is in a niche of its own: a giant, slow, hyper-connected 4K canvas that's more about multitasking than any single performance metric.

At $1210, the LG 43BN70U-B is a tough sell if you're comparing it to the latest 4K OLED gaming monitors that are faster and more vibrant for similar money. But you're not buying this for speed. You're buying it for the sheer size and the port selection. Finding another 43-inch 4K IPS monitor with four HDMI ports, DisplayPort, and USB-C with power delivery is surprisingly hard. For a conference room display or a command center for a multi-device desk, the price per inch and per port actually makes sense. Just know that a chunk of your money is going toward that connectivity, not toward image quality or responsiveness.

The LG 43BN70U-B is a massive 43-inch 4K IPS display that's all about screen real estate and connectivity, not speed. Its display size and resolution land it in the 96th percentile of our database, which means you're getting a desktop canvas that's among the largest we track. The port selection is a standout too, sitting in the 98th percentile with four HDMI ports, DisplayPort, and USB-C. But the performance numbers tell a different story. A 61Hz refresh rate and 8ms response time put it in the 7th percentile, so this is strictly a productivity and content monitor, not a gaming panel.

At $1210, you're paying for that expansive 4K IPS panel and the sheer number of ways you can plug things into it. The color coverage is solid at 72% NTSC, which is well above average, but the 350-nit brightness is just okay for a well-lit room. This is a monitor built for multitaskers who want to replace a dual-screen setup with one giant display, and it delivers on that promise with built-in speakers and PIP/PBP modes. Just don't expect it to be portable at nearly 35 pounds, or to wow you with buttery smooth motion.

Gamers and anyone sensitive to motion blur should steer clear. The 7th percentile performance ranking means this is one of the slowest monitors we've tested for refresh rate and response time. If you're used to a 120Hz or 144Hz display, the 61Hz panel will feel sluggish even just scrolling through web pages. You'd be much happier with a 4K OLED like the MSI MAG 271QPX or a high-refresh IPS panel if you split your time between work and play.

The LG 43BN70U-B is a purpose-built monitor that knows exactly what it is and isn't. If you need one giant screen to replace a dual-monitor setup and you regularly switch between multiple computers, laptops, and streaming devices, the connectivity here is best-in-class. The 4K IPS panel is sharp and color-accurate enough for office work and content consumption. But if you care even a little about gaming or smooth scrolling, look elsewhere. This is a productivity panel through and through, and it earns its keep by being a versatile hub for your devices, not by being fast.
