Connectivity

Regarding video inputs, the KTC H27T22 is equipped with a pair of DisplayPort 1.2 ports and a single HDMI 2.0 port.


The built-in USB 2.0 port can only be used for firmware updates. It's nice that KTC gave its users the option to update the firmware themselves, as monitor firmware updates can often fix issues with picture quality, pixel response, OSD features not working, and so on. Many monitors several times the price don't offer such an option.


The H27T22 also has a 3.5-millimeter audio output.

Power Consumption

The monitor gets its power from an external 54 W power brick. The power brick is, of course, supplied with the monitor, along with the accompanying power cable.

I've used the Brennenstuhl PM 231 E power meter to determine the monitor's power consumption 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.



The power efficiency of the KTC H27T22 is entirely within expectation for a 27-inch QHD gaming monitor. The graph also shows us a reasonably linear rise in screen brightness relative to the value selected in the OSD. Increasing the brightness by 25 will result in an actual increase of around 80 nits. I rarely stumble upon a monitor as consistent in this aspect as the H27T22, so I have to give credit to KTC for its implementation.
