Koorui E2412F review: A basic monitor that prioritizes its budget price
Table of Contents
Not every monitor needs to be packed with high-end features, a huge resolution, or an eye-watering price tag. Sometimes, you just need a cheap, simple display that gets the job done. That’s where the Koorui E2412F comes in.
This is a 24-inch VA monitor with a 1080p resolution and a 100Hz refresh rate, giving it a little more speed than your typical budget office display without pushing the price up too far. It doesn’t have the higher resolutions, wide colour gamuts, or gaming-focused features of something like the Koorui 34E6UC, but that’s not really what it’s trying to do. Instead, it’s a straightforward display designed for everyday work, browsing, and some casual gaming.
At its low price, though, there are inevitably some compromises. So, after putting the E2412F through its paces, here’s how it performs.

The Koorui E2412F is just a simple business monitor. Offering a low 1080p resolution but upping the refresh rate, it delivers a slightly improved experience over just 60Hz. But it doesn’t have much more than that; with a rather poor color gamut and accuracy, it does need some calibration to even have a good range, but its poor response time and performance beyond casual usage really limit it to a value display or as a second screen.
- Very inexpensive cost
- A faster refresh rate than basic screens
- Diverse connection options, including audio
- Lightweight and small
- Color gamut and accuracy not great
- Not a uniform display
- Limited brightness range
- Outdated display inputs
Pricing and availability
If you’re looking to pick up the Koorui E2412F, it is a relatively cheap monitor, although availability is somewhat limited. For this particular model, it is available on Koorui’s own site and on Amazon, with a list price of $80/$150.99. In practice, though, it seems to be discounted to under $90 on Amazon most of the time.
Compared to other monitors with similar specifications, it sits firmly at the lower end of the price spectrum and is priced similarly to several competing options. These include the Philips 241V8LB for $79.99, the Samsung S30GD for $124.99, the Sceptre E248W-FW100T for $119.97, and the ViewSonic VS2447M for $89.99.

Design and specifications
The E2412F comes in a rather small box that doesn’t weigh a lot at all. It has a handle and is securely packaged, making it relatively easy to carry around. Inside, the monitor sits between two pieces of polystyrene, with the accessories slotted into the top section.

There isn’t much included beyond the display itself. The accessories consist of the bulky square stand and stem, power adapter, HDMI cable, and a few manuals for the screen.
Unwrapping the monitor reveals a simple design and finish. There is a Koorui logo on the top, while the large bump across the bottom-middle houses the VESA mounting holes and the five control buttons on the left. Those buttons are a rather frustrating way of navigating the monitor compared to the single joystick found on many other displays, and they take some getting used to.
Across the bottom of the middle bump is a single cluster of connectivity. This consists of a single HDMI port, a rather dated VGA port, an audio connector, and a barrel jack for power. Although it doesn’t have an internal power brick, there isn’t one dangling from the cable either. Instead, thanks to the monitor’s 24W power requirement, the power supply is built directly into the plug.

Down the side is a simple white status light, positioned slightly away from your eyeline. It isn’t particularly convenient if you want to quickly glance at the monitor’s status.
Viewed from the side, the monitor showcases its relatively slim 8 mm profile, as well as its tilt adjustment. Ergonomics are limited, with only a -5° to 15° tilt range, so using the VESA mount with a monitor arm could be worth considering. That’s especially true given the stand base itself is a rather large square that takes up a surprising amount of desk space for a monitor of this size.

That just leaves the front of the monitor, which is about as simple as you’d expect. The bottom chin carries the Koorui logo, while a black bezel surrounds the display. The bezels are relatively thin and don’t take up too much of the available screen space.

OSD, settings, and warranty
Having set up the monitor and powered it on, I went through the settings and features available. These are accessed using the various buttons on the back of the monitor, which aren’t labelled from the front. This led to plenty of wrong presses and a few minutes of trial and error before I got used to which button did what.

Once activated, the menu appears across the bottom of the screen, with all the main options visible. The first is the display menu, where you can adjust brightness, contrast, and DCR (dynamic contrast ratio). Beyond that, the selection remains fairly basic, covering language, aspect ratio, input, gamma, volume, and other standard settings.
The more interesting options are the various modes and colour settings. There are several presets that offer different looks depending on what you’re doing. These include Cinema mode, Ebook and EyeSaver modes, alongside options for making the image warmer or cooler.
As for the warranty, the monitor comes with a three-year warranty service. Amazon specifies one year of coverage for the display itself and three years for the other accessories.
Screen testing and performance
After going over the details of the E2412F, I proceeded with testing the monitor. Using our Calibrite sensor combined with DisplayCAL software, I measured its performance across a variety of tests, including colour gamut, accuracy, contrast, brightness, and panel uniformity.

Color gamut
The first test is the colour gamut of the display, which shows how much of the colour spectrum the monitor can reproduce. I checked the coverage from the factory setting and then again after calibration to see whether there was any meaningful difference.

Across the various modes and calibration, the gamut doesn’t change much and remains relatively consistent. In the sRGB spectrum, it reaches around 93% coverage, while Adobe RGB sits at 65% and DCI-P3 at around 68%.
So generally, it’s acceptable for sRGB use, although it still falls short of full coverage. It’s much less capable in the wider colour spaces, meaning this isn’t a monitor I’d recommend for colour-critical work, regardless of calibration.
Color accuracy, contrast, and brightness
Following the gamut testing, I measured the various modes and how they affect the display, looking at white and black levels, contrast, gamma, and overall colour accuracy.
| 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) | 7171K | 0.0439 cd/m² | 2866.5:1 | 2.24 | 4.86 | 2.31 | 125.9 cd/m² |
| sRGB | 6660K | 0.0275 cd/m² | 4812.9:1 | 2.37 | 4.51 | 2.05 | 132.6 cd/m² |
| Standard – Cool | 8644K | 0.0444 cd/m² | 2493.8:1 | 2.67 | 5.34 | 2.32 | 110.8 cd/m² |
| Standard – Warm | 6313K | 0.0444 cd/m² | 2890:1 | 2.03 | 5.14 | 2.29 | 128.3 cd/m² |
| Movie | 7303K | 0.1256 cd/m² | 2762.3:1 | 2.44 | 5.2 | 2.31 | 346.9 cd/m² |
| Eye saver | 4651K | 0.0743 cd/m² | 1653.6:1 | 2.9 | 8.45 | 2.27 | 122.8 cd/m² |
| Calibrated | 6527K | 0.0438 cd/m² | 2740.1:1 | 0.81 | 4.24 | 2.18 | 120 cd/m² |
Firstly, the white level of the monitor out of the box is rather cool, measuring more than 600K above the 6500K ideal. It’s only when the sRGB or warm colour modes are enabled that it gets closer to the target. There is also an even cooler option that pushes the image further into a blue tint, while EyeSaver goes in the opposite direction, producing a noticeably warmer and more yellow image.
Being an LCD VA panel, the black levels and contrast aren’t particularly close to ideal. They’re not terrible, but the backlight does mean the display struggles to produce truly dark areas, leaving blacks looking brighter than they should.
Brightness is another area where the E2412F struggles. At level 0, I could only get the display down to 125 nits, while 100 reached around 373 nits. This gives it a fairly limited brightness range, particularly if you want to use it in a darker room.
As for colour accuracy, most of the default modes sit between 2 and 3 on average. That’s not particularly accurate, but it’s also not disastrous for a monitor in this price range. The maximum deltaE does rise above 4, and often above 5 too. The calibrated mode brings the average down considerably, reaching 0.81, although the maximum remains relatively high at 4.24.
Panel uniformity
I then measured how the panel varies across its surface and how uniform it is. This compares the brightness and colour variation across the display against the centre-most square.
For our E2412F, there is noticeable variation across the panel. Only two squares directly next to the centre sit within the recommended tolerance, with brightness changing by just 5% from the 120 cd/m² target. Most of the remaining panel stays within nominal tolerances, with the average brightness varying between 5 and 8 candela and the colour delta sitting between 2 and 3.
The left side and bottom-right corner are where things become more noticeable, exceeding the nominal tolerances. The maximum brightness variation is primarily above 12%, while the colour delta rises above 4. The bottom-left corner is particularly affected, with variation exceeding 7%.
Viewing angles
I also checked the viewing angles of the monitor. With a reported 178° viewing angle, it should provide a decent view from just about any position. In practice, you can still see the content when moving off-axis, but the image becomes noticeably dimmer and harder to make out.

