IDU Dimming

[Mariano]

Hardy,

On the 767, the ADIs, HSIs, and both EICAS displays cannot be fully dimmed (CDUs can). There is always a faint display left (not burn-through).

I wonder if this is the same on the 744 (I noticed that I can fully dim all IDUs in PSX, so I assume PSX is right ;-).

Just checking.

Best regards,

Mariano

I can't remember what our 767's were like, but I have a video of a 744 CRT display during a brightness check. The screen looks completely black. The test looks like it was carried out in daylight, so even the light sensor inputs haven't make the displays appear.

PSX OK

Just a thought re light sensor: I think the light sensor induced brightness increase is not an addition but a factor, e.g. factor 1 at night, and factor 3 in sunlight. Multiplying the manual setting of zero by factor 3 will make no difference. So when the knob is fully left, the sensor cannot influence the screen, neither in sunlight nor at night.
