Lightboost and Benq blur reduction are not the same thing.
Although your monitor DOES support Lightboost, it's part of 3d vision 2 and requires an Nvidia video card to unlock it. The Strobelight method of using Lightboost on AMD video cards does NOT work on this monitor because the 'bypass' that strobelight used was patched in the Benq firmware.
it works on the previous "T" series (NOT the XL2430T) Benq monitors, the Asus VG248QE, and an Acer model that has lightboost permanently unlocked so only the Lightboost custom Vertical Total values are needed to use it.
You have Benq blur reduction to use instead of Lightboost. Benq's blur reduction actually uses some of the Lightboost hardware (since it's already in the panel) but allows far more adjustments.
You can read about the difference between lightboost and BBR here.http://www.tftcentral.co.uk/articles/motion_blur.htm
As far as settings, well that's up to you. I can't tell you how to use your monitor. Everything about the "1 frame of higher input lag" compared to the "no added input lag BUT more strobe crosstalk" is in this thread. viewtopic.php?f=13&t=2590
I wrote everything down so I'm not going to copy everything I wrote all over again. its here if you take the time to read and understand it.
Yes it's complicated. Because a lot of the stuff that "improves" the monitor from its CRAPPY default settings (mainly the horrible AMA high default setting) and the crosstalk issue, is from exploiting firmware bugs. And exploiting bugs is NEVER "quick and easy" until you know what you're doing. Thankfully once you understand it, it's simple. Just annoying to do.
The best thing to do when you get the monitor is to actually experiment with the settings, while looking at the values and features and tables shown and see how they change and work for you in person.
A lot of people just want everything quick and easy as if they're playing a console. The "quick and easy" settings for the XL2411Z are to set Strobe Phase 000 and keep it there, turn on "single strobe" (service menu option) and then adjust the Strobe Duty to balance brightness vs more blur reduction (You can do all of that with the windows utility with a Vertical Total tweak active (note: use VT 1500 for 120hz and VT 1500 or VT 1502 for 100hz. I found that VT 1502 at 120hz can be unstable sometimes randomly).
Basic "have fun and play fast" settings for blur reduction are usually something like:
Brightness: 100 (REDUCE THIS if NOT using blur reduction)
RGB Values, custom whatever, usually 100, 100, something. Lower blue channel from 100 if you don't like blue.
100hz or 120hz refresh rate with a Vertical total tweak (VT 1500 is best).
If NOT using blur reduction, the monitor looks rather bad unless you do the AMA toggle to lower the AMA via a bug. The default AMA high setting is just garbage. I explained that in the thread I made. The XL2720Z benefits the most from the AMA toggle bug. But the XL2411Z still sees a -massive- reduction in purple trails when doing this.
I don't recommend blur reduction at 144hz ; crosstalk covers a large part of the screen AND VT tweaks (to lower Crosstalk amount) do not work past 128 hz (129hz with a VT is unstable).
Pretty much everything else, including if you want to lower input lag by ONE FRAME and so on, is here.viewtopic.php?f=13&t=2590
The one thing that annoys me the most is when CS:Go players start bugging me for settings for CS:Go. I don't even PLAY that game.
Pick whatever looks better for you and just use it. Whatever happened to people experimenting for themselves?
