AspectRatio -> Automatic will work (regardless of the physical
characteristics of the monitor used).
For instance,
Plot[Sqrt[1 - x^2], {x, -1, 1}, AspectRatio -> Automatic]
(Note that the default values for AspectRatio is 1/GoldenRatio, i.e.
0.618034..., ratio which is supposedly to be more aesthetically
pleasing, and so since the Antiquity.)
