LG LG 32U631A-B 31.5" 1440p HDR 100 Hz Monitor Review

The LG 32U631A-B is a 32-inch 1440p monitor that offers great value for everyday use. It features a 100Hz IPS panel and a USB-C port, making it a solid choice for home office productivity and media consumption. Just don't expect top-tier gaming performance or professional-grade color.

If you're looking for a big, no-fuss 1440p monitor for your home office, the LG 32U631A-B is a solid contender. It's a 31.5-inch IPS screen with a 2560 x 1440 resolution, which is a sweet spot for getting a lot of screen real estate without needing a super powerful graphics card. It runs at 100Hz, which is a nice bump over the standard 60Hz for smoother scrolling, and it's priced in a very reasonable $200-$250 range. Basically, it's LG's answer to the question: 'What's a good, big monitor that won't break the bank?'

Let's talk numbers. The 100Hz refresh rate is its main performance feature, and it's a noticeable step up from 60Hz for everyday use. Everything just feels a bit smoother when you're moving windows around or scrolling through long documents. Our database puts its overall performance score right at the 50th percentile, which tells you this isn't a gaming or professional color-grading beast. That 5ms GtG response time is fine for office work and casual gaming, but competitive esports players will want something faster. The 250-nit brightness is decent for a well-lit room, but it's not going to win any HDR beauty contests, even with the HDR10 support.

For the price, it's hard to argue with what you get. In the $200-$250 bracket, you're typically looking at 27-inch 1440p monitors or basic 32-inch 1080p screens. The LG 32U631A-B gives you that bigger 32-inch canvas with the sharper 1440p resolution and that nice 100Hz bump. If you want a big screen for productivity, media, and light gaming, this monitor delivers a lot of screen for your money.

It's up against some interesting alternatives. The Dell UltraSharp 27" 4K 120Hz monitor is a more premium office-focused pick with better color accuracy and a sharper 4K screen, but it's smaller and will cost more. For a similar price, you might find 27-inch gaming monitors with higher refresh rates (like 144Hz or 165Hz), but they'll have smaller screens. Then there are the ultra-wide and massive screens like the Samsung Odyssey Neo G9 or LG UltraGear 45", but those are in a completely different price and performance league. The LG 32U631A-B carves out its niche by offering sheer size and a balanced feature set at a very accessible price point.

Skip this monitor if you're a hardcore competitive gamer—you'll want a monitor with a higher refresh rate (144Hz+) and a faster response time (1ms). Also, if you work in graphic design, video editing, or any field where color accuracy is critical, you should look at monitors with wider color gamuts and factory calibration. And finally, if your desk is in a very sunny spot, the 250-nit brightness might struggle with glare.

So, should you buy it? If your priority is a large, affordable screen for general productivity, web browsing, and casual content consumption, then absolutely. The 100Hz refresh rate is a nice quality-of-life upgrade, and the 1440p resolution on a 32-inch screen is a great fit for multitasking. But if you're a serious gamer needing high frame rates, a creative pro who needs color accuracy, or someone who works in a very bright room, you'll want to look at more specialized (and more expensive) options. This monitor knows what it is: a reliable, big-screen workhorse for your desk.
