I have an issue for a long time on my Acer Spin 5 SP515 laptop, with NVIDIA GeForce 1050 dedicated video card along with integrated Intel UHD 620 video card on Windows 7. I thought this comes from the Intel video driver, but I tested a lot and found out that when I disable the dedicated NVIDIA card problem goes away. I simply get black screen at various moments, I think when the dedicated video card needs to be used for extra acceleration.
I tried all the drivers I could find for the NVIDIA card, along with various driver (modified/patched) for the Intel video card. Does anyone have any ideas what could be the problem?
