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.

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

This is a great monitor but does need some tweaking out of the box. On the monitor's menu, turn Adaptive-Sync on. Change RGB to 47 red, 49 green, 50 blue. Response Time to Fast. I increased brightness to 95 but this is personal preference. Disable HDR. On your computer in System -> Display -> Advanced display, change refresh rate to 240hz. I personally changed scale to 125% to make text more readable. I've also forced G-Sync on using NVIDIA Control Panel as my GPU isn't always powerful enough to hit 240fps, which can result in input lag. Overall it's a pretty good monitor, especially for the price. Just bear in mind that you may experience ghosting if your GPU isn't up to par. In that case, you should turn G-Sync on and use the Fast response time on the monitor. I'd avoid HDR as it's only 400 which isn't worth using in my opinion.

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.

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.

Ottimo prodotto qualità- prezzo. Immagini nitide e di ottima qualità ma presenta una piccola pecca. Anche impostando dal pc l'uscita audio su HDMI al massimo non si sente nulla. Un vero peccato perchè sarebbe stato un prodotto veramente completo.

Vu le prix, c’est un super écran ! Ça fait plus d’un an que je l’ai et j’en suis toujours très satisfaite. J’ai pu tester d’autres produits de chez KOORIU et c’est vraiment une marque avec un excellent rapport qualité-prix. Je recommande !

Senza infamia e senza lode. Buono il prezzo, discreta l’immagine, un po’ scadente il materiale

Toller & billiger Monitor, vorallem empfehlenswert als Erweiterung zu einem Hauptbildschirm. 1080p auf 24 Zoll ist ausreichend scharf genug, die Farben werden mit etwas feineren Einstellungen per Grafiktreiber super dargestellt. Der Bildschirm an sich sieht schick aus, da vorallem die Ränder sehr schmal sind! PS: Lässt sich auch sehr leicht an eine Wandhalterung mit Vesa 75x75 montieren, da der Rücken des Bildschirmes an der Halterung flach ist. Da die Löcher allerdings relativ kurz sind, sollte man kürzere M4 Schrauben parrat haben für eine feste Montierung.
