LG 24MP59G problem setting refresh rate

[SebastianNG1]

Hello,

I own a 24MP59G monitor and have always wanted to have LFC which unfortunately it does not support.
I've been trying to follow this tutorial to lower my Freesync minimum refresh rate from 40 Hz to something like 35, (I've seen a few people post they can get 33-76 and they claim it makes LFC work on this exact model), however when following step 4 (create a custom resolution with your desired refresh rate on Radeon Settings, then apply the resolution in Windows settings) I get an Out of Range error on my monitor (no biggie, I understand that I just may have been unlucky and my particular monitor is not underclockable) however I tried to set a refresh rate to a value inside my Freesync range (40-75 Hz) and I still get the error, basically anything below 48 Hz will give me such errror, which I find weird because it is my understanding that I should be able to at least set it to 40 Hz since it is the advertised refresh rate for my monitor.

I'm using the HDMI cable that came with my monitor (which does support Freesync and is the same one that people that have got this to work report using), I do have a DP cable lying around but it's a piece of crap that can't even report 75 Hz on Windows when I connect it. I also tried both enabling and disabling Freesync, VSR, HDMI link assurance, etc.

I find this very weird, maybe I'm missing something, so any help would be greatly appreciated.
