Need a desktop 4K monitor with great color reproduction, but not much of a gamer? The Innocn 27C1U is for you, and you don’t need to spend thousands. It is now available for the US market for a price of $400, and is launching in Europe next month. Read on to find out what I thought of the Innocn 27C1U.

Thanks to Innocn, we’re also offering two brand new 27C1U 4K 27″ monitors; one for the US, and one for Europe. You’ll find the entry form at the end of this review.

who is innocent?

Innocn probably isn’t a brand you’ve heard of, so it makes sense to be careful. After all, a monitor is one of the most expensive bits of tech in the home. And if you’re working from home, the screen you’re staring at all day isn’t something you want to spoil. Thankfully, I can confirm that the 27C1U is a great looking display.

Founded in 2014, I suspect Innoken began life as an OEM (original equipment manufacturer: a company that makes products for other companies to rebrand as its own). With over 300 patents to his name, Innocn might just as well just be heavily involved in the research and development side of things.

However, after increasing its production capabilities in recent years, Innocn is now targeting the end consumer market with a range of desktop, portable, ultrawide and gaming-oriented monitors. This is a brand that you will hear more about in the years to come if they can maintain this level of quality.

27C1U Design

The 27C1U has a simple, somewhat generic boxy design in dark gray. As a result, it won’t stand out on your desk for anything other than picture quality. With the stand it measures 24.15 x 21.4 x 7.65 inches (WxHxD) and weighs 12.5lbs (5.66kg).

Four physical control buttons sit on the bottom edge of the monitor. With these you can navigate the labyrinthine menu system, swap input sources, and quickly adjust brightness or volume.

Curiously, there’s also a 20cm ruler built into the base of the stand. I mean… why not? It in no way detracts from the overall and may be useful to some.

Power is provided by a 150W external power brick. This helps keep the weight down, but it also means you have a brick on the floor somewhere. On the other hand, it is also much easier to replace an external power supply than an internal one, so this should help with durability over the long term.

Features and Specifications of Innocn 27C1U

The 27C1U is a 4K UHD monitor, which means it has a maximum resolution of 3840 x 2160. It’s capable of 400 nits (candela/m2), and I found it pretty bright during the typical dull British days. , Lowering it was the only setting I changed in the end, leaving the color profile as the default.

The display uses In-Plane Switching (IPS) LCD technology. It’s generally associated with great color accuracy and wide viewing angles, but it has had a bad reputation with gamers due to perceived slow response times. In today’s IPS panels, this is not a problem. Innocn claims a response time of around 10ms, and of course, I didn’t notice any lag with Twitch gaming titles.

It’s HDR-capable—technically—but only for the HDR 400 “standard,” which corresponds to 400 nits of brightness, and isn’t a strictly defined test criterion anyway. So if you’re serious about HDR, you should look for Dolbyvision or DisplayHDR certifications.

Having said that, I found the colors in the HDR test video to be incredibly vibrant, but not something I’d use regularly.

The 60Hz refresh rate is more than enough for desktop use or casual gaming. However, it doesn’t have FreeSync/GSync support, variable refresh rate, or overdrive mode, so hardcore gamers will likely miss it.

Innocn claims 100% sRGB and 98% DCI-P3 coverage, and includes a printout in the box of calibration lab results. While I have no reason to doubt the claims, I am not equipped to measure color reproduction accuracy. However, colors looked accurate in Final Cut and Lightroom, with natural tones and no banding across the board. The 27C1U box touts it as “monitoring of the art,” and I have to agree.

The 27C1U also has two 5W built-in speakers, but you shouldn’t expect much from them. Sure, it’s better than the speakers built into my Mac Mini, but it wasn’t exactly an lofty goal to beat.


The 27C1U has some standard video connections, and one you might not expect: two HDMI 2.0, one DisplayPort 1.4, and one USB-C. The USB-C port, as well as carrying the video signal inside, can provide up to 65W of power to connected devices. For example, it can be a compatible smartphone or laptop, making it an excellent all-in-one docking station.
