Photoshop: GPU not actually working (multiple card issue)

I'm not 100% this is the right place for bug reports so please tell me if I should post this somewhere else instead, thanks.

Photoshop detects my GPU correctly but only uses it if i create a file on the screen plugged to the graphics card.
So for example if I create or open a file on screen 1 and move it to screen 2, screen 2 will be using GPU even though it's plugged to the motherboard. However if I open a file with Photoshop being in screen 2, it'll be using CPU no matter where we move photoshop.
So some tabs/files will work on GPU and others on CPU, even though GPU usage is checked!

If this is unclear I tried to make a quick video to detail this here :  https://youtu.be/Wo-pQ9NaIag
It might be a little subtle, so maybe turn on 1080p to see how pixelated the line actually is.
Also I'm on windows 8.1.

Photoshop only uses your primary card for GPU acceleration.

Thanks for your answer, my problem actually got solved by plugging my tablet on my graphic (which for some reason used to be impossible)
I don't think Photoshop should leave you the option to use GPU when you actually can't though.
