KOORUI 24 Inch Computer Monitor FHD 1920 x 1080p 100HZ, Built-in Speakers, Ultra-Slim Bezels, 75mm VESA Mountable, Tilt Adjustable, HDMI, VGA, Black

I can only use this monitor at 144Hz since I'm using it via HDMI (no graphics card), but I used my laptop's DisplayPort USB-C connection to verify that it does have 240Hz capability for when I do get my graphics card in the future.The picture quality on this is insane. It's much better than my older Dell monitor with the exact same specs from a few years ago.The control system is also very intuitive. There are several options to enable variable refresh rate (also known as G-sync, I believe), toggle brightness and contrast, change color settings, and even add custom crosshair overlays on the monitor itself. This monitor is advertised as 1ms latency, and while I can't see this with my bare eyes, there is a function in the monitor's settings to increase its response time from "normal" to "fastest". This monitor supports HDR, scenario mode, and automatic scenario switching. While there is supposed to be a "volume" control, I haven't found a way to activate any internal speakers and don't believe there is a speaker in this monitor. Regardless, I have my own speaker.This monitor definitely isn't OLED (it's fast-IPS), but its HDR quality can compete with OLED since everything appears well-defined on it.The one thing I have to say bad about this monitor is it's hard to adjust. There is no way to turn it or increase its height. However, it's positioned at the optimal angle and setup for me, so I don't have to worry about that. I'd say this is a great monitor still! The specs are perfect for gaming, and the price is good for a general-use monitor.I don't immediately plan on playing games on this monitor, but probably will in the future so it's good to have the extra refresh rate and 1440p resolution.This feels very similar, if not better than, my brother's 144Hz LG monitor which cost more than this, so there's no real reason to choose another monitor. 27" is extra large (at least for me), but it's a good size if you don't plan on having anything else on your desk.

Buying this monitor for $200 on sale and getting 1440p with 240hz refresh rate is a great deal. Add in the HDR, great picture quality, and extremely easy-to-use settings interface, this monitor is extremely good. The thing that would make me give it 6 stars if possible is that I am also able to run it at 4k, although the max refresh rate is only 60. It has a 4k option but it was never even advertised as a 4k monitor. I could be mistaken and it's just a pointless option that doesn't actually work because it is hard to discern between 1440p and 4k, but, I have never come across a monitor that allows for a higher resolution in display settings if it cannot output it, leading me to believe it really does work. Regardless, the monitor came in great condition with excellent packaging. Absolutely recommend it to anyone wanting 1440p 240hz.

First off let me start by saying this is a great monitor. I was wanting a 3rd monitor for my setup. The monitor came secured and well packaged, no damages on the monitor or screen itself. The purchased 240hz monitor is the one on the bottom. I bought this to replace my 170hz 1440p monitor (one on top) to be able to play at 240hz. After mounting and connecting the monitors to my PC, I played around with the settings, you have to turn 240hz on in your display settings and mess around with the brightness and hdr on both the monitor and display settings to get it looking the best. I was able to play Fortnite at 240hz with amazing color quality using display port. The monitor above was $300 and this new monitor beats the image quality very nicely with the bonus of more hertz. I’ll definitely be keeping this monitor to play games at a great image quality and 240hz. If you’re hesitant about this monitor not being a known brand don’t be, give this monitor a try. It definitely exceeded my expectations.

The keyboard is very good and clean, the colors are really good and the 240hz is very good for gaming. However, sometimes it will just flicker for 5 seconds or so and then turn back on.
