It is an acer XZ322QU. On overdrive normal it still has very bad ghosting and when I turn it on extreme it has some terrible inverse ghosting turning VRB on does absolutely nothing. tried putting it at cool color temperature didn't work, tried changing the gamma didn't work, tried lowering the refresh rate didn't work, and tried using free sync made it worse I've tried so many fixes and its pass its warranty I'm so lost, but I don't want to get rid of it cause my dad got it for my birthday seriously any suggestions or fixes possible please shoot it my way
