Thanks Brazen1, even without quotation I concluded that there was an answer to my question because 60Hz and not 23Hz , obviously trying I understood its usefulness I realized  and understood  that must be so , for not to be interested in a 3D automation but only for 4K content and SDR ,  how should I continue in the various steps for an ideal automation of your guide ?
utilization Kodi DSPlayer 17.6 and external Player MPC-BE 64Bit and PotPlayer , obviously with Windows 10 Fall Creators.

my playercorefactory :
