Is there still no update from Dell on this issue? I have a Dell Precision 5540 with a Quadro T2000 that I use for CAD design and rendering. It seems completely random when it will actually use the Quadro and when it will just try in vain to render complex 3D assemblies with the integrated UHD graphics. I've done all of the recommended fixes, changing settings in Nvidia Control Panel to use the Quadro for all applications, and right clicking specific applications and choosing "run with graphics processor" and choosing the Quadro. None of it seems to have any effect at all. The computer just uses the UHD graphics 90% of the time.
I've even tried completely disabling the UHD graphics in Device Manager, and this works but of course I can't have any external displays while in this state because the Quadro doesn't actually have access to the video ports.
Dell, please just make a setting somewhere in Windows or BIOS that will allow users to actually make the computer use the dedicated graphics card we paid so much money for.
