LG UltraGear LG UltraGear G8 27" DUAL MODE UHD 4K 240Hz Full HD Review

The LG UltraGear G8 27G850A-B is a performance powerhouse, scoring in the 97th percentile. Its killer feature is dual-mode refresh: stunning 4K at 240Hz or super-responsive 1080p at 480Hz. With elite color accuracy and full adjustability, it's a near-perfect all-rounder for a fixed desk, though its size and weight mean it's staying put.

The LG UltraGear G8 27G850A-B is a monitor that doesn't just want to be good, it wants to be top of the class. It lands in the 97th percentile for performance and ergonomics, and the 98th for color. That means it's faster and more adjustable than almost everything else we've tested. The headline is its dual-mode trick: 4K at 240Hz for sharp detail, or dropping to 1080p for a blistering 480Hz refresh rate. You're getting a display that's built to handle both high-resolution eye candy and ultra-competitive frame chasing.

It's not just a gaming screen, though. Our scoring puts it at a 93.9 for office work and 93.2 for professional use, thanks to that stellar color accuracy and IPS Black panel for deep contrast. The trade-off is obvious: at nearly 9.4kg and scoring in the 28th percentile for compactness, this is a desktop anchor. It's built for a permanent, premium setup.

Let's talk numbers. A 240Hz refresh rate at 4K is still rare, and this monitor's performance score sits in the 97th percentile for a reason. That 1ms GtG response time and G-Sync/FreeSync Premium Pro support mean motion looks incredibly smooth. The dual-mode feature is the real party trick. If you're playing a competitive shooter where every millisecond counts, you can switch to 1080p and get a 480Hz signal. That's a niche, hyper-responsive mode you won't find on many displays.

The IPS Black panel delivers a 2000:1 contrast ratio, which is noticeably better than standard IPS screens. With 99% DCI-P3 coverage (98th percentile for color) and HDR10 support, games and media look vibrant and rich. Brightness is solid at 450 nits, making HDR content pop. This is a display that excels in both the 'wow' factor and the hardcore specs.

Priced between $545 and $597, the LG UltraGear G8 sits in a interesting spot. For a 27-inch 4K 240Hz monitor with this level of color accuracy and adjustability, that's actually competitive. You're paying a premium for that dual-mode high-refresh-rate capability and the IPS Black tech. When you compare it to larger, more expensive mini-LED or OLED competitors, this monitor offers a more balanced, all-purpose package at a lower price point, especially if your desk real estate maxes out at 27 inches.

Stacked against the competition, the G8's strength is its balance. The Samsung Odyssey Neo G9 57-inch is a beast with more screen, but it's a different category of size and cost. The ASUS ROG Swift 32" QD-OLED will have perfect blacks and faster response, but it's larger, more expensive, and you trade the risk of burn-in for that perfect contrast. The MSI MPG 32" 4K 240Hz is a closer match spec-wise but on a bigger VA panel, and the Dell UltraSharp 27" 4K 120Hz is more of a productivity-focused display. The LG G8 carves its niche by offering top-tier 27-inch gaming performance, professional-grade color, and that unique high-refresh dual-mode flexibility in one well-built package.

Skip this if you need a portable monitor or have a tiny desk. It scores in the 28th percentile for compactness and weighs over 9kg, so it's a permanent fixture. Also, if your budget is tight and you only care about, say, 144Hz 1440p gaming, there are cheaper options that will still feel great. This is for the user who wants the top-tier specs and is willing to pay for them.

If you want a single 27-inch monitor that can genuinely do it all—competitive gaming, immersive 4K gaming, color-accurate work, and daily productivity—this is one of the best options out there. The data backs it up with scores above 93 across gaming, office, and professional use. Just know that 'all' doesn't include portability; this is a heavy, feature-rich display meant for a serious setup. For the price, the performance and flexibility are hard to beat.
