Alienware AW2518HF - Is this behaviour normal?

Postby Shrib » 27 Apr 2019, 11:35

Hi,
I'm having some strange issues with my monitor.

I could have sworn that my FreeSync refresh rate counter would change according to the current fps. However now it seems to fluctuate all over the place including over that of the current fps (to 240 when capped at 200 fps for instance). Furthermore, the Overdrive 'response time' setting in the OSD does nothing, there is literally no difference between any of the modes. I've verified this across multiple OS installs with different CRU setups.


https://drive.google.com/file/d/1KO-2cL ... q7mLd/view (at 0.16 I cap the fps to 200)

This is at completely stock settings.


If I remove the display's identifying information using CRU (to render freesync unsupported) then my overdrive settings work again but it's not using the superior calibration that the FreeSync mode provides. Tried different cables, different DP slots.

Input welcome! Thanks

EDIT: Supposedly this fixed FreeSync overdrive mode is normal but I didn't think it looked good in motion, there is overshoot!

FreeSync doesn't keep steady Hz even if the fps are.

About the overdrive:

I think this is the same thing I mention, not an issue, just how it works.
Maybe Jorimt or Chief know something.
