DVI single link is limited to 165 MHz and 24 bits per pixels.
DVI dual link is not limited, excepted by the copper and both ends.

But the reality of a 20" display at 326 dpi, for 2D, is not useful.
For hand held, 326 dpi is fine (very fine).
For a 20" display, that would make the pixel unreadable.
(usual pixel size is between 0.2 and 0.3 mm, which is about the
classical 72 & 100 dpi of fonts)
Pushing to 200 dpi in 20" would still be a frivolous move.
