I need your wicked skills for my question.
Basically, I have a casing I want to use to fit in 7" 4:3 screen. I spent good time looking for 7" LCD screens. But I can't seem to find any. Naturally, my choices came down to either fitting in smaller screen or larger screen.
I prefer putting in larger screen to maximize the screen area.
In order to solve this task, I have a question I woiuld like to have it answered. Is it possible to resize the display area on LCD screen?
I tried to illustrate it on the quick chart I made below.
