res=NearestResolution(screenNumber,[width,height,hz,pixelSize])
res=NearestResolution(screenNumber [,width][,height][,hz][,pixelSize][,outputId])
res=NearestResolution(screenNumber,desiredRes)

Finds the available screen resolution most similar (in log cartesian space) to that
requested. Any argument that is [] or NaN will be ignored in assessing similarity.
If you specify pixelSize then the returned res will specify pixelSize. Typically
you’ll use the returned “res” to set your screen’s resolution:

SetResolution(screenNumber, res)

Note: On Linux, if more than one video display output is connected to
a given screenNumber, you must specify the optional ‘outputId’ parameter
to select the output for which you want a match.
