Unable to select correct resolution when using HP Dock
 

Hi all,

I'm using an HP USB-C dock with DisplayLink on an M4 MacBook Pro with DisplayLink Manager 13.0.0 (build 33) which I think is the latest, and a Dell U3011 monitor connected by HDMI to DVI-D cable.

When I connect my monitor direct to the HDMI port on the laptop, I can select the full resolution and it works:

However when I connect the same HDMI plug into the HP dock, I can't choose that resolution, only a lower one:

This is despite having enabled experimental HiDPI modes in DisplayLink Manager.

Any ideas what the problem could be?

Thanks, Chris.

According to page 5 of the manual for your Dell display --> https://dl.dell.com/manuals/all-products/esuprt_electronics/esuprt_display/dell-u3011_user's%20guide_en-us.pdf the display has a dual-link DVI video input.

According to this DisplayLink knowledge base article (look all the way at the bottom) --> https://support.displaylink.com/know...lution-support dual-link DVI displays are not supported by DisplayLink.
