Lenovo Y530 BLACK SCREEN when i fullscreen a game and the dedicated card takes over

[AntonisSip]

as title says when i start a game and goes to full screen and the dedicated takes over the intergrated gpu i get black screen and it never changes. i have to alt tab to the intergrated to close the game from task manager. But when i hook up the laptop to an external display it is connected via the gtx 1050 and it works flawlessly there. i have also updated windows/bios/gpu drivers (both) and from nvidia control panel and windows i have checked the games to run with the nvidia gtx 1050... any opinions on a solution about this problem?
