Well, If you want this monitor ONLY because of the benq blur reduction, and not for the freesync capability, you're better off downgrading a bit to the XL2720Z. The XL2720Z with firmware V4 has much better blur reduction capability than the XL2730Z, despite it being only a 1080p panel. Someone above got the XL2730Z to work with the "AMA Low" setting, I think in this or the other xl2730z thread (this is a blur reduction toggle of AMA high) but then it didn't work anymore, he said; it's probably still available, but I don't have this monitor).
the XL2720Z however, with V4 firmware, has some big advantages over the XL2730Z if you can handle a 1080p 27" panel
1) AMA Low blur reduction (ONLY) toggle, enable MBR, then set AMA to high afterwards (or just highlight high and press back) recalibrates the AMA to low. Works best with a contrast lower than 15. This toggle (AMA low) did NOT exist in original release or V2 firmware. This was an undocumented 'feature' added.
2) Blur reduction capability from 60 hz to 129 hz in 1 hz increments, via custom resolutions, and single strobe option for 60hz-90hz, by enabling "Single strobe" in the service menu (this option is missing from XL2730Z).
3) Vertical total tweaks to improve the strobe crosstalk by changing the area the scaler works with for strobing (Changing the vertical total to 1502 (100hz and 125hz) or VT 1500 (@120hz; I found VT 1502 buggy at 120hz), can reduce strobe crosstalk by about 25%. VT tweaks don't lower strobe crosstalk on XL2730Z: see Bishi's tests in this thread:
XL2730Z strobe crosstalk at 120hz is equal to XL2720Z strobe crosstalk at 120hz without a VT Tweak.
(Note: XL2720Z running at a scaler downsampled resolution of 2560x1440--yes it can run at this resolution via an edid override and VT 1500 but only at 100hz) has identical strobe crosstalk as XL2730Z (at native 2560x1440).
