Scope
This issue affects the following display models when using DisplayPort over USB‑C:
- MDRC‑8132 MKII
- MDNC‑8132 MKII
Symptom
When connecting the display to a workstation or laptop using the supplied USB‑C cable, the screen remains black and no image is shown.
In some cases, the display goes into standby mode after a few seconds.
Root cause
Out of the box, the product is configured to use DisplayPort IN 1 (Preset 1).
If the display is connected via any other input (including USB‑C/DP Alt Mode), it will not automatically switch to the active source.
Solution
Manually select the correct input preset via the On‑Screen Display (OSD) menu.
