Question When i turn off the TV my monitor flickers and gives me a black screen ?

[Vetrix1996]

I use windows display switch to switch between my HDMI LG CX and my DisplayPort Monitor. When i turn off the TV my monitor flickers and gives me a black screen. Only way to fix is to unplug the DisplayPort cable from gpu and plug back in again. Any way around this?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

As for your GPU, what driver version are you working with?
