LG UltraGear 27GN800-B 27" Black 2021

The 27GN800-B delivers 99% sRGB color accuracy at the 90th percentile, paired with a 144Hz refresh rate and 1ms response time. That's a killer combo for the USD 380 low-end price. But the 3.9/5 customer rating and polarizing anti-glare finish mean it's not a slam dunk for everyone.

The 27GN800-B runs at 2560 x 1440 with a 144Hz refresh rate and a 1ms GtG response time. That's the sweet spot for competitive gaming without needing an RTX 4090 to push frames. The 75th percentile performance ranking puts it above average, but it's not going to hang with the 240Hz and 360Hz panels out there. For most people, 144Hz at QHD is where the price-to-smoothness ratio peaks.

G-Sync compatibility plus FreeSync Premium means you're covered whether you're on team green or team red. The 10-bit color (8-bit + FRC) and HDR10 support sound nice on paper, but at 350 nits brightness, HDR is more of a checkbox than a feature. You'll get a slight boost in color depth, but don't expect OLED-level contrast or eye-searing highlights. The IPS panel delivers solid viewing angles and that 90th percentile color accuracy, which is the real performance win here.

Stacked against the competition, the 27GN800-B is fighting an uphill battle. The ASUS ROG Strix XG27UCDMG and MSI MAG 271QPX QD-OLED E2 both bring OLED panels with dramatically better contrast and HDR performance, though they'll cost you significantly more. The Samsung Odyssey G60SD offers similar specs with a more refined anti-glare treatment that doesn't sparkle like some users report here. The Gigabyte MO27U2 and Alienware AW2725D push higher refresh rates for competitive players. Where the LG wins is color accuracy per dollar, that 90th percentile sRGB coverage at the USD 380 price point is genuinely hard to beat. But if HDR matters to you, any OLED competitor will embarrass this panel.

Pricing is all over the place depending on where you shop. In the US, you'll find it anywhere from USD 380 to USD 540 across three listings, a USD 160 spread that's worth paying attention to. The cheapest US listing is the obvious move if you're stateside. Canadian buyers face a similar situation with prices ranging from CAD 562 to CAD 704. At the low end, this monitor is a solid deal for a 1440p 144Hz IPS panel with this color performance. At the high end, you're creeping into territory where better options start appearing. Shop around before you commit.

The LG UltraGear 27GN800-B hits 144Hz at 1440p on an IPS panel, and that combo lands it in the 75th percentile for performance in our database. Color accuracy is the real story here, 99% sRGB coverage puts it at the 90th percentile, which is frankly better than a lot of monitors twice the price. You're getting a 27-inch QHD panel with a 1ms response time and both G-Sync and FreeSync Premium support for smooth frames without tearing.

But the customer rating tells a different story. 3.9 out of 5 across 17 reviews isn't terrible, but it's not glowing either. The social proof sits at the 35th percentile, meaning buyers aren't exactly shouting from the rooftops about this one. Some love the panel quality and color depth, while others can't stand the anti-glare coating. It's a monitor with a great spec sheet and a polarizing real-world experience.

If you're sensitive to screen coatings, skip this one. The anti-glare finish has drawn strong negative reactions from some owners who describe it as sparkly and uncomfortable to look at. HDR enthusiasts should also look elsewhere, 350 nits won't cut it. And if you're a competitive esports player chasing every frame, the 144Hz cap and 75th percentile performance ranking mean faster panels exist. The 35th percentile social proof suggests this monitor hasn't built the reputation that some competitors enjoy.

The LG UltraGear 27GN800-B is a color-accurate 1440p gaming monitor that nails the fundamentals at a reasonable price. The 90th percentile color performance and 144Hz refresh rate make it a strong choice for gamers who also do creative work. But the 3.9/5 customer rating and complaints about the anti-glare coating suggest you should try to see one in person before buying. If you can snag it at the USD 380 end of the price range, it's a solid value. At USD 540, you're paying too much for a monitor with this many compromises.
