# uncomment if you get no picture on HDMI for a default "safe" mode # hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan # disable_overscan=1 # uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border # overscan_left=16 # overscan_right=16 # overscan_top=16 # overscan_bottom=16 # uncomment to force a console size. By default it will be display's size minus # overscan. # framebuffer_width=1280 # framebuffer_height=720 # uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode (here we are forcing 800x480!) hdmi_group=2 hdmi_mode=87 hdmi_cvt=800 480 60 6 0 0 0 max_usb_current=1 # uncomment to force a HDMI mode rather than DVI. This can make audio work in # DMT (computer monitor) modes # hdmi_drive=2 hdmi_drive=1 # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display # config_hdmi_boost=4 # uncomment for composite PAL # sdtv_mode=2 # uncomment to overclock the arm. 700 MHz is the default. # arm_freq=800 # for more options see http://elinux.org/RPi_config.txt
