AI upscaling 4K TV?

Hello, Quick question. I have the following TV: https://www.otto.de/p/samsung-gq75q70bat-qled-fernseher-189-cm-75-zoll-smart-tv-quantum-hdr-quantum-prozessor-4k-supreme-uhd-dimming-1603957062/#variationId=1603957063 How exactly does AI upscaling work? Do I have to configure something on the TV, or does it happen as soon as an HD or SD card image is detected? Does it also work via the standard HDMI input?
