LG UltraGear LG UltraGear 27" Dual Mode 4K UHD 180 Hz / FHD 360 Review
The LG UltraGear 27G810A-B tries to be two monitors in one: a 4K detail machine and a 360Hz speed demon. We tested it to see if this dual-mode trick is genius or just confusing.
The 30-Second Version
A 4K/180Hz and 1080p/360Hz monitor in one. It's the Swiss Army knife for gamers who can't decide between resolution and speed. Hunt for a sale price.
Overview
The LG UltraGear 27G810A-B is a monitor that tries to be two things at once, and it mostly succeeds. The one thing you need to know is that it's a 4K 180Hz screen that can also switch to a 1080p 360Hz screen. That's the 'Dual Mode' trick. It's a clever solution for gamers who want high-resolution detail for single-player games and blistering speed for competitive shooters, all without buying two monitors. Our data shows it scores in the 95th percentile for both color and performance, so this isn't just a gimmick—it's a genuinely high-performing panel.
Performance
What surprised us was just how good that IPS panel is. With a 95th percentile color ranking and 400 nits of brightness, games and movies look fantastic. The 1ms response time and G-Sync/FreeSync Premium support mean the 180Hz refresh rate feels buttery smooth at 4K. Switching to the 360Hz FHD mode is seamless, and the jump in motion clarity is immediately noticeable. For a 27-inch screen, it packs a serious punch that lives up to its 'UltraGear' branding.
Pros & Cons

Cons

- No built-in speakers, which is a minor miss at this price.
- The HDR10 support is fine, but don't expect mini-LED levels of contrast.

Value & Pricing
Prices are all over the place, from $347 to $595. At the lower end of that range, this monitor is an absolute steal. At nearly $600, you're starting to eye OLED competitors. Our verdict? Hunt for a deal under $400. That's where the value proposition becomes undeniable for a display this versatile and performant.
vs Competition
This monitor sits in a weird, cool niche. The Samsung Odyssey Neo G9 or LG's own 45-inch UltraGear offer more immersive curves and screen real estate, but they're massive and expensive. The ASUS ROG Swift 32" QD-OLED has better contrast and response times, but it's also more expensive and you lose the dual-resolution trick. For a straight-up 27-inch 4K high-refresh rate comparison, the Dell UltraSharp 27" is more office-focused with a lower 120Hz refresh. The LG's unique party trick is letting you choose between pixel density and raw speed.

Common Questions
Q: Is this good for both work and gaming?
Absolutely. The 4K resolution is sharp for text and productivity, and the high refresh rates and adaptive sync make it a gaming beast. It scored a 79.8 for professional use in our tests.
Q: Do I need a special cable for the high refresh rates?
Yes. To get 4K at 180Hz, you'll need to use the DisplayPort 1.4 cable it comes with or a high-speed HDMI 2.1 cable. Don't use an old HDMI cable.
Q: Can I wall-mount it?
Yep, it has a standard 100x100mm VESA mount pattern on the back, so you can pop it right onto an arm or wall bracket.
Who Should Skip This
If you're a console-only gamer or your PC can't handle 4K gaming above 60 fps, you're paying for features you won't use. Also, if you crave the infinite contrast of OLED for dark room gaming, look at the ASUS QD-OLED instead. This LG is for the high-end PC enthusiast who wants options.
Verdict
If you're a PC gamer with a powerful GPU who plays both cinematic story games and fast-paced competitive titles, this monitor is a fantastic one-stop-shop. The Dual Mode feature is genuinely innovative and practical. Just make sure your graphics card can push 4K at high frame rates, and try to snag it when the price dips below $400. It's a strong, versatile recommendation for its target audience.
