Hi XavierSu,

According to your post in another thread, what you are doing is dsi-> dsi2hdmi->hdmi.
You have to make sure the display timing/mode you write into the dts file matches the criteria of our display driver.

Please refer to
kernel/nvidia/drivers/video/tegra/dc/mode.c -> check_t21x_mode_timings
