Second screen for dashboard, no dimming

[Larus]

I have a second screeen next to the laptop. On this screen you can duplicate or expand the laptop screen.
I want to expand and use the screen for different dashboards.
This works nice with all nmea data on one screen and the charts on the other screen.
However F5 and F6 (night vision) doesn't work on a expanded 2nd screen.
Any idea how to solve this?

Larus..
I've tested with two screens. Windows is expanded to the other one and it works very fine. My second screen is a HDMI connected TV.
For example I have OCPN on the PC screen and Dashboard on the other and both are dimmed using F5 and lightened up/down using F6.
But, remember F5 only affects vector charts like CM93 not raster charts. For raster F6 is the only way to decrease the light.

Thanks Hakan,
(I was away a few day's).
Expanding via HDMI on my Tv works better than monitor, F5 is OK now, however F6 still doesn't work.
Givven your experiment it seems no ocpn problem.
Do you know how F6 works? I don't think it affects the backlight.

On the laptop I can dim with a Fn combination and I think this does change the backlight. In fact F6 and Fn are supplementarry, you can dim to a black screen.
On board reducing backlight also reduces powerconsumption so that is preferrable.
The Fn on the laptop affects only the laptop, not the expanded monitor. I will see if I can change the backlight of the monitor otherwise.

Larus...
Your conclusions seems relevant.
I'm not sure of the F6 function but I've experienced the same double function of F6 and system back light. And, yes, decreased back light is saving power.
