Hi, I have two monitors, one internal and one external, configuration goes as follows:


MacBook Pro (Retina, 15-inch, Mid 2012) Native display/monitor




Detected by Windows as: "Generic PnP Monitor"


LG D2343P External Monitor




Detected by Windows as: "LG 2343(Digital)"


I want to make both displays to work together with different "DPI Scaling" on Windows 8.1 Pro Preview so GUI elements render correctly scaled between them just at it happens on Apple OS X, I have read an excellent article which shows how to change and customize this settings but settings apply over all displays and there isn't a way to make windows know the DPI/PPI of the Retina monitor. ows-8-1-a.html



How can I achive this?

    Even after Windows 8.1 has been officially released I'm still unable to get multiple monitor scaling working.


    My setup is rMBP (2880x1800) and a Thunderbolt Display (2560x1440).  Ideally trying to get 200% scaling on the rMBP and 100% scaling on the Thunderbolt Display.


    Any help is appreciated.

    Hello. I have the same setup - Windows 8.1 on Macbook Pro Retina and Thunderbolt display.


    What I've noticed is that in the device manager both the Thunderbolt display and the Macbook screen show up as "Generic PnP Monitor," and I am wondering if these generic device drivers are not passing the correct resolution/screen size informations to the OS.


    Maybe Apple can create customized drivers for each one of their monitors instead of using the generic driver?
