Hi,

I am trying to play 4k video on a 4k display using imx8m evk on kernel release 4.14.78ga. on checking the FB mode using fbset command,

mode "3840x2160"

   geometry 3840 2160 3840 2160 32

   timings 0 0 0 0 0 0 0

   accel true

   rgba 8/16,8/8,8/0,0/0

endmode

But when I play a video it plays fine on terminal without error, but can't see any frame on display. On booting I can't see a desktop screen too. Is there something I am missing. As according to release note, 4k should be working on primary HDMI. On loading dual display dtb again 4k display won't show any thing on screen. Please help me with this.
