4K Display Constantly Cutting Off - Opencore Catelina

Hey I've just fully installed Catelina on my PC and has seen no issue with it. However, I purchased a Dell 4K monitor a few days ago and the DP signal started to cut off constantly. The problem does NOT occur with my old 1080p monitor however, only 4K.

Details

PC Specs:

i5-10400

UHD Graphics 630

16G RAM

250G SSD

Monitor: Dell s2721qs

Problem:

What is happening now is that Opencore boots up fine. However when the OS is fully started, the DP signal starts to cut off every 5-6 seconds or so. So basically the monitor says no DP input and after 1 second there is input again, and after 5-6 seconds it says no DP input again.
