Tool/software:

from the output, it is 30fps for 4K resolution, how to set to 60fps?

Hi Tony,

This is a DP connection, so resolution is auto-negotiated through EDID from the display.

4K @ 30FPS is most likely a hardware limitation of the display, and the SoC itself has a limitation due to hardware DDR bandwidth.

Hi Takuma,

Confirmed by connect the display to Window PC, it is detected as 4K60fps.

Won't use AI feature on this application, major for display with GPU, can 4K60fps be supported to remove the limitation on SOC?

Hi Tony,

Unfortunately, no. 4K at 30FPS is current practical max.

However, as the SDK documentation mentions, this results in visual artifacts due to Video Sync Loss.

Takuma
