How to identify monitors about monitorcontrol HOT 5 OPEN

At the moment there is no way to identify unique monitors, this would be a good feature to have though.

I'll accept a pull-request, but I will not be working on this for a long time, I made tons of commitments for other projects people are waiting on.

Thanks, I understand. And thanks for this library.
I may have a go at some point, can't at the moment though.
I will need to learn a bit more about I2c and the Windows APIs.
Just a few notes that may help anyone (me) trying to implement this.
On Windows, we might want EnumDisplayDevices and the DeviceID member of DISPLAY_DEVICE structure, as long as there's a way to cross reference this with a HMONITOR or some other info returned by the EnumDisplayMonitors API which we are currently using. Haven't found that yet.
Another possibility on Windows is WMI, apparently some monitor info can be read from there. (Either wmi python module or shelling out the wmic command line tool).
On Linux, it looks like EDID can be read from the I2C bus at address 0x50.

Looks promising! The "DeviceID: Not used" remark is a bit annoying, but since it is 128 bytes you're probably right to assume this is the EDID.

Yeah Linux is much easier in this regard, I have 3 identical monitors, and the EDID hexdump from ddcutil detect -vvv returns deterministic unique values for each monitor.

Identification should be added. Currently --monitor 1 or --monitor 1 are constantly changing

If your monitors are of different models or input types (dvi vs hdmi), it can be identified by the model & input field from monitor.get_vcp_capabilities().
