Our application is written in C++ and runs on Ubuntu. I need to scan all the connected HDMI devices and obtain information such as device model, serial number, etc. Can someone please point me in the right direction? Regards.

    See [How to create a callback for “monitor plugged” on an intel graphics?](http://stackoverflow.com/q/5469828/11654). Also check for files with `hdmi` or `extcon` in their name in `/sysfs/`. – CL. Aug 18 '16 at 10:25
