The INNOCN 27C1U is a 27-inch 4K IPS productivity monitor with a sleek design, excellent ergonomics, and versatile connectivity options, which include a 65 W USB-C PD port capable of receiving video and data from your source, as well as charging its battery. The monitor can be used as a docking station for modern USB-C laptops, with an option to connect the peripherals directly to its USB 3.0 ports. By doing so, you'll only have to connect a single USB-C cable to your laptop to start working, with your laptop's screen extending to the monitor, and the peripherals controlling the laptop. Should you want to connect the INNOCN 27C1U to a secondary source, such as a desktop PC or smartphone, the monitor will allow you to quickly reassign the peripherals to that source. The picture-in-picture and picture-by-picture modes also let you view video signals from both sources at once, and there's a nice option to assign a quarter of the screen to a smartphone for a more natural picture-by-picture experience.

There's nothing you can't do with the INNOCN 27C1U in terms of adjusting its position. The screen can be swiveled, tilted, adjusted in height, and even pivoted in either direction. There's an integrated Gravity Sensor keeping an eye out for screen orientation, and it rotates the picture in Windows as necessary.

In terms of raw performance, the INNOCN 27C1U is somewhat of a mixed bag. Its IPS panel offers very good color and backlight uniformity, a wide brightness range, as well as the terrific sharpness inherent to 27-inch 4K panels. Color accuracy and gamma are greatly dependent on the mode you use it in, and if you're able to calibrate it or not. Decent color accuracy can be achieved by switching the monitor to sRGB Mode. In Standard Mode and Uniformity Mode, it's sub-par. The problem is that while sRGB Mode offers good color accuracy, it also comes with a high gamma (2.39) that's isn't fixable because activating sRGB Mode locks you out of manual gamma adjustment. At the same time, Uniformity Mode fares much better in terms of gamma (2.11), but, as already mentioned, is lacking in terms of color accuracy. The only real solution is a proper hardware calibration of the INNOCN 27C1U, which improves the color accuracy substantially and fixes the gamma, making this monitor a viable choice for more demanding tasks, including some color-critical work.

With all that in mind, the $480 asking price is far too high, as you can get a capable 27-inch 4K monitor, although with fewer features, for around $300. I'd only ever consider buying this monitor with the coupon and discount code applied, as that knocks its price down to a more reasonable $304.
