XPS 15 9570 EXTERNAL DISPLAY FLICKER ISSUE

Hello there!

Running a 2018 XPS 15 9570 w/ NVIDIA GeForce GTX 1050i

Since I purchased this computer and got a USB external monitor, I've had screen flickering issues. When connecting, the external display turns on and off rapidly causing the main display to flicker as it's loading/reloading the monitor. I've had this happen with two separate, brand new USB displays. I noticed that this also happens with the on-board HDMI output as well.

I recently picked myself up a Kensington SD5300t Thunderbolt 3 docking station thinking this maybe, JUST MAYBE, bypass this issue and of course it doesn't. I've reinstalled the Intel drivers & the NVIDIA drivers to get the flickering to stop. I know it's not related to the most recent update because it's been happening for over 2 years.

I noticed something new today though - the displays tend to only start acting up when there's a lot of deep blacks on the screen. If I change the app color settings to dark, the entire display shuts completely down until I close the settings reverting back to my desktop. It also happens on any webpages that have deep black/blue colors on them. I'm wondering if this long-standing issue is having to do with color issues and the on board GPU. 

Does anyone know of any workarounds to this? I've read through a million forums and everything says either reinstall the drivers or wipe the computer.
