Hello,
Board: i.MX 8QuadXPlus MEK Board
Version: android_O8.1.0_1.1.0_AUTO-EAR
Display:LVDS to HDMI with IT6263
How can I change the 1080p display to 720p display.
I noticed that there is a "video=HDMI-A-1:1920x1080-32@60" arg on i.MX8QuadMax MEK board.
but this arg does not work on i.MX 8QuadXPlus MEK Board.
please help me.
thanks a lot.
You can change this option in u-boot configuration accordingly to actual display resolution.
I mean you can enter u-boot command prompt then overwrite the option and then perform "saveenv" to save the configuration.
Have a great day,
Victor

Hi Victor,
Thanks for your reply.
But I am not sure about the ‘video=’ part in the u-boot cmdline.
If I set it "video=HDMI-A-1:1280x720-32@60",
cat /sys/class/graphics/fb0/modes
U:1280x720p-0
But the display resolution is still 1080p.
If I set it "video=mxcfb0:dev=ldb,1280x720-32@60" ,
the kernel log showed "drm_helper_probe_add_cmdline_mode cmdline_mode->specified ==0 ",the display resolution is still 1080p.
Can you give some details?
Thanks a lot.
Nice day.
XinChuan