Gaming performance
Although it is marketed as a business monitor, I still checked how it handled gaming. I ran both Counter-Strike 2 and Cyberpunk 2077 to see what the display could offer outside of basic productivity.

Starting with CS2, the monitor is, of course, rather basic and nothing too flashy when it comes to fast-paced gaming. The 100 Hz refresh rate does at least provide a smoother experience than 60 Hz, although the difference isn’t particularly dramatic. It didn’t present any major visual problems either, with no obvious tearing or artifacting during testing.
As a result, it can work as a cheap office monitor that doubles up for some casual gaming. The biggest issue is the image quality, with Dust 2 looking even greyer and more washed out than usual.
Similarly, in Cyberpunk, the small screen and washed-out colours make the experience less visually impressive than it would be on a more capable display. The 1080p resolution and 100 Hz refresh rate do make sense for lower-end PCs, however, as the lower resolution is easier for less powerful hardware to run. Unfortunately, the weaker contrast and black levels mean it struggles to show off the game’s darker scenes and more impressive visuals.
Response rate
To further check its gaming performance, I used OSRTT (Open Source Response Testing Tool) to measure the display’s response times.
As expected, the E2412F struggles here, particularly when transitioning between certain colours. The average perceived response time is 19.5 ms, while the average complete time is 33 ms. There is one transition from 204 to 255 RGB that takes just 2.7 ms, but many of the other transitions are considerably slower.
The benefit is that it doesn’t overshoot the correct RGB value, with zero recorded across the error rate. However, the slow transitions ultimately result in an average rating of around 57, making response time one of the weaker areas of the display.
General performance and productivity
I then used the monitor for general work and casual use, which is where the E2412F is really intended to be used.
For basic productivity, the E2412F does an OK job. The 100 Hz refresh rate makes the desktop feel smoother when moving windows around or scrolling through documents, although that’s about as far as the benefits go.
The 24-inch size is also something of a limitation. I found myself needing to sit relatively close to the screen to get a good view, while the smaller panel also limits how much content you can comfortably have open at once. It’s not a huge issue for basic tasks, but anyone used to a larger monitor or dual-screen setup will notice the difference.
The limited colour range and accuracy without calibration also mean it’s not particularly suitable for colour-sensitive work. It’s much better suited to basic office tasks, browsing, documents, and general everyday use. At least there are display options aimed at reducing eye strain, although the limited brightness range means it may not be equally comfortable in every lighting environment.
- Panel type: LCD VA
- Resolution: 1920 x 1080
- Refresh rate: 100Hz
- Response time: 1ms
- Panel size: 24-inch
- I/O ports: HDMI 1.4, VGA, 3.5m audio
Conclusion
Overall, the Koorui E2412F is a straightforward, inexpensive monitor that sticks to the basics rather than trying to do too much. Its 24-inch 1080p VA panel is well suited to everyday office work, browsing, and general desktop use, while the 100 Hz refresh rate provides a noticeably smoother experience than a traditional 60 Hz display. It’s also easy enough for lower-end PCs to drive, making it a reasonable option if you’re looking for an inexpensive secondary display or a monitor that can handle some casual gaming.
