nope, sorry you're stuck with native resolution(s)
lcds have "fixed pixel displays". meaning its basically a grid of blocks; a 1920x1080 would mean 1920 block across with 1080 block down. but i think you know that. the blocks don't move and thats why images appear blurry when using a different resolution; the outline (or really a line) is in the middle of a pixel and it cannot display two colors at once.
i think it might be similar to raster graphics, where what gets displayed is based on a block design. whereas vector graphics; what gets displayed where, is based on curves - and that would be similar to CRTs; which would shoot a beam of electrons to the screen and could be more dynamic.
sorry didn't mean to be so
hope it helped.
