the size of screen is not relative.

it's only about resolution. if your screen or gpu cannot display/render at a higher reso, then you can't squeeze any morepixels in to that same inch^2 area.

higher resolution will actually make things smaller on the same sized screen.

a 1080p resolution on any sized screen will always show exactly the same on-screen image.

another tidbit.. if your screen is X*Y resolution, it will always display at that resolution. it's always upscaled or downscaled to fit onthe screen in full. otherise you'd get black bars around lower reso's or a large amount of overscanning and lost portion of the image.
