I don’t have a Chuwi VI10 to comapre, but I find the EZB 3 Pro perfectly usable even in outdoor conditions. The combination of the brightness and matte display make for a well viewable screen. I personally hardly ever use the 100% brightness, only when I am outside in direct sunlight.
thanks for the answers. i was asking for 100% brigthness in outdoor situation. The chuvi vi10 tablet was not bright enough. If this screen is darker it would not be usable for me.
