IMX8MQ (chip model: MIMX8MQ6DVAJZAB) dual screen display

[ximenbingmeng]

1.Does the IMX8MQ chip support dual screen display? What are the restrictions on using it?
2.If the IMX8MQ chip supports dual screen display, what are the resolutions and refresh rates supported by the HDMI interface and MIPI-DSI when used simultaneously?
3. The kernel version we are currently using is 4.14.98. Does this version of the software support dual screen display? How should the device tree be modified if it is supported? Is there a manual available? Are there any tested examples for our reference? Thank you very much
4. If you purchase an official development board, can you directly connect two HDMI interfaces to test dual screen display?
5. Is there a requirement for the size of DDR for dual screen display?
Looking forward to your reply, thank you very much!
