Yes, all of the Benq Z series EXCEPT the XL2730Z will single strobe at 60hz, but you need to enable the single strobe option in the service menu. The XL2730Z has buggy firmware and will double strobe (at 120hz rates) at 60hz and strobe out of sync with stutters (100hz at 120hz rates) at 100hz
I would probably *highly* recommend the XL2720Z if you can afford it, because the XL2720Z has an extra AMA mode (only in version 4 firmware) that will lower the amount of overdrive artifacts you will get in blur reduction mode (it's an undocumented toggle, 1) enable MBR, 2) Go to AMA and set it to high, or move the slider to off/premium then back to high, or if its on high already, highlight it and press "back" instead of enter (pressing enter (button 3 on the OSD) will just act like a cancel).
This will recalibrate the AMA and set it to a much lower level, about 50% lower, equivalent to an 'AMA low' setting. To make most use of this will require a contrast setting of 0-15, otherwise the normal ghosting of black to white sharp transitions will be WAY too high. this benefits 2D sidescrollers the most. 3D games are not benefited very much, but 2D games (side scrolling/platformers) will see a big improvemenet but only if you drop the contrast after doing this.
With the default AMA high setting, black to white transitions are perfect (contrast 40-50) while light to dark transitions have a lot of "inverse overshoot ghosting". The AMA low undocumented setting removes all of that but black to white transitions will have high normal ghosting unless you drop the contrast to 0-15. (dropping contrast without toggling the AMA will just cause spectral white ghosting on black to white, which looks far worse).
The XL2411Z, XL2420Z and XL2430T do not have this toggle setting on their V4 firmware for some reason. This makes the XL2720z a MUCH better choice (v4 firmware only!!)
Hmm here's some pictures of what I'm referring to.
1) default AMA high settings on XL2411Z, XL2420Z, XL2430T and XL2720Z. Apparently the freesync XL2730Z also looks like this (this monitor can ONLY strobe correctly at 120 and 144hz--do NOT buy this for a console!!)
Contrast setting=43 (correct white point)
AMA=high without toggling, which is default calibration (1: set AMA TO high before enabling blur reduction, 2) enable blur reductionYou can see light to dark transitions show a lot of overshoot. Black to white (e.g. moving text on white backgrounds, poles/phone wires in FPS games) have no ghosting/overshoot at all. Dropping contrast in this mode causes black to white to turn into white spectral ghosting which is VERY ugly.
2) Contrast 43, AMA high after toggling on XL2720Z V4 (1) enable MBR, 2) move AMA to off/premium or back to high or highlight high and press "back" instead of enter = (AMA low). You can see inverse ghosting removed, normal ghosting added. Black to white with contrast 43 and AMA "low" toggle has very intense normal ghosting so contrast MUST be lowered.
3) Contrast 10, AMA "Low" Toggle, (reduced camera exposure to capture image better, its much brighter than this)
4) Contrast 0/10, ama low toggle with normal exposure, blurrier picture
**NOTE**
THIS TOGGLE IS UNDOCUMENTED in V4 XL2720Z ! If you change monitor OSD brightness, Strobe settings in the service menu (Duty, Phase or single strobe) or any refresh rate/resolution, the AMA will reset to default!!
