Windows 10: intermittent black screen flashing with HDMI splitter

I’m running Windows 10 on my Mac Mini using Bootcamp.

I bought myself a HDMI splitter so that I could connect both my Mac and my PS3 to my Dell monitor.

The switcher works fine when I’m running MacOS… but when I switch to Windows I keep getting these occasional black screens flashing intermittently. I removed the HDMI splitter and the screen started working normally again.

Is there a way to fix this by changing some of the settings in Windows 10? Or might I need to try a different splitter or just use two different types of cables? (e.g. displayport for my Mac and HDMI for my playstation)
