Sorry to hear that wasn’t of any help.
Looking further into the user manual for this ViewSonic monitor, I’m seeing that the manufacturer actually doesn’t support 2560x1440 resolution via the HDMI connection on Windows hosts – only the DVI and DisplayPort inputs support 1440p.
I wonder if this has anything to do with this problem. What if you connect the ViewSonic monitor to the “HDMI 4K” port on the dock, then drop the resolution of the display to 1920x1080 in your Windows Display settings (Right-click on Desktop, select Display settings)?
Thank you!
