Unless someone posts a newer firmware for it.
It doesn't really matter anyway. The XL2730Z *AND* the Asus ROG Swift PG278Q have certain panel defects which cannot be fixed (while not all panels will fail, many users have had certain failures which happen on both monitors, and always the same symptoms. Even though the panel model number is different, it's the same exact panel, just a different part number to accommodate the different bezels between Benq and Asus). Also blur reduction is partially broken on the XL2730Z; the monitor will strobe at 120hz timings even at 100hz, causing an out of sync and unusable display. Also Vertical Total tweaks are IGNORED by the scaler, meaning crosstalk is not reduced whatsoever by increasing the vertical total. This issue (and the 100hz issue) was fixed on the XL2735 (you can tell by the scaler being different--Realtek 2796BF (same as on the XL2540) vs 2796B, even though (a personal pet peeve I have), the monitor will still double strobe at 60hz, making it worthless for consoles.

The problem is that no one has tested if FREESYNC works on the XL2735 or not. The scaler supports it, and in the monitortests CRU thread (and on Guru3d forums), people have gotten freesync to work on scalers which support "variable refresh rate" just by editing in the freesync range. But I can't find anyone who owns this monitor to test this (there's zero reason why it shouldn't work though).

Unlike the XL2540, blur reduction is enabled by default in the service menu (it's disabled by default on the XL2540), so you would have to disable "DyAc" and then try the freesync hack.

Does blur reduction work at 144hz or only 120hz? I'm about to buy this monitor for $380 refurbished and was hoping to at least be able to try blur reduction

Yes, MBR works at 144Hz and 120Hz but does not at 100Hz (strobes are not synchronized), and at 60Hz you'll get double-strobing.

Yes, MBR works at 144Hz and 120Hz but does not at 100Hz (strobes are not synchronized), and at 60Hz you'll get double-strobing.

P.S. On the XL2540, there are quirks similar to this -- 180Hz not working properly but 178Hz or 182Hz working well.

[edit -- moved to separate thread] Also, in regards to certain modes stopping working with certain refresh rates / certain Vertical Totals -- there's a new trick to help avoid that (Easier Testing & Discovery Of Large Vertical Totals) but this is not applicable to XL2730Z, I believe, due to its unsynchronized strobe pulses...

For XL2540, which has shown great flexibility (and even FreeSync compatible when hacked to 48-240Hz in ToastyX) -- experimentation will be needed to see what 'trips' up a specific monitor's scaler and/or 'trips' up strobe backlight synchronization (these can bug-out separately). This may or may not work, but it's worth keeping in mind.

For XL2730, which I have not tried, I'm aware its strobe synchronization does not seem to work as well as XL2540 does. Falkentyne has complained constantly about this issue.
