Is freesync working?

[Karizma]

I purchased this monitor to use with my rx 580 to try freesync, now I tried it out in a few games and it seems like its not working.  I assumed it would cap my fps at 75 as thats the hertz of the monitor but I was still over 100 fps and seeing screen tearing.  It's in fullscreen and I have it enabled in radeon settings, I'm not sure what else I'm missing.

 

Now I have it hooked up with a hdmi which its compatible with but the only thing I can think of is if I needed a new version HDMI since this is a old one from a cable company I had.  I also tried using FRTC and limited my fps to 72 and after I did that I had no screen tearing and vsync wasnt on, Does that mean free sync is actually working and the hdmi is fine?

 

Sorry if this sounds scattered brained I just dont know what the fuck I'm doing.

Freesync only works when frame rates are below the monitor's refresh rate and it only controls the monitor's refresh sequence according to frame rates. without touching frame rates themselves. Try a demanding game and crank up the settings as high as possible so frame rates drop below 75, then you'll see Freesync doing its job

FreeSync only operates when your framerate is below the refresh rate of the monitor. When your computer can produce higher framerates, the behavior depends on your V-Sync setting. If V-Sync is on, then your framerate will not go beyond the monitor's refresh rate. If V-Sync is off, then your framerate will be allowed to pass above, and you will get tearing when your framerate is above the monitor's refresh rate.
