Even with edid patch I don't solve the problem. I've been back working with rehabman's kext trying to figure out what breaks its function since 10.13. Analyzing ioreg (attached to the 1st post) I notice that from 10.13 a new apple driver is loaded, I believe this causes the PNLF control to break with kext rehabman. Obviously this leads to nothing since without that kext the bar never appeared in the monitor menu.
