The human eye can see things that are much smaller than what it can resolve. You don't need to be able to resolve the individual dots on a screen to be able to see the difference that a higher DPI screen makes.

The "resolution" of the human eye is often given as one minute of arc, which corresponds to about 344 DPI at a distance of ten inches.

However anyone with normal eyesight can easily see Mars, which has an apparant size of 25 seconds of arc at its closest approach, equivalent to one dot on a 825 DPI display at ten inches.
