AI Verdict
This 27-inch Fast IPS monitor delivers 4K 160Hz or FHD 320Hz with 1ms GTG, ideal for competitive PC and console gamers who want high refresh rates at both resolutions.
This monitor is a strong fit for gamers who want the flexibility of high-resolution 4K at 160Hz for immersive titles and the competitive edge of FHD at 320Hz for esports, all with a fast 1ms IPS panel. Its extensive connectivity, including HDMI 2.1 and USB-C, also makes it suitable for multi-platform setups.
If the dual-mode feature isn't a priority and you need better HDR, look for monitors with DisplayHDR 600 or higher certification and local dimming zones.

Dimension Scores
The 4K resolution, Fast IPS panel, 95% DCI-P3, and 130% sRGB coverage provide sharp visuals and accurate colors, though DisplayHDR 400 is a limiting factor for true HDR.
With dual modes of 4K 160Hz and FHD 320Hz, a 1ms GTG response time, ELMB Sync, and G-SYNC Compatible support, this monitor excels in motion performance.
It features HDMI 2.1, DisplayPort 1.4, and a versatile USB Type-C with DP Alt mode, offering broad connectivity for PCs and consoles.

Best For
- Competitive PC gamers who play both graphically intensive 4K titles and high-framerate esports.
- Console gamers (PS5/Xbox Series X/S) seeking 4K 120Hz with HDR and VRR support.
- Users needing a monitor for both gaming and productivity, benefiting from 4K resolution and 95% DCI-P3 color.
- Those with limited desk space who appreciate a compact stand with full ergonomic adjustments.
Not Recommended For
- Users prioritizing top-tier HDR performance, as DisplayHDR 400 is entry-level.
- Anyone needing robust USB-C power delivery (over 15W) or an integrated USB hub for peripherals.
- Budget-conscious buyers, as the dual-mode feature adds to the cost without universal perceived value.
Watch Out For
- The USB-C port only delivers 15W of power, which is not enough to sustain charge for power-hungry laptops like the M1 Pro MacBook.
- HDR mode often results in a 'washed out' or 'super dark' image, making it less desirable than simply leaving HDR off.
- Some units exhibit coil whine when running in the 320Hz FHD mode.
- ELMB Sync, while reducing motion blur, drops the monitor's brightness to a dim 30 nits, limiting its practical use.
- The OSD menu is described as low resolution with non-standardized setting names, making navigation less intuitive.

What Buyers Say
The most surprising aspect of user feedback is the mixed reception of the dual-mode feature; while some find the 320Hz FHD mode a 'game-changer' for competitive play, others question its real-world impact and value. The monitor is consistently praised for its sharp 4K image and smooth motion, but its DisplayHDR 400 implementation is a recurring disappointment, often described as making content look worse. Connectivity is a strong point, especially with HDMI 2.1 for consoles, but the low 15W USB-C power delivery and lack of a USB hub are notable omissions for productivity users. The stand's full adjustability is appreciated, though the black version's aesthetic is sometimes called 'plasticky'.
“Honestly, the 4K 160Hz is sick for my PC games, and my PS5 looks amazing, but that HDR is a joke, just leave it off, seriously. And why can't it charge my MacBook? Come on, ASUS!”
Common Praise
- 4K resolution provides incredibly sharp and crisp text and images, making productivity tasks like coding and editing a pleasure.
- The 1ms GTG response time and high refresh rates (4K 160Hz / FHD 320Hz) deliver exceptionally smooth and clear motion in games.
- Full compatibility with PS5 and Xbox Series X/S at 4K 120Hz with HDR and VRR is a significant advantage for console gamers.
- The stand offers extensive ergonomic adjustments including height, tilt, swivel, and pivot, providing comfortable viewing angles.
- The 95% DCI-P3 color gamut ensures accurate and vibrant colors, especially in sRGB mode for content creation.
Common Complaints
- HDR performance is poor, with users reporting 'washed out' whites or excessively dark scenes when HDR is enabled.
- The USB-C port's 15W power delivery is too low to effectively charge many modern laptops, limiting its utility as a single-cable solution.
- Some users experience audible coil whine, particularly when the monitor is operating in the 320Hz mode.
- ELMB Sync, while present, makes the screen too dim (30 nits) for practical use, reducing its effectiveness.
- The monitor lacks an integrated USB hub, meaning additional peripherals require separate connections to the PC.
Ownership Tips
- You'll likely need to adjust overdrive settings manually when switching between 4K 160Hz and FHD 320Hz modes to avoid ghosting or overshoot.
- The OSD menu, controlled by a joystick and rear buttons, takes some getting used to due to its low resolution and non-standard terminology.
- Despite the HDR certification, many users find the visual experience better with HDR disabled due to poor implementation.
- The black version of the stand might feel less premium than expected, while the white version receives more aesthetic praise.
- Expect to use a separate charger for your laptop if connecting via USB-C, as the 15W power delivery is minimal.
Frequently Asked Questions
Does this monitor have built-in speakers?

Is the USB-C port capable of charging my laptop?
The USB-C port supports DisplayPort Alt mode for video and provides 15W of power delivery. This is generally insufficient for charging most modern laptops, especially under load.
Is this monitor truly G-SYNC compatible?
Yes, the monitor is G-SYNC Compatible, FreeSync Premium, and VESA AdaptiveSync Display certified, ensuring variable refresh rate support with compatible GPUs.
What kind of HDR performance can I expect?
It is DisplayHDR 400 certified, which is an entry-level HDR standard. User feedback indicates that HDR can appear washed out or too dark, suggesting it's not a highlight feature.
Does the stand offer full ergonomic adjustments?
Yes, the included stand provides tilt, swivel, pivot, and height adjustments, allowing for a comfortable viewing experience. It is also VESA compatible.
Buying Guide
When looking at a monitor like this, you're paying for speed and resolution. The 'dual mode' means you can choose between a super-sharp 4K picture at a fast 160Hz, or drop the resolution to 1080p for an incredibly fluid 320Hz, which is a huge advantage in competitive games where every millisecond counts. Don't get too hung up on the HDR400 spec; it's a basic standard and often doesn't deliver a truly impactful HDR experience. Focus on the core panel performance and refresh rates for your primary use.
Dual Mode (4K 160Hz or FHD 320Hz)
This is like having two monitors in one. You get the stunning detail of 4K for immersive single-player games or work, and then with a quick switch, you can jump to a super-fast 1080p 320Hz mode for esports, where higher frames per second give you a competitive edge, similar to how a race car can switch between a high-speed track setup and a tighter, more agile configuration.
1ms Fast IPS
This refers to how quickly pixels can change color. 1ms (Gray-to-Gray) on a Fast IPS panel means you'll see minimal ghosting or blurring behind fast-moving objects, making action look crisp and clear, like watching a perfectly focused sports broadcast without any motion trails.
95% DCI-P3 Color Gamut
This indicates the range of colors the monitor can display. 95% DCI-P3 means it can produce a wider, more vibrant spectrum of colors than standard sRGB, making games and movies look richer and more lifelike, similar to how a high-quality art print uses a broader palette than a basic photograph.
Alternatives
If the dual-mode isn't essential, look for a dedicated 4K 144Hz+ IPS monitor with DisplayHDR 600 or higher for better HDR, or a 1440p 240Hz+ IPS monitor if you prioritize raw framerate over 4K resolution.
