Is there a known bug after the latest SU that caused blank screens with GTN 750 primary and secondary us i g b36p, a36tc, a36 aircraft. The GTN 530 works just fine. I even tried just the GTN 750 on primary but no display.
I have both, but I mostly use TDS. I’ll give PMS another try with the latest version next time I fly one of the BlackSquare aircraft. As far as I remember, the last time I used PMS it worked just fine as well.
