Extended display, not mirrored for Windows 10 on a MacBook Pro?


I have a 2016 MacBook Pro 15.4" optioned to the hilt except with the 1 terabyte SSD, with the latest Sierra OS, and a Dell P2418HT external monitor with Touch-Base drivers to enable the touch screen. The MacBook Pro and external monitor are connected with a Cable Matters USB-C to DP cable, and a USB-C to USB 3 cable. I have Windows 10 Pro on Bootcamp and on a VMWare virtual machine. I use the virtual machine to run a Windows only CAD program IntelliCAD, and other Windows only programs such as Bluebeam VU.

I can do an extended screen on the Mac side with Mac programs with no problem, and thus have a separate image on each screen. But on the Windows side and the Windows programs I am unable to do an extended screen, only mirrored screens, which means I have the same image on both screens. I have loaded the drivers for the Dell monitor into Windows. I have tried to redo the Windows settings to enable extended desktops.

But I must be doing something wrong, because I am still unable to get the extended desktop to work on the Windows side. I am still stuck with both screens mirrored with the same image. If I select extended desktop, the Windows screen image is just a black screen with an intermittent flickering cursor, and every so often a very small image of the CAD screen will flash on and off for a split second.

I will I’ll surely appreciate any suggestions to help resolve this issue. Thank you so very much for any help you can give me!


Hi Ronald,
