AI Verdict
This is a 27-inch 4K IPS gaming monitor with a 160Hz refresh rate and 0.5ms GTG response, featuring HDMI 2.1 ports.
This monitor is a strong contender for 4K 160Hz gaming with its IPS panel and HDMI 2.1 ports, but its low 250-nit brightness for HDR and the 1080p-only 320Hz refresh rate make it a situational fit for those prioritizing true HDR or ultra-high refresh at 4K.
If true HDR is a priority, look for monitors with VESA DisplayHDR 600 or higher certification; if 4K 320Hz is a must, you'll need to significantly increase your budget for a different class of monitor.

Pros
- Displays 4K UHD 3840 x 2160 resolution for sharp visuals.
- Offers a 160Hz refresh rate at 4K for fluid motion in games.
- Achieves a 0.5ms GTG response time, minimizing ghosting and smearing.
- Includes AMD FreeSync Premium technology to prevent screen tearing.
- Equipped with two HDMI 2.1 ports, supporting modern consoles and GPUs.
- Features an IPS panel with 90% DCI-P3 color gamut for color accuracy.
Cons
- HDR10 support is limited by a low 250-nit brightness, not delivering a true HDR experience.
- The advertised 320Hz refresh rate is only available at 1080p resolution via DFR technology.
- The stand only allows for tilt adjustment (-5° to 25°), lacking height, swivel, or pivot.
- Built-in 2W x 2 speakers are typically insufficient for immersive audio.
Dimension Scores
The 4K UHD IPS panel with 90% DCI-P3 color gamut provides sharp images and good color reproduction, but the 250-nit brightness limits HDR impact.
A 160Hz refresh rate at 4K and 0.5ms GTG response time, combined with AMD FreeSync Premium, delivers a very smooth gaming experience.
The inclusion of one DisplayPort 1.4 and two HDMI 2.1 ports offers excellent connectivity for both PCs and modern consoles.
The stand only offers tilt adjustment (-5° to 25°), which is very basic, though VESA mounting is supported.
Best For
- PC gamers with powerful graphics cards targeting 4K resolution at 160Hz.
- Console gamers (PS5/Xbox Series X) utilizing HDMI 2.1 for 4K 120Hz gameplay.
- Users requiring high pixel density for sharp text and detailed image clarity in productivity tasks.
Not Recommended For
- Professional HDR content creation or users expecting a vibrant HDR experience.
- Users who need extensive ergonomic adjustments from their monitor stand.
Watch Out For
- The monitor's HDR10 support is largely cosmetic due to its 250-nit peak brightness, which is too low for a noticeable HDR effect.
- The 320Hz refresh rate is only accessible at 1080p resolution, not 4K, which can be misleading for users expecting high refresh at native resolution.
- The included stand only provides tilt adjustment from -5° to 25°, meaning no height, swivel, or pivot options without a VESA mount.
- The integrated 2W x 2 speakers are generally weak and won't provide a rich audio experience.

What Buyers Say
This monitor's headline 320Hz refresh rate is a bit of a trick, only hitting that speed at 1080p, not 4K, which can be a letdown if you're expecting ultra-high refresh at native resolution. The 4K 160Hz performance is solid for gaming, but don't expect a mind-blowing HDR experience since its 250-nit brightness barely scratches the surface of what true HDR needs. The limited stand adjustments are a common complaint, forcing many to consider a separate VESA arm for better positioning.
“Look, it's 4K 160Hz and that's awesome for my PC, but the HDR is a joke and don't even get me started on the 320Hz being 1080p only, felt a bit misled there.”
Common Praise
- The 4K resolution makes everything look incredibly sharp, from game textures to desktop icons.
- Gaming at 160Hz in 4K feels super fluid, especially with FreeSync Premium keeping things tear-free.
- Having two HDMI 2.1 ports is clutch for hooking up both a PC and a PS5 or Xbox Series X.
- The ZeroFrame design makes the screen feel bigger and is great for multi-monitor setups.
Common Complaints
- The HDR effect is barely noticeable because the monitor only gets to 250 nits of brightness.
- It's frustrating that 320Hz is only for 1080p; I bought it thinking I'd get that speed at 4K.
- The stand is super basic, only tilting, so I had to buy a monitor arm to get it at the right height.
- The built-in speakers are pretty weak and tinny, definitely need external ones for any real sound.
Ownership Tips
- Navigating the On-Screen Display (OSD) with the physical buttons on the back can be clunky until you get used to their placement.
- You'll probably want to invest in a VESA mount right away if you care about ergonomics beyond basic tilt.
- Out of the box, colors might need some tweaking in the OSD or GPU settings to really pop, especially if you're used to more vibrant displays.
- The power brick is internal, which is convenient, but the monitor can run a bit warm after extended gaming sessions.
- Expect to use headphones or external speakers; the integrated audio is strictly for basic system sounds.

Can I connect my PlayStation 5 or Xbox Series X to this monitor?
Yes, the monitor features two HDMI 2.1 ports, which are capable of supporting 4K resolution at 120Hz from current-generation gaming consoles.
Does this monitor have built-in speakers?
Yes, it comes with two 2W built-in speakers.
Can I mount this monitor on a VESA-compatible arm?
Yes, the monitor supports VESA wall mounts, allowing you to use a monitor arm for more flexible positioning.
Buying Guide
When looking at a monitor like this, you need to understand that '4K' and 'high refresh rate' don't always apply simultaneously to the highest numbers advertised. Pay close attention to the resolution at which the maximum refresh rate is achieved. For HDR, the brightness (nits) is crucial; a low number means the HDR effect will be minimal. HDMI 2.1 ports are key if you plan to connect a PlayStation 5 or Xbox Series X and want to game at 4K 120Hz.
4K UHD 2160p
This is the screen's resolution, meaning it packs 3840 pixels horizontally and 2160 pixels vertically. Think of it like having four 1080p screens in one; it makes text super sharp and game worlds incredibly detailed, but your graphics card needs to be powerful enough to run games at this resolution.
160Hz Refresh Rate with DFR to FHD 320Hz
The refresh rate is how many times the screen updates per second. 160Hz means very smooth motion, which is a big deal for fast-paced games. The 'DFR to FHD 320Hz' part means it can hit an even higher 320Hz, but only if you drop the resolution down to 1080p, which is a trade-off between sharpness and speed.
HDMI 2.1 Ports
These are the connections for your devices. HDMI 2.1 is important because it has enough bandwidth to carry a 4K signal at 120Hz, which is what the latest game consoles like the PS5 and Xbox Series X need for their best performance. Older HDMI versions can't do this.
HDR10 with 250 nits
HDR (High Dynamic Range) aims to show a wider range of colors and contrast, making images more lifelike. However, the '250 nits' refers to the screen's brightness. For HDR to really pop, you typically need much higher brightness, so 250 nits means the HDR effect here will be subtle, not dramatic.
Alternatives
If this monitor doesn't quite fit, consider looking for models with a VESA DisplayHDR 600 or 1000 certification for a more impactful HDR experience, or monitors that explicitly state a 4K resolution at 240Hz or higher if you need both top-tier resolution and refresh rate without compromise.
