[Solved] How did I fix Screen Resolution in Ubuntu

Today, I’ve got a new external LCD Monitor on my work station. I had resolution issue in my Ubuntu 13.10. The monitor suggested the recommended resolution to be 1680×1050, but mine listed 1024×768 as it’s maximum resolution.

By Googling, I came across this post and it worked out for me:

Open up a shell :

$ xrandr

(This will show you your connection type, in my case it’s VGA1)

$ cvt 1680 1050 60

(Just type this in and hit enter, my refresh rate is 60. My resolution can handle 1680×1050. Copy the part after ‘Modeline’ e.g. Modeline “1680x1050_60.00” 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync then add this to the following command.

$ xrandr --newmode "1680x1050" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

(Notice how I took out the “_60.00” part after “1680×1050” above? It only works if you take out that refresh bit.)

$ xrandr --addmode VGA1 1680x1050

(This should add the new resolution you used to get, my monitor only gets to 1680×1050. The VGA1 is the connection type you get in the first command i mentioned. You might have something like hdmi1 or something.)
