What we want to ask is - if we connect computer to a monitor which has usb-c signal and charging capability at the same time  - will it work with this machine?

What do you mean? If I plug in monitor that supports both video and power delivery via usb-c cable the laptop wouldn't be able to charge? Or you just ment that for simultaneous charging and video output one should use appropriate type-c hub or monitor that supports not only video output but power delivery as well?

All it means is you need a USB-C Hub which supports power delivery and Displayout to do both at the same time. The whole point of USB-C is to be able to use a single hub for all your connections anyway. I don't especially want the laptop to be more expensive because the manufacturer put a display out on a second USB-C port.
