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 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.

The field just got a lot more interesting. The MSI MPG 271QR QD-OLED X50 is the new hotness with quantum dot colors and true blacks that make this LG's IPS panel look washed out in dark rooms, but you'll pay a premium and still deal with that subpixel text fuzz. The ASUS ROG Strix XG27UCDMG is a 4K monster that outclasses this 27-incher in raw sharpness, though it demands a beefier GPU to push those pixels at high refresh. Samsung's Odyssey G60SD brings OLED contrast to the table with a glossy finish that makes colors pop, but it's pricier and lacks the USB-C hub that makes this LG so practical. For pure competitive speed and a clean desk, this LG still holds its own against the newcomers, but the QD-OLED from MSI is the one that should make you pause if you can stretch your budget.

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 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.

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.
