Tony,
I contacted the vendor and asked about a brighter screen option because I have tried several laptops in my RV (linked to the wing camera) which have essentially the same brightness. My experience is that on a sunny day, I cannot see much of anything on my laptops (400 nits brightness), even with some shading. For comparison the Dynons with bright screen option are 800 nits and are fine for visibility. I certainly like the idea and the price, but am concerned about the visibility at 350 nits. At this point, there are no plans for a bright screen option.
I would be interested in a report back on the visibility if anyone tries one of these. Perhaps a smaller screen (than my laptop) will make a difference and it will be more visible than I expect.
cheers,
greg
