One thing should be attention, In the BIOS piriod, The resolution of the DP Source is 1024*768, But when enter the Linux OS, the resolution of the DP Source change to 1920*1080. How can we fix the problem，make the LVDS Panel work well in the BIOS piriod? I have seen https://www.nxp.com/docs/en/application-note/AN11133.pdf and https://www.nxp.com/docs/en/application-note/AN11134.pdf?fsrch=1&sr=2&pageNum=2 on page 6 it shows how to read the hardware and firmware version.
