I have this same problem as well, it would be great if you could help us to find a workaround. Thank you very much.

Does your computer (or laptop) have both integrated and dedicated GPUs? If so, then maybe it's related to the following issue: Error generated when Desktop Duplication API-capable application is run against discrete GPU.

Basically, the Desktop Duplication API doesn't support being run against the dedicated GPU in this case. Thus, the function DuplicateOutput fails and returns the error DXGI_ERROR_UNSUPPORTED (as we can see in the log you posted).

This was exactly my case and all I had to do was to force the python application to use the integrated GPU.

I'd suggest @nbrochu to document this since it's a quite shady issue and makes d3dshot unusable!

@Gabriel-Dev Thanks for making me aware of the use case of using it on laptops with hybrid GPUs (where I assume rendering gets switched from one to the other for power management purposes). I personally couldn't have anticipated this problem as I don't have a Windows laptop but it's very clear from what you linked that it runs into an issue on hybrid GPU systems.

To clarify for anyone else reading, it only causes an issue on laptops. I have multiple displays attached on my desktop, some on my discrete GPU, others on my integrated graphics and D3DShot works fine capturing any of them.

I'm really curious about the output of d.displays on laptop like these. If someone could help me out with that one that would be great.

I'd love to add a note to the documentation but I need to know what I'm dealing with first. Is the issue resolved by doing something in D3DShot (e.g. Picking a display set on the integrated graphics) or do you have do something outside to force Python to use that display adapter?

Also, not sure that this is necessarily the issue @hujiangchuan encountered but it could be. DXGI_ERROR_UNSUPPORTED can be raised in a lot of other cases like Windows<->Python bitness mismatch for example.

Someone getting this error in the dual-gpu laptop scenario reached out to me and we managed to get D3DShot fully working. There is no code fix required. As mentioned by @Gabriel-Dev, you need to make sure your python.exe and related processes you use (ipython, jupyter etc.) are set to be rendered exclusively on the integrated GPU. I will write a little guide for the wiki tomorrow and link to it from the readme in a warning to laptop users.
