I’ll be honest - I wasn’t expecting much from KOORUI, but this 27” has genuinely impressed me over the past few months of daily use. The 1440p IPS panel punches well above its price point. I’m using it on a 3rd party swing arm system. The built in stand is a bit short. Colors are vibrant with that 95% DCI-P3 coverage actually showing up in real-world usage, not just on paper. Text is crisp for coding work, and the 100Hz refresh rate makes a noticeable difference in games - especially coming from standard 60Hz panels. What really stands out is the lack of compromises you’d expect at this price. No backlight bleed on my unit, FreeSync/G-Sync compatibility works seamlessly, and the 1ms response time actually delivers during competitive gaming sessions. The HDR10 isn’t reference-level, but it’s functional and adds some pop to content. Build quality feels solid despite the ultra-thin profile. Packaging is solid and stylish - which matters to me for discount brands. The custom DC power connector is mildly annoying, but that’s honestly my only real complaint. For the money, this competes directly with monitors costing 30-40% more. KOORUI seems to have found the sweet spot between features and price that bigger brands struggle with.

Not quite as bright colors as my LG monitor, but for a high resolution monitor used for work (not gaming) it is great value.

As a note to new buyers: a chemical-like odor may be emitted from your monitor's exhaust for the first 2-3 weeks--at least mine did. I did some research and this was likely attributed to some cleaning chemicals from the factory, and it is burning off from the heat of the monitor. Simply have good ventilation in your room, and the odor should dissipate in 2-3 weeks. I've had this monitor for over a year now, and there is no odor anymore. Now, for the actual review: This monitor is great quality for the price! Not perfect, as I've found this monitor doesn't display smooth gradients of dark very well. For example, when I'm in a dark room in a video game, the dark ambient colors show slightly pixelated rather than smoothly blended. Other than that, this monitor works like a charm! Colors are great, and monitor settings are easily adjustable. One complaint I have is that I can't change the monitor's brightness using the Windows OS' brightness settings--you have to change the brightness/contrast using the monitor's buttons.

was hesitant due to not knowing anything about the brand, but all the specs suited our needs. Set up at our office, and I was pleasantly surprised how nice it is. Great image quality, simple design, easy to navigate options. Power button is in an odd spot that I am not adjusted to yet, but a barely turn off my monitor at the office and it goes into sleep mode/power save. Not a lot of ports, but I knew that reading the description, so I was aware.

This is a very good monitor and will do any office work just fine. I was concerned about the ips vs oled situation however it wasn't a problem at all. I also want to bring attention to the stand. Unlike other monitor stands, this one is very straight and isn't intrusive which is great for desktop space. Some things I didn't like were the color accuracy and refresh rate. The color accuracy was fine most of the time but in some games dark browns get a really red tint. There might be some color setting to fix this however I didn't bother to find it. The other issue was the refresh rate being only 100hz. Like i said it is good for office work however for gaming, especially competitive, it feels slow and can be limiting.

Great Budget gaming monitor and easy to setup, although i will say make sure to get the rught monitor arm stand if you want to get that.

This is the 3rd Koorui 27" monitor I've ordered in the past 4 years. All have worked great without any issues. Highly recommended. I'm not a heavy gamer though, so that might make a difference but every performance option I've set has worked appropriately. Only issue is the change model #'s and features available on them change all the time and some of the settings can be confusing, and instructions are lacking as to what each setting actually does. Not the only manufacturer that's guilty of this though. Has a good variety of inputs on this particular one. I do have to force it to run 1920x1080P instead of the default 2K to avoid mouse jumping between my other monitors. Win 11 immediately recognized it as HDR (turned that off for my use). No odd coloring or dead pixels on any that I've purchased and others working fine well out of the warranty period.

The KOORUI 27 QHD monitor delivers good image quality. The 1440p resolution combined with a 144Hz refresh rate and 1ms response time makes gaming feel fluid and responsive. Colors are vibrant thanks to the 90% DCI-P3. The support for both FreeSync and G-Sync its not really great, the HDR cant be adjusted ,the VA panel does show some noticeable ghosting in dark scenes, especially in fast-paced games. The stand is also quite basic—no height adjustment or swivel—which limits ergonomics ,Still, it’s a solid choice for gamers who want high resolution and smooth performance.
