Quick answer: Many USB, Thunderbolt, or DisplayPort docking setups can block DDC/CI traffic between Windows and a monitor.

Step-by-step instructions

Connect the monitor directly to the computer.
Enable DDC/CI on the monitor.
Compare app detection in both connection modes.
Review dock firmware and driver updates.

Why this matters

Change one variable at a time, then retest. Monitor menus, cables, adapters and graphics drivers can all affect display-control behavior.

Many USB, Thunderbolt, or DisplayPort docking setups can block DDC/CI traffic between Windows and a monitor. This procedure is relevant to twinkle tray docking station on Windows 10 or Windows 11. Avoid assuming that settings on one display will apply identically to another model.

How to verify the result

Retest the exact scenario that failed originally, then document the cable, monitor model and software version if the problem continues.

Limitations: A working video signal does not prove the dock passes DDC/CI requests.
