When rebooted, confirm the video levels are correct by using the following command again:

tvservice –s

The output should now show “full”

“HDMI CEA (16) RGB full 16:9, 1920x1080 @ 60.00 Hz, progressive”

5.4 To disable overscan (if black bars are visible on the sides of the

screen)

Either

• Run the Raspberry Pi Config utility from the terminal

sudo raspi-config

Select: 9 Advanced Options

Select: A1 Overscan

Select: No

• Edit the config.txt file to disable overscan:

sudo nano /boot/config.txt

Look for the following section:

# uncomment this if your display has a black border of unused pixels

visible

# and your display can output without overscan

#disable_overscan=1

Edit the last line to remove the #.

disable_overscan=1

Save the file and reboot.

5.5 To rotate the screen image to portrait orientation

Use the Screen Configuration tool available on the OS Preferences menu. Select the screen and select

Orientation. Change the setting to “Left”. This will match the display being physically rotated

counterclockwise into portrait orientation.

Important: Using the display rotated clockwise is not approved due to the cooling design.
