I have an i.MX 8MQ EVK and now evaluating.

I'm trying to output 4K video via HDMI port, but it does not work.

I was download 'L4.9.88_2.0.0_mfg-tool_MX8MQ.tar.gz' from NXP website and make a SD card for boot that using a script 'mfgtool2-yocto-mx8-evk-sd2.vbs' with Mfgtool2.


After making, boot from SD card.
Default is displaied by 1080p60 from HDMI port and it works.


I refered some post and changed bootargs setting to 4K output, but not works.

Is it correct procedure?
Or the OS does not support 4K yet?
I'll attached boot log.
