Hello my friend again

I can tell you i´m not familiar with this tool, what i did was run CRU, saw what was in the detailed resolutions, and there was only something like the picture attached (ATTENTION THIS IS NOT MY PICTURE, i´m not at home right now, i just download it from google to explain you this better, latter i can post the real one), where instead of saying 60HZ only says 59Hz, the other options (120Hz, 144Hz) didn´t show up.
So i edit that option and put 60Hz and add the others 120Hz and 144Hz, clicked on OK, and close the program, then i try some games, all of them gave me the same result, no changes

In the standard resolutions it was empty like the picture

And in the Extensions Blocks, show something like that, but regarding the Displayport 1.2 that i have connected

After tested all this, i go to Detail resolution again, and delete everything. Now everything is blank on that square

I didn´t notice any changes, everything is the same, but as i told you, i´m not familiar with the tool, and didn´t find a deep tutorial about the tool, only things like "change this and that".........what i have done, but without any results at first sight
