Our new 16/9 video beamer has some 16/9 issues as we only use a VGA (loooong) cable. So thet 16/9 laptop connected to the 16/9 projector switches to 4/3 as there seems to be no DCC signal coming through. That result in a nice 4/3 image on the 16/9 projector... pfuuuh
So here comes the xrandr,as seen on 29C3 Note that not all this will work on your laptop (e.g. the name of the display)
# my laptop is 1366x768, so that what I use #gtf 1366 768 60 # this gives the parameters for the next line xrandr --newmode "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync xrandr --addmode VGA1 1368x768_60.00 xrandr --output VGA1 1368x768_60.00 xrandr --output VGA1 --mode 1368x768_60.00 # mirror mode xrandr --output VGA1 --mode 1368x768_60.00 --same-as LVDS1 xrandr --output LVDS1 --mode 1366x768
