Well after long research and deciding not to order a custom made tablet from China, I purchased the Samsung Tab S2 9.7". The brightest tablet I could find. (Auto outside brightness up to 684nits) I also just ordered a NuShield DayVue screen cover. This should allow me to have full brightness/sharpness/color in direct sunlight! I will post pics of the direct sunlight shot once the shield comes in! If the sun is out tomorrow I will post a pic of what the screen looks like in direct sunlight with the brightness turned all the way up and no "nushield" on it. I am very surprised on how well I can see the screen already in the direct sunlight, its quite impressive. I have an iPad Pro as well and this beats it!
