The S Switch doesn't work properly
and if you want Blur Reduction you have to do the 120Hz change?
-- S-Switch had bugs in earlier firmwares on some BenQ/Zowies, but many have been fixed.
-- You can do Blur Reduction at any refresh rate on some BenQ/Zowie models (strobe crosstalk does get worse the closer you reach maximum refresh). The 120Hz Blur Reduction limitation only applies to ULMB and to some earlier Zowies.
For Brighter Blur Reduction
XL2430 doesn't have bright Blur Reduction. This is something that must be carefully chosen at purchase-time. If you want super-bright Blur Reduction on a BenQ/Zowie, you need to use DyAc. The "Dynamic Acceleration" models have extra-bright Blur Reduction that's not too much dimmer than non-strobed. Models such as the Zowie XL2546 240Hz monitors can do it. Also, newer ULMB on some GSYNC monitors are also extra-bright (not all models, though).
As a general rule of thumb, currently if brightness is important during blur reduction -- then 240Hz ULMB and 240Hz DyAc are currently the industry's brightest Motion Blur Reduction strobe-backlights (even when run at 120Hz or 144Hz). That's why, nowadays, I recommend that ULMB/LightBoost enthusiast consider getting a 240Hz ULMB or DyAc monitor -- they do 300 nits in strobed mode which is about ~3x brighter than yesterday's older LightBoost motion blur reduction technology.
Some 144Hz monitors do blur reduction quite brightly (especially the 144Hz DyAc monitor, and certain recent GSYNC monitors) but blur reduction brightness has become much more consistently bright with the newer 240Hz monitors if you want the "brightest and most colorful LightBoost-like mode".
No, it's a technological limitation for high-quality blur reductionQuaos wrote:It seems people would rather have Blur Reduction on at 120Hz than run without at 144Hz?
While blur reduction can work at maximum Hertz, it has a side effect called strobe crosstalk. Blur reduction works better at a refresh rate slightly lower than monitor's maximum. This is because of strobe crosstalk (advanced technical explanation). Technologically, a Blur Reduction strobe backlight need to "cram LCD GtG response between refresh cycles in Vertical Blanking Interval". The easiest way for a monitor to do that is to use a lower refresh rate to create a longer pause between maximum-scanout-velocity refresh cycles. This produces enough time for LCD to refresh in total darkness before a strobe-backlight is flashed once per refresh cycle (for Motion Blur Reduction). That's how Motion Blur Reduction works on modern gaming monitors (whether LightBoost, ULMB, BenQ, DyAc, etc).
Examples of strobe crosstalk double-images during Blur Reduction
Bad strobe crosstalk
Average/common strobe crosstalk
The closer you strobe to a monitor's maximum Hz, the closer to "Bad strobe crosstalk" (especially at top/bottom edges of screen) becomes. A good crosstalk motion test pattern is http://www.testufo.com/crosstalk -- you will typically have a band of "closer to bad strobe crosstalk" at top/bottom and "closer to average crosstalk" at screen middle. (With properly adjusted strobe phase, at least)
The more headroom margin your refresh rate has (e.g. 120Hz ULMB/DyAc/MBR on a 144Hz monitor -- or doing 144Hz ULMB/DyAc on 240Hz monitor) the less crosstalk there is during blur reduction modes.
