Monitor black screen flashes predator xb273k

Terrallel

Hello everyone I’m having trouble with my Acer predator xb273k. I’ve been using two dp1.4 cables to get 144hz but I recently got the Alienware 360hz monitor so I took out one of the dp cables and am using it for the other monitor. Since I’ve been using one dp for the Acer monitor it has been getting black screen flashes for about half a second every so often. It’s more frequent the more active I am on the monitor and am not sure how to fix this. The black screen flashes happen when I use the Acer monitor with one dp regardless how many other monitors are connected

Does the same issue occur when changing the resolution and refresh rate?
