Some informative posts about quality, good/bad models, etc. Started as a whining on 2411Z model

And also some conspiracy included.

Hello, guys!
Just bought this monitor, 144Hz feels absolutely awesome, compared to 60Hz.
But I have 2 questions about this monitor:
1) I noticed this dark spot ~0.5cm in diameter. It's only noticeable on black/gray colors.

Is it bad (it's unnoticeable overall)? I still have a few days to get moneyback.

2) There are strange deadpixels that appears at 120/144Hz (everything fine on 60Hz):

Tried other DVI cable (that comes with monitor) and they're gone now.. cable can cause that?

 

[Falkentyne]

Yep a bad cable can cause all sorts of things to happen.
Are you sure its completely fixed?

 

[nightmaster47]

About "dead" pixels yea. This was because of cheap chinese cable.
But this spot is not cable-related, It's noticeable even with unplugged cable.

Dark spot is still there and it has no relation to cables/signal. By the way it seems that there are not just spot, there are kinda dark pattern:

 

[Falkentyne]

If that spot is annoying, you should consider an RMA. It looks distracting.

I don't know if this model is so bad, but mine BenQ was extremely awful.
Why? Because I swapped it for PHILIPS 242G5DJEB (24/144) and OMG in terms of image quality its totally AWESOME in comparison to BenQ.
So it seems realy like a bunch of defects of BenQ's matrix. No dead pixels but.. it's extremely bad, in many terms(grayscale, colors, dakrer areas, this dark spot..).
Also I found that colors in different areas of BenQ differs a bit. It's slightly noticeable but... It 's really annoying.

So, now I have PHILIPS 242G5DJEB. But do you think I'm happy? NO.

1) Build quality is really bad. It's like 4/10. I will post some images later.
2) Again on build quality: it's hard to set this monitor exactly horisontal, because of shaky stand.
3) Plastic is worse (thinner and overall quality) than BenQ's.
4) Not so adjustable (settings) like BenQ.
5) ??? Maybe it doesn't have any kind of blur reduction.??? It was an awesome option on BenQ.
6) Remote control also has awful build quality, 2 buttons doesn't click (it works but.. feels spongy).

So, overall PHILIPS has really good image quality, 4 usb ports hub and.. many cons.

I just want a 144hz monitor.. 2016 year on Earth and I can't just buy it and be happy

Next try????
Another BenQ XL2411Z (maybe mine was defective?)
Or maybe some similar ASUS, AOC, or??????

I would get another benq, I had a 2411z and loved it, probably going back to a 144hz display again since 60hz is so ridiculously crap its unbelivable, everything I play it lags so bad response time is abysmal, I can live with a non IPS if i have to, but most likely gonna set some money aside and buy a 144hz IPS panel, the problem being to run 144hz @ 2560x1440 you really need a beefy GPU perhaps two.

 

[nightmaster47]

Some guy from ESReality said that he has exactly the same defects with his BenQ.
We need to find out more info on BenQ's, because if this is kinda "normal" for BenQ's then I think we even cannot call it a monitor

It's a desk with backlight, not a monitor

What about image quality? Do you noticed any problems with your 2411z or not?

I got moneyback for BenQ and bought PHILIPS... Now I think I'll do a moneyback for PHILIPS and... don't know what to do next(I think guys in that shop will hate me if I'll do some more moneybacks XD, but wait.. I dont't want to pay for $|-|1T).
Why?
Because all cons of PHILIPS is really a reason to do that.
I know one thing now YOU CANT TRUST TO ANY KIND OF REVIEWS, because they are likely LYING that telling truth, and also you don't need to be an expert to test your monitor. You need just 2 eyes and "ScreenTest.zip" (Ill upload it later, just .png images with grayscales, test pics).
144Hz is like drugs and now I can't play games without it

Neeeeed a good 144Hz monitoooor...

About ghosting on PHILIPS, YES it's here. Really noticeable, like on BenQ w/o blur reduction. I will test PHILIPS today, set up software and look for some settings, maybe there are some settings for blur reduction.
Also PHILIPS has 2ms input lag? But I don't think it's matters, because BenQ has up to 5ms, depends on your blur reduction settings. 1ms is unuseable, too dark.

Maybe ASUS is better? AOC(as far as I know it's has the same matrix as PHILIPS, and no blur reduciton)?

Well.. we need BenQs build quality and PHILIPS matrix + blur reduciton to have a decend monitor

XL2411Z http://www.digitalversus.com/lcd-monitor/xl2411z-p17975/test.html
vs
XL2411T(previous revision of the same model) http://www.digitalversus.com/lcd-monitor/benq-xl2411t-p15802/test.html

THEY ARE THE SAME. For some reason 2411Z has 2/5 color quality, and has a big chance of getting artifacts like this dark patterns/dark spots.

ALSO ON 144Hz Monitors.
To choose the good one is really difficult.
Many of them doesn't have any kind of blur reduction, some of them have high input lag, others have really bad build quality and bad image quality (colors/contrast).

OVERALL CONS(pros) OF ALL ~200-380eur 144Hz monitors
ASUS - blur reduction doesn't work with 144Hz (only with 120Hz).
PHILIPS - really bad build quality, bad response time, ghosting. no blur reduction.
BenQ - overall one of the best brands but.. there are fails like 2411Z. BenQ might be the winner in:
-Build quality
-Responsiveness
-Adjustability
-Blur reduction (works on 144Hz)

The only bad thing may be contrast ratio (less than 800:1) and color accuracy (at the moment there are only one really bad model - 2411Z others are fine and like at least 4/5).

