Innocn 27 inch 4K 27C1U computer monitor review

If you want a monitor for your Mac, let me suggest the 27-inch one that Innocn just launched. It has 4K resolution, offers 1.07B+ colors and high contrast. The screen is suitable for Photoshop, games or television and cinema.

I tested the 27C1U 27-inch 4K+ computer monitor in my home office, and it’s a feast for the eyes. Here’s why I think you’ll agree.

Innocn 27 inch 4K 27C1U computer monitor review

The only external display offered by Apple starts at $6,000. Which means the average consumer has to look for other options. It is certainly true for me.

When shopping for a new display, the Shenzhen Century Joint Innovation Technology Company probably doesn’t immediately come to mind, but its latest addition to the Innocn lineup is definitely worth considering.


A look at the specifications shows that the Innocn 27 inch 4K 27C1U computer monitor offers a high quality screen.

Its resolution is 3840 by 2160, with an aspect ratio of 16:9. The LCD screen has a 1000:1 contrast ratio, so blacks are black and whites are white. A refresh rate of 60Hz ensures there is no lag.

The display can produce over 1.07 billion colors and offers 98% DCI-P3. That’s high, but competing displays that offer 100% DCI-P3 aren’t hard to find.

To ensure that each monitor meets color specifications, they come with their factory color calibration report in the box. Adobe RGB’s average Delta E for my specific monitor is 0.78, for example. Because it’s less than 1, the colors displayed are virtually indistinguishable from what they’re supposed to be.

The Innocn 27C1U’s backlight reaches a brightness of 400 nits, which is enough for a typical office or living room. The image is clear across a wide 178-degree viewing angle, allowing multiple people to enjoy the screen.

Actual performance

Specs can’t tell the whole story. That’s why I used the Innocn 27 inch 4K 27C1U computer monitor in my home office for work and entertainment.

The external display works well when I’m doing image editing. This is when getting the colors right is most important, and that’s good enough for my purposes. The resolution and brightness are more than what I need for my typical task: writing.

All capabilities of the screen come into play when displaying the video. I watched shows from various streaming services and have no complaints about the Innocn 27C1U.

Just to be sure, I also played games on the external monitor using a variety of computers. There was no delay.

I find 27 inches to be as big an external display as I would like on my desk. And it’s a reasonable size for a TV.

Ports, Speakers, and Stand

Although it is by far the most important component, the Innocn 27-inch 4K 27C1U computer monitor is more than the screen.

The most notable feature – or perhaps less noticeable – are the pleasantly thin screen bezels. They measure just 0.33 inches across the top and sides, while the bottom edge measures 0.75 inches.

The case is black plastic. Not that you’re likely to notice because you can see so little of it.

On the back of the Innocn 27C1U are a DisplayPort, a USB-C port, two HDMI ports, two USB 3.0 ports, and a 3.5mm audio jack. That’s about the widest selection you could hope for. I’ve tested games on PC via DisplayPort, iPad via USB-C, and iPhone via HDMI…all without a hitch.

There is a pair of 5 watt speakers in the external monitor. They are capable of emitting between 60dB and 70dB about 2 feet from the front of the screen, according to my tests. That’s enough for video or gaming in a quiet environment. But you might want to use the 3.5mm audio jack to plug in better speakers for movie night.

The Shenzhen Century Joint Innovation Technology Company has put a pleasantly flexible stand on this monitor. It’s height adjustable – the bottom of the screen can go from 2.25 inches to 7 inches off the desktop with just a touch. The screen can also swivel back and forth at a wide angle and tilt up and down slightly.

You can even rotate the screen 90 degrees. And there is a built-in gravity sensor.

I found the base very solid. It holds the screen securely, with little chance of it being knocked over in the event of a major earthquake.

Innocn 27 inch 4K Computer Monitor 27C1U final thoughts

Let’s be clear: if you’re an artist whose livelihood depends on your screen, you should seriously consider Apple’s $5,000 one. But for just about everyone, the Innocn 27-inch 4K 27C1U computer monitor has everything you need. To review the highlights: it looks great, there are plenty of entry options, and the stand is height adjustable.

Whether you’re looking for a work monitor or a mid-sized TV, this is worth a look. Especially now, when it’s on sale.
