Screen Flashes with Dual Monitor Setup on 2017 ...

I have two 27" Planar monitors connected with DisplayPort adapters. Whenever I plug in both monitors, trying several different adapters, the second monitor that I plug in sporadically flashes black for a couple seconds. I've tried resetting PRAM and SMC. Has anyone else encountered this issue?
