#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.

#hdmi_force_hotplug=1
uncomment to force a specific HDMI mode (this will force VGA)
