I installed the SimAppPro and connected the PFP 7. All the lights work, but the CDU display will not show any of the CDUs on the PMDG 777. When selecting the "Environmental Check" tab in SimAppPro, the "Simulation initialization phase" and the "Aircraft module name retrieval status" lines are red, all other lights are green. It shows the "pmdg 777-200lr" next to the retrieval status line in white letters. The Winwing CDU displays "WINWING" on the screen, but the aircraft CDUs will not display. I updated the device firmware prior to starting the sim. Are any of you using this device? Thanks.

I'd suggest Winwing would need to update SimappPro for the LR. I use a Mobiflight profile on MSFS 2024 which works very well so maybe see if you can find one compatible with P3D?

FYI, I also solved this by switching to MobiFlight and using a profile downloaded from flightsim.to.  For the display to work, there is an ini file that needs a few lines added.  For details, search for WinWing on the MobiFlight compatible devices page. Fairly easy though.

I've raised a ticket with winwing about the LR and Mathijs Koch at PMDG is chasing as well. maybe if a few more people put a ticket in with winwing they'll update SimAppPro
