Answer 1

Modern monitors eg LCDs have fixed physical resolutions so when they get a signal in a resolution other than their native resolution they have dedicated hardware that interpolate the signal into the physical resolution of the monitor, some better than others. That’s why a display usually looks best at its true resolution – although it can cause geometry errors as physical pixels are often not perfectly square
