External display and laptop display turn black for a second
Every so few minutes or so, both the external display monitor and the XPS 13 9360 screen turn black for about a second and then back to normal. I've noticed that this only happens when WIFI is turned on. This only happens when the external display is connected. The external monitor is a LED samsung display connected via HDMI cable through a hdmi to Usb-C dongle. I've tried changing the refresh rate of both displays to 60 Hz - no change. All drivers are updated.

The following site may help. Also check your power management. Set for Maximum Performance instead of Balanced or Power Saving.
