I have a dual monitor setup using the ViewSonic below as my primary and the Acer as my secondary. I'm assuming that the Acer does not send the EDID so it's not picking up on the correct native resolution. The ViewSonic works right away when I installed the nVidia drivers. That has a native resolution of 1440x900 and so does the Acer so I know the hardware is capable of that resolution. I have searched and searched and have not been able to get it to work. I've tried adding modes through xrandr but I get an error when I try to add the new mode to the output the Acer is using. I've also attempted to add metamodes to the xorg.conf which for some reason don't show up in the nvidia-settings dialog.


  • nVidia 8800GTS (specifically this)
  • ViewSonic VA1930wm
  • Acer AL1916W

Doesn't look like anyone has an answer. I remember getting this working at one point (when I had Ubuntu installed alongside Win7) I just don't remember the specific configuration in the xorg.conf that made it work. –  justin.chmura Mar 19 '13 at 15:53
