Hello.
As you’ve surely noticed, when connecting the Raspberry to a FullHD monitor, the resolution isn’t 1920x1080, and it’s not possible to select it.
To force this resolution, go to:
sudo nano /boot/config.txt
look for all
disable_overscan=0
and change the value to 1 (from 0 to 1).
Finally, at the end of the file, comment out the following lines (comment with #):
overscan_left=24 overscan_right=24 overscan_top=16 overscan_bottom=16
Restart the Raspberry.
Bye!
! :) !
