# Some settings may impact device functionality. See link above for details# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=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 (this will force VGA)
#hdmi_group=1
#hdmi_mode=1# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4# uncomment for composite PAL

バージョンによって、設定コマンドが違うようです。
ググッた情報を自分の環境に合わせて変更してテストしないとうまく動作しません。
