How to save high resolution plots without displaying it on the screen?

I haven't found solution to use retina display with MATLAB, because the highest figure window size in pixels is far smaller than the retina resolution. I think this cannot be solved, this disadvantage of MATLAB at the moment. However without displaying the plot on the screen, is it possible somehow to save it? In case of putting a larger plot on the screen and using saveas, the saved picture file shows only part of the plot, so this is not a solution. Or is it possible to modify plot or saveas with proper options to handle this?
