My monitors are only 1920x1080: a 17” laptop and a 50” TV. The smaller laptop sits four feet away and I need to increase the size of everything to see it better.
Go into System Settings -> Screen Display
On the Scale for menus and title bar, I set to 1.5 on 17” Laptop screen but leave at 1.0 for TV. I’m not sure if this will work for you…
Edit 1 - Increase overall DPI scaling
The deafult DPI in X is 96 Dots per inch. This can appear very tiny on my 17” laptop screen with a resolution of 1920 x 1080. You need to stick your face 6 inches from the screen to read the screen for the Kids3 application for example:
To solve this (in my case), use:
xrandr --dpi 168
Then reopen the application:
This is a manual method. You can make it permament but you can have X calculate the DPI by passing it your resolution and screen size in the Xorg configuration file:
Section "Monitor"
Identifier "Monitor0"
DisplaySize 286 179 # In millimeters
EndSection
I haven’t played with this yet.
