The ASUS PN51 offers three display outputs with a versatile USB-C port

The PN51 steps up from the PN41 with three display outputs: two HDMI 2.0 ports and one DisplayPort 1.4. It also adds a USB-C 3.2 Gen 2 port with DisplayPort Alt Mode, so you can drive a fourth monitor through that if needed. USB-A coverage includes two USB 3.2 Gen 2 ports and one USB 2.0 port. Networking bumps to 2.5 Gigabit Ethernet. It’s a versatile little machine that can handle a multi-monitor setup without breaking a sweat.
