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.
The INNOCN 27M2V is great for most uses. It's best for gaming because it has a fast response time, low input lag with high-frame-rate signals, VRR support, and HDMI 2.1 bandwidth. It also displays deep blacks and has a good local dimming feature that improves the picture quality in dark scenes, which is important for using it in dark rooms. It's great for productivity or content creation because it has excellent ergonomics, decent viewing angles, and high peak brightness. It also displays fantastic text clarity thanks to its 4k resolution.
The INNOCN 27M2V is an excellent 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.
The INNOCN 27M2V is excellent for gaming. Fast-moving objects look smooth thanks to the quick response time, and it has low input lag with high-frame-rate signals, but the input lag increases a lot with 60Hz signals. It also has VRR support to reduce screen tearing and has HDMI 2.1 bandwidth which makes it fully compatible with current-gen gaming consoles. Lastly, it's great for dark room gaming as blacks are deep, and there's minimal blooming when viewing from right in front.
The INNOCN 27M2V is great for media consumption. Its full-array Mini LED local dimming feature helps improve black levels in dark scenes, and there's minimal blooming when viewing it from directly in front. It also gets bright and displays a wide range of colors for a vivid and life-like image. Unfortunately, while it has decent viewing angles, there's more visible blooming when viewed from the sides, and the image fades from really wide angles.
The INNOCN 27M2V is impressive 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. Luckily, it has excellent ergonomics and decent enough viewing angles if you need to share your screen with someone sitting next to you. It also has an accurate sRGB mode and displays a wide range of colors.
The INNOCN 27M2V is great for HDR. While it has a low native contrast ratio, its good full-array local dimming feature helps improve the contrast in dark scenes. There's minimal blooming around bright objects when viewed directly in front, but there's more blooming when viewed from the sides. On the plus side, it easily gets bright enough to make highlights stand out and has a fantastic HDR color volume for vivid colors.
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.

Our unit was manufactured in February 2023; the label is here.
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 watching your favorite shows. 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 spending more on a high-end display like the Samsung Odyssey Neo G7 S32BG75.

