dpi stands for "dots per inch", it can't possibly be expressed in
millimeters, it must be a quantity. You probably mean one pixel is
0.51 millimeters, making for a dpi value of 25.4/0.51 or roughly 50
The term for that measure is "dot pitch" and it's not the size of the
pixels (their light-emitting area) but rather the (slightly larger)
distance for a given edge of one pixel to the corresponding edge of the
immediately adjacent pixel. While it need not be the same vertically
and horizontally, nowadays it usually is.

If you multiply the dot pitch by the number of pixels (in a given
dimension) you get the physical size of the imaging area of the
display.

Leaving revisionism aside for a second, in the previous mail the abbreviation DPI was used by Basil, not DP,

Just to make the point, here is what I wrote in the first post:

"on a TV I think the (?)dpi is something like...."

(note the (?) before the dpi?)

and then I wrote:

"The resolution is 1366x768 and the dp is 0.51mm."


with the same values in millimeters.
