FORCEFULLY matching active signal resolution to desktop resolution

I have a monitor that natively goes to 4k@30 and I want to use it at 1440p@120 but windows keeps forcing the active signal resolution to 4k.

I have tried every single "fix" online, both from this forum and different websites, it´s been a known problem for YEARS and it bugs out both the TV itself and any app I try running on the resolution i actually want.

• Settings > Display > Advanced Display > Display adapter settings > List All Mode (Did absolutely nothing)
• Doing the same but going back to a 720p or other random resolution to try and force the active scaling to change (Did absolutely nothing)
• AMD adrenaline software disabling GPU scaling (Did absolutely nothing)
• Going into the registry and deleting every monitor configuration to force it to recognize again, it recognized as a 4k monitor and (Did absolutely nothing)
• Using the CRU to delete every other resolution and leaving only 1440p and reseting my monitor (Did absolutely nothing)
• Reseting monitor drivers (Did absolutely nothing)

I´m literally out of options, there are no more fixes online, other than switching to linux.
