So let's say I have a PC that supports 144 Fps and I have 2 monitors one with 75hz and one with 144hz and let's say I want to play Fortnite now, it then makes 144fps or 75fps (I connect the pc to the two monitors)
One screen will show 144hz and the other 75hz.
Don't forget to activate the 144hz too.
Well it depends on the monitor on which it is started.
But of course you only benefit from this if your PC also manages 144fps.
And please connect the 144hz monitor with display port, and then set it to 144 Hz under display settings in Windows.
Not necessarily Displayport, DVI also supports 144hz, for example.
Displayport supports 1080p 144hz and I believe it will also be 144hz. In addition, DP is the best for gaming.
You can set 144 Hz on a monitor and make it primary. If fortnite then runs on this monitor. It also has 144 hz. The other one only goes up to 75hz. Therefore do everything important on the 144
One reads 144hz and the other reads 75hz. Depending on which one you're playing on, it's 144 or 75hz. But your PC must also be able to do this technically.