The INNOCN 27M2V and the Cooler Master Tempest GP27U are competing 27-inch, 4k monitors that share many of the same features. They both have Mini LED backlighting, and the INNOCN has a better local dimming feature with less blooming because it has 1,152 dimming zones compared to 576 on the Cooler Master. The INNOCN also has a few less bugs as there isn't a noticeable flicker with local dimming on with VRR like on the Cooler Master. However, the Cooler Master has better motion handling.
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 Gigabyte M27U and the INNOCN 27M2V are excellent gaming monitors, but there are a few differences. The INNOCN delivers better picture quality thanks to its improved local dimming feature, as it displays deeper blacks and brighter highlights than the Gigabyte. However, motion looks better on the Gigabyte thanks to its quicker response time, and it has lower input lag with 60 fps signals.
The Samsung Odyssey Neo G8 S32BG85 and the INNOCN 27M2V are excellent gaming monitors with Mini LED backlighting. They're different in a few ways as the Samsung has a higher 240Hz refresh rate, and while it has a higher native contrast, there's less blooming on the INNOCN with local dimming on. The Samsung has lower input lag with 60 fps signals, which is great if you play games at a low frame rate. However, the INNOCN gets much brighter in HDR, especially with real content, and it has wider viewing angles.
The Samsung Odyssey Neo G7 S32BG75 and the INNOCN 27M2V are excellent gaming monitors with Mini LED backlighting. While the Samsung has a higher native contrast, there's less blooming on the INNOCN with local dimming on. The Samsung has lower input lag with 60 fps signals, which is great if you play games at a low frame rate. However, the INNOCN gets much brighter in HDR, especially with real content, and it has wider viewing angles.
The INNOCN 27M2V and the Acer Predator X32 Fbpmiiiiphuzx are both great monitors, but the INNOCN has a few extra advantages. Although they both feature Mini LED backlighting, the INNOCN has double the number of dimming zones as the Acer. This makes the local dimming feature slightly better overall, as there's less black crush, but the Acer has less blooming when viewed from the sides. The INNOCN also makes small highlights get brighter, it has better motion handling, and text looks sharper as it displays text better than the Acer.
The build quality is okay. It's entirely made of plastic which feels somewhat cheap. Unfortunately, there's a small plastic crack at the top of the stand, which you can see in this photo. The stand is also plastic, and the screen wobbles. Unfortunately, the monitor isn't put together well, as the bottom bezel isn't flush with the entire screen, and it moves easily. When rotating the screen into portrait mode, it doesn't rotate the full 90 degrees, so the screen isn't perfectly straight. Luckily, despite some reports online, our unit doesn't have any coil whine issues.
Additionally, we measured the power consumption in different scenarios:
Lastly, we measured the temperature after leaving the monitor on for seven days straight without turning it off. It was around 106°F (41°C) at its hottest point.
The INNOCN 27M2V has excellent ergonomics. The screen is easy to adjust, but when you rotate it into portrait mode in either direction, the screen doesn't rotate a full 90 degrees, so it doesn't sit perfectly straight. While it's hard to notice, it can be annoying if you want the screen level.
The back features a vent-like pattern, and there's also a cut-out in the stand for cable management.
The INNOCN 27M2V has a decent contrast ratio. While it has a low native contrast ratio, its full-array local dimming feature helps improve the black levels. The local dimming isn't extremely effective at improving the contrast with the checkerboard pattern, which is why the Contrast With Local Dimming is lower than expected. Still, it improves the black levels with most content.
For additional info, we also measured the contrast using the TV methodology that doesn't use the checkerboard pattern. The results show that it's about the same as some mid-range TVs like the Hisense U7G.
The INNOCN 27M2V features Mini LED backlighting with 1152 dimming zones, which helps result in a good local dimming feature. It helps improve the picture quality in dark scenes by improving the black levels while maintaining details in bright objects. There's less black crush with the local dimming on than with it off, as you see details in dark areas well. Scenes with small bright objects, like a starfield, look great, and there aren't any uniformity issues. There's minimal blooming around bright objects or subtitles, and even though you'll see more blooming when viewing from the sides, you have to be at a wide angle to notice it. If you want something that doesn't have any visible blooming when viewed from the sides, then check out the Acer Predator X32 Fpbmiiiiphuzx.
Overall, it looks good when viewing from in front, but you may notice some issues if you need to sit at a wider angle. The video above is in SDR with Backlight Contrast on '100', and you can also see what it looks like in HDR here. It performs the same in both, but highlights are brighter in HDR, and you can't disable local dimming in HDR either.
The SDR peak brightness is amazing, and it easily gets bright enough to fight glare from bright sources. Small highlights are dimmer, but other than that, the brightness remains consistent between different scenes. These results are from after calibration in the 'Standard' Picture Mode with the Local Dimming on and Backlight Contrast set to '100'.
If you want small highlights to get brighter, you can disable the local dimming feature in SDR, as 2% windows are 735 cd/m², and other window sizes are around 776 cd/m². Setting Backlight Contrast to its max of '100' also makes it get the brightest, but it isn't significantly dimmer with it set to '0'.
The INNOCN 27M2V has fantastic HDR peak brightness. Most highlights pop, but some small highlights are crushed a bit. It follows the PQ EOTF curve fairly well, as most scenes are displayed at their correct brightness. There's a sharp cut-off at the peak brightness, but this means that it doesn't tone map before your computer does.
These results are in the 'HDR Standard' Picture Mode with the Brightness locked to its max and with Local Dimming on because you can't turn it off in HDR. You must also enable HDR in the monitor's OSD for HDR to work. The 'HDR Standard' mode gets brighter and is more accurate than the 'HDR Movie' and 'HDR Design' modes. Normally we measure the Real Scene brightness using a Blu-ray player, but we had connection issues with it, and it only displayed images in SDR. Instead, we had to measure the Real Scene brightness from a PC, which isn't directly comparable to other monitors because we didn't use the same testing equipment. While we measured a high brightness with the PC, we measured around 750-800 cd/m² most of the time while playing Destiny 2.
The horizontal viewing angle is decent. The image remains consistent if you're viewing from a bit to the side, but it isn't ideal for sharing the screen with a few people as the image becomes inconsistent from wide angles.
The vertical viewing angle is decent. It's good enough if you need to mount the screen above eye level or if you're standing up and looking down at it.
The accuracy before calibration is great in the sRGB picture mode. It locks most colors well to the sRGB color space, and the color temperature is nearly spot-on with the 6500K target. However, the white balance is still off, and gamma follows a flat 2.2 target instead of the sRGB curve. Luckily, the sRGB mode only locks the Gamma and DCR settings, and if you want to use something else, the 'Standard' mode has worse color accuracy and color temperature, as you can see here.
The accuracy after calibration is remarkable. There aren't any noticeable inaccuracies to the colors and white balance. Unfortunately, a bug causes the calibration settings to revert to their default when you switch inputs. You even have to change the Color Temperature and Response Time back to what you had set them before. However, this isn't the case when switching in and out of HDR, as the settings stay the same if you don't change inputs.
The INNOCN 27M2V has a remarkable SDR color gamut. It has near-perfect coverage of both the sRGB and Adobe RGB color spaces, but not all colors are accurate in Adobe RGB, as it oversaturates some colors.
The HDR color gamut is fantastic. It has wide coverage of the commonly-used DCI-P3 color space and the wider Rec. 2020 color space. It tone maps well with both color spaces, but it isn't perfect, as pure white is the worst in each, meaning it doesn't display whites properly.
The reflection handling is decent. It features an aggressive matte screen coating that reduces glare from most light sources, but it struggles from bright sources, like if you were to place it opposite a bright window. Luckily, it gets bright enough to compensate for what it lacks regarding reflection handling.
The INNOCN 27M2V has VRR support to reduce screen tearing, but it has some oddities. With VRR enabled, you can only reach the max refresh rate of 160Hz with AMD graphics cards over HDMI. Over DisplayPort or with NVIDIA graphics cards, you're limited to a 144Hz refresh rate with VRR enabled, but it still reduces screen tearing. For VRR to work, you must enable FreeSync Premium on the monitor. You can reach the max 160Hz refresh rate with those connections if you send a fixed signal instead.

