Hardware Acceleration disabled with connected DisplayLink

[Freebit]

Hello,

I use a Targus Universal USB 3.0 DV Docking Station together with a DELL Inspiron 7000 series laptop. The laptop has a Intel HD 5500 graphics card (intern) which uses an NVidia GeForce 845M GPU for hardware-accelerated applications.

When I open "chrome://gpu/" with the Chrome browser, the WebGL feature (and others) is "Hardware accelerated". When I connect the DisplayLink with the USB connector it'll be "Software only. Hardware acceleration disabled".

The DisplayLink drivers are all new and I tried to disable all GPU drivers and reinstall them afterwards. This did not help.

Is this docking station incapable of handling hardware-acceleration in connection with such laptop GPU cascades?

Thanks!

Hello Freebit,

Thanks for your patience whilst I was on holidays.

The error message is kind of misleading...
DisplayLink chip is NOT a GPU. The GPU does the hardware acceleration even for indirectly connected monitors because the GPU computes the pixels in all cases (through DisplayLink or directly connected to the graphics card).
So this is not the real problem, despite what is being reported!

I've been discussing this with Microsoft and they informed me they have sent the details to the graphics card vendors well before the Windows 10 Anniversary Update for them to release new drivers which will handle the new OS feature properly.

Would you please be able to post the dxdiag.txt result from the following command?
dxdiag /t dxdiag.txt

I will hand it over to Microsoft to get their advice on the graphics driver you are running.

Kind regards,
Alban
