The Koorui GP01 answers the demand for a smaller 1440p screen without breaking the bank. Smaller than 27-inch QHD monitors are not common, but the niche product has some demand from meticulous gamers. Let’s take a closer look to see if the GP01 can outmatch some premium options in the market.

Design and Features
The Koorui GP01 has a simpler aesthetic that doesn’t look too gaudy like some budget monitors from competing brands like Viotek. The monitor has a matte black finish, but its red accents break its office-centric vibe. The display has a bezel-free design, but it still has inner borders like most models.
What makes this model additionally appealing is its size, which barely breaches what most office monitors come with. It doesn’t take too much depth or width, but its screen will show an obviously larger viewing space due to the higher resolution. It’s also very light compared to other options, so it’s great for a portable option as well.
It feels plasticky, but the monitor is surprisingly decent when it comes to build quality. The panels are thick and sturdy, and there were no signs of cosmetic defects on its major parts. The stand is firm and stable, so the screen won’t sag or wobble during regular use.
Koorui GP01 has a joystick at the back for easy access to its settings and features. It’s located at the back near the right edge of the display, so it’s accessible even if you don’t directly see it. Other budget models have to make do with OSD buttons, so we’re glad that this has a more up-to-date solution for that.
The stand included in the package offers tilt, swivel, pivot, and height adjustments for your convenience. This upgrade usually adds fifty bucks or more to most monitors, so we’re glad to see it on a product that was made to be as affordable as possible. You can also use VESA mounts, but they’re not entirely necessary for typical setups.
The Koorui GP01’s connectivity layout is rather limited, but that’s understandable since it’s a budget model. It has DisplayPort 1.4 and two HDMI 2.0 slots, so it has more than it needs for basic operation with PC and gaming consoles. It doesn’t have speakers as well, so its only option for audio is a standard 3.5mm jack.
Display and Performance
The Koorui GP01 sports a 24-inch IPS panel with a 2560 x 1440 resolution, a 165Hz refresh rate, and a 1ms boosted response time. The backlight goes up to 350 cd/m2 while the contrast is still at 1000:1. This model doesn’t have HDR certification, but that’s fine since monitors in its class cannot provide convincing HDR anyway.
Smaller 1440p monitors are desirable even if they are considered “niche” since they are basically compact and sharper. You get upgraded visuals and a larger viewing area, so they are perfect for most games and productivity. Some scaling might be necessary, but it’s not something you will not be able to live within the long run.
The Koorui GP01 covered 99% of sRGB and 77% of DCI-P3 for decent color coverage in any situation. It is not the most vibrant, but its dE average of 2.38 is decent for a budget model. Gamers won’t need to calibrate it since it’s already acceptably balanced when the standard preset is used.
Calibrating it improved the dE average to 1.53, which is better and more neutral for all-around use. The downside is that you will need a colorimeter to achieve similar results since copying settings or ICC profiles will not guarantee it. Each panel has minuscule differences, so no two will be identical when it comes to accuracy.
The backlight reached 341 cd/m2 at 100%, so it has enough to fight off a decent amount of glare. Its contrast peaked at 1048:1 at 40% brightness, so it is incapable of deep blacks like VA or OLED types. Its HDR compatibility doesn’t mean a whole lot since it doesn’t have the necessary hardware for it.
Panel uniformity for the test sample wasn’t great since there were backlight leaks on the top edges of the screen. This issue affected dark scenes but is mostly unnoticeable against lighter backgrounds. This can vary with every monitor made due to tolerances, so there are better units out there.
The Koorui GP01’s pixel response time is great since it barely shows any blurring during fast-paced scenes. There are some instances, like in contrasting transitions, where it can still happen, but it’s not a major issue. Using its overdrive sparingly helped, but maxing it out did induce unwanted overshoot.
The Koorui GP01 is compatible with both FreeSync and G-Sync for tear- and stutter-free gaming. Dual compatibility is essential if you want to keep VRR functionality and the monitor while switching to the other GPU brand. Its input lag sits at 4ms at 165Hz, so it is just as good as its premium counterparts in that regard.
Thoughts on the Koorui GP01
The Koorui GP01 is a decent pick if you want a higher resolution in a package that is usually offered with 1080p. It’s sharp and built well, so it doesn’t feel like an ultra-budget monitor at all. It is not perfect when it comes to image quality, but we like how balanced it is compared to other so-called HDR monitors.
It isn’t perfect, but most of the flaws are not deal-breakers since most are expected from an IPS monitor. 24-inch 1440p monitors are often expensive, giving Koorui the perfect excuse to gather more would-be owners under its brand. The GP01 is an excellent solution if you want crisper images in a size that’s usually reserved for regular 1080p screens.
Pros:
- Excellent Price
- Unique Size/Resolution Combo
- Decent Colors and Fast Gaming Performance
Cons:
- Limited Contrast and HDR
- Limited Features
