Thank you @tooz I tried some solution. a1) The resolution is 1920x1080 of the 1st pic. a2) I could not modify the resolution to 1024x768. settings-> display-> HDMI-> resolution-> [1024x768 ] was can not found. I am not try to flash the board to android 11 yet. a3) monitor is connected to the HDMI port. That commands in adb shell was not work. "su" command was want a password , and I don't know correct password. "setprop" command was "not found"
