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

    I also have recompile the project with VS2017 but target 16299 and it's still funny display with my MADOSMA Q501(720x1280).

    I change the following line in WinPhoneProjection-master\src\WP81ProjectionClient\WP81ProjectionClient.cpp and recomple and it works!

    line 127: 

    MFCopyImage(pBuffer,dwStride,p,dwStride,dwStride,pData->wDisplayHeight);

    ->

    MFCopyImage(pBuffer,dwStride,p,pData->dwUnk3,dwStride,pData->wDisplayHeight);

    But are still no remote inputs from the software possible

    and are still reboot often. useless...

    Hey, it's not useless to me - all I want is to display the screen not to control it!

    Is there any way you could add your mods to the git project (or create a new one) with EXE so that others could test it with different phones?

    Unfortunately I don't have a suitable dev environment to try it myself.

    Thanks!

    Thanks for your interesting:)

    But most problem is reboot phone often(almost 100%) when

    App close/exit. It's painfull...

    I want to research about WinUSB bulk transfer.

    Would you give me a some time?

    Then, I upload it to my OneDrive Public Folder and share with you:)

    Please wait for a while:)

    Regards.

    Ok I'll wait - thanks for your efforts.

    To be honest, the reboot on disconnect isn't much of a problem for me either. I use my old 950XL to demonstrate my company's software mobile support. Most of the demo is using a web interface on the laptop but for part I show logging in on the mobile and doing some tasks. If it crashes afterwards on disconnect it doesn't bother me much.

    Hummm... I gave up;(

    I reduced the frequency of reboot phone

    but was not able to stop it.

    It maybe WinUSB Driver's bug or specification has changed...

    We must unplug cable before exiting the App.

    otherwise your phone reboot about 33%.

    Now , let you to share it!:)
