This is a real technology problem. For all the wonderful advances in

You could do it with say a 1200x1600 display, but for marketing
reasons nobody is going to make a 1200x1600 tablet with a screen size
that is desirable for cockpit use, probably 8" diagonal.

800x600 tablets have been around for ages. The old Fujitsu LTP600 is
popular with a number of pilots I know, for JV.
