Multiple monitor DPI Issues (Desktop not Metro)

Hi,

I have a Lenovo Yoga 2 pro with Win 8.1, which has an ultra high resolution (3,200X1,800) and I am using it with a Targus docking station.  In order to see things, I have the custom DPI scaling set at 250%.  Here is the problem, when i use the docking station with an external monitor that has a maximum of 1900X1200, Metro looks nice, but anything on the desktop (office and other desktop only programs), everything is HUGE and unusable.  If I try to set DPI scaling for multiple monitors, I can no longer use my custom 250% DPI for the Lenovo, instead, I am given a slider that makes the external monitor look nice, but when the laptop is removed, it is so small that I'd need a magnifying glass to see.  If I want to use a docking station, I have to change the DPI scaling every time I switch between being docked and as a standalone, which requires me to go through all of the steps to switch and then log out and log back in.  Is there a way to have custom DPIs for each monitor?  I think this will only become a bigger problem as more companies develop higher resolution devices.

Thanks,
Dean
