Good Morning,

I'm considering replacing my current monitor with the BenQ XL2411Z 24" and have been reading various reviews.

I stumbled across one that mentions "Strobe Crosstalk" on Z series monitors with V1 of the firmware.

Has anyone experienced this, and what version of the firmware is on the ones currently shipped by OCUK?

Looking around I'm actually tempted to possibly go with the Iiyama Prolite GB2773HS-GB1 144Hz, especially when it's only £10 more.

From the reviews it looks very promising.

Thoughts anyone?

I am in the same boat. Does the Iiyama have any blur reduction tech that the BenQ has? Does it even matter? I feel like I'm being brainwashed by marketing tricks :p

Also, what's different about the BenQ XL##20Z series, in comparison to the 2411Z?
 
no blur reduction feature on the Iiyama, or NVIDIA 3D vision support....also missing all the gaming extras which are actually pretty good on the BenQ like the S-switch, Black eQualizer, massive range of aspect ratio options. The BenQ is a better overall screen i think personally. And yes, the blur reduction feature really does make a difference to overall gaming and motion blur perception :)
 
OK thanks. I'm tempted to wait for the V2 firmware version of the 2720Z because people on the blurbuster forums say it can bring improvements and I don't really fancy faffing with getting it upgraded myself. Annoyingly if I hadn't read about it I probably wouldn't have noticed :p

You have any idea when you may be getting the monitors with V2 firmware in stock?

Honestly, it's not something most normal users should worry about. Read TFT Central's take on it and also my XL2420Z review. If you still have doubts then type 'What is the next step up from an ASUS VG248QE for gaming?' into Google.

I read your review - very informative, thanks. My concerns are now put to rest. I think the XL2420Z may be my next monitor!
 
Isn't there a benefit having V2 f/w only if you use Blur Busters Strobe Utility for BENQ Z-Series?

Having recently used LB for 2D gaming I would go with a side of caution as your colour's will take a massive hit and look washed out and dull in comparison.

There is no doubt in my mind that it delivers what it says:

1. Make BENQ Blur Reduction brighter
2. Make BENQ Blur Reduction clearer with sharper-looking motion (CRT-clarity)
3. Improve double-image artifact during fast horizontal motion in bottom half of display.
4. Adjust for trade-off of reduced input lag versus reduced ghosting.
5. Make 60Hz strobe work for PC/Mac games, for consoles, and for sports video.

imo it's not worth sacrificing vivid colour over. It will be interesting to see how the ULMB in the PG278Q deals with this, if at all.
 
The blur reduction feature on the Z series doesn't mess up colours or brightness in the same way as LightBoost methods do. See our teste here for more info

http://www.tftcentral.co.uk/reviews/benq_xl2720z.htm

The Blurbuster utility only allows you to change 2 things. the timing of the strobe, which helps "move" where cross talk ghosting appears on the screen and the length of time for the "off" period of the strobe. The latter option does decrease brightness but can bring some minor improvements in perceived Blur if you want to play around with it

Again explained in more detail in the above link. The blur reduction mode is overall easier and better than lightboost imo

When you turn Blur Reduction on you are left with a fairly similar setup thankfully, and there isn't any major impact to the image other than the reduced luminance. When we'd tested LightBoost we'd seen a fairly big impact to the white point but that was not a problem here with the natively supported Blur Reduction mode. The white point has strayed slightly from the calibrated 6505k point, now being slightly cooler at 6608k and leaving a 2% deviance. Gamma and colour accuracy remain very comparable to before although there is a slightly higher dE in the blue shades now. The luminance has dropped from 119 cd/m2 to 71 cd/m2 now though which we know is the main difference when enabling Blur Reduction.

Not bad. :)
 
I did make a post some time back on here about this monitor ,I all so got in contact with overclockers about the monitors they have in stock as to if they have the latest firmware ,They said they don't have V2.0 firmware as far as they knew .I all got in contact with BenQ UK/EU to see if they could tel me where i could get one that was all ready done ,

There reply was this

Thank you for contacting BenQ.

All the monitor manufactured after mid march 2014 will have the new firmware version installed.
Since all the shops obtain their stock from distributors, BenQ unfortunately does not have any chance to track where a single unit or a batch goes, therefore we cannot provide an information on where to purcahse the latest manufactured monitors.
Please be informed that the version 2.0 of the firmware does not add any improvement to the version 1.0.
It only allow customer to use a third party software to have more settings under the blur motion reduction.
If you need to have an upgrade, we cannot offer you under full warranty conditions, but we are willing to perform the upgrade free of charge. The only cost you need to bear is the shipment of the unit to our service partner RepairTech.


Kind Regards,

Ugo Turcio

BenQ Europe



So for me I'm still trying to hunt one down with know luck .

I am getting very consistent Version 2 reports from several vendors so based on this new consistency, I would think that by now, monitors on overclockers.co.uk will now be shipping V2. So hopefully, it should be safe to order from this site by now.

There are hundreds of people who are very picky about the artifact issue on V1, so this was a very important development (even if a thousand other people may not notice). but Version 2 satisfies both audiences. There is also now a new hardwareless method of upgrading Z-series (using Linux) from V1 to V2, now published in Blur Busters Forums.

Also, some of those in Blur Busters Forums have newly found a way to do the VT1500 tweak (combined with using ToastyX Pixel Clock patcher to raise the dotclock limit), which creates a ~3ms-long blanking interval pause between refresh cycles to let GtG transitions settle -- 1080 visible scanlines and 420 blanking interval scanlines -- eliminating even more of the strobe crosstalk between the refresh cycles (caused by incomplete GtG pixel transitions leaking between refresh cycles).
