LG Ultragear LG 27GX704A-B 27-inch Ultragear QHD (2650x1440) Review
The LG UltraGear 27GX704A-B offers elite OLED speed and contrast at a mid-range price, but its modest brightness means it's best for dimmer rooms.
The 30-Second Version
The LG UltraGear 27GX704A-B is a speed demon with perfect blacks, thanks to its 240Hz OLED panel. It's a fantastic value for competitive gaming and media, but its modest brightness holds it back in bright rooms. Worth it if your priority is motion clarity.
Overview
The LG UltraGear OLED 27GX704A-B is a 27-inch QHD monitor that's all about speed and contrast. It packs a 240Hz OLED panel with a near-instant 0.03ms response time, aiming to be the definitive screen for competitive gamers who want perfect blacks and no motion blur.
It's not just for gaming, though. With a color gamut hitting the 88th percentile and excellent ergonomics, it's a strong all-rounder for entertainment and even some creative work. But it's making some clear trade-offs to hit that competitive price point.
Performance
This thing is fast. Like, 'see every frame' fast. The 240Hz refresh and OLED's near-zero response time mean motion is buttery smooth with virtually no ghosting. Our data puts its overall performance in the 83rd percentile, which is solid. The trade-off? Peak brightness is a bit modest at 275 nits for SDR, though HDR can spike much higher. It's plenty bright for a dim room, but it might struggle against a sunny window.
Pros & Cons
Pros
- OLED contrast and pixel response are in a league of their own. 97th
- 240Hz refresh rate is incredibly smooth for competitive gaming. 85th
- Ergonomics are top-tier with full height, tilt, swivel, and pivot. 83th
- Color accuracy is excellent, hitting 98.5% DCI-P3. 82th
Cons
- Peak SDR brightness is only 275 nits, which is on the lower side. 29th
- Connectivity is basic, landing in the 35th percentile with just HDMI and DP.
- It's a heavy monitor, not exactly portable at over 15 pounds.
- The all-black design is functional but a bit plain for some setups.

Value & Pricing
For around $500, this monitor offers incredible value if your priorities are motion clarity and contrast. You're getting near-flagship OLED performance and elite ergonomics at a mid-range price. The catch is you're accepting lower brightness and simpler connectivity. Compared to more expensive OLEDs, it's a fantastic deal. Compared to bright IPS panels at this price, it's a different kind of beast.
vs Competition
Stacked up, it's a compelling alternative to pricier QD-OLEDs like the ASUS ROG Swift. You trade some peak brightness and maybe color volume for a lower price. Against a fast IPS monitor like many from MSI, you're choosing perfect blacks and instant response over higher sustained brightness. And next to the giant, super-wide Samsung Odyssey Neo G9, this is for the player who values pixel-perfect speed over immersive scale. It carves out a smart niche.

Common Questions
Q: Is this monitor bright enough for a well-lit room?
It hits 275 nits for standard content, which is decent but not exceptional. It's best suited for a room with controlled lighting, not direct sunlight.
Q: How does the 0.03ms response time actually feel?
It feels instant. In our testing, motion blur is virtually eliminated, which is a huge advantage in fast-paced games over typical 1ms IPS panels.
Q: Does it work with both AMD and NVIDIA graphics cards?
Yes, it's AMD FreeSync Premium Pro certified and also officially G-Sync Compatible, so it'll work smoothly with GPUs from either brand.
Who Should Skip This
Skip this if you work in a super bright office or edit HDR video professionally. The sustained brightness isn't high enough. Also, if you need a ton of USB ports or a built-in KVM switch, look elsewhere because the connectivity here is pretty basic.
Verdict
Buy this if you're a competitive or enthusiast gamer who plays in a controlled lighting environment and values flawless motion over eye-searing brightness. It's also a great pick for media consumption and anyone who craves those inky OLED blacks. Just know you're getting a focused tool, not a do-everything marvel.
