No video output after boot up until replugging the HDMI

Hey guys, I finished a build, everything seems to be working but I have an issue that when the system starts I get "no signal" on the monitor. I've found that it starts to work when I unplug and plug the HDMI back in. Weirdly enough, it starts fine on a 1080p monitor, only on the 4K monitor I have to do the replugging.

My build: MB: GIGABYTE Z390 Designare CPU: i9-9900KS GPU: SAPPHIRE PULSE Radeon RX 590 RAM: HyperX Predator 2x16 GB 3000MHz CL15 SSD: Samsung 860 QVO 2TB PSU: EVGA SuperNOVA 850 G+
