How do I adjust virtual android resolution 320dpi vs 560dpi?

This is the layout i edit in my android studio,

when i launch my genymotion, i have this virtual tablet:

api 19 , 2560x1600 but 320dpi, I suspect the 3 layouts below don't match because of this xhdpi, 320dpi thing!

how do I change this? because I can't

always readjust it to look good in Studio and genymotion; basically the problem is what-I-see-is-not-what-i-get.
