# h3disp
#
# Patches fex/script.bin settings to modify display settings. Currently
# rather limited and only supporting HDMI and the available presets.
#
#############################################################################
#
# Background informations:
#
# Only a certain amount of predefined video modes is available on H3 devices
# as can be seen here: http://linux-sunxi.org/Fex_Guide#disp_init_configuration
#
# Purpose of this script is to display the available reasonable settings and
# let the user choose from them to adjust fex file accordingly afterwards.
# In the meantime it's also possible to specify available resolutions on the
# command line. To display possible values use the -h switch.
#
# If HDMI-to-DVI adapters are used another fix has to be applied to the fex
# file: http://linux-sunxi.org/Orange_Pi_One#HDMI_to_DVI_converters -- so ask
# user whether he plans to use such an adapter and adjust fex file accordingly
#
#############################################################################
#
# CHANGES:
#
# v0.4: Added new modes in a combination with kernel patch, but they refuse to work.
# Additional work is needed for all modes larger than 10
#
# v0.3: Added the ability to set the colour-range HDMI-output and spruced the
# output of h3disp in general with a splash of colour. Also, don't spit
# out so much text by default.
#
# v0.2: Added non-interactive mode. You can provide one or two arguments on
# the command line, eg. 'h3disp -m 1080p60 -d' (1920x1080@60Hz DVI) or
# 'h3disp -m 720i' (1280x720@30Hz HDMI). Complete list of modes via
# 'h3disp -h'
#
# v0.1: Initial release to adjust display settings in script.bin on commonly
# used Debian based OS images for H3 devices running Linux.
#
#############################################################################
#
# TODO:
#
# - implement real user interaction: dialog that asks which of the available
# HDMI modes to choose and whether a HDMI-to-DVI converter is used or not
#
# - maybe implement live resolution switching as outlined by Jernej:
# http://forum.armbian.com/index.php/topic/617-wip-orange-pi-one-support-for-the-upcoming-orange-pi-one/?p=5305
# (we would also need a working set of fbset modes in /etc/fb.modes
# of course)
#
# - maybe add the chosen mode to /boot/boot.cmd and create /boot/boot.scr
# afterwards?
