Below the rear of the monitor is a DC input from the included external power supply, two USB-A 3.0 ports, a USB-B 3.1 input, a USB-C port with 65W of power delivery, a single DisplayPort 1.4, two HDMI 2.0 ports, and finally a 3.5mm jack. The two 5W integrated speakers are pretty good compared to some competitor screens out there, but you'll want to use your own audio gear for serious work.
Connecting the monitor to a Windows 11 testbench, I was able to check the out-the-box calibration of the INNOCN 27C1U since this is marketed for creative use on a budget. Being an IPS panel, I was expecting solid results and was only slightly disappointed. Using a display calibration tool, it reported in at 97.8% Adobe sRGB, 92.1% Adobe RGB, and 92.6% DCI P3.
After calibrating the INNOCN 27C1U, I was able to achieve even better color reproduction. After a few minutes, we managed 99.8% Adobe sRGB, 93.7% Adobe RGB, and 94.7% DCI P3. It's a shame since such calibration from the factory would have made this a real underdog in the creative display market.
