Classic C172 - Both Garmin units not readable at night

[Kryul]

On the Classic C172, during daytime both Garmin units are on and readable as normal.
While still on at night, both units are very dim and unreadable.
I have used all of the light switches to adjust the lighting. Even the two on the roof.
But none will make any of the Garmin screens any brighter.

I have this problem with a few aircraft as well.

This seems to be a legacy aircraft problem, I have the same issue with the Carenado C170B

I have a support ticket with them and this is all they said

I have the same issue with all of my Cowan Simulation helicopters too.

I changed the flight from night to daytime so I could see the Garmin units.
With a lot of trial & error I found a page on each of the units that allows the displays to be changed from Auto and Manual brightness.
I changed both to Auto and that seems to have sorted the problem for that flight anyway.
Don’t know if the brightness setting will be saved for future flights though.

Well, dang… I gotta try that. Thanks!

I think that works for some. The new Savage Norden from Got Friends gets crazy high brightness and bloom on the screens at dusk and dawn, it has a manual and photo cell brightness mode which helps sort the issues there

Unfortunately the C170B has no alternate settings it just has a brightness slider that’s already at max

Well, ■■■■… didn’t work for my CowanSim 500E.

I filed a formal bug on this. It seems worse at twilight. Feel free to chim in… the more apparently the more likely to get attentions… maybe?

I cross-referenced this thread.

Sorry about that with the 170B. This was one of the major bugs for 3rd-party addons. Asobo changed the lighting formula so daylight is so much more bright than night. You can look at it as MSFS 2020 had the wrong lighting formula so we need to change.

I have been working on making the T206H MSFS 2024 modular and I just recently solved the avionics brightness. It’s a very different approach that does require a sensor so you can scale the light values. We have two different SinVars, GLASSCOCKPIT AUTOMATIC BRIGHTNESS which handles day, dusk, night and dawn. Then we have AMBIENT LIGHT SENSOR which shows the modern units and if it’s overcast.

It’s just that the daytime lighting is now 10,000 brighter than at night. A totally different magnitude.
