I want to work in dual screen mode with the monitors not mirroring, but extending each other and I want the total resolution to be 3360x1050. When I try to apply dual screen (that is uncheck "Same image in all monitors" option) it says "required virtual size 3360x1050 does not fit available size 1680x1680".
Additionally, When I try to detect my monitors both are pink monitors, that is the monitors seem to not be detected as separate monitors
So the question seems to be two-fold: How do I detect the monitors as separate monitors? and How do I increase the available size?
