I have a Huawei Mateview GT 34” Ultrawide monitor which has a range of 48hz-165hz
I’m getting 65fps in game and the only way I can stop screen tearing is by turning on the in game V-Sync.
The monitor has Freesync Premium built in but doesn’t seem to do anything regardless on whether it’s on or off.
I’m wondering why I get screen tearing even though the in game fps is within the monitors range of 48hz-165hz. I thought that you would see issues if the fps drops below the monitors range. Why is this? Would a monitor with true G Sync with a module built in solve this?
As I understand it if you have nvidia card this will only work over displayport not hdmi. Hope this helps.
I am using a Display Port cable so not sure why it doesn’t seem to be doing anything. I’ve tried all different ways but only the in game V Sync seems to sort the problem out. Even then there still seems to be ghosting.
I have a new FreeSync monitor being delivered tomorrow. If I can shed any further light on the subject I’ll get back to you.
ähmm… also “on” in monitors osd menu ? 
Artifacts can also happen below the “normal” frequency. For that dynamic sync is g-/freesync just made.
In generall,… if its work fine with v-sync on, then set it to on 
… V-sync just works if FreeSync is out of range. I also not exact sure about the new FreeSync “standarts”, but I thought the monitor doubles the frequency if you come in the lower ranges ( where normal freesync will not work )… think they call it LFC feature. And that can have may again a effect.
And dont set vsync in nvidia control panel, or also not adaptive, fast, etc… stuff …
Got my LG 4k monitor delivered. I had to go into LG software and enable FreeSync, it was disabled by default. Then into Nvidia control panel, 3d settings and enable G sync. It may say your monitor isn’t supported but tick the box anyway. All the best.
