Lumia 950XL - Project My Screen not working after Win10 1803 Update - Black Screen

Anonymous

I use my 950XL extensively for demos of my company's software because it's much better display than my iPhone and doesn't need additional apps to do it.

I updated my Win10 desktop today to 1803 and also my phone updated to .104 and the app no longer works.

When I open the app I get the message on the phone to ask if I want to share and I agree. The display on the desktop is black, but I can actually start applications on the phone by clicking inside the black window, so there obviously is a connection, just no display.

I was working perfectly, but not now.

As a workaround, is it possible to use continuum? I'm sure there used to be an option to display the phone's screen rather than a full desktop to the connected display but that appears to be no longer available

Thanks,

Chris

    Not an Insider?  If you can reproduce the problem on a preview version you could add your feedback with the Insider feedback tool.  Otherwise, I'm not sure what kind of traction you would get from a report on the production feedback side.  Press Win+F and find out.

    Here's one (top hit) which claims the problem started with 16299.  This thread is indicating the problem started with 17134.

    No, sorry, I'm not an insider.

    Did you try  Win+F?   

    FWIW here is the closest hit that I could find on the production feedback app.   You can do better I'm sure.

    https://aka.ms/AA1fof7

    (in Apps  All Other Apps  search for

        1803  ProjectMyScreen.exe

    )

    The search in that tool is pathetic.  So who knows if anyone has actually reported this or not--undoubtedly not like this.

    There are no diagnostics.

    Maybe there are.  PmS was originally a Developer tool, so maybe in order to use it still you need to indicate that you are a Developer and opting for diagnostics and features available that way.

    Serendipity found this

    https://docs.microsoft.com/en-us/windows/uwp/get-started/enable-your-device-for-development

    So, see if it helps to turn on these two Developer options  (under Enable Device Portal and Device Discovery)

    • Turn on remote diagnostics over local area network connect
    • Make your device visible to USB connections and your local area network

    I may try these to see if they at least make any difference in a ProcMon trace.

    Good luck

    Ok, yes , the search tool is pathetic. I get some 50 hits, but none on PmS. But read what the first line says...
