 I am 'he"... :-) My name is Alex and I am so pleased to meet you!
Sorry for stealing your format of signature, but I wanted you to see my setup in case of replying or asking about it.
I know your directions are for Full RGB 60Hz desktop setup, but first there is no reason for me, because this is a HTPC only PC and I don't want it to change resolutions every time I start and stop a movie as all my movies and series are in 23.976Hz. Second, my setup PC->Pioneer->LG TV is struggling when changing resolutions. It takes more than 7, 8 or maybe 10 seconds to change format (HDR<->SDR or 2D<->3D) or refresh rates. 

 Howdy "he" err, Alex.  Nothing wrong with what you're doing especially if your OLED is struggling and you're not using HTPC as all in one.  You will introduce lag in KODI GUI though but if it doesn't bother you... 

Now with the new card (1050ti) and the latest drivers things are much much better. Don’t know if it is the combination or one of them. I really didn’t noticed any difference in lag or anything else between 60Hz and 23Hz in KODI GUI. But maybe that’s my eyes or the TV. 

 Lag.  Sluggish GUI when navigating like from title to title you will notice it's just not snappy.  GUI prefers 60Hz but doesn't mean it won't work.
