  3. Some settings may impact device functionality. See link above for details
  1. uncomment if you get no picture on HDMI for a default "safe" mode
  2. hdmi_safe=1
  1. uncomment this if your display has a black border of unused pixels visible
  2. and your display can output without overscan

disable_overscan=1

  1. uncomment the following to adjust overscan. Use positive numbers if console
  2. goes off screen, and negative if there is too much border
  3. overscan_left=16
  4. overscan_right=16
  5. overscan_top=16
  6. overscan_bottom=16
  1. uncomment to force a console size. By default it will be display's size minus
  2. overscan.
  3. framebuffer_width=1280
  4. framebuffer_height=720
  1. uncomment if hdmi display is not detected and composite is being output
  2. hdmi_force_hotplug=1
  1. uncomment to force a specific HDMI mode (this will force VGA)
  2. hdmi_group=1
  3. hdmi_mode=1
  1. uncomment to force a HDMI mode rather than DVI. This can make audio work in

  3. hdmi_drive=2
  1. uncomment to increase signal to HDMI, if you have interference, blanking, or
  2. no display
  3. config_hdmi_boost=4
  1. uncomment for composite PAL
  2. sdtv_mode=2
  1. uncomment to overclock the arm. 700 MHz is the default.
  2. arm_freq=800
  1. Uncomment some or all of these to enable the optional hardware interfaces
  2. dtparam=i2c_arm=on
  3. dtparam=i2s=on
  4. dtparam=spi=on
  1. Uncomment this to enable infrared communication.
  2. dtoverlay=gpio-ir,gpio_pin=17
  3. dtoverlay=gpio-ir-tx,gpio_pin=18
  1. Additional overlays and parameters are documented /boot/overlays/README
  1. Enable audio (loads snd_bcm2835)

dtparam=audio=on

[pi4]

  1. Enable DRM VC4 V3D driver on top of the dispmanx display stack

dtoverlay=vc4-fkms-v3d max_framebuffers=2

[all]

  1. dtoverlay=vc4-fkms-v3d
  1. NOOBS Auto-generated Settings:
