Span feature is only available when using multi-monitor configuration in extended desktop or collage mode.
Please try loading the latest video drivers for Windows® 10
Also, please connect both monitors using straight video cables (no adapters), this will limit multi monitor functionality.
If possible please attach screen shot of the graphics Multiple Display configuration from theIntel® graphics control panel.
I tried two of Intel's latest drivers.
Firstly, I tried the driver from the link in your email--win64_154001.exe.
Secondly, I tried the latest driver from 2016--win64_154025.4464.exe.
Both drivers installed without any issues.
Both drivers allowed me to enable both monitors in extended desktop mode.
However, I was not able to find the SPAN mode in the drivers.
The Operating System still sees two distinct monitors with both drivers; therefore, when I expand my UWP C++/CX application full screen it only expands to one monitor. I can stretch the application to span both monitors, but it will not expand to both monitors.
I would like the UWP C++/CX application to expand to both monitors as if they were one.
(The Universal Windows Platform does not give me control over this programmatically.)
If you are a software developer, I would recommend contacting our software department and try to get more information about UWP C++/CX application.
