A:Answer The HP x360 14 has what every modern laptop has these days: USB-C ports that can move data at rates over 5Gb/sec. Just as with a MacBook etc. you'll need to get an adapter to provide USB-C to HDMI (or DisplayPort, DVI, or VGA etc.) capability. The adapters start at about $15 on Amazon. I'd recommend that you spend around $35-50 for a USB-C adapter that has at least one additional USB-A port, and the ability to keep charging your Chromebook while using the adapter via power pass-through to the USB-C.
These adapters are plug-and-play. USB-C is very flexible and very capable way to configure the ports you need. USB-C docking stations can give you a single-wire hookup to the HP x360 Chromebook for all of your external stuff: mouse, keyboard, monitor, external disc drive etc.
