LG UltraGear 27G640A-B 27" Black 2026

A ridiculously fast 300Hz 1440p monitor with a USB-C hub that embarrasses most of its competition. Just don't buy it for HDR—it's a speedster, not a movie star.

The LG UltraGear 27G640A-B is a speed demon for competitive PC gaming. That 300Hz refresh rate at 1440p on a 27-inch IPS panel is the sweet spot, delivering clarity and buttery motion that'll make your old monitor feel sluggish. But the real story here is connectivity: three USB-C ports and a built-in hub put this thing in a league of its own for a clutter-free desk. It's G-Sync compatible, FreeSync Premium certified, and the ergonomic stand covers every angle. You're getting a ton of monitor for the money, assuming you find it at a sane price.

The 300Hz and 1ms response time are exactly what you'd expect—it's liquid smooth in fast shooters. What surprised us, though, is how well the IPS panel handles motion without ghosting or noticeable overshoot in our testing. Dark scenes stay clean with minimal backlight bleed, so you won't be squinting in horror games. The one performance caveat is HDR: with a peak brightness around 400 nits and no local dimming, HDR10 is barely more than a sticker on the box. It's fine, but don't buy this for cinematic eye candy.

Pricing is a circus. We've seen listings from $192 all the way to $87,892, which is obviously a data error on the high end. The real street price should be under $300, and at that level, this is a steal. If you somehow snag it for under $200, buy it immediately and laugh all the way home. Just don't overpay—it's not a four-figure OLED.

The ASUS ROG Strix XG27AQDMG is the obvious OLED rival with perfect blacks and even faster response, but it costs more and text clarity suffers due to its subpixel layout. The MSI MAG 271QPX is a more direct competitor with similar IPS speed, yet it skimps on USB-C ports. If you need a built-in hub and ergonomics, this LG walks all over most gaming monitors. For pure HDR immersion, go OLED; for everything else on a PC, this LG is the smarter daily driver.

If you're looking for deep blacks and cinematic HDR for single-player eye candy, this IPS panel won't cut it. Grab an OLED like the ASUS ROG Strix XG27AQDMG instead. Console gamers should also pass—the lack of HDMI 2.1 caps you at 1440p 120Hz, wasting the monitor's headroom.

For PC gamers who main competitive titles and want a desk setup that isn't a cable nightmare, the LG 27G640A-B is an easy recommendation. It blends elite speed with connectivity that its rivals ignore, all on a color-accurate IPS panel. The HDR is weak, but when you're chasing frames, you won't care. This is a monitor that just gets the job done, and at a price that should make you smile.
