Koorui GP01 Review: 24″ 1440p 165Hz FreeSync IPS Gaming Monitor

The Koorui GP01 is a 24" 1440p 165Hz FreeSync gaming monitor based on an IPS panel with a fast response time and 100% sRGB color gamut.

Bottom Line

The Koorui GP01 is the only 24″ 1440p 165Hz IPS gaming monitor available in the US. Luckily, it’s attractively priced and offers excellent performance, image quality and features!


Many gamers have been patiently waiting for a 24″ 1440p high refresh rate IPS gaming monitor – and one has finally come to the US! Meet the Koorui GP01.

Image Quality

Ever since AOC and Philips announced their 24″ 1440p 165Hz IPS gaming monitors, the AOC Q24G2A and the Philips 24M1N5500Z, we’ve been receiving many messages from our readers asking us when (and if) these are coming to the US.

Sadly, while AOC eventually made their model available in Europe, it doesn’t look like they’ll be releasing it in the US. Luckily, there’s the Koorui GP01, which is based on the same BOE MV238QHM-NF0 panel; it’s basically a rebranded HKC MG24P1QS.

So, what makes this monitor so special?

Most competitive FPS players prefer 24″ sized screens as they’re neither too big nor too small. This allows them to keep track of everything that’s happening on the screen without having to move their eyes or neck as much as they would on larger displays.

However, many gamers don’t like the usual Full HD resolution – and Quad HD is a lot sharper on 24″ sized screens. Plus, modern mid-range CPU/GPU builds can easily maintain high frame rates at 1440p in popular eSports titles.

The 2560×1440 QHD resolution on a 23.8 viewable screen of the Koorui GP01 monitor provides you with a pixel density of 123.41 PPI (pixels per inch). As a result, you get plenty of screen real estate with sharp details and text. The overall crispness is between that of 27″ 1440p (108.79 PPI) and 31.5″ 4K (139.87 PPI) displays.

Next, the Koorui GP01 uses an IPS panel with a 100% sRGB color gamut, which results in accurate colors for sRGB SDR content and no over-saturation, though some users prefer wider color gamuts for extra vibrancy and more saturated colors.

The image is consistent regardless of the angle you’re looking at the screen thanks to the 178° wide viewing angles.

Further, the Koorui GP01 has a strong 350-nit peak brightness, meaning that it can get more than bright enough to mitigate glare even in well-lit rooms.

As expected from an IPS panel, the static contrast ratio is around 1,000:1, so you won’t get as deep blacks as that of VA panels with a usual contrast ratio of ~3,000:1 – however, VA monitors in this price range have significantly slower response times.

The monitor also supports HDR (High Dynamic Range). Since it doesn’t have local dimming nor a wide color gamut, you won’t be getting a proper HDR viewing experience, though some content will benefit from a boost in peak brightness to 400-nits and 10-bit color depth for smoother gradients.


The Koorui GP01 has a maximum refresh rate of 165Hz, which provides you with a big boost in motion clarity in comparison to the standard 60-75Hz displays.

Input lag is also reduced to ~4ms, which makes for imperceptible delay between your actions and the result on the screen.

Next, the monitor has a rapid 1ms GtG pixel response time speed and there’s no noticeable ghosting or overshoot behind fast-moving objects (regardless of the refresh rate) when using the default Normal overdrive mode.

Variable refresh rate (VRR) is supported as well via AMD FreeSync and NVIDIA G-SYNC Compatible technologies.

Although the Koorui GP01 doesn’t have the official G-SYNC Compatible certification by NVIDIA, VRR works with compatible GeForce (10-series or newer) graphics cards without issues over DisplayPort, whereas FreeSync works over both DP and HDMI.

The backlight of the monitor is completely flicker-free and there’s a hardware low-blue light solution that filters out the harmful low-blue lights.

At the rear of the monitor, you’ll find a direction joystick for quick and easy navigation through the OSD (On-Screen Display) menu.

Besides the standard image adjustment tools (brightness, contrast, color temperature, etc.), you’ll also find some gaming features, such as crosshair overlays and on-screen timers.

Design & Connectivity

Koorui GP01 Design

The stand of the monitor is sturdy and offers full ergonomic support, including up to 110mm height adjustment, -5°/15° tilt, +/- 30° swivel, 90° pivot and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.2, two HDMI 2.0 ports (limited to 144Hz at 2560×1440) and a headphone jack.

Price & Similar Monitors

The Koorui GP01 goes for ~$200, which is excellent value for money. If you don’t mind a bit larger screens though, you can find 27″ 1440p 165Hz IPS models with a wide color gamut for a similar price, such as the Acer XV271U M3.
