How can I change the default command window resolution?

My screen has a resolution of 3200 x 1800. However matlab only recognizes a res of 1600 x 900. This causes all of matlab (command window, figures, everything) to only use 1/4th of my screen making it impossible to read. Is there a way to force matlab to recognize my screen resolution? I tried:

>> get(0,'screensize')

ans= 1 901 1800 900

>> set(0,'screensize',[1 901 3200 1800])

Error using set
