Screen resolution changing automatically refresh rate limited to 50 Hz

Since I couldn't solve it, I'll post it.

So my computer is an MSI laptop (with 120 Hz screen), then I also have an MSI monitor where I play. My monitor is an Ultra Wide Full HD (3440 x 1440).

I don't have any type of issues ever, but just on EA games, Apex and FIFA 21 I find this limitation with the refresh rate.

So my monitor has 120 Hz, for example: CS:GO, overwatch, smite, paladins, etc. Have no issues running full screen. 

The thing is, even when my monitor supports up to 144 Hz, if I play at 3440 x 1440 with my computer it will run at 50 Hz.

That's why I changed to the native resolution to 1920x1080, so I can have this 120 Hz on my screen. Don't ask me why but, EA games like Apex or Fifa21, I click on my monitor settings (physical button) and I can see that they appear to launch at 3440x1440 and that means that it's only going to be on only 50 Hz and I lose 70 Hz (I'm really not used to playing a 50 refresh rate, it's laggy for me). I already checked video settings in-game, also Nvidia GeForce, say that's "1920x1080", but it's clearly on "3440x1440". If I go window mode it will change, but obviously losing too much on the time response and performance

I also tried checking from Nvidia control, but since a laptop seems like the feature doesn't appear. 

Does anyone have an idea on how to change the resolution on the Game files of Apex Legends?

Any suggestion is appreciated. I already contacted EA support, but... we literally did nothing.
