If you have connected your Raspberry Pi to an HDMI enabled TV or a monitor, sometimes you may encounter continuous black border across the screen on all four sides or two. This border running across the screen may be seen on both GUI mode or command line interface mode on your Raspberry Pi screen.
If you are facing a similar issue on your Raspberry Pi and looking for a way to get rid of this black border across your Raspberry Pi HDMI Monitor/TV screen, then follow the following procedure to get rid of them.
/boot/config.txt
In this file, you will encounter the following lines:
overscan_left=-16
overscan_right=-16
overscan_top=-32
overscan_bottom=-32
It is these configuration lines that are responsible for setting the screen size and overscan capabilities of your HDMI display screen.
Altering these values should start showing an effect on your Raspberry Pi HDMI screen display. Modify it sufficiently until you are able to get rid of the black border across your Raspberry Pi screen.
Note: If you are not seeing any variation in the displayed screen even after modifying the above values on your config.txt file, then may be you will have to ensure that the value:
disable_overscan = 1
is not set anywhere in Raspberry Pi bootable environment. Hope this helps!
