From here:
Setting
disable_overscan=1
in /boot/config.txt
might solve video problems for certain setups (removes black bars around the edges). If you have installed from NOOBS, there might be 4 other lines relating to overscan directions in the config.txt, such as overscan_left
, overscan_top
, etc. You should deactivate these lines by placing a #
as the first character on these lines. Note that for NOOBS installations, there might be duplicates of these lines at the bottom of the file.
Also, setting
hdmi_drive=2
seems to solve issues related to HDMI in some cases.
Can't change Resolution
If you have had to use
hdmi_safe=1
to make your pi display on your display, you will only be able to get 640x480 resolution. To fix this you need to use these settings to allow different resolutions.
hdmi_force_hotplug=1
hdmi_drive=2
and then set
hdmi_group=1
hdmi_mode=16
to force a resolution (those settings are for 1080p 60hz). More options can be found at: http://elinux.org/RPiconfig#Video_mode_options
