One of the key connectivity features is USB-C with up to 15W Power Delivery. A compatible laptop or device can connect to the monitor using USB-C for display connectivity and power delivery. LG specifies that the required USB-C cable is not included and is sold separately.

For comfortable viewing, the monitor includes Reader Mode and Flicker Safe. Reader Mode adjusts color temperature and luminance for reading, while Flicker Safe is designed to reduce invisible screen flickering. The monitor also includes Super Resolution+, Color Weakness, Smart Energy Saving and Auto Input Switch features.

The LG Switch app provides additional productivity options, including the ability to divide the display into multiple sections and customize monitor usage. Dual Controller support also helps users manage compatible computers from a single setup.
