VM Screen Resolution

Hi everybody, i need your help for this issue, perhaps i don't know if it is. The problem is that i can not get increase the screen resolution in a windows 2012 virtual machine more than 1024 x 768. There is no option for more resolution than 800x600 to 1024x768. I have installed other VM like windows 7 and they have more options for screen resolution, from 800x600 to 2560x1600.

Is ther a problem with my installation or is the maximum resolution for that O. S. in VM install.

Thanks in advance.
