Measure the width of the screen (not the diagonal) and the height of the screen. Just the visible area. Divide the width in inches into the width in pixels. Do the same for height. For example, if the width is 20" and the pixel width is 1920, then the dpi is 96. You should get the same answer for height.

There is no such thing as 'dpi for screen'.
dpi stands for dots per inch. Monitors display in pixels, not dots. Printers display in dots. I think what you're looking for is ppi (pixels per inch).

Macs display at 72ppi, PCs are 96ppi (could be 92ppi - can't remember).

Shhhh! Don't make Steve look foolish. He didn't get that memo, either.

Nope. The OS-X user-interface geniuses "never got the memo" about high-resolution
displays, so Mac UIs all assume they're running on a 72 ppi, bargain-basement CRT.

...that's why all text is displayed ~ 30% smaller than the correct point size,
