A:Answer There is one port on the Lenovo Chromebook Duet: a single USB-C port that's capable of 18W (9V/2A) charging and 1080p 30Hz video output (though you'll get bumped down further to 720p 60Hz on most monitors). You will be able to connect external devices that are compatible with the Chrome Operating System and Google Play Store APPs. We recommend you check with the specific software publisher's web site and hardware manufacturer's web site of the APPs and hardware you want to connect,. for their compatibility with the Chrome operating system and the minimum/recommended hardware requirements (Is a Graphics card required, the processor speed and the minimum required system RAM and the minimum available hard drive space) to run their program, then compare those requirements to this system's configuration.
