Using a USB Type-C/lightning to HDMI cable and a HDMI input to output adapter, you can connect your smartphone with your laptop’s display. There are also apps like TeamViewer QuickSupport, Vysor, ApowerMirror, and AirDroid that let you wirelessly mirror your smartphone into a PC. These days, brands like Apple, Motorola, and Samsung have come up with their own software (AirPlay, Ready For Assistant, Samsung Dex) to help you easily cast smartphone screens on PCs.
