I'll have to build this sense code adapter tomorrow to make sure it works on the MX (I'm sure it does)! Absolute genius life saver. I thought I was going to be stuck with this thing only semi-working!
Ha, glad to help out!
I think you should be able to use most sense adapters - the formula is, find the switch setting for Multiple Scan 16” (which gives the diode between SENSE2 and SENSE1, but with SENSE0 grounded), and then remove the switches that are common to 13” RGB (which grounds SENSE0).
For example, on my adapter, Multiscan 16” is 148, and 13” RGB is 14, so I get 8.
That should give you sync on green with the right sense code. You may have to fiddle with other switches to change the sync mode (6 and 7 on my adapter), but often adapters with smaller numbers of switches may hardwire HSYNC and VSYNC anyway, which should work with any monitor.
