Koorui G2412V review: Budget by design, budget by price
Table of Contents
Not every gaming monitor needs to come with a huge price tag or a long list of high-end features. There are plenty of cheaper displays that focus on getting the basics right, while still offering a few features that make them suitable for gaming. That’s where Koorui has carved out a place for itself, with a range of affordable monitors aimed at different types of users.
The Koorui G2412V is one of those more budget-focused options. It’s a 24-inch 1080p gaming monitor with a 180Hz refresh rate, giving it a surprisingly high refresh rate for a display at this price. Beyond that, though, the specifications are fairly basic, so I put it to the test to see whether the high refresh rate is enough to make the G2412V a worthwhile gaming monitor.
- Panel type: LED VA
- Resolution: 1920 x 1080
- Refresh rate: 180 Hz
- Response time: 3ms
- Panel size: 24-inch
- I/O ports: HDMI 1.4, VGA
Coming in at around the $100 mark, the Koorui G2412V offers a rather fast and simple monitor design. It provides a good feel to anything on screen, even if the color coverage and accuracy aren’t exactly great. It also has a poor response rate and rather limited and outdated connectivity. But with all that, the low price and speed do give it a good appeal for entry-level gaming and saving a buck towards other hardware.
- Very inexpensive pricing
- Fast and smooth-looking refresh rate
- Ok panel uniformity
- Good design and takes up little space
- Poor color gamut
- Not great response rate
- Limited and outdated connectivity

That’s firmly towards the cheaper end of the gaming monitor market, although there are several similarly priced alternatives. These include the Sansui for $105.99, the AOC C24G42E for $119.99, the Dell SE2426HG for $99.99, and the Samsung G30D for $199.99.
The G2412V therefore sits in a competitive part of the market, with its 180Hz refresh rate being one of the main things it has going for it. The question is whether the rest of the display can match.

Design and specifications
Much like the Koorui E2412F, the G2412V comes in a small and lightweight box that can easily be carried by one person. There’s even a handle on the top, making it convenient to move around without too much effort.
The packaging is also reusable, with the box closing without needing to be held together with tape. Inside, the monitor is surrounded by polystyrene, while the accessories are packed into the top section.
There isn’t much included with the monitor, although that’s not particularly surprising at this price. You get the disassembled stand, an HDMI cable, the power cable, and a few manuals.

Taking the monitor out of the box reveals a very simple, square design with little in the way of visual flair. The Koorui logo sits in the centre of the top section, while the large bump across the lower portion houses the VESA mounting holes and five control buttons on the left.

The buttons aren’t the most convenient way to navigate the monitor, particularly compared to the joysticks found on many modern displays. They are usable, but the lack of a joystick does make navigating the settings feel a little more cumbersome.
The connectivity is found underneath the raised section on the left. It’s fairly limited and somewhat dated, with a single HDMI 1.4 port, VGA, and a barrel-style DC power connection. The stand connects in the centre and slides into place relatively easily.
The stand itself is small and lightweight, which contributes to the monitor’s overall low weight. The plastic construction also gives the G2412V a fairly basic, budget feel.

Looking at the monitor from the side, you can see just how little depth the main panel takes up. The central bulge does add some extra thickness, while the two-pronged stand protrudes surprisingly far from the back of the monitor for such a small display.
Ergonomic adjustment is also limited, with only -5° to 15° of tilt available. There’s a small power indicator along the edge of the display, too, showing when the monitor is switched on.

From the front, there’s similarly little to talk about. The large chin across the bottom houses the Koorui logo, while the relatively thin bezels leave a small border around the active display area. Overall, it’s a very functional design that keeps things simple rather than trying to make the G2412V stand out.

OSD, settings, and warranty
Once the monitor was powered on, I went through the settings and features available through the on-screen display. Thankfully, the buttons correspond to the options shown on screen, so you don’t have to remember which physical button does what. This makes navigation considerably easier than it initially looks.

