Surprisingly, your visual perception of something can actually be affected by how big you think its image is, even if it is not live. The "vertical-horizontal illusion" is an optical illusion where a vertical line appears to be longer than a horizontal line of the same length. It turns out that this illusion is more pronounced in larger images, even if the image has the same content. In fact, some researchers used monocular VR to show that your perception of horizontal vs. vertical scale can be altered just by making you believe that the image you are viewing is scaled to a TV vs. a movie theater screen -- even when you are constrained to view exactly the same pixels in both cases. I have a pet theory that this may be why film stars thought that TV cameras "added ten pounds"... Viewing a face at smaller-than-life size could make you perceive it as a little more squat than it really is.
