AltGr to export PFD or ND

Sorry, on 737 PMDG or 320 FBW, I generally exported the PFD or ND to another monitor using AltGr for convenience. For a while now, when I’ve been trying to open these windows, they no longer open, or better, they certainly open somewhere, but I can’t see them anymore. Same thing on 172 or ATR. Suggestion please? I say that they certainly open because on the 172 G1000, when I opened the right Map Display, I realized that there was a small frame on the base of the main monitor, I lifted it and the map display appeared. There should be a way, which I don’t know, to reset these views. I hope I managed to explain my problem. Help me please

It’s a bug with the sim when you change your monitor arrangement without first closing the popped out windows. The good news is until it gets fixed you can use Pop out Panel Manager to reset them to 0,0 which will be top left of your main monitor. The other solution is to re-establish the screen area that was there before and move them back yourself.

Thanks. Sorry, but what does you meen exsactly with “ Pop out Panel Manager”. Where can I find this pannel?

Pop out Panel Manager is a free application used for the automatic control of popout windows in MSFS. You can find it on flightsim.to.
