Blur Busters Forums

As you can see in the video, namely @ 0:37, it is rather extreme.
Meaning, any FPS game (such as FPS cam in GTA V on PS4) means: Nope, motionsickness, eyes out of focus and excess blur meaning cant track enemies at all.. or anything really.. Objects such as Poles ghost into 3's or 4's and such.

Is there a solution to this? or a way to reduce it?

Do you have BENQ Blur Reduction enabled or disabled?
You need to tweak BENQ Blur Reduction first with Blur Busters Strobe Utility first (it works for calibrating blur reduction with consoles).

If you want to have crystal clear motion with consoles with BENQ Blur Reduction, you want:
1. BENQ Blur Reduction enabled
2. Tweak with a computer Blur Busters Strobe Utility (use 1920x1080 60Hz, no VT tweak) and calibrate until 60fps @ 60Hz looks good.
3. Now you can move your monitor to the gaming console (unplugging is OK. You don't need to keep the computer connected anymore.)
4. 60fps @ 60Hz console games. Not all console games can run at 60fps.

You should get much better motion with consoles this way. No more double-image effect (except faintly at top/bottom edge of screen).
That said, you will still have a problem with 30fps gaming consoles (it will still do double-image at 30fps).

Just saw that video.
You have single strobe set to off, which makes the monitor DOUBLE strobe at 75 hz or lower (actually I'm pretty sure 75hz is the cutoff because vertical total tweaks at 76 hz cause strange stuff to happen) but anyway, enabling the checkbox in the windows blur reduction utility automatically enables single strobe.

You can also enter the service menu by, with the monitor powered off, holding down the MENU button FIVE seconds, then while keeping it depressed, press the power on button, then you can release the menu button. (you can also hold down menu and press power on and release menu when the leds flash, but that's basically doing the 5 second press awkwardly (just hold menu 5 seconds then press the power on button). Then you can enter the service menu and enable single strobe, if you don't have access to a windows computer.

Basically, single strobe makes the monitor do normal single strobe patterns when it's using the 60 hz backlight pulse widths. Using vertical total tweaks (in windows) actually makes the higher refresh rates (100hz, 120hz, but NOT 144hz) use the 60 hz backlight pulse widths, so if single strobe is set to DISABLED when using vertical total tweaks, you'll get double strobing and the same judder.

You'll know you did it right because the screen will darken by quite a bit.

I think single strobe is disabled by default, because the backlight flickering at 60hz can cause problems for people who are sensitive to it (it's like a 60 hz crt..maybe worse).

If I enable Blur Reduction, the image flickers and I get fatigured after a few seconds.
I have already Tweaked it with the Tool.
Its plugged into PC via DVI-D and Console via HDMI, thus it should already run at 60Hz shouldnt it?

And GTA V runs at 30fps

@Falken.
I dont know why I would want Strobing enabled for 60fps and lower, insane flickering! :O


Single strobe is also enabled in Servicemenu "On"

Strobe Duty: 013
Strobe Phase: 000

Not everyone can handle single-strobe at 60Hz, but if you do use that, you need to view the monitor from a further distance, use more ambient lighting, and adjust the brightness. Also try raising persistence somewhat to about 3-4ms, to also compensate. A bright PC desktop at 60Hz strobe can be quite nasty, but slightly more distant viewing on slightly dimmer content with a little more ambient lighting, may be what works.

Some people really like 60Hz strobe backlight for console gaming, but not everyone does.

The best cure for this is to come to PC gaming, and get 120fps @ 120Hz, with clear motion, zero ghosting, zero blur. You may wish to turn off strobe and use AMA Off / AMI High and see how you like it (motion blurring might be the lesser of evil. It's a blurring-versus-flicker tradeoff).

You aren't going to eliminate the double-image effect in GTA IV during single-strobe, or quadruple-image effect during double-strobe. (Mathematically the number of duplications is stroberate/framerate ... So 120/30 = 4 images, and 60/30 = 2 images).

Already done that, wheres GTA V?
Gonna be full of cheaters on PC in multiplayer just like GTA IV, so no thanks.

My XL2420TE worked fine with my PS3 and GTA V on that, my XL2411Z got this crazy shit going on.. its like it cant handle 60hz and 30fps at all.

And no PC isnt the cure, zero ghosting zero blur? I got plenty of that..

As you may have seen on OCN.

So its either: Sell Monitor and buy something cheaper that does it better.
Or... play the PC version in February amongst cheaters! (And we dont even know if the game will run well on PC at all!)


Strange thing is also that... Dark Souls PTD (a 30fps game on PC) ran fine on my XL2420TE, but on my XL2411Z, I get this juddering.
Its like it cant handle 30fps AT ALL!

Changing AMA to Off removes the juddering ,but instead I get insane motionblur.

Strange! (assuming settings are the same).
This is strange since the image quality should be idential in non-LightBoost mode. I assume you're comparing XL2420TE (LightBoost disabled) to XL2411Z (BENQ Blur Reduction disabled), for an apples versus apples comparision? Also, I'm assuming you're not typically playing the monitor very cold (e.g. just turned on in an unheated cold room; as cold temps can cause more ghosting).

This be true, however, different strobed monitors at different settings will have variable amount of overdrive leftovers even during strobing, but there are some models where the ghosting falls to below perceptible levels when running refreshrate-framerate synchronized motion.

You can eliminate a lot of this on the BENQ XL Z-Series using the VT1502 trick combined with a lower refresh rate (e.g. 85Hz or 100Hz), to get an almost overdrive-free strobed image. Bigger the vertical total, the less overdrive will show up during refreshrate-framerate synchronized motion, with perfection in most real world apps, and much more faintly in solid-color motion tests (e.g. TestUFO). With the Z-Series, you ideally want to adjust your vertical total to reduce the ghosting.

If I enable Blur Reduction and turn off Single Strobe (yes OFF) the Flicker is gone completely (at 60hz) as if Blur Reduction is off.
Monitor does get dimmer.

If I enable single strobe again, flicker is back.

Does VT even apply to other hardware such as PS4? Is it a HW change or software change as its changed in Nvidias controlpanel rather than monitor.

No, warm room, and monitor has been on for hours.
Yes I compare them both LB off and BR off.

Ah, you're playing at 30 fps?
Ok, then you definitely don't want strobing on then. As if 60hz strobed flicker (60hz CRT) isn't bad enough, 60hz strobe with 30 FPS....no thanks. And with single strobe set to off, pretty sure you're going to get a quadruple image effect.

As Chief said, I'm really NOT sure why your XL2420TE looks fine on your PS4 with strobing off but the Z monitor looks bad. They're the exact same AU Optronics panel (AUO M240HW01 V8), same panel as the VG248QE. There are some HDMI color format options and display mode settings you can change but I don't see what can affect that. 30 FPS looks rather bad on a LCD anyway...in fact from the video you showed, if that's 30 FPS, that's how it's supposed to look, IMO.

Did you try changing the AMA settings? Maybe you have AMA off or set to premium, try a different setting. Also try instant mode on or off.

I had an LCD TV before, worked fine, slight blur but nothing as extreme as this.
It worked fine on these monitors so far (PS3 that is, 30 fps)

Looks horrible on the Z :/
