Connectivity

In terms of video inputs, the INNOCN 40C1R has a pair of HDMI 2.0 ports, DisplayPort 1.4, and a USB Type-C port. If you use the USB Type-C port for video, you'll be limited to a 60 Hz refresh rate. Using HDMI 2.0 inputs limits you to 100 Hz at native resolution (3840x1440) or 120 Hz if you lower the resolution to 2560x1440. The only interface that can offer a full 144 Hz refresh rate at 3840x1440 is the DisplayPort 1.4.


The USB Type-C port is more than just an ordinary video input. It also delivers a whopping 90 W of charging power to any connected device, such as your smartphone or laptop. Unfortunately, INNOCN didn't include any USB Type-A downstream ports, which we could have used to connect our peripherals in order to have the monitor act as a handy docking station. The absence of regular USB ports won't be seen as a big deal to gamers, but for productivity, the 40C1R will leave you wanting more. It's an odd omission for a monitor that's marketed as a versatile multipurpose product.


The INNOCN 40C1R also has a 3.5-millimeter audio output to route the sound to your active speakers or headphones. You can also use the integrated speakers, but their quality is completely sub-par for anything other than perhaps an occasional YouTube video while on a break in your cubicle.

Power Consumption

The power supply unit is integrated, so there's no external power brick we need to deal with. A simple IEC power cable will be enough to power the INNOCN 40C1R.

I've used the Brennenstuhl PM 231 E power meter to determine the power consumption of the monitor at various brightness levels, as well as in Power Saving mode, which it enters as soon as the PC goes to sleep. My power consumption measurements are summed up in the chart below. They've been made after resetting the monitor to factory defaults.



Compared to a 34-inch ultrawide monitor, the INNOCN 40C1R has noticeably higher power consumption. On average, it uses around 9 W more power than a 34-inch ultrawide when set to the same measured brightness, and its power consumption goes up to 63.4 W when the brightness is pushed as far as it can go. Granted, at that point, the 40C1R has an above-average brightness of 384 cd/m², which remains out of reach for many mainstream gaming monitors. With adjusted settings, the panel can be even brighter, coming close to the 500 cd/m² mark listed in the technical specifications.

The graph also illustrates that the brightness adjustment scale is anything but linear. The brightness rises slowly at first, but gains around 100 cd/m² of actual brightness from the 75 to 100 brightness setting in the OSD. In other words, when adjusting it past the 75 mark, you have to be extra careful as small steps result in noticeable changes in actual screen brightness. While somewhat annoying, that shouldn't be a dealbreaker for anyone.
