Just because the individual pixels have a Xhz frequency, doesn't mean that the whole screen has to - depending on how you do updates. I could, for example, update a different quarter of the screen at (4 * X)hz, which would introduce a bit of temporal blurring, but would normalise reasonably fast. With something like a cursor movement, they're often blurry anyway and it's not really an issue. With text entry you can drop your latency, but changes would fade in (in quarters like everything else). You wouldn't have to go with 2 * 2 updates, the larger the blocks the more quickly the fade in would start, but also the blurrier the screen would appear. Of course, the smaller the pixel size you're working with, the larger the block size you could reasonably use before things start looking too bad.
