Screen size selectable

Hi !
it would be great to have an option for selecting a particulate size screen, on my case there are not any tablet which will fit ok on my dash space, this problem could be solved using a bigger tablet and beeing able to reduce screen size to whatever measure we need.

for example 260mmx 130 to 250x90


any chance for implement sth like this?
or maybe someone know how could be possible to reduce image size on an androit tablet ?
