Hello,
There is SEVERE inverse-ghosting on my new Acer XF270HU when using Freesync via the display port. My GPU is an RTX 2060 XC.
I've read that this can be because of overdrive overshooting, so to speak. The issue I am having is described perfectly below:
Coronas / Inverse Ghosting

Coronas are trailing artifacts caused by response time acceleration (RTC, overdrive, ASUS Trace-Free, BENQ AMA). Pixels can overshoot their final color value before bouncing back, causing bright inverse ghosting. See TFTCentral Overdrive.
I've tried using different display port cables, updated my GPU drivers, but there doesn't seem to be a solution. This isn't a problem on my 75hz freesync monitor. Is there anyway to fix this? I notice this in every game I play, overwatch, fallen order, etc. I'll have to return the product otherwise, because the claim that ghosting and smearing are almost non-existent with this monitor is simply not true for me.
Also, I'm not sure if this is related, but there is a topic on this that is somewhat related, but it appears that overdrive is not turning on in some instances:
