4K port not working

I’m not able to get my Sceptre C278W-1920R monitors to both work. They don’t work in the HDMI 4K port, and also don’t work from the displayport to DVI or HDMI.

I am running an ASUS Q542U laptop.


Hello Jim,

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

Unfortunately after looking up your ASUS model I do not believe that it will support the 4K HDMI port on our dock as your computer doesn’t seem to mention that it has USB-C DisplayPort Alternate Mode video output capabilities which our dock requires for the 4K to operate. However, the 2K HDMI and DVI/VGA utilize a different technology and just requires you to install the DisplayLink chipset drivers:


Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