The first menu provides access to some quick settings, including the display output if automatic selection isn’t working as intended. From there, you can adjust brightness, contrast, and dynamic contrast range (DCR).
There are also more detailed display settings, including hue and saturation controls, adaptive sync, and gamma adjustment. The colour menu provides presets ranging from cooler to warmer tones, as well as a user mode for manual adjustment.
The final sections cover the various picture modes, which change the monitor’s colour and image settings, alongside the general OSD options and input selection.
As for the warranty, the G2412V comes with three years of coverage, which is a decent amount of protection for a monitor at this price.
Screen testing and performance
After going through the monitor’s specifications and settings, I put the G2412V through our usual testing process. Using our Calibrite sensor alongside DisplayCAL software, I measured colour gamut, accuracy, contrast, brightness, and panel uniformity across the various display modes.

Color gamut
Starting with colour gamut, I measured how much of the available colour spectrum the monitor can reproduce. I checked its coverage of the sRGB, Adobe RGB, and DCI-P3 colour spaces to see how capable the panel is across each.

The G2412V is fairly limited in its colour coverage. At its best, the monitor achieved 91% sRGB coverage, 74% Adobe RGB, and 76.8% DCI-P3.
The latter two figures are particularly limited, while even the 91% sRGB coverage falls short of full coverage. That’s not necessarily a major issue for a budget gaming monitor, but it does mean the G2412V isn’t particularly well suited to colour-critical work.
Color accuracy, contrast, and brightness
Colour gamut is only part of the story, though. A monitor can reproduce a wide range of colours, but that doesn’t necessarily mean it displays them accurately. I therefore tested the accuracy and overall balance of the G2412V across its different presets.
| White | Black | Contrast | Average deltaE*00 | Max deltaE*00 | Gamma | Brightness | |
|---|---|---|---|---|---|---|---|
| IDEAL | 6500K | 0/m² | infinity:1 | 0 | 0 | 2.2 | |
| Standard (out of the box) | 6981K | 0.0309 cd/m² | 3926.8:1 | 3.51 | 8.26 | 2.27 | 121.4 cd/m² |
| sRGB | 6643K | 0.031 cd/m² | 3904.1:1 | 3.71 | 8.37 | 2.27 | 121.1 cd/m² |
| FPS | 8372K | 0.0301 cd/m² | 4006.4:1 | 3.65 | 9.17 | 2.2 | 120.7 cd/m² |
| Movie | 6962K | 0.03 cd/m² | 3956.5:1 | 3.48 | 8.16 | 2.27 | 118.8 cd/m² |
| Calibrated | 6481K | 0.032 cd/m² | 3748.3:1 | 0.93 | 2.98 | 2.21 | 119.9 cd/m² |
Out of the box, the display is noticeably cool, measuring around 480K above the 6500K target. The other modes are similarly cool, with FPS mode pushing even further towards a blue tint. The sRGB mode gets considerably closer to the target at 6643K.
The black levels aren’t particularly impressive either. With the backlight behind the LCD panel, the display struggles to produce truly dark blacks, with the best result reaching 0.0301 cd/m². This contributes to some visible lightness in darker areas and means the monitor doesn’t have particularly deep blacks.
Contrast, on the other hand, is one of the stronger areas of the panel. It reaches around 4000:1 across the different presets, while gamma remains close to the 2.2 target.
Colour accuracy is less impressive. Average deltaE sits above 3.5 across all of the standard presets, while maximum deltaE goes above 8. That means there is a noticeable difference between the intended and displayed colours, particularly in some of the more extreme results.
Calibration makes a considerable difference, however. The calibrated mode brings the white point down to 6481K and gamma to 2.21, while average deltaE drops below 1 and maximum deltaE falls below 3. If you have access to calibration equipment, there’s therefore a significant improvement to be made.
Brightness reached 290 nits at 100% in my testing, which isn’t particularly high but should be sufficient for most indoor environments. At the other end of the scale, 0% brightness dropped to just above 40 nits.
Panel uniformity
Next, I checked the uniformity of the panel, comparing the brightness and colour variation across the screen against the centre.
Overall, the G2412V performs reasonably well here for a budget display. A good portion of the panel falls within the recommended tolerance, while most of the remaining areas sit within nominal tolerance.
The main exception is the bottom-left corner, where brightness variation exceeds 7%. The left side of the display is also one of the more noticeable areas for variation, although the average deviation across the panel remains around 5%.
At its maximum, the panel deviates by around 12% from the nominal value. That’s not perfect, but overall the G2412V does a reasonable job of maintaining consistency across the screen for a monitor at this price.
Viewing angles
With the monitor set up and powered on, I also checked its viewing angles. Koorui rates the panel at 178°, and while the display does become noticeably dimmer as you move further off-axis, the image remains visible even at fairly extreme angles. In normal use, this shouldn’t cause too many problems, although you’ll obviously get the best image when sitting directly in front of the display.

