Title: USB Type C Display Issue [Print This Page] Author: YLCHEN Time: 6/3/2019 11:39 Title: USB Type C Display Issue Hi,
We tested ROC-RK3399-PC USB type C display performance and had two problems:
1. Connect to DP 4K Monitor with USB Type C to DP Dongle
-->Monitor works only on certain side of USB Type C connector.
2. Connect to USB Type C Monitor (Dell U3219Q)
-->No Function. Nothing displays on the monitor.
Does anyone have the similar issue and know how to fix it?
Thanks in advance!Author: penguin Time: 6/5/2019 14:16
Could you elaborate a bit about "on certain side of USB Type C connector"?Author: YLCHEN Time: 6/6/2019 11:44
Thanks for asking. As far as we know, USB-C plug may be inserted either side (the connector is reversible so that it can be used in any orientation). But in our test, when using USB-C to DP Dongle, the USB-C on the ROC-RK3399-PC only displayed (have function) in one side. If we turned to the other side and stick in the USB-C connector, the monitor showed nothing.
How about the second issue? (connecting to USB Type C Monitor) What's the potential cause?Author: YLCHEN Time: 6/17/2019 15:00
Any update on this?Author: penguin Time: 6/18/2019 16:59
1. Connect to DP 4K Monitor with USB Type C to DP Dongle
-->Monitor works only on certain side of USB Type C connector.
This has been confirmed. It's the driver problem.
2. Connect to USB Type C Monitor (Dell U3219Q)
-->No Function. Nothing displays on the monitor.
Copy the code
We haven't this monitor, so would you please attach a kernel log with monitor plug out and in. Author: raynort826 Time: 1/13/2026 12:09
