The LG Digital Signage screens have an operating system called WebOS (which is pretty much a Linux-based OS) and like any digital device, there are software firmware upgrades you can install to fix issues, upgrade operating system files and even add new features. Unlike other electronic devices, LG doesn’t have a public website where you can download the latest firmware but you need to have a developer account on the LG webOS Signage Developer website: https://webossignage.developer.lge.com/

Once you log in, there is a search function to search for the model of the LG digital signage screen and the link to download the firmware.
