I have a Matek F405-SE FC running arduplane 4.2.3, i have a DJI vista connected to it for OSD. I have configured msp displayport with settings MSP-TYPE=5 & SERIALX_PROTOCAL=42, and it will not display an OSD in the goggles. I’m using the fpv-wft.
btw I have this same setup on 3 other arduplanes and 4 copters and everything works with full OSD!