Gaming performance
The 180Hz refresh rate is arguably the main reason to consider the G2412V, so I put it through its paces in both Cyberpunk 2077 and Counter-Strike 2.

Starting with Cyberpunk 2077, the jump to 180Hz is immediately noticeable compared to a standard 60Hz monitor. The game feels smooth and responsive, and the higher refresh rate suits the fast-paced action well.
However, the rest of the panel doesn’t quite have the same impact. At 24 inches and 1080p, there isn’t a huge amount of screen real estate, although the lower resolution isn’t particularly problematic at this size. The bigger issue is image quality, with the LCD panel’s relatively light blacks taking away from darker scenes.
As a result, Cyberpunk doesn’t look quite as impressive as it does on a higher-end display, despite the smoothness provided by the 180Hz refresh rate.
Counter-Strike 2 is a different story. Image quality isn’t nearly as important here as frame rate, refresh rate, and responsiveness, which is where the G2412V makes more sense. The 180Hz refresh rate gives the game a noticeably fast feel and provides plenty of headroom for reacting to enemies as they appear on screen.
The 24-inch size can actually work in its favour here, too. Sitting a little closer to the display makes it easier to take in everything happening on screen, while the high refresh rate makes movement feel considerably smoother.
Response rate
I also used our Open Source Response Testing Tool (OSRTT) to measure the monitor’s response times, checking how quickly it transitions between different RGB values and how accurately it does so.
The G2412V isn’t particularly quick here. I measured an average initial response time of around 14.4ms, with a completion time of 27ms and a perceived response time of 14.4ms.
Some of the higher-value transitions are faster, but overall, the panel’s response times don’t quite match what you’d ideally want from a 180Hz gaming monitor.
One positive is that the monitor keeps its error rate under control. It doesn’t overshoot the target values, so although the transitions are relatively slow, the display does eventually reach the correct colour without introducing significant inverse ghosting.
General performance and productivity
I also used the G2412V for more general tasks, including browsing, documents, and everyday desktop use.

For basic productivity, it gets the job done without offering anything particularly special. The 24-inch size and 1080p resolution do limit how much content you can comfortably fit on screen, particularly if you’re sitting further away or trying to use it as your only display.
The 180Hz refresh rate is useful here, though. Windows feels noticeably smoother when scrolling through webpages, moving windows around, and navigating the desktop, even if you don’t need anything close to 180Hz for basic office work.
The limited colour gamut and accuracy also mean this isn’t a monitor I’d choose for colour-critical work. For general office tasks, browsing, documents, and everyday use, though, it does what it needs to.
The simple construction and VESA mounting support also make it an easy display to incorporate into a multi-monitor office setup, while the 180Hz refresh rate gives it some gaming ability when you’re finished working.
- Panel type: LED VA
- Resolution: 1920 x 1080
- Refresh rate: 180 Hz
- Response time: 3ms
- Panel size: 24-inch
- I/O ports: HDMI 1.4, VGA
Conclusion
Overall, the Koorui G2412V is a budget gaming monitor built around one particularly appealing specification: its 180Hz refresh rate. At 24 inches and 1080p, it isn’t trying to compete with larger, higher-resolution displays, but the high refresh rate gives it a smooth and responsive feel in games such as Counter-Strike 2. The 1080p resolution also makes it relatively easy for lower-end gaming PCs to take advantage of that refresh rate.
There are some clear compromises, though. Colour coverage is limited, particularly outside of sRGB, while the out-of-the-box colour accuracy is fairly poor. Calibration makes a significant improvement, but that’s obviously not something every buyer will have access to. The panel’s black levels also leave darker scenes looking lighter than they should, while the response times are relatively slow for a monitor advertised around its 180Hz refresh rate.
