Custom Resolution Utility (CRU)

I dont know if someone already answered this, but theres already 500+ pages so.

I recently just followed itsjerian's tutorial on how to get stretched res in Season 3 chapter 4. I downloaded the whole (CRU) Custom Resolution Utility application and did everything step by step. Right now I added a detailed resolution which was 1722x1070,240 Hz. But every time I opened up fortnite my monitor displays 1920x1080,100HZ. Even though my game is still monitor is still stretched to 1722x1070, but now its on 100hz. I'm confused on why its displaying at 100hz. I don't know if this is meant to happen, but the game is still playable. Just wanted to know if there's a way I can fix my the 100hz into the 240hz keeping the same stretched res without increasing input delay.
