# Custom modeline!
# To use custom modeline you need to disable the above resolution
# and setup your own! 
# For more information check our wiki: 
# http://odroid.com/dokuwiki/doku.php?id=en:c2_hdmi_autosetting
# Example:
#setenv m "custombuilt" 
#setenv modeline "1920,1200,154000,74040,60,1920,1968,2000,2080,1200,1202,1208,1235,1,0,1"

# HDMI BPP mode
setenv m_bpp "32"

# HDMI DVI/VGA mode: "dvi" or "vga"
#setenv vout "dvi"

# HDMI HotPlug Detection control: "false" or "true"
# Allows you to force HDMI thinking that the cable is connected.
# true = HDMI will believe that cable is always connected
# false = will let board/monitor negotiate the connection status
setenv hpd "true"

# Toggle HDMI output: "false" or "true"
setenv monitor_onoff "false"

# Toggle CEC support
# 0 = Disable CEC
# 1 = Enable CEC
# 2 = Enable but disable auto TV switching ON
setenv cec "1"

# Force HDMI to use RGB colorspace regardless of TV request
# 0 = Disable
# 1 = Enable
setenv hdmi_forcergb "0"

# Default console settings
setenv condev "consoleblank=0 console=tty0 console=ttyS0,115200n8"

# Meson Timer
# 1 = Meson Timer: improves the video playback but breaks KVM/virtualization
# 0 = Arch Timer: allows KVM/virtualization to work but you'll experience poor video
setenv mesontimer "1"

# Disable video output
# - Setting nographics to "1" will disable all video subsystems.
# - This mode is ideal for headless server type usage, as it saves ~300 MiB RAM.
#setenv nographics "1"

# Toggle UHS (Ultra High Speed) micro SD mode: "false" or "true"
setenv disableuhs "false"

# Force micro SD detection: "false" or "true"
# - Forces the MMC controlled to believe that a card is connected.
setenv mmc_removable "true"

# Toggle USB multi-webcam tweak: "false" or "true"
# - Only enable this if you use it.
