# This specific configuration was made for use in the CrowPi L
# laptop enclosure for Raspberry Pi 4 with a focus of maximizing battery
# life. The processor is clocked down to 700 Mhz (same as the original
# Raspberry Pi), LEDs on the mainboard are disabled, and the screen
# size is adjusted to conform to the CrowPi L's 1366x768 panel.

# For more options and information see
# http://rpf.io/configtxt
# 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_force_hotplug=1

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