2560x1080p75 on 25UM58-p

So my monitor (lg 25UM58-p) has 75hertz but in nvidia panel it only shows 75hz on lower resolutions. My question is will my monitor break if i change it to custom resolution 2560x1080 with 75hz?
Also my graphics card has hdmi 1.4
I already changed it to 75hz and its pretty smooth but I am worried about my 180$ monitor

It is a 75 Hz monitor so it shouldn't break from doing what it was made to do.
