Good day, the board does not work with a 7" LCD screen (1024x600). When turned on, the screen shows the inscription “Not supported”, then blinks several times and when the operating system is finally loaded, the screen starts in a resolution of 1920x1080 (upscale mode). In this case, you can change the resolution in Linux to 1024x600, but the monitor again complains about “Not supported”. I tried with different screens MPI7002 and MPI7006. Perhaps the problem is that it does not like the 1024x600@60.04hz mode. At the same time, these screens work fine with orangepi 3b
Can you tell me if you can find a similar display that connects via HDMI and not dsi like yours? Maybe you need to throw a modified edid into the kernel.
I think I can configure xfce for the desired resolution, but I want full, correct display operation (splash screen, boot sequence, etc.)
Here are some tips for Raspberry Pi, but I don’t think this recipe will work on this board, but maybe it will help to understand the direction of the problem

Thanks for the feedback. We see that most Raspberry Pi HDMI displays on the market have a resolution of 1024x600. We will try to test it.
I have already use 1024*600touchpad on 2b.To do that ,u can: cd /boot/start,then sudo nano screen.sh, paste the code:
export DISPLAY=:0
while true;do
if xdpyinfo > /dev/null;then
break
fi
sleep 1
done
xrandr --newmode “1024x600_60.00” 59.8 1024 1072 1168 1312 600 603 613 624 -hsync -vsync
xrandr --addmode HDMI-1 “1024x600_60.00”
xrandr --output HDMI-1 --mode “1024x600_60.00”
after that,have a reboot.
Yes, this is a working solution to make xfce start with the required resolution. But when you turn it on, the screen displays the message “Not supported” for a long time and only at the very end of loading the graphical shell does the screen turn on. In any case, thanks for the help. I want to make a commercial solution on this device, so I need all stages of the operating system loading to work (including the logo). Most likely, this will also require tricks with uboot or the kernel
