Display Helper

Bug Description

Background info: I have a 4K 144 hz TV. For some reason in Windows there is not a profile for 1440p at 144 hz even though it is capable of it. I used CRU (Custom Resolution Utility) to add a 1440p/144 hz profile which I am able to successfully change to and use in Windows settings. I typically use 4K/144 hz on the desktop and would like to switch to 1440p/144 hz when starting a game with Display Helper.

Problem: When using Display Helper and selecting 1440p/144hz either in the global settings or per-game settings, Display Helper changes it to 1440p/119.88 hz instead of 1440p/144hz. It seems like this could be a bug when using CRU. For reference, I do not have this problem with other tools that can change the resolution/refresh rate (such as with Sunshine/Moonlight) with my CRU modification.
