Android Emulator no longer works Windows 10 Anniversary

[AlbanRampon]

I'm sorry but can you explain why you think an issue with HW acceleration and an Android emulator has something to do with DisplayLink?

DisplayLink is not a graphics card with hardware acceleration. Pixels are NOT computed by the physical adapter but by Windows through the graphics card...
I would need a bit more info to get going.

I know this is a few months later, but I can answer you, Alban. This happens both when launching Minecraft or the Android Emulator (both Java apps trying to take advantage of hardware acceleration)... they crash with a GL error when the DisplayLink device is connected and powering the monitors while the laptop screen is shut off.

If you unplug the DisplayLink device, turning on the laptop screen, they launch just fine on the laptop. You can then reconnect the DisplayLink Device, turning off the laptop screen and running either application on a DisplayLink-driven monitor in a multi-monitor context without issue.

They will also launch on the laptop screen when it and the other two monitors are active, and can then be dragged to one of them.

So this issue is with multiple apps from different makers and *directly* related to DisplayLink driven monitors.

I have downloaded the October 25th driver update (8.0M3), installed, and rebooted prior to confirming these issues remain in the latest version of the drivers.

I have a Core i7 6700-HQ, 16 GB of RAM with a 4 GB nVidia GeForce GTX 960m. If I try to launch the nVidia Control Panel I get an error that I am not using a display currently connected to the nVidia GPU.

Based on some conversations, it seems this may be rectified if we downgrade to an earlier GeForce driver, but I don't know which.

Hello,
I've had communication with Microsoft on the OpenGL thing since.
This is a primary graphics card driver issue. Microsoft gave them notice about what they would need to implement and I've been informed latest drivers should already support this. (DisplayLink does not compute pixels so the DisplayLink drivers have never done OpenGL... yet it worked before the anniversary update)
Could you please attach the output file (dxdiag.txt) of the following command so I can hand it over to Microsoft?
dxdiag /t dxdiag.txt

nVidia will have to implement the support for indirectly connected monitors in their utility, this is unfortunately not something we can do. This is a feature available in Windows 10 Anniversary Update onwards. As you are their customer, may I suggest you flag this to them?

Kind regards,
Alban
