# Video mode settings

#
# Video mode settings can be custom or derived from a set of user specified
# parameters. To use a custom mode use the CUSTOMMODE variable, if empty the
# other parameters are used to derive the mode. In all cases the aspect ratio
# is always user specified.
#

#
# Custom video mode
#

# A custom video mode to use. The value of CUSTOMMODE should be the exact
# video mode specification to be passed to the kernel but without the
# aspect ratio. If not set (or empty) the other parameters are used.
# Examples:
# CUSTOMMODE="1024x640@60p-16:10 = 1024 640 60 152 48 19 1 104 3 -+ p"
# CUSTOMMODE="1366 768 60 cvt-R p"
#
#CUSTOMMODE=""

#
# Video mode parameters
#

# The mode to choose: VGA, ED, HD to choose resolution range automatically
# or an explicit resolution of the form WxH (e.g., 640x480).
RESOLUTION=VGA

# Force the vertical frequency, 50 or 60, instead of using first matching one.
# Use only if setting RESOLUTION to a particular resolution, not a range.
# Note that not all resolutions support all frequencies, so be careful to
# select a frequency which is valid for the resolution.
FORCE_VFREQ=60

# The scan type: 'progressive', 'interlaced' and any other value
# (including empty) for both (only the first letter is matched);
# if not set it defaults to progressive for backwards compatibility
SCAN_TYPE=progressive

# Whether the fixed mode database should be used. If 'yes' it is used
# instead of the display modedb and detection of display aspect ratio is
# disabled.
USE_FIXED_MODEDB=yes

# The types of modes to which the search in the fixed mode db should
# be restricted to. Known mode types are hdmi, vesa, gtf. Multiple
# types can be specified as a comma separated list (matches any). If
# not set any mode matches.
FIXED_MODE_TYPES=vesa

#
# Other non-video mode parameters
#

# Uncomment to force the aspect ratio of the video mode instead of using
# the one from the display. Value can be 4:3, 16:10 or 16:9
#FORCE_AR=

# The default monitor aspect ratio if none is detected or detection is disabled
DEFAULT_MON_AR=16:9

# Some HDMI displays advertise support for underscan but do not obey it,
# so it is disabled by default. If you know your display does properly support
# underscanned content then set HDMI_UNDERSCAN_IGNORE to "no".
# Modern displays do underscan, so force default to "no"
HDMI_UNDERSCAN_IGNORE=no

# Some HDMI displays do not advertise themselves as HDMI in the EDID (i.e. they
# do not include the HDMI identifier) or they are connected via an extender
# that does not correctly replicate the EDID. In these cases the driver will
# normally treat them as pure DVI displays and do not output any HDMI specific
# data (e.g., audio, info packets). This display type auto-detection
# can be overriden via HDMI_LINK_FORCE_TYPE, which can be set to NONE, HDMI or
# DVI. Setting it to HDMI forcefully enables HDMI mode with all HDMI specific
# data packets. Conversely setting it to DVI forcefully disables HDMI mode and
# no data is sent other than the video data (i.e. no audio and no ancillary
# data). Setting it to NONE (default) auto-detects the connected display type.
# NONE is the default even if HDMI_LINK_FORCE_TYPE is not defined
HDMI_LINK_FORCE_TYPE=NONE

# The VGA output has better quality when there is a non-zero DC voltage
# offset on the output instead of a more VESA compliant zero DC offset.
# Having a non-zero DC offset works with most displays as their input is
# AC coupled, but if that is not the case it can be disabled by setting
# VGA_DC_OFFSET to no.
# Defaults to yes if not set.
VGA_DC_OFFSET=yes

# To change the default power mode of the VGA and HDMI outputs set the
# POWER_MODE_VGA or POWER_MODE_HDMI variables to either "auto", "on" or "off".
# In "auto" mode the output is powered off when no connected display
# is detected (or detection is not supported by the hardware); in "on" / "off"
# mode the output is powered on / off, respectively, regardless of the
# detection of a connected monitor.
#
# Note that support for this feature is dependent on kernel driver version and
# hardware capabilities of the output device (e.g., some output devices may
# not be forced on, the driver may not support power modes, etc.).
#
# If not set then auto is assumed.
#
POWER_MODE_VGA=auto
#POWER_MODE_HDMI=auto
