freesync shows not supported on a BENQ XL2730Z in the latest beta driver.
Display is hooked up with a DP cable and it worked prior to the Crimson drivers.
Same problem, Acer XR341CK here.
How To Enable AMD FreeSync™
This answer is not correct at all i did this it does not work crimson removed the option for me.
It sucks to have a 700$ monitor and its main feature does not work just because of some stupid driver issue.
Please report the issue here.
I did this not sure if it has enough data for you guys but i hope it has.
Edit: Tested the latest driver just now still shows not supported.
