Problem solved! I bought a Riupro Fiber Optic Active HDMI cable. I did some research and this cable was one of the best tested for the distance I needed. I was bandwidth restricted to 4k 30 hz before, with this cable I can display 4k 60 hz, and it fixed the problem.

Thanks for the update! Here's the cable on Amazon if anyone is interested: https://www.amazon.com/RUIPRO-4K60HZ.../dp/B07L3CHPDR
