That's why I'm using a device with an e-ink purely-reflective display: in that case, more incident light does not change the contrast at all. |

The Craggy Aero Ultimate, Ultimate Le, Ultimate Le 57. My first sale was to a customer that saw the display in my glider, the display was in the shade no direct sunlight, colors looked great. Then he said turn the glider so the sun is on the screen. I turned the glider and there was a shade line from the panel cover on the panel but it was not seen on the display. Then I turned down the backlight little change, shade line still not visible on the display. A true sunlight readable display. It has the following specifications extremely high contrast ratio, two specialized coatings and an adjustable backlight.

I.e., if you were to turn the backlight completely off and shown a flashlight on it, could you see the info on the screen clearly? Then that's not what I am talking about. Rather, I am talking about display types that have no backlight but rather each pixel generates its own light. I believe all recent model cellphones are like that. With enough ambient light, these displays lose contrast. |

I have a Nexus 7 which would also work for running the program but
it's absolutely useless in direct sunlight.Â* I considered making a sun shade for it, but found THIS I use the Nexus 7 all the time and never have a sunlight issue - Are you positive you went into setting and have it manually set to full brightness? The default allows the tablet to adjust.... it needs to be set on full. Best $130 bucks I have spent. I have 2 Nexus 7's and both work great! WH |

Thanks, I'll try that!
I just tried the sunshade outside in the NM sunshine and it works well.Â* I think I'll start it up again, check the brightness, and go back outside.Â* I'll report back.

How does the sunshade impact your ability to use it as a touchscreen device? I worry that it would be more awkward, especially when trying to brace your hand against the bezel to steady your finger as it selects a screen element.
But I haven't tried it. Chip Bearden |

That worked really well!Â* Not as bright as my ClearNav, but certainly
readable.Â* With my sunshade installed it should really work well. I was really tired the glacially slow performance of the Nexus 7 2012 with Android 5.1.1 so I found a way to root it and then flashed a pared down custom ROM.Â* It now boots in 40 seconds, has no bloatware, and is really fast.Â* The ROM is SLIMKat.Â* Look it up if you're a tinkerer.

You have to reach in pretty deeply but that shouldn't be much of a
problem for my application.Â* I plan to run Avare on it and feed that from an XGPS-170 WAAS GPS and dual band ADS-B In receiver.Â* This will be in my Stemme and I can set it up before takeoff and never touch it again throughout the flight.Â* If I needed to manipulate it a lot, the bottom section of the screen is removable which would allow my whole hand to get in there.Â* Unfortunately, my Stemme is down following a prop strike and it may be a while before it gets back in the air.Â* Waiting on parts...

It does work very well and is equivalent to my wife's Samsung S8+. Open box new for $130.00. Thank you everyone for advice and info. Mike |
