Hi, I’m facing an issue with my set up, I have an homemade bartop with a AMD ryzen 3400g proc (with radeon vega 11 graphics), a BENQ 21" screen as main monitor and a video projector as a second monitor. I can’t have display on the video projector, screen is black. The weird part is if I use “ALT+TAB” to switch app, I see the game running behind! And if I get focus back on retroarch, the screen is black again. Display on my benq monitor is fine. It happens with many core. I dont have issue with opengl driver, only vulkan.
I’ve tried to switch main monitro in windows option, same.
Thanks for your help
