1 monitor in dual setup is extremely yellow tinted

Thunderbolt TBT3-UDC1

Trying to diagnose why 1 of my monitors is extremely yellow tinted when connected to the dock. It does not matter which displayport it is plugged into.

I have a MacBook Pro (15-inch, Late 2016). I have 2 Dell U2515H Monitors.

Hi Mike,

Thanks for posting.

To better isolate the problem, if you swap the DisplayPort cables between the two monitors, does the yellow tint follow the cable or the monitor?

Pending this test, we can explore some of the monitor settings to see if that may help at all. To do this, please use the buttons on the monitor to open to the Color settings section:

  1. Change the Input Color Format to RGB or YPbPr
  2. Try different Preset Modes in Color Settings OSD. Adjust R/G/B value in Custom Color
  3. Change the Gamma setting to MAC

Thanks for giving us a chance to help!

The yellow tint is specific to one monitor, not the cable, when plugged into the dock via a displayport cable. The color is fine on the monitor if it is plugged directly into the laptop via a usb-c to HDMI cable.

For the other suggestions:

  1. Changing the Input source to YpbPr made it look worse.
  2. The Preset Modes were already set to a specific color temperature using a Datacolor SpyderX Pro color calibration device prior to the dock purchase.
  3. Slightly changed tint, but still very yellow.

Thanks for getting back to me.

If you change the Preset Modes setting back to “Standard”, are you still seeing the yellow tint?

Since the other Dell monitor does not have this yellow tint with the same DP cable or DP connections to the dock, this is likely related to the monitor itself. The best path forward will likely involve ensuring the that color currently set on this Dell monitor is tuned to how you prefer.

Thanks!

I was able to solve this issue by re-running my color calibration utility. It appears the profile was tied directly to the port on the monitor so by switching from using HDMI to connect to the monitor to using DisplayPort, the calibration was completely thrown out.

Glad you were able to resolve the issue.

I’ll be closing this thread, but please feel free to open up a new one or reach out to us at support@plugable.com if you have any additional questions or concerns.

Thanks!
