75hz monitor & games weirdness

Hello, monitor noob here.

 

I have a ViewSonic VX2457-mhd 24" 1080p monitor. The specs for this monitor state that it has a HDMI input signal of 47 ~ 75hz, which I think means that this monitor can output 75 fps over HDMI.

 

This is reflected in certain games like Dying Light and Sinner Sacrifice for Redemption that automatically set the refresh rate to 75 fps when I turn on v-sync.

 

However, a number of other games (Quake Champions, Killing Floor 2, and World War 3) set the game on 60fps with vsync. Overwatch is even weirder - it sets the vsync on 60, but the display based framerate option sets to 85 in-game (which happens to be at 83hz which is what the VGA input gives, even though my monitor is connected via HDMI).

 

On the other hand, when I turn off vsync for Quake and Overwatch and manually set the framerate to 75fps max, it runs fine with no screen tearing that I can see. 

 

So what the hell is going on with my monitor and games? Why does the vsync for some games treat it like a 75fps monitor, and the other goes 60? :]

first of all i don't think that there is a support for vsync t 75fps , there is at 60hz 120hz 144hz + 240hz , i pretty sur that the native hz of your monitor is 60hz as the majority of other monitors

Yeah, I thought 60 was native too. 

 

But then why do some games set vsync framerate to 75fps? :P

What refresh rate is the monitor set at in Windows?

 

EDIT: in case you don't know how to check

Quote

Right-click desktop -> select Display Settings -> select desired monitor -> select Advanced display settings -> select Display adapter properties -> select the Monitor tab -> Make sure it says your desired screen refresh rate under Screen refresh rate.

Btw input signal frequency does not equal refresh rate. But the VX2457 is 75hz.

Thanks for the explanation on how to set it. It indeed offers me 75hz in the monitor properties, so I set it. We'll see if I get any screen tearing now.
