I'm noticing inverse ghosting ("trail left by the UFO") but no ghosting by itself

Try to look for overshoot artifacts, if it's got ghosting and blur, overdrive is disabled. If it's got at least a tiny amount of overshoot, then it's enabled and on the normal preset, but I did looked for it on my Acer and was nowhere to be found

I asked about this internally and I've been informed that Overdrive has been optimized within Freesync, which is used with the Displayport. Therefore, the OSD option has been greyed out since it is enabled with Freesync.



I hope this helps,
Cory

Yes that's how its SUPPOSED to be.
The PROBLEM IS, EVEN IF FREESYNC IS DISABLED, overdrive becomes disabled as soon as the monitor enters native resolution--EVEN IF FREESYNC IS OFF.

Someone needs to tell these dumb as rock Acer parrots this.

I probably should have included this. Compare what you see as best you can to this picture:

http://www.tftcentral.co.uk/images/asus_mg279q/pursuit_camera_2.jpg

Both of those are the ASUS MG279Q, left is at 120 Hz right at 144 Hz. What does the trail look like?

Well I'm not an expert at all but the trail looks more like the one on the right, although more pronounced(longer/wider). the rest isn't blurry though. basically everything on the right of the UFO/the UFO itself is very clean and there's just the trail at the left that's noticeable.

New info about the problem:


"erbury1983,
Sorry if I was not clear. Overdrive is 'tuned' with Freesync enabled on the Displayport. This is the reason Overdrive is not configurable in the OSD. It's already working.
Freesync does not work through HDMI, therefor Overdrive can be enabled/disabled with HDMI.

Cory"

So it's like those pictures, but much blurrier? The streak is normal in color but just blurry, like something moving really fast?
