KOORUI 27 Inch Gaming Monitor, 240Hz, QHD 1440P, IPS, 1ms, HDR 400, Adaptive Sync, Eye Care, HDMI/DP, VESA Compatible 27E3QK

This 27-inch 1440p 240Hz monitor offers good brightness and works well with both consoles and PC. Colour accuracy is decent, though other monitors can surpass it. It’s lightweight, easy to set up, and the refresh rate and overall quality meet my needs. Functionality is great, but the on-screen menu no longer lets me adjust brightness, and text/icons can be a bit sharp. For the price, especially on discount, it’s good value — ideal for a low budget, but if you have a mid-to-high budget, I’d recommend a higher-spec monitor.

Nice monitor, good colours, no problems whatsoever, I may even buy another to have dual monitor setup

Amazing value has very dark black and just a amazing vibrancy and colours, windows 11 is necessary for hdr, to properly calibrate it. If you want 10 bit colors you have to be in a 200hz mode. There is a slight amount of ghosting but nothing noticeable. The biggest problem is that the vrr is very bad very flickery but that can be fixed by limiting the range of the vrr using software just a rlly good monitor best value. It's very bright aswell

I bought three of these monitors in June 2024. I built myself a gaming simulation rig. I’ve been using this now for over 2 to 3 months and I’m absolutely over the moon the graphics on the monitor a smooth clear there’s not a glitch of error. I am absolutely so pleased with the value I’ve been through so many monitors to get this simulation right and nothing cut the mustard until I found these monitors the other bonus is they have three inputs so I also have my Mac attached to them so I can have my Mac on one screen and my windows on screens 2 &3. The only downside I have found is they’re not UHD.

I never write reviews and I was hesitant about this monitor at first, but this has blown me away (I own a far more expensive Corsair XENEON 27QHD240, which is an OLED monitor) and this still looks fairly good in comparison, if you want deep blacks and super bright colours you will still want to get an OLED but if you are using this as a second or third montor (which is my use case for this monitor as i use it for coding) this will serve you amazingly. Hands down the best budget monitor.

Super 240hz 1440p monitor, really took my computer to the next level. Gaming on this feels great. Lovely colours and very clear image

First off, this is the first monitor I've ever used that has caused me to feel ill the second it's turned on. The backlight has serious issues, which I assume is similar to a very very harsh PWM flicker. I'm not overexhaggerating how nauseous I feel when looking at it in addition to the severe eye strain and headaches. It's horrible. This monitor is cheap for a reason, and that's due to zero quality control on Koorui's part. I refuse to believe that I'm just sensitive to flicker either, as I've never experienced this with both budget and premium monitors and TVs in over 20 years of gaming. It's a very strange sensation. Your eyes are unable to focus on anything on the screen as they're being strained so much. The lower the refresh rate, including things like VRR affecting it, the stronger the sensation. It's disgusting. To make matters worse the backlight is extremely uneven. The left side of the screen is dark yellow, the right side bright and blue. You can't even calibrate it correctly as even the centre point has extreme deviations in a small square window. The other Koorui I tried, the £130 1080p 165hz variant, had a harshness when viewing the screen but not bad enough to cause this much discomfort, so that too is likely using some kind of PWM dimming for the monitor. It's cheap for a reason. Don't bother. Buy from a brand that is known to manufacture 100% flicker free monitors for the sake of your health. Ironically, despite it being a gaming monitor I've done no gaming the entire time I've owned it due to the nausea and headaches it causes.

Very good for price good picture quality and brightness also very smooth if you pc is good enough I definitely recommend
