The maximal value is 100 which suggests that the pulse onset can be arbitrarily chosen anywhere within the refresh cycle.

In MBR mode, also the pulse phase can be modified, in steps of approximately a 100th of the refresh cycle time, where a value of 0 makes the backlight pulse onset roughly coincide with the update of the first pixel line. The pulse width can be controlled either in 10 steps (LightBoost) or in 30 steps (MBR), linearly within the range given in the table. Tweaking the pulse parameters is especially useful if the LC panel update is accelerated by tweaking the monitor timing.ДЄs soon as strobed backlight is used, be it for LightBoost or for MBR, the backlight LED current is increased by a factor of about 1.8 in order to compensate, at least partly, for the time the LEDs are turned off between the pulses. This is possible either via the service menu (parameters strobe duty and strobe phase), or with BlurBuster's Strobe Utility, or via direct DDC/CI programming ( Display Data Channel/Command Interface). Besides letting the user activate MBR at frequencies other than 100 Hz and 120 Hz and without requiring specific NVIDIA graphics hardware, it is also possible to tweak the backlight pulse parameters, like the pulse width and the pulse phase with respect to VSync in great detail. On the other hand, BenQ offers more options regarding MBR, at least with firmware version v2. That is, LightBoost has the higher potential to get things right. In contrast to LightBoost, it does so without adopting a special LC panel update timing and without using different overdrive parameters for the different pixel lines, both of which should affect settling behavior negatively. Like LightBoost, MBR pulses the backlight once per refresh interval. Motion Blur Reduction ( MBR for short) is BenQ's alternative to 2D LightBoost. Note that, although the XL2411Z as almost identical to the XL2411T, upgrading a BenQ XL2411T with the Z-version firmware would not work (see below, Accessing the backlight signals). The results shown below have all been measured with version 2. As far as the flicker-free mode is concerned, there is no difference between firmware version 2 and 4 though. Currently (mid 2015), monitors are shipped with firmware version 4 which is said to implemented a better overdrive when Motion Blur Reduction is active.

See BlurBuster's firmware upgrade instructions for a step-by-step upgrade how-to. This brought BenQ to offer customers to send in such monitors for an upgrade or, as an alternative, allow enthusiasts to do the upgrade themselves (which, however, requires additional programming hardware). When these monitors were first released they came with a firmware that had a sub-optimal Motion Blur Reduction implementation. The 'menu' button will react normal again after the next power-on.ДЄs a first in computer monitor's industry, BenQ offers firmware upgrades for its Z-series monitors. Then you can push the 'menu' button to enter the OSD menu. In order to access the OSD menu, make the service menu disappear and then push any other but the 'menu' button so that the icons above the buttons appear. Pushing the 4th button from the left ('menu' button) will then toggle the service menu on and off. The service menu can be entered by keeping the 2nd button from the left ('down' button) pushed while powering on the monitor. Have the monitor connected to a valid signal source.
