Style: 27" Fast IPS 4K 160Hz / 320HZ FHD G-SYNC
I’ve been using this monitor for a few days now (received in January 2026), and so far my experience has been excellent. My graphics card is an ASUS TUF Gaming NVIDIA GeForce RTX 4080 Super OC Edition, and at first, I had some doubts about reaching the full 160Hz at 4K in Windows. I followed many comments and reviews online and tried different cables. I even bought a certified HDMI 2.1 (48Gbps) cable, thinking that would solve the issue. While that cable works perfectly, with HDMI I could only reach 4K @ 120Hz uncompressed, which seems to be a limitation of how this monitor and NVIDIA GPUs handle HDMI. However, the DisplayPort cable included in the box works perfectly. Using DisplayPort, I can get 4K @ 160Hz in Windows without any issues on my RTX 4080 Super. On macOS, I was also able to reach 160Hz using HDMI, which worked smoothly. The dual mode is another big advantage: I tested 1080p at 320Hz, and it works very well for competitive gaming. Motion is extremely smooth and responsive. Regarding performance, DisplayPort uses Display Stream Compression (DSC) to achieve 160Hz at 4K. This adds only about 0.1–0.3 ms of latency, which is completely negligible in real gaming. In practice, the higher refresh rate reduces overall input lag compared to 120Hz, so gaming actually feels more responsive. Image quality is excellent, colors look vibrant, and build quality feels solid. I haven’t noticed any input lag issues, stuttering, or visual artifacts. I’ve only had the monitor for a short time, so I may update this review in the future if anything changes. For now, based on my experience, I’m very satisfied and giving it 5 stars. I will also upload a video as evidence showing the refresh rates working correctly. Highly recommended if you’re looking for a versatile and high-performance 4K gaming monitor.

Absolutely hands down the BEST monitor I've ever purchased. A true gaming monitor with a multitude of adjustments (height, swivel, screen rotation, etc). Picture quality is absolutely incredible 4K (seems higher) with zero issues of ghosting, fading, or color loss. Deep dark blacks and brilliant colors. The stand is heavy duty and of quality construction. Added bonus of RGB color changing lights on the logo at the back of the monitor. Would buy again! AAA+++

Really impressed with this monitor. The 4K resolution is super sharp and makes everything look clean and detailed, whether I’m gaming, watching videos, or just doing everyday work. Colors look vibrant and accurate, and HDR adds a nice boost in contrast without feeling overdone. The size at 27” feels like a sweet spot for 4K, giving plenty of screen space without being overwhelming. It’s also very smooth in performance, and everything feels responsive, especially for gaming. The build quality is solid and the design looks clean on the desk. Overall, it’s a great all-around monitor that works well for both gaming and productivity.

Loving this monitor so far. These monitors eliminated the use of a docking station because i wanted to share two external screens. These monitors allowed me to do that and use my laptop monitor while sending back my docking station. Input switching was unknown to me and its a great technology. Great price on some great monitors.

Bought two when they dropped it price. Thankfully I did because now they're double the price in less than a month! Haven't had proper monitors since buying one top of the line in high school 2008. What a difference. 144hz is phenoms. The personal settings per monitor are a plus. One of a kind monitor stand that allows for full directional positioning and it's a firm stay. Mounting does require a lot of space behind a desk or to the wall. These are hefty monitors.

I've been looking to get a new monitor for some time now. I wanted one that would meet all of my criteria. 4k 24"-32" around $250 (this obviously wasn't met) IPS panel 120+hz Vesa mount compatible This monitor checked all the boxes except the price, but I was willing to spend a little more if it meant I was getting a great monitor. And it is -- mostly. The picture is nice, vivid and smooth. It handles high frames without a problem. The 27" size is perfect on a monitor arm to get it positioned exactly where you want it. Games are beautiful in 4k and there's not much issue, most of the time. The included display port cable is a nice addition and supports DP1.4. The thin bezels are a little misleading, there's still a border under the glass that makes the bezel larger than you'd think it was. The first product picture shows it well, the black you see around the top, left and right, most of that is under the glass and not the plastic surround of the monitor, if that makes sense. The menu is strange and the monitor has buttons to shortcut to certain settings, but it's all still in the menu. The extra buttons seem unnecessary to me. Parts of the menu are easy to get to and other options are hard to figure out why they are greyed out. I haven't tried the 'app' yet, as I'm not sure if that requires a usb connection or not (usb cable NOT included). Vesa mounting is trickier than it needs to be, you have to pry off the plastic pieces around the monitor arm to get to the screws to take off the arm (the instructions aren't very helpful with this). Basically if you look at the plastic circle you can see that it's two different sections. Where they meet around the bottom at about the 4-5 o'clock position there's a 'ramp' edge. If you take a flat head screwdriver you can wedge it in there and pry it up. But instead of doing that, since you probably will mar up the plastic, just try giving it a firm tug and rock it back and forth first. It's just clipped in and comes off with a little bit of force. The space to mount an arm is limited. It has to be square, if your arm's plate has extended rounded edges or anything that makes it larger than a a regular square shape, it probably won't fit, unless you want to get creative with spacers and longer screws, but I don't recommend that. Here are my main issues with this monitor: Changing anything in the settings is SLOW. The monitor will turn off and take it's sweet time coming back or might turn on/off several times. Detecting an input is SLOW and will turn on and off multiple times before it stays on. I have two monitors connected (other is an LG) both on DP and the Asus takes about 10+ seconds longer to 'turn on' compared to the LG. I'm not sure if it's the same on HDMI, but I'm not willing to give up the performance I paid for to have it on HDMI instead of DP. I also get a strange bug randomly. My second monitor will start getting like tv scan lines from the top of the monitor and go down about an inch of the screen at which time the asus monitor shuts off then turns back on. It will keep doing this until I unplug both monitors from the graphics card and plug them back in. Sometimes it requires a reboot to fix. I NEVER had this issue before using this monitor, so I can safely say that it's causing the problem and it's not an issue with my graphics card. I just can't figure out why it's happening. It might be that my other monitor is 1080p and a smaller size and strange things are happening at random times, really not sure. The issue hasn't happened in a few weeks at the time of me writing this, but it sure is annoying when it happens. The biggest one though is their form of local dimming (at least I assume that's what it is). The backlight turns on in columns based on what is on the screen and where. On dark scenes or areas in a game you will see it. If you move your mouse across a dark screen you will see the columns of light travel across the screen. I had an fps counter in the top left, and when I played anything that had a dark scene, the whole left side of the screen would be lit up with a column of light. Watching movies on this would be a disaster, if it has black borders. It might just be the HDR, I'm not fully sure since I haven't tried turning it off yet (again something I paid for, I shouldn't have to turn it off to make things look better, when it's a feature that IS supposed to make things look better). Including a video to demonstrate this. Overall though, the cons aren't a big enough issue for me to return it, but I think I will be keeping an eye out for an OLED monitor to replace it and my older LG.

This is a upgrade from 1080p, and it's definitely worth it. I always have brightness turn off at night and with old monitor, the image is always trouble, but this monitor solve it. With only high contrast and zero brightness. Image is still bright enough to play games and browsing. However, setting is complicated in my opinion. Had to try out various ways to make sure, it's not too bright and has great contrast, especially with f.lux.
