Dimension Scores
The Fast IPS panel delivers 133% sRGB and 97% DCI-P3 color coverage with factory calibration, but HDR400 performance is weak.
The 180Hz refresh rate and 1ms GTG response time, combined with variable overdrive, provide extremely fluid motion.
Includes DisplayPort 1.4, HDMI 2.0, and USB-C with DP Alt Mode, but the USB-C power delivery is limited to 7.5W and there's no additional USB hub.
The stand offers tilt, swivel, pivot, and height adjustments, plus VESA compatibility, for extensive positioning flexibility.
Best For
- PC gamers playing fast-paced titles at 1440p resolution

- Content creators or casual photo editors who need accurate sRGB color reproduction
- Anyone looking for a monitor with extensive ergonomic adjustments
Not Recommended For
- Users expecting a true HDR experience for movies or games
- Laptop users who need significant power delivery (e.g., 65W+) via USB-C

What Buyers Say
Users are consistently impressed by the smooth motion and color accuracy of this monitor, especially for its price point. The 180Hz refresh rate and 1ms response time are frequently highlighted as delivering a competitive edge in games. However, the HDR performance is a recurring disappointment, with many noting it doesn't add much to the visual experience. The limited 7.5W power delivery over USB-C is also a common point of frustration for those hoping for single-cable laptop charging. The physical OSD buttons on the back are sometimes mentioned as less convenient than a front-facing joystick.
“Okay, so the 180Hz and 1ms are legit, games look SO smooth, and the colors are actually really good for an IPS, but seriously, the HDR is a joke, don't even bother turning it on, and that USB-C power? My phone charges faster.”
Common Praise
- Motion clarity is significantly better than other IPS monitors, even rivaling 240Hz displays
- Factory calibration in sRGB mode is accurate, allowing for tweaking settings while maintaining gamut emulation
- Variable Overdrive works exceptionally well, eliminating overshoot across all refresh rates
- The stand is sturdy and provides a wide range of ergonomic adjustments, including height, tilt, swivel, and pivot
- USB-C connectivity for video input is convenient for connecting laptops or other devices
- Colors look rich and vibrant with 97% DCI-P3 coverage
Common Complaints
- HDR400 is not impactful; blacks look gray and it lacks local dimming
- USB-C power delivery is too low (7.5W) to charge most modern laptops
- No additional USB ports for connecting peripherals directly to the monitor
- ELMB Sync can show artifacts and doesn't perform well at lower refresh rates
- HDMI 2.0 ports are a limitation for current-gen console features
- Some users experience eye strain or difficulty with small text at 1440p on 27 inches without scaling
Ownership Tips
- The variable overdrive feature means you don't have to constantly tweak settings for different games or refresh rates.
- The phone holder on the stand is a nice touch, but larger phones or those with thick cases might not fit.
- DisplayWidget Center software makes adjusting settings much easier than using the physical buttons on the back.
- Even with the matte coating, some users find the brightness sufficient to combat glare in well-lit rooms.
- The lack of a true USB hub means you'll still need a separate hub or dock for multiple peripherals if using USB-C for video.

Buying Guide
When you're looking at a gaming monitor like this, you need to think about how fast it can draw new images (refresh rate) and how quickly pixels change color (response time). A higher refresh rate, like 180Hz here, means smoother motion, which is crucial for competitive games where every millisecond counts. A low response time, like 1ms, reduces blur behind moving objects. Also, consider the panel type; IPS panels usually give you better colors and wider viewing angles than VA or TN, but might not have the deepest blacks.
180Hz Refresh Rate
This is how many times per second the screen updates its image. Think of it like frames per second in a movie; 180Hz means 180 frames per second, making motion appear incredibly fluid and responsive, giving you an edge in fast-paced games.
1ms GTG Response Time
This measures how quickly a pixel can change from one gray shade to another. A 1ms response time minimizes 'ghosting' or 'smearing' behind moving objects, keeping the image sharp and clear during intense action, like a race car leaving a crisp trail instead of a blurry one.
Fast IPS Panel
IPS (In-Plane Switching) panels are known for their accurate colors and wide viewing angles, meaning the picture looks consistent even if you're not sitting directly in front of it. 'Fast IPS' means it achieves these color benefits without sacrificing the low response times needed for gaming.
QHD (2560x1440) Resolution
This is the number of pixels on the screen. 1440p offers a significant step up in sharpness and detail from standard 1080p, without being as demanding on your graphics card as 4K, providing a great balance between visual fidelity and performance for a 27-inch screen.
Alternatives
If this monitor doesn't quite fit, look for a monitor with a higher VESA DisplayHDR certification (600 or 1000) for better HDR, or one with 65W+ USB-C power delivery and a built-in USB hub if you need to charge a laptop and connect multiple peripherals.
