# New Raspberry Pi OS images from Bullseye onwards come with this setting by default.

# (e.g. for USB device mode) or if USB support is not required.

# CPU/GPU core upper voltage limit. The value should be in the range [-16,8] which equates to
# the range [0.95V,1.55V] ([0.8,1.4V] on Raspberry Pi 1) with 0.025V steps. In other words,
# specifying -16 will give 0.95V (0.8V on Raspberry Pi 1) as the maximum CPU/GPU core voltage,
# and specifying 8 will allow up to 1.55V (1.4V on Raspberry Pi 1). For defaults see table below.
# Values above 6 are only allowed when force_turbo=1 is specified: this sets the warranty bit if over_voltage_* > 0 is also set.
over_voltage=6

# Frequency of the ARM CPU in MHz.

# https://www.raspberrypi.com/documentation/computers/config_txt.html#gpu_mem
# Specifies how much memory, in megabytes, to reserve for the exclusive use of the GPU:
# the remaining memory is allocated to the ARM CPU for use by the OS. For Raspberry Pis with less than 1GB of memory,
# the default is 64; for Raspberry Pis with 1GB or more of memory the default is 76.
# Unlike GPUs found on x86 machines, where increasing memory can improve 3D performance,
# the architecture of the VideoCore means there is no performance advantage from specifying values
# larger than is necessary, and in fact it can harm performance.

# https://www.raspberrypi.com/documentation/computers/config_txt.html#max_framebuffers
# This configuration entry sets the maximum number of firmware framebuffers that can be created.
# Valid options are 0, 1, and 2. By default on devices before the Raspberry Pi 4 this is set to 1,
# so will need to be increased to 2 when using more than one display, for example HDMI and a DSI or DPI display.
# The Raspberry Pi 4 configuration sets this to 2 by default as it has two HDMI ports.
# Generally in most cases it is safe to set this to 2, as framebuffers will only be created when an attached device is actually detected.
# Setting this value to 0 can be used to reduce memory requirements when used in headless mode as it will prevent any framebuffers from being allocated.
max_framebuffers=6

# https://www.raspberrypi.com/documentation/computers/config_txt.html#hdmi_drive
# The hdmi_drive command allows you to choose between HDMI and DVI output modes.
# 1 Normal DVI mode (no sound)
# 2 Normal HDMI mode (sound will be sent if supported and enabled)
hdmi_drive=2

# The hdmi_group command defines the HDMI output group to be either CEA (Consumer Electronics Association,
# the standard typically used by TVs) or DMT (Display Monitor Timings, the standard typically used by monitors).
# This setting should be used in conjunction with hdmi_mode.
