External monitor VG240Y locks at 30fps while playing games in fullscreen mode.

I just bought a new acer VG240Y M3 monitor which supports 180hz, firstly I cant see the option to set my refresh rate to 180hz in the display settings so I can only set it to 120hz. Second, when I play games (Eg: Valorant) on fullscreen mode the monitor locks to 30fps, it is only when I play it in fullscreen mode that my monitor does this, when I change it to fullscreen-windowed mode I get proper 120fps. The monitor switches on and off like its getting a new input and just locks to 30fps on fullscreen mode. Only while playing games on fullscreen mode I experience this issue, all the other times the monitor works like its supposed to. Can someone please help me regarding this?

Thanks

    Typically refresh rates are determined by your GPU, up to what the monitor supports. So if your GPU supports 120Hz only, you won't be able to get 180Hz even though the monitor supports that refresh rate.

    I understand that but my main problem is that when I connect my laptop to my monitor and open games on full-screen mode my monitor locks my fps to 30. Any idea on how to fix that?

    Make sure the full-screen mode is set to the correct monitor's native resolution. Any scaling resolution will have a reduced the refresh rate.

    @AnhEZ28 I did try setting it to the monitor's native resolution but for some reason as soon as I put it into fullscreen mode it turns off and turns on to only be locked at 30fps.

    What laptop you have? Do you have dual gpus? Like Intel and AMD? or only protcessor based integrated gpu?

    @Uz I have a Dell Inspiron 5590 and no I dont have a dedicated GPU, only integrated UHD graphics.

    IIRC that Dell has a 10th gen chipset and the DP port is 1.4b, so it should be able to handle higher refresh frequencies. Especially since you are at 1920x1080… Is there anything between the DP port on the Dell and the DP port on the monitor other than the video cable, like a dock, splitter or port adapter?

    @billsey No, I've connected the HDMI cable directly from my laptop to my monitor.

    Sorry, I meant HDMI 1.4b, which has the bandwidth for 1920x1080 at 120Hz or 3840x2160 at 30Hz. That doesn't support higher refresh rates than 120Hz though, so that is your limiting factor. You are going to need a new laptop with a newer GPU to support faster than 120Hz.
