B550-I Gaming won't boot on 4k display

Curious if anyone else has had issues booting on a 4k display with the new Ryzen series CPUs on a B550-I Gaming MB. To get around the issue, I have to boot with a 1080p display and then I can switch to the 4k TV and everything works great. I recently upgraded the CPU from a 3700x and I didn't have this 4k booting issue. I also have issues with random shutdowns/reboots as well (again... only an issue that started with the CPU upgrade). Any ideas? Thanks for any help.
