========================
Detailed description：I can use my HDMI to DHMI no issues. However, I would like to use the higher refresh rate through the display port so I purchased an HDMI to Displayport cable and it does not work. The monitor also has a USB-C port and that also does not work. Can I not use these with this Zenbook?
Thanks

Hi there,
Can you specify the monitor model?
Or share the tech spec of it with us.
Thank you.

The monitor is this:

75hz

Hi there,
The Type C port of UX581 is supporting Thunderbolt 3 signal.
And the maximum output is 3840*2160,60Hz.
So you would like to get 75Hz with the Type C port?
How many Hz did you see when you connect the device and monitor by Type C to Type C?
Thank you.
