No hidpi help plz

Installed Switchresx e followed the guide to add scaled resolution for my display. I still cant use a 1080x720 in hidpi for example. Native res work well! But if i try other hidpi res, they will not work. Ill see blurry. How can i fix? I have a Samsung Galaxy Book 12 with Osx High Sierra, Switchresx installed
