Hello I am having a problem with brightness win7, xp10.51, I have turned the manual offset to -10 % but the level still shows 100% in the backlight tab anyone with ideas please.

 

 

the level still shows 100% in the backlight tab

 

I'm not sure to understand what that is. Can you please clarify?

 

More generally, Integral lighting is controlled by X-Plane itself and is general to all gauges in the panel. Most often, there is a rheostat for this on the panel somewhere.

 

"Manual offset" is per-GTN gauge. This is a local adjustment that adds/subtracts from the general integral lighting level.

 

Furthermore, the "pilot" side GTN reads the first X-Plane integral lighting dataref value, the "copilot" side GTN read the second X-Plane integral lighting dataref value. These values are in an 'array' dataref, i.e. pilot is index #0 and copilot is index #1 in the array.

Thanks for the prompt reply Jean-Luc wish I could figure out how to paste a picture here, as that would show things better, I have turned everything down and it is still glaring, will play around with the gamma take it down from 2.2, the manual offset wont go below -10 but on the other side it seems to climb enough to white out the screen, may be  videodriver thing  I have a AMD card, and recently just now I got the 650 as well but that does not switch on yet to investigate that  

You might want to try in different aircraft to see if this is aircraft specific or plugin specific. This might help pinpoint the culprit.

Success it was the instrument lights had to assign a button on the joystick both the 750 and 650 work together now just understanding how to actually use them.

Further to add to the the brightness thing I notice that the offset in the the backlight thing, only goes to -10% limit  but on the other side you can go plus 50% whatever , as my problem is solved it leaves the instrument lights dimmer sometimes than what I would like, does the real thing which of course I have never seen ,touched whatever limit the backlight to -10%, and also I have put both the 650 and 750 into xplane 11 and they work just the difficulties of the menu entries being spread all over which will probably be a laminar thing, but anyway its cool. Look forward to the 430/530 coming out I got the one for fsx yrs ago and it was the best.

It looks like this is a GTN limitation: -10% to +100% only, which would suffice in the real world.

 

However, there is a difference in the way XP10 and XP11 manage the datarefs related to integral lighting and it may be there is a bug in our implementation as well. I'll look into this, thank you for your patience.

Yes thanks Jean-Luc ,so its a real world limitation, I have managed to get the brightness thing under control now, but it leaves a dilemma of having the instruments dimmer than what I would like to make the the gtn's 650 and 750 acceptable,not badly so however, ie its not a game stopper

The latest GTN v2.3 update now scales the negative brightness values by a factor of about 4, that is -10% in the GTN is roughly -40% luminosity!
