Many OLED monitors and TVs already do this, it's called pixel shifting.
A Panasonic Viera plasma TV I bought around 2012 also had this feature.
Samsung solves this in the TV itself. It can be annoying when the edges of the screen are ever so slightly off, but i'm glad I don't have to worry about it. QCQ90S. I wouldn't recommend it since the tv's gui is glacially slow, but then again all the ones I tried last year were.
