Anybody could tell me how the "nits" related to the standard measure
of Luminance "cd/m2" (candela per square meter) ?
I have seen in this forum, that for example the brightness of the
Clearnav and Ultimate is about 1000-1500 nits as somebody said, but
how much is in cd/m2 ?
A TFT screen with 300 candela per square meter is readable in direct
sunlight ?
Maybe stupid questions ?

Google "nit candela", click on the top link. Pretty easy.

A nit is a candela per square meter.

What is readable in direct sunlight is not just captured by the nit
rating. A lot depends on contrast, type of display, surface
reflections, color properties of the display, and especially *your*
eyesight. So if screen visibility is a big issue to try to find a way
to look at the displays.

Bottom line, I've had no trouble reading the ClearNav display in the
cockpit through sunglasses with dense mountainous terrain displayed.
Better than anything else I've seen.

Getting enough screen brightness to be viewable in direct sunlight is
relatively easy. Doing it at a reasonable current draw is the hard part.
Most of these 1000 nit plus screens draw around an amp at full brightness.
