The hardware compatibility list does not have screen sizes and it’s a lottttt of data to get through. Does anyone know of any 17+ inch laptops that can run 4.2 without any (or with minimal) issues?
Budget is flexible, but prefer something rugged/sturdy
There are some Dell big screen that work with 4.1. Keep in mind that a laptop is dependent on battery and environment of use. My last year of purchasing laptops I went through 6. Salt water air, waves (shocks) etc… Used desktops are the way to go. You can buy a small PC and a HDMI cable.
There is a Nitrokey laptop with a larger screen,
a rugged laptop would be suitable for you
