The INNOCN 27M2V is a 27-inch, 4k monitor with Mini LED backlighting. Competing mainly with the Cooler Master Tempest GP27U, it has 1,152 local dimming zones to help improve the picture quality in dark scenes and make highlights brighter compared to monitors that don't use local dimming. While this is one of its main features, it's designed with gaming in mind, as it has a 160Hz refresh rate, variable refresh rate (VRR) support, and HDMI 2.1 bandwidth for console gaming. It also has a few extra non-gaming features, like a USB-C port that supports DisplayPort Alt Mode with 90W of power delivery.
Our Verdict
The INNOCN 27M2V is good for PC gaming. Fast-moving objects look sharp thanks to the quick response time, and it has low input lag at high refresh rates, but the input lag increases a lot with 60Hz signals. It also has VRR support to reduce screen tearing and a 160Hz refresh rate. Lastly, it's great for dark room gaming as blacks are deep with local dimming enabled, and there's minimal blooming when viewing from right in front.
- 160Hz max refresh rate.
- Fast response time across VRR range.
- Low input lag with high-frame-rate signals.
- Good local dimming feature.
- VRR only works up to 144Hz with most connections.
- Input lag increases with 60Hz signals.
The INNOCN 27M2V is excellent for console gaming. With a high 4k resolution and HDMI 2.1 bandwidth, it can take full advantage of modern gaming consoles. Motion looks sharp thanks to its fast response time at 120Hz and 60Hz, and while it has low input lag for a responsive feel at 120Hz, it increases at 60Hz, which is disappointing for playing reaction-based games. In terms of picture quality, it offers realistic and vivid images thanks to its high peak brightness and good local dimming feature.
- Fast response time across VRR range.
- Low input lag with high-frame-rate signals.
- Good local dimming feature.
- HDMI 2.1 bandwidth.
- Input lag increases with 60Hz signals.
The INNOCN 27M2V is an impressive office monitor. It easily gets bright enough to fight glare in a well-lit office, and it has decent reflection handling too. Text looks sharp thanks to its 4k resolution and high pixel density. Its excellent ergonomics make it easy to adjust, and it has decent viewing angles, which is important if you constantly need to share the screen with someone else.
- Bright enough to fight glare.
- Excellent ergonomics.
- Decent viewing angles.
- Fantastic text clarity.
- Some issues with macOS.
- Some build quality problems.
The INNOCN 27M2V is very good for content creation. Its 27-inch screen is big enough for multitasking, and its 4k resolution helps result in a high pixel density and fantastic text clarity.

It also has an accurate sRGB mode and displays a wide range of colors.
- Bright enough to fight glare.
- Excellent ergonomics.
- Fantastic text clarity.
- Great image accuracy in SDR.
- Some issues with macOS.
- Some build quality problems.
The INNOCN 27M2V has fantastic brightness. It easily gets bright enough to fight glare in a well-lit room, and it also makes highlights pop in HDR.
- Bright enough to fight glare.
- Fantastic HDR peak brightness.
The INNOCN 27M2V has a great overall response time. It has a fast response time that makes motion look smooth across its entire VRR range, but there's still a bit of blur and inverse ghosting.
- Fast response time across VRR range.
The INNOCN 27M2V is good for HDR. It has a good local dimming feature that helps improve the contrast in dark scenes, and it also makes small highlights really pop against dark scenes. Its HDR color volume is also excellent, so it displays bright and dark colors well.
- Good local dimming feature.
- Minimal blooming when viewed from directly in front.
- Displays wide range of vivid and bright colors.
- Blooming is more visible when viewed from the side.
- Some tone mapping issues, particularly with white.
The INNOCN 27M2V has okay SDR picture quality. It has a low native contrast ratio without local dimming enabled, and there's clouding in dark scenes.
- Displays wide range of vivid and bright colors.
- Low native contrast ratio.
The INNOCN 27M2V has great color accuracy. Its dedicated sRGB mode results in great accuracy, but it doesn't limit all colors to the sRGB color space as some are oversaturated. You would need to calibrate it for the best accuracy, but it has great gray uniformity that keeps the image consistent across the entire screen once you do.
- Great image accuracy in SDR.
- Great gray uniformity.
- Some colors are oversaturated in the sRGB mode.

Differences Between Sizes And Variants
We tested the 27-inch INNOCN 27M2V, the only variant of this model. It's also available in a 32-inch size as the 32M2V, and there are other 4k monitors available from INNOCN, but the results aren't valid for those other monitors.
| Model | Size | Panel Type | Resolution | Refresh Rate | Dimming Zones |
|---|---|---|---|---|---|
| 27M2V | 27" | IPS | 4k | 160Hz | 1,152 |
Our unit was manufactured in February 2023; the label is here.
Popular Monitor Comparisons
On paper, the INNOCN 27M2V is one of the most well-rounded monitors we've tested, as it has a good local dimming feature, high peak brightness, and extra gaming features. While it isn't exceptional at anything, it's versatile for different uses, like if you want to use it for gaming, productivity, and editing. It offers great value if you can find it for cheaper than other high-end 4k monitors. However, it has some drawbacks, like its cheap build quality and increased input lag with 60Hz signals. If you play games at a high frame rate, this isn't an issue, but if you think that will bother you, it might be worth considering another high-end display like the Samsung Odyssey Neo G7 S32BG75.

The INNOCN 27M2V and the MSI MPG 274URDFW E16M are both 4k Mini LED gaming monitors. While they each have a native 160Hz refresh rate, the MSI has a dual-mode feature to boost the refresh rate to 320Hz with a lower 1080p resolution, which the INNOCN doesn't have. They also both have 1,152 dimming zones, but the local dimming feature on the INNOCN results in much better picture quality with less black crush and haloing. The MSI has a few advantages for gaming, though, as it has lower input lag at 60Hz, leading to a more responsive feel with lower-frame-rate sources, like consoles.
The Acer Nitro XV275K P3biipruzx and the INNOCN 27M2V are similar 27-inch, 4k monitors with Mini LED backlighting. There are a few differences between them as the INNOCN 27M2V has a slight advantage in picture quality because it has a superior local dimming feature with more dimming zones and gets brighter, too. They each have similar motion handling, but the INNOCN has a slight advantage because it maintains its sharp motion handling better at lower refresh rates. That said, the Acer delivers more accurate colors, making it the better choice for office use and content creation.
The INNOCN 27M2V and the LG 27GP950-B are both 4k, 27-inch gaming monitors, and while they're both excellent for gaming, the INNOCN delivers better picture quality. This is because it has a much better local dimming feature that helps result in deeper blacks and gets much brighter in HDR, too. The INNOCN also has a few extra features the LG doesn't have, like a USB-C port. On the other hand, the LG has a few less bugs as its VRR support works up to 160Hz with any type of connection, it has lower input lag with 60 fps signals.
The LG 27GR95UM-B and the INNOCN 27M2V are 4k gaming monitors with Mini LED backlighting and similar features. However, there are a few differences in performance, as the INNOCN has a better local dimming feature, more accurate colors, and better motion handling. However, the LG has a lower input lag at 60Hz, making it the better choice for gaming at that refresh rate.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
