i feel dumb for having to ask this. how do i make what appears on my screen larger? with a larger screen, i can make things out alright, but this 14" screen is terrible for my old eyes. and reading glasses do not help, unless i set the laptop on my chest. i have tried the magnifier, and that is pain to use. so i THINK i want to change the screen resolution?? is that right? and if so, what way do i go?
