Anker PowerExpand - 4k@60Hz with MBP 2018 15"?


today I got a “Anker PowerExpand 8-in-1 USB-C PD 10 Gbps Data Hub - Model A8383” and regarding to the german Amazon-site to this product: my MacBook Pro 2018 (15") this adapter is able to do 4K@60Hz:


  • Für eine Auflösung von 4K@60Hz bitte prüfen, ob das Gerät 4K@60Hz unterstützt. Hier einige Beispiele für Kompatibilität mit 4K@60Hz:

MacBook Pro 15’ 2018 / 2019

which translates to:


  • For a resolution of 4K@60Hz please check if the device supports 4K@60Hz. Here are some examples of compatibility with 4K@60Hz:

MacBook Pro 15’ 2018 / 2019

But when I connect it via HDMI to my LG Ultra HD display, I only get 4K@30Hz. I can exclude the HDMI-cable and also the HDMI-Port of the display (which is able to receive 4K@60Hz) because with my GTX1070 on my Desktop-PC everything works fine.

This there a driver I need to install or do I need to set some configs on my MBP?

Btw.: I have installed the latest Mac OS X: 10.15.6
Also inside this MacBook Pro (15-inch, 2018) are:
2,2GHz 6 Core Intel Core i7
32GB 2400Mhz DDR
Radeon Pro 555X 4GB
Intel UHD Graphics 630 1536 MB
