I've had this happen with several aircraft now.  It occurs as the sky darkens (today btwn 6:40 pm and 7:00 pm).  The screens go dark and I can no longer continue the approach.

I should add that when adjusting the brightness (menu access on PFD) and reducing the levels before it gets dark the screens stay on. Once they go blank, the menu isn't available - the only way to continue is to "turn back the time" to get the screens back on.

Randall, did you ever get a response to this issue. It is now Appril 2023 I have started to have the same issue with the G1000 in the Beech G58.. Any suggestions other than the brightness setting? Any thing fron Working Title or MSFS Support? Thanks for any information.

I've never received any other responses on dealing with this issue.  I also haven't been flying at or after dusk for a while, so I can't verify that it's still occurring.

When I suspect I will be passing through dusk to darker skies, I lower the brightness levels a small amount as part of my preflight checklist.
