I have a P40 Yoga attached to an Ultra Dock 3.0 USB. I have/had an HDMI cable coming off the dock to a ViewSonic monitor. I am getting a maximum resoltion of 1920 x 1080 and colors are not displaying correctly or in some cases not displaying at all. I found mention on the ThinkPad site that 4K is only supported via the DP off the dock. So I tried a DP to HDMI cable and that does the same thing. If I plug the monitor directly into the HDMI port on the laptop everything works great.
Why doesn't the dock work as advertised and expected? Is there a different setup required?
