U2421HE, USB Type-C, charge Samsung Galaxy Note 9

I have a mobile phone (Samsung Galaxy Note 9) that has a USB-C charging port. The charger says Output "9.0 V == 1.67 A or 5.0 V == 2.0 A". Can I charge my Samsung phone from the U2421HE using the provided USB Type-C (C to C) cable?

@Chow SY  The manual for the U2421HE here says this about its USB-C input port: USB PD 20 V/3.25 A, 15 V/ 3A, 9 V/3 A, 5 V/3 A.  So yes, you can, because the USB-C port supports both 5V and 9V and can provide even more power than your phone's charger.  If your phone can't actually use that extra power, it won't.  You won't damage anything by connecting it to a source that can offer more power than the device being charged wants to use.  But sometimes phones support using more power than the charger included by the vendor.  And actually if your phone supports video output from its USB-C port AND you used a USB-C cable that actually supported video (rather than one that only supported charging and USB 2.0 data), you would even be able to use the display as a display for your phone.  The USB-C cable provided with the display would definitely support video.
