I have several monitors which are the same model; for example, two Dell P2422H monitors. When I print the VCP capabilities, I don't see any information that distinguishes them:
{'prot': 'monitor', 'type': 'lcd', 'model': 'P2422H', 'cmds': {1: [], 2: [], 3: [], 7: [], 12: [], 227: [], 243: []}, 'vcp': {2: [], 4: [], 5: [], 8: [], 16: [], 18: [], 20: [5, 8, 11, 12], 22: [], 24: [], 26: [], 82: [], 96: [1, 15, 17], 170: [1, 2, 4], 172: [], 174: [], 178: [], 182: [], 198: [], 200: [], 201: [], 204: [2, 3, 4, 6, 9, 10, 13, 14], 214: [1, 4, 5], 220: [0, 3, 5], 223: [], 224: [], 225: [], 226: [0, 2, 4, 14, 18, 20], 241: [], 242: [], 253: [], 254: []}, 'mswhql': '1', 'asset_eep': '', 'mccs_ver': '2.1', 'window': '', 'vcpname': '', 'inputs': [<InputSource.ANALOG1: 1>, <InputSource.DP1: 15>, <InputSource.HDMI1: 17>]}
I checked and this output is identical for both monitors. How can I distinguish them other than the index? For example, in another software "Nirsoft ControlMyMonitor" I get a serial number of some kind as well:
In Nirsoft ControlMyMonitor, I can address the monitor by the number in the red box directly, which makes it possible to distinguish them when controlling them.
It would make more sense to identify them this way since monitor indexes in Windows can change, especially as I add and remove other monitors. The indexes are not consistent in my experience.
I have a setup with 8 total monitors on Windows 10, Python 3.8, monitorcontrol==3.0.2.
