Resolution is not really the problem. When it comes to that, assuming the RGB horizontal rectilinear subpixel arrangement that dominated the lanscape, having higher resolution just means you could pack more text onto a given screen. But if you were to send militext to, say, a pentile display, it comes out as unrecognizible mess. It'd also not work with CRT displays, even vertical mask Trinitrons, because, albeit the phosphors may look like subpixels, they're actually "just" sampling points along image lines, traced out by an electron beam, and each digital image pixel would cover several phosphor pitches and not change apruptly.
