kvmd-edidconf --set-monitor-serial=[MONITOR_SERIAL] doesn't work on PiKVMv3

[mareksagan]

Describe the bug I cannot change the Monitor Serial number using kvmd-edidconf tool.

To Reproduce Steps to reproduce the behavior, like:

1. rw
2. kvmd-edidconf --set-monitor-serial=123A
3. This error occurs: Traceback (most recent call last): File "/usr/bin/kvmd-edidconf", line 8, in sys.exit(main()) ^^^^^^ File "/usr/lib/python3.12/site-packages/kvmd/apps/edidconf/init.py", line 377, in main getattr(edid, cmd)(value) File "/usr/lib/python3.12/site-packages/kvmd/apps/edidconf/init.py", line 188, in set_monitor_serial self.set_dtd_text(0xFF, "Monitor Serial", text) File "/usr/lib/python3.12/site-packages/kvmd/apps/edidconf/init.py", line 195, in set_dtd_text index = self.__find_dtd_text(d_type, name) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/kvmd/apps/edidconf/init.py", line 204, in __find_dtd_text raise NoBlockError(f"Can't find DTD {name}") kvmd.apps.edidconf.NoBlockError: Can't find DTD Monitor Serial

Expected behavior Monitor serial should change but it doesn't.

Serial and Monitor serial are two different type of blocks. Use --set-serial, like: kvmd-edidconf --set-monitor-name=TOSHIBA --set-mfc-id=TTP --set-product-id=34953 --set-serial=2290649089 --apply.

This is a EDID legacy.

But I want to be able to set a monitor serial and serial independently. How do I do that?

[mdevaev]

kvmd-edidconf is able to configure only those blocks that are already in EDID, with the exception of Audio. This is not a full-fledged editor. If you need more, use the AW EDID Editor.

I tried opening the tc358743-edid.hex file with AW EDID Editor but it gives me this error... Do you know how to fix this one please?
