I am using a secondary monitor with a laptop. The laptop is 1920x1200 and the 1280 x1024. The issue is that the laptop monitor is fairly small while the secondary monitor is relative large. I find the laptop not comfortable to read at at 3.5' ~ 4' away but if I change the default DPI for the system it makes things in the second monitor look huge. Is there a setting or an app that can set a DPI for one screen while keeping the other the same?
Consider using the Windows 7 Magnifier tool...
There are options to magnify
