The Beelink SER5 relies on dual HDMI for display output — USB-C is data-only

The SER5 handles display output through two HDMI 2.0 ports on the rear — no DisplayPort here. The front USB-C port is data-only, so don’t count on it for a third monitor. Up front you get two USB 3.2 Gen 2 Type-A ports and a 3.5mm headphone jack. Around back there are two USB 2.0 ports for slower peripherals, Gigabit Ethernet, and the DC power input. It’s a clean, budget-minded layout that gets the job done without any fussy configuration.
