Thanks greatly. Hopefully this will help some people get more out of their Z series monitors.
The XL2720Z is still my primary monitor to this day. And being able to make the overdrive setting close to "Perfect" (equal approximately to Asus Tracefree=60 on their older VG248QE/VG278H) when blur reduction is disabled is something hardly any other monitor can do.

Updated with comparison pictures of what AMA low mode does to improve the monitor (Based on XL2720Z V3-V5 firmware. XL2420Z, XL2430T, XL2411Z will have improvements, but much less (basically, minor improvements rather than major improvements). V2 will make the AMA twice as bad so V2 cannot be used.

Blur reduction on, AMA high, default (This was taken at 120hz, strobe duty 009, contrast 43 (1.5ms persistence with VT tweak) with strobe phase at 000.

Blur reduction on, AMA low, contrast 43 (don't remember the refresh rate but it is irrelevant--this is how it looks).

You can VISIBLY see the difference massively. All inverse ghosting has bee reduced to the point of normal ghosting. While this is a 'big' swing in the opposite way from a perfect calibration, sometimes on 2D side scrolling games it helps. Sometimes the minor XL2420Z/XL2411Z boost is better. You can improve this on the XL2720Z even more by dropping contrast from 43 to 10.

120hz, AMA low, contrast 10, Strobe duty 009, camera exposure time -2.0 to make moving images clearer (that's why the screen is so dark, NOT the contrast 10, although lowering contrast does make things more washed out and has an effect on brightness in a way, but not on the backlight directly).

The BENEFIT of the XL2720Z "overshooting" the AMA low so much is a HUGE benefit to blur reduction OFF, by using the bug in the first post with profile switching. This is because, blur reduction off's AMA high is basically the same as blur reduction on's AMA premium! So the 'AMA low" is shifted heavily towards the right if you do this, making blur reduction off's AMA not show hardly ANY ghosting whatsoever--ZERO inverse ghosting and barely zero normal ghosting!

The XL2420Z, XL2411Z, 30T etc would all show inverse ghosting, but obviously less, but not much less.

Here is 100hz:
100hz, blur reduction OFF, AMA high.

Whoever is in charge of overdrive at BenQ is not getting paid enough. Aluminium stands put a dent in the paycheck. BenQ's overdrive implementation is legendarily bad and with all the attention they're getting from gamers recently, you'd figure they'd pay more attention to this. Especially since they're industry leaders at strobing.

So they have only one model with good overdrive and it's a hidden feature. It's like they don't want to improve this. Maybe someone's dog had enough and sneaked into the factory to put that firmware in there and it was too late to recall when they realized.

In all seriousness though, it's easy to forget that these are cheap consumer electronics and not professional gear that is manufactured with utmost care and attention to detail. That's simply how it is with gaming. Engineers won't be paid extra for improving overdrive that a only a handful of enthusiasts somewhere online care about.

Just read the whole thing, amazing really , like everyone on here already said (and those who didnt - surely thought about it) . Thank you very much , this helps a ton.

The TF="50" like bug on the 2720z is also pretty great.


Thank you again :)


EDIT: If using one of the MBR=OFF AMA tricks so I shouldnt go custom res + VT (over DVI if it matters) right?

XL2735 VT tweak info added. VT Tweaks up to 1825 are working with this new screen ! (144hz is limited to 1562 or around there).

So, whats actually going on with the tweaks? They spit out the pixels sooner and quicker?

Can you measure how fast they are getting spit out?
