Symptoms

This issue occurs with the following configuration:

  • A daisy chain monitor MST setup
  • Any monitor with no Display Stream Compression (DSC) supported is the first monitor in the chain
  • A Dell U2723QE, U2725QE, or U3225QE with High Dynamic Range (HDR) enabled is the second monitor in the chain

The problematic setup is an NVIDIA Quadro card connected over DisplayPort 1 with MST to a monitor that does not support DSC. The MST DisplayPort is connected to a Dell U2723QE, U2725QE, or U3225QE HDR-supported monitor and is turned on.

The monitor either flashes with a bright light, has video corruption, or has a black screen.

Affected Monitors:

  • Dell U2723QE
  • Dell UltraSharp 27 4K Thunderbolt Hub Monitor U2725QE
  • Dell UltraSharp 32 4K Thunderbolt Hub Monitor U3225QE

Cause

A compatibility issue with the NVIDIA card causes this behavior.

Resolution

The following workaround setups can be used to fix this behavior:

  • Connect the monitors to the DisplayPort ports instead of using a daisy chain monitor (MST) setup.
    • From the NVIDIA Quadro card, connect the DSC-unsupported monitor to DisplayPort 1.
    • From the NVIDIA Quadro card, connect the Dell U2723QE, U2725QE, or U3225QE HDR-supported monitor.
  • In the daisy chain (MST) setup, connect the HDR-supported monitor as the first monitor. Connect the DSC-unsupported monitor after that monitor.
