There is a USB-C type port on this laptop and I purchased a portable monitor that requires a USB-C type connect. Went I connect I get the error "no signal". I also get an error suggesting I use an alternative port like the DisplayPort which I purchased a USB-C type converter to DisplayPort and it did not work and provided no errors. I have also reviewed the MS support site ->https://support.microsoft.com/en-us/help/4012609/windows-10-fix-usb-c-problems#connectionlimited. All drivers installed successfully, is there an issue with this port?

It's an AOC USB-C monitor (http://us.aoc.com/product_feature.php?id=96)

You have all these inputs:
INPUTS
VGA
DVI-D
Dual-Link DVI
HDMI
HDMI 1.4
HDMI 2.0
HDMI (MHL)
Display Port 1.2
USB Type-C
And I believe the USB-C is for power not video input. Very cool device but may need to be connected to the DP port directly.

I purchased a PPA Int'l USB Type-C to DisplayPort Cable and I get nothing. The monitor doesn't even power on as it did with the included cable(with this cable monitor powered up, but then displays no signal). Maybe I can research other DisplayPort cable converters(all may not be the same). I know the DisplayPort works on the laptop because I use it for my non-portable monitor.

The USB-C I believe is for power input and then in addition you need to connect a video data cable: HDMI, VGA or DP. If you are running a USB-C to DP converter off the laptop into the monitor you are not giving it either power or display signal as the USB-C on the laptop does not put out a display signal and the DP port on the monitor does not receive power. The included cable I am sure is just like a cell phone charging cable. A USB to USB-C cell phone charging cable would likely work for power.

Think I'm getting to the conclusion that I purchase a portable monitor with the understanding that the USB-C type would support 😞 Sounds like I have a new portable monitor until I get another laptop which is non-basic USB C-Type.