Good monitors are: 2411T, 2420G, 2430T, 2720Z (really awesome), (and maybe 2730Z is good+).
Iiyama - averagely ~3/5 colors/contrast quality. Some models are good. Build quality like 3-3.5/5. Has a blur reduction called overdrive.
AOC - well, most models has bad colors/contrast. And no blur reducton.

SO, OVERALL:
Try BenQ 2411T, 2420G, 2430T, 2720Z. Don't know about other models, but these must be good.
Link to test: http://www3.zippyshare.com/v/KWwJrvYo/file.html

We need to find out which panels are in concrete models. Because there may be some lying from monitor producing brands.

Only thing I've found is http://www.tftcentral.co.uk/panelsearch.htm
But it has no concrete data on some monitors:
2411Z: 1ms G2G + 144Hz [24"WS AU Optronics TN Film (M240HW01 V8)]
Other data are not full:
2420G: 1ms G2G + 144Hz [24"WS TN Film] BUT WHICH EXACTLY?
2430T: 1ms G2G + 144Hz [24"WS AU Optronics TN Film] BUT WHICH EXACTLY?
2411T: 1ms G2G + 120Hz [24"WS TN Film] BUT WHICH EXACTLY?

BY THE WAY:
Asus VG248QE 1ms G2G + 144Hz [24"WS AU Optronics TN Film (M240HW01 V8)]
USING THE SAME PANEL AS 2411Z
I'll need to find out MORE AND MORE...
This is REALLY A CONSPIRACY! Selling the same crap under different price tags and categories (from cheap-mid to premium-top).

Why did you send me a private message to spam me about this topic you made?

Please don't PM me sending me tinfoil hat stupid crap. Your post is absurd and completely full of hot air which makes NO sense whatsoever. You got a defective panel. Deal with it, RMA or buy something else.

Just a fun fact:
You can flash an XL2411Z firmware into an XL2411T, but if you do this using Linux's flashrom, the DVI/VGA/HDMI information will be corrupted and will be reported as a non PNP monitor unless you flash the DVI EDID directly or you use the Mstar ISP programming device). Low blue light will work, but the "lightboost" strobe (brown? green?) wire used to send the strobe signal in Lightboost mode won't send the strobe signal; blur reduction will cause the monitor to gain a too high brightness level or hardware power cycle/reset itself, and brightness levels will be reduced due to the DC voltage circuit missing (the XL2411T uses PWM, although later versions were rumored to be PWM free).

I know more about the Benq monitors than anyone besides Strobemaster (and I actually know more about the firmware bugs), and I can tell you your post is full of complete crap.

Ok, respect brah, you asre so smart. But what to choose from this list then?

1) BenQ 2720Z for 465 EUR - awesome but expensive
2) IIYAMA ProLite GB2488HU-B1 for 272 EUR - really good but I prefer 27"
3) IIYAMA ProLite GB2788HS-B1 for 345 EUR - Can it handle overdrive(blur reduction) + 144Hz? If so it maybe one of the best monitors for that price, right?

And also.. it means that this digitalversus.com reviews are bs? Because they are telling us that 2411Z is extremely bad, when 2411T is awesome.

 

[Falkentyne]

In no way am I smart. I just do my research in an OCD obsessive way, nothing more.
And I know nothing about those screens. I personally love blur reduction but I would not recommend the XL2720Z to anyone unless they wanted to focus purely on backlight strobing.

I have 3 BenQ 144Hz monitors myself.

BenQ XL2420Z - 1ms G2G + 144Hz - 24"WS AU Optronics TN Film (M240HW01 V8)
2 x BenQ XL2411Z - 1ms G2G + 144Hz - 24"WS AU Optronics TN Film (M24HW01 V8)

Using them in nVidia surround view 5880 x 1080 (bezel corrected) @ 120 Hz. XL2420Z in the middle, XL2411Zs on the side.
I got them in April 2015 and the monitors had V1 firmware in.
I was not happy with the picture quality.

I updated the firmware using a linux PC and configured them according to instructions from the Blurbusters forums

http://forums.blurbusters.com/viewtopic.php?f=13&t=471
http://forums.blurbusters.com/viewtopic.php?f=13&t=779

including firmware update to V2 (and later to V3)
Installed and configured the BlurBusters Strobe Utility
Installed the ICC profile from TFTcentral DB; http://www.tftcentral.co.uk/articles/icc_profiles.htm
Made custom colour profile in monitor like described for tftcentral icc profile.
Made the custom resolution (120hz and set the total vertical pixel to 1350)

For me the difference was like night and day. The picture quality was much improved. Brighter, more saturated colours,....

Anyhow, it is still not as good as IPS panel, especially not in terms of brightness, contrast ration and colour accuracy.
But I find the image clarity, responsiveness, lack of blur is just way better in my BenQs.
I use them @ 120Hz as I find the brightness and colours better compared to 144Hz.

Setting them up was a **** load of work. I spent several evenings browsing the forums, flashing firmware and configuring the monitors.
Not the way it should be. I was an early adopter with V1 firmware on the monitors. Do not know how much better it is with monitors you get from the shops today, but the amount of work I had to put in to be happy with the monitors was in my view really not acceptable.

I have compared the monitors to few DELL IPS panels (U2711, U2715H) and to Asus ROG Swift PG278Q.
No way I'm going back to 60Hz. The Asus ROG would probably been my choice, but I wanted a surround view and 3 of them would have been too expensive and probably too much for my graphics cards to handle ;-)

My gaming is mostly online combat flight simulators (DCS, IL2, WarThunder,...) I wanted surround view for the added immersion.

I'm currently drooling over UWA 3440 x 1440 curved IPS high refresh rate G-synch monitors like Acer X34, but not sure I want to go that route due to all the hassle I keep reading in the forums and if it can achieve the movement clarity I get with 120Hz and blur reduction.
