Product: HP USB-C Dock G5
Operating System: Microsoft Windows 10 (64-bit)

My setup will not do 4k at 60hz, what the HDMI cable did do tho vs an older hdmi cable was it was able to turn on HDR.  But other than that, can the G5 docking station output 4k at 60hz?  We already know it can do 4k 30hz.  

 

EliteBook 840 G6 i5-8365U, USB-C Dock G5, Hdmi high speed 4k 60hz cable. 

 

For refence I even tried some new "8k" cables which do 4k 120hz and it was the same result, 4k 30hz only.

So it says Apple on one display on a DP 1.4 is UHD@60hz .  I've tried using a displayport to hdmi adapter and still only get 30hz at 4k.

I have a Club 3d display port to hdmi adapter coming (not the one capable of 4k120hz tho), hopefully I can use the DP and finally get 60hz.

 

I finally figured it out, I had to go to the BIOS and check the box for: Enable High Resolution mode when connected to a USB-C DP alt mode dock this reduces the usb speed to 2.0.  I dont need super fast usb speeds so I'm good.

4k 60hz now works by doing this.
