How do I go Borderless Fullscreen?

Video Player: MPC BE
OS: Windows 10
Graphics: Integrated AMD Vega 8

So I want to watch a movie on my TV while duplicating the screen on my laptop. Every time I go fullscreen the player will automatically do something, like switch the main display to the TV, making the colors and screen refresh rate weird (Screen tearing etc..)

I noticed that this can be avoided when using Netflix or web browser video players like youtube etc... I assume that they play the videos in borderless mode.

How can I do that in MPC. I tried everything.

Thanks! Any help is appreciated
