To better describe my issue, I captured a video of my problem here: https://youtu.be/50m_Ddq_AW4
I'm wondering if any of you technical ppl here know what's causing this, and how I may fix it? The problem goes away if I choose 1080P on the Xbox, this display flickering and the blue lines only happens at 4K. I'm using a HDMI 2.0 cable from the console to the monitor, and the monitor works fine with other sources at native res over HDMI and DP.
