I bought this monitor to use with my MacBook Pro M3, and it works perfectly at 4K resolution with a 120Hz refresh rate. One thing I especially like due to my not perfect eyesight is using 200% scaling in macOS—it provides larger, crisp UI elements while still taking full advantage of the sharp 4K display, making it very comfortable for everyday work. The picture quality is excellent, with vibrant colors and sharp text. Setup was quick, and the monitor has a clean, modern design. My only minor complaint is that the dedicated button for switching to 240Hz is located very close to the main joystick/menu button, so it’s easy to press it by mistake when navigating the on-screen menu. Overall, it’s an excellent monitor that offers great image quality and outstanding value for the price.

This is such a great monitor! It's so good, I now have two of them. One horizontal and one vertical. Being a QD MiniLED means i never have to worry about burn-in when gaming and especially doing engineering work. Being 4K, along with 1,400 nits of peak brightness, 300,000:1 contrast ratio and 1.07 billion colors means the text and imagery in general is bright and crystal clear. I might eventually buy a 3rd monitor but right now, I couldn't be happier with the quality of these monitors!!!

I run three screens for photography editing and app development. I'm not a gamer, so I won't pretend to have opinions on refresh rates or response times, that's not what I bought this for. What I did buy it for, it delivers. The IPS panel produces accurate, consistent color, important when you're making actual decisions based on what you see on screen. Resolution at 1440p is well-suited for detailed work without demanding a NASA-grade GPU to drive it. And at this price point, it frankly punches above its weight class. The bezel is impressively slim, which matters when monitors are sitting shoulder to shoulder. However, the active display area doesn't extend fully to the inner edge of the bezel. There's a small but visible gap between where the bezel ends and where the image begins. In a single-monitor setup you'd likely never notice. In a multi-monitor array, your eye catches it at the seams. Not a dealbreaker, but worth knowing before you buy. Four stars without hesitation. For creative and productivity use, it's a lot of monitor for the money.

Review: I purchased two of the Koorui 34‑inch curved ultrawide monitors for a dual‑monitor setup, and so far I’m very pleased with them. The picture quality is sharp, the brightness is solid, and the “Normal” color preset looks natural without any adjustments. For the price, these 34‑inch panels deliver very good performance. That said, there are a few important details the product listing and reviews don’t mention — and knowing them ahead of time would have saved me some stress during installation. 1. YES, the 34‑inch model DOES include stand‑offs (spacers) This is not mentioned anywhere in the listing, and even Amazon’s Rufus incorrectly says they are *not* included. They actually come in the small accessory packet with the manual. If you’re mounting these monitors, you will need those stand‑offs because of the recessed VESA pattern. They are already in the box — just not advertised. I rushed to order a separate spacer kit because the listing didn’t mention it, so I’m putting this here to help the next person avoid that. 2. One of my monitors flashed briefly until I disabled FreeSync On one of the two monitors, I noticed a quick bright “flash” when moving the mouse. Turning off Adaptive Sync / FreeSync in the monitor’s menu fixed it instantly. The other monitor didn’t have this issue, so it seems to vary by panel. Not a defect — just something to be aware of if you see flicker or brightness pops. 3. Color and brightness match well once set manually After setting both monitors to the same brightness, contrast, and color mode, they match very well side‑by‑side. The “Normal” color preset looks the most accurate on these VA panels. 4. Build quality and packaging are solid Both monitors arrived well‑protected, and the included cables work fine. The stand is basic, but I’m using monitor arms, so that wasn’t a factor for me. 5. Too early to comment on long‑term support or durability I’ve only had these monitors set up for a few hours, so I can’t speak yet to long‑term reliability or how responsive Koorui’s support is. I’ll update this review if anything changes over time. Bottom line: These 34‑inch Koorui ultrawides are excellent for the price, especially for gaming or a dual‑monitor setup. Just be aware that: - Stand‑offs ARE included (despite the listing not saying so) - FreeSync may need to be turned off on some units - Picture quality is great once you match settings manually - Long‑term support is still unknown If the listing had mentioned the included spacers, it would have saved me a last‑minute order — so I hope this review helps the next person.

I’ve been using this monitor for a bit and I’m really happy with my purchase. Going from 60hz to 180hz and 1080p to 1440p was an absolute game changer for me. Colors were also very vibrant and look great right out the box. I’ve had no problems with this monitor and it’s still going strong. Highly recommend if you want a high-refresh rate gaming monitor.

If you were looking for a decent gaming monitor with a good refresh rate, you better keep looking. Honestly, I wanted to really like this thing. For $120, it ticked off a lot of great features for me: at least 120Hz refresh rate, 1080p quality, and some nifty reticule marks for FPS gamers like myself. And for a year I had no problems with it until a few days ago. The ability to control input's, power, and toggle the reticule features all lie on one singular button behind the monitor. Here lie's the issue; if that power button starts messing up, there is no way to control or turn on/off the monitor. This is exactly what happened on my unit; the power button/control went out and the monitor was basically useless. I contacted Koorui support via email, and all I got was a vague "Did you confirm the button is really broken" response. Replied back that I did, and the manufacturer has ghosted me. Basically, I HIGHLY advise you just save up a few $80 or $100 dollars and get a decent entry level gaming monitor. By going cheap with this one, you will just end up probably wearing out the power/control button and be left with an expensive paperweight. If you are DIY repair savvy, I am sure that replacing the power/control button probably is not that big of a deal. In which case, go right ahead as it is a decent monitor for the price. But with that said, having this thing break leaves you with basically no options to get it fixed and good luck trying to get a hold of Koorui for support. Sadly, this is a growing trend on buying electronic's here on amazon from smaller brand sellers. *Update* So as of writing this review, I got Koorui to reach out to me. They would agree to replace the monitor for free, but I would have to front the shipping costs. They have their operations out in California, so if you live on the east coast then expect to pay around $40-50 for shipping for the monitor all the way out there (nearly half the monitor's value). I told Koorui that this just did not make any financial sense and they offered to refund me 50% of the monitor's value. However, they have yet to specify how they will send the refund, so I am unsure of whether I will see my partial refund when this is all said and done. So know that if you do proceed to get this monitor and need to return it past the 30 day return window covered by Amazon. TLDR: just save up an extra $50-100 for a big brand gaming monitor and save yourself the headache of dealing with all of this.
