ASUS M7600QC no picture over USB-C

Hello!

I got ASUS M7600QC-L2155W, L2155W is a sub model, but as I can see all M7600QC have display signal output over usb-c cable:

Now, on two monitors; Dell P2719HC and MSI Summit MS321UPDE fairly new and new, fully operational, I can't get image over usb-c, only over HDMI. Those things should be straightforward so I got no idea where to start looking for solution. I’m using cables that came with monitors.

Edit: Also, specs claim that it has power delivery over USB-C, but no charging happens that way, only on AC. Both monitors see that USB-C cable is inserted.

Anybody got some idea?

Confirmed by the technical unit, the USB TYPE-C of M7600QC only supports data transmission. 

Sorry for any inconvenience it may be caused.

Hmm, big reasons to buy laptop were oled screen and power/price ratio, small ones were quality case, fingerprint and usb-c with display signal. Not like ASUS...
