ROC RK3328/RK3399 No Video on Monitor

Please use this thread to report no video issues on boards with the ROC- model prefix.

  • ROC-RK3328-CC Renegade
  • ROC-RK3399-PC Renegade Elite

This device was designed for most standard resolution HDTVs and monitors. HDMI supports two modes:

  • CEA Consumer Electronics Association
  • DMI Digital Media Interface

Different video modes require proper clock generator and setup to create the appropriate synchronization frequencies with the display. This is a very complex topic beyond the scope of this post.

If you have a monitor that is not showing video, please post on this thread with the following information if possible:

  1. Monitor/TV Make and Model
  2. Native Resolution
  3. EDID Dump

It is not guaranteed that every monitor resolution is supported due to the limitations on the onboard clock generator. By reporting the issue, we can identify target clocks and resolutions to debug over time.
