A:Answer Hi Bob! This will come with a USB and HDMI cable that you just plug into your external device (laptop, desktop, or all-in-one). Depending upon your external device, you will probably want to consider a keyboard and mouse as well. If you need additional USB ports for these items, you can purchase an adapter that give you multiple ports. If you need any assistance with your purchase, the Geek Squad can assist remotely! https://www.bestbuy.com/services/remotesupport
