INNOCN 27M2V Monitor Review

The INNOCN 27M2V has a simplistic design with a silver metallic finish. It has a bit of a gamer aesthetic on the back, but it isn't overly aggressive, either.

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:

Using the contrast checkerboard pattern
• HDR - Max Brightness: 110W
• SDR - Max Brightness: 80W
• SDR - 100 cd/m²: 37W

Using a MacBook with USB-C
• HDR - Max Brightness: 96W
• SDR - Max Brightness: 103W
• SDR - 100 cd/m²: 45W

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 stand takes up some space, and you need to put all your peripherals in front of it. Unfortunately, it doesn't support the screen well as it wobbles easily.

The INNOCN 27M2V only has four buttons to navigate the on-screen menu and a power button. It isn't as easy to use as monitors with a joystick. The home button serves as a confirmation button when you want to select something, and you can set the three other buttons to hotkeys.

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.

• Contrast 9,269:1
• Native Contrast 655:1

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 INNOCN 27M2V has great gray uniformity. The edges have a pink tint, but there's minimal dirty screen effect in the center.

The black uniformity is incredible as long as you enable local dimming. There's minimal blooming, and blacks are deep. However, disabling local dimming results in low contrast, backlight bleed, and IPS glow.

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 INNOCN 27M2V has an excellent HDR color volume. It displays bright and dark colors well, but its incomplete color gamut limits it.

The INNOCN 27M2V has fantastic text clarity. The 4k resolution and high pixel density help it display sharp text. These photos are in Windows 10, and you can see what it looks like in Windows 11 with ClearType on (here) and ClearType off (here).

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 gradient handling is remarkable. You won't notice any visible banding, even with darker shades. It's advertised as using 8-bit + FRC but still accepts 10-bit signals.

The INNOCN 27M2V has some oddities with its VRR support. Despite having a max refresh rate of 160Hz, you can only reach that with VRR using an HDMI connection with AMD graphics cards, otherwise the max refresh rate is 144Hz. Besides that, it also supports HDMI Forum VRR.

The INNOCN 27M2V has great motion handling with VRR enabled. The 'Normal' Response Time setting consistently performs well across its entire refresh rate range, but there's more overshoot at lower refresh rates. Although we measured up to 144 fps because the max refresh rate with VRR over DisplayPort is 144Hz, 'Normal' still performs the best at 160Hz. The 'Ultrafast' overdrive setting has such a high CAD that it passes the limits of the chart, as you can see here.

The refresh rate compliance is great. The 'Normal' and 'Off' overdrive settings have the best compliance and get better at lower frame rates, but the monitor's response time isn't fast enough to keep up with its max refresh rate. The data has a lot of noise due to the monitor's backlight flicker, but you can see the compliance with charts that smooth out the flicker below.

• 143 fps
• 120 fps
• 100 fps
• 80 fps
• 60 fps

The CAD at the max refresh rate is great. Motion looks sharp, and the recommended overdrive setting of 'Normal' doesn't have any noticeable inverse ghosting. The 'Fast' and 'Ultrafast' settings have too much overshoot that cause inverse ghosting.

The CAD at 120Hz is great. The 'Normal' overdrive setting performs similarly to its max refresh rate, but there's slightly more inverse ghosting. If that bothers you, the 'Off' setting has none, but it also has more motion blur.

The CAD at 60Hz is good. Unlike at higher refresh rates, the recommended overdrive setting is 'Off' because the other settings have too much overshoot, causing inverse ghosting. That said, 'Off' has noticeable motion blur.

The INNOCN 27M2V has no optional backlight strobing feature to reduce persistence blur.

The INNOCN 27M2V has minimal VRR flicker with changing frame rates, which is fantastic for gaming as there isn't anything distracting.

This monitor uses pulse width modulation (PWM) to dim its backlight. It flickers at such a high frequency that you won't notice it, and there isn't any image duplication, either.

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 INNOCN 27M2V works well with the Xbox Series X|S, but you need to enable HDMI overdrive in the console's settings for 1440p @ 60Hz to work, which disables VRR. Keep in mind that the Xbox doesn't support HDR with 1080p and 1440p signals, so this isn't a limitation of 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:

• Contextual Model: Adjusts the color temperature and brightness to make it easier to read text.
• Crosshair: Adds different crosshair presets to give you a competitive advantage while gaming.
• Dynamic Brightness: Changes the brightness based on the content.
• Eyeshield Remind: A blue light filter mode to help reduce eye strain.
• Gravity Sensor: Aims to rotate the layout of the interface as you rotate the screen.
• Light Sensor: Adjusts the backlight based on the ambient lighting of your room.

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.

Unfortunately, the on-screen display is hard to use and not user-friendly. You can set hotkeys for shortcuts, but navigating the menu and adjusting settings is still difficult.
