5 Ports to Know on the Lenovo ThinkCentre M730q
HDMI 1.4b and VGA Regarding the Lenovo ThinkCentre: The rear panel uses HDMI 1.4b and VGA, not modern HDMI 2.0 or 2.1. This means 4K at 60 Hz is not supported over HDMI.
DisplayPort 1.2 The DisplayPort 1.2 is the best port for sharp output. Use it for your primary monitor.
Front USB-C and USB 3.2 Gen 2 The front has one USB-C and two USB 3.2 Gen 2 Type-A ports. These are fast for connecting peripherals or transferring data.
Rear USB 3.2 Gen 1 and USB 2.0 Around back, there are two USB 3.2 Gen 1 Type-A and two USB 2.0 ports. Use the USB 2.0 ports for keyboards and mice to save faster ports for other devices.
Gigabit Ethernet and Combo Audio Gigabit Ethernet is included for wired networking. A combo audio jack on the front handles headphones or a headset.
