Hi 袁 野
what bsp used in the case, one can try nxp official L4.1.15 from
this configuration works fine as described in attached Linux Guide p.26 using
boot command line:
U-Boot > setenv displayinfo 'video=mxcfb1:dev=ldb video=mxcfb0:dev=hdmi,
1920x1080M@60,if=RGB24' for LVDS and HDMI dual displays
Best regards
igor
