Can't calibrate monitor when using DisplayPort

[bradc]

Since switching my monitors to DispayPort out, I cannot calibrate them.
I had the color profile calibrated when using HDMI out, but now I cannot change anything. If I select a different profile, or try to calibrate from scratch, nothing changes on the display.

Is anyone else using Displayport having this issue?


I'm on a 2019 MBP running Catalina (10.15.5)
Dual Samsung 24" CF390 monitors (both connected via Displayport to HDMI cables)
Startech USB-C Dock DK30CH2DEP (DisplayLink Manager 1.1.0)

Hello,

Thank you for reaching out!

In MacOS our drivers do not support monitor calibration.
It is planned, but we don't have a timescale for releasing it. There is also a dependency on support in MacOS for this.

Best regards,
Katarzyna

I can calibrate when it's using the HDMI port, but not via Displayport?

It doesn't support clamshell mode.

It won't support unlock with Apple Watch.

This dock retails for over $300 US and it can't do anything more than a $20 adapter!
