Hi
I'm trying to change my kiosk's HDMI output settings. Its currently defaulting to the wrong resoltuion (due to a port HDMI port switcher we are using).
How do we set it to one resolution?
I found this documentation, but it hasnt been much help.

Thank you.

Hello 2012firstuser,
As explained in documentation you need to:
a) boot any linux (or login to kiosk through ssh) on a target PC
b) run 'xranrd' command and gather data
c) modify your 'screen_settings=' parameter
Sample 'xrandr' output on my PC looks as follows:
Code: Select all
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DVI-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 528mm x 297mm
1920x1080 60.00*+
1680x1050 59.88
1600x900 59.98
1280x1024 60.02
1280x800 59.91
1280x720 59.97
1024x768 60.00
800x600 60.32
640x480 60.00
720x400 70.08
DIN disconnected (normal left inverted right x axis y axis)
DVI-1 disconnected (normal left inverted right x axis y axis)
Basing on this data you can construct following parameter:
Code: Select all
screen_settings=DVI-0:720x400:70.08:normal:normal:normal
to set higher resolution and rotate on the left:
Code: Select all
screen_settings=DVI-0:1680x1050:59.88:normal:left:normal
Thank you.