The INNOCN 27M2V has an excellent response time at its max refresh rate of 160Hz. Motion looks smooth with the Response Time setting on 'Normal' as it has a faster total response time and less overshoot than 'Faster' and 'Ultrafast'. While we normally test the response time with VRR enabled, we used a fixed 160Hz signal this time because of the issue of hitting the max refresh rate with VRR on. You can see the results with a 144Hz signal with VRR enabled below. It performs almost exactly like a fixed 160Hz signal, and the recommended overdrive setting is still 'Normal'.

The response time at 120Hz is great. Although turning off the overdrive setting is better because 'Normal' has a slower total response time and more overshoot, motion still looks smooth. However, this means that you may need to change the Response Time setting if the frame rate drops or if you change games. You can also leave it off if you want a set-and-forget mode. Unlike at 160Hz, these results are with VRR enabled.

The response time at 60Hz is great. It's essentially the same results as at 120Hz because the monitor doubles the frame rate when sending 60Hz signals, whether with VRR on or off. Motion looks great, and the recommended overdrive setting is to leave it off.
The INNOCN 27M2V has no optional backlight strobing feature to reduce persistence blur.
The INNOCN 27M2V has low input lag for a responsive feel with high-frame-rate signals. The input lag feels the same even with local dimming enabled, and there isn't a significant difference. However, it's much slower at 60Hz, likely caused by the monitor doubling the frame rate to 120Hz when sending a 60Hz signal.
The Xbox Series X|S works well with this monitor, but you must enable the HDMI override for 1440p @ 60Hz, which also disables VRR. For VRR to work with other signals, you must first ensure FreeSync Premium is enabled on the monitor.
The INNOCN 27M2V supports the full 48 Gbps bandwidth of HDMI 2.1, so your device doesn't need to use compression to reach high-bandwidth signals. Some users have reported online that there are compatibility issues with HDMI 2.0 devices, like DVD players or older gaming consoles, when HDMI Version is set to 'HDM 2.1'. To ensure the best compatibility with older devices, set it to 'HDMI 2.0' instead.
This monitor's USB-C port supports 90W of power delivery if you're using an SDR signal. It's enough to charge many laptops while you're using them, but not enough for power-hungry laptops with dedicated GPU. The power delivery is lower in HDR, as it's advertised for 30W, but we measured 42W of power delivery.
The INNOCN 27M2V has some limitations with macOS. You're limited to fixed 30, 60Hz, or 120Hz signals over USB-C or 30Hz or 60Hz over HDMI. You can enable VRR after setting the refresh rate to 120Hz, but enabling VRR causes flicker. The flicker does calm down after a few minutes, and VRR works without issue at that point, but the VRR implementation is inconsistent and may not always work properly. Sending a fixed 4k resolution also results in image flicker, so you'd need to switch it to 1080p if that bothers you, but that also means you get worse text clarity. If you're using a MacBook, windows return to their original position when waking the laptop up from sleep, and you can also close the lid and continue using it on the monitor.
You can enable HDR and local dimming is automatically turned on, but like with Windows, you need to enable HDR in the OSD for the best performance; otherwise it looks dim. However, HDR flickers a lot with 120Hz signals over USB-C, as you can see here, and there's still some flicker in SDR, but it isn't as aggressive. Luckily, the flicker isn't there with 60Hz signals or over HDMI.
The INNOCN 27M2V has a few extra features, including:
It doesn't have a KVM switch, but there's a USB Switch setting that could potentially be used like a KVM switch. However, there are reports online that setting one of the OSD hotkeys to this effectively bricks the monitor, so we didn't try it. We don't suggest using this setting either, and there's a chance your monitor will stop working.
