Simply turn off the intel GPU in the BIOS. This has nothing to do with obscure conspiracy theories, it's simply how OpenGL works - it will always use the primary display client.
Thanks for your response. I did consider disabling the Intel GPU altogether but thought there was still some benefit for keeping it on for other functions and applications. If not, this will be my solution. Thanks
Looked at turning off Intel GPU as solution and while this does work, I don't think its a good long-term solution. This is because I have a Dell Precision M6800 which, from what I read on Dell's support forums, doesn't have a normal BIOS area. It runs everything off there loaded software and doesn't give me an option to disable the Intel GPU there. I can only disable it in the Device Manger, which works but causes other problems. The Dell support forums also indicated that even though I have a secondary Nvidia GPU, it'll still runs thru the Intel GPU as an adapter. This seems to be true because when I disable the Intel GPU in the Device Manager, the Nvidia Control Panel is no longer accessible and it gives me a popup stating something along those lines.
If any other solutions can be provided, I would much appreciate it. Ideally, I think it would be best if I could keep the Intel GPU running and just get AE to use my Nvidia GPU. Still don't know if this is an Nvidia or an Adobe AE issue. I guess it could also be a Windows 10 issue.
Found a way to fix the problem. In the Nvidia Control Panel, setting After Effects to use High-performance Nvidia processor was changing to Integrated Graphics after saving and closing panel. So I tried setting After Effects to Integrated Graphics and after saving and closing the panel, it changed to the High-performance Nvidia processor. Not sure why, but After Effects is now using Nvidia as Open GL and can run Element 3D without errors.
