Is Jellyfin Media Player installed on a separate computer (not directly on the NAS with the 5600G)?
This issue doesn't involve the CPU on the NAS if it's not being used to transcode. Most modern CPUs will not struggle to just send a 4K file to a client.
On Jellyfin Media Player, go to its client settings and try changing the GPU decode settings. There are 3 options to choose from. Most likely, JMP'S built-in MPV player is not handling the CPU or GPU in the system correctly.
