benq-xl2411t-monitor


Benq XL2411T is the latest 24-inch 3D Vision-ready monitor from BenQ, you can say that is the third generation of 3D-capable displays that BenQ releases with the first one (XL2410) having some issues with backlight bleeding at first and the second ones (XL2420T/TX) a bit more expensive and with limited availability of the TX version. Benq XL2411T comes as the successor of the Benq XL2420T with some improvements and with some extras removed, making the price much more attractive for a 120Hz gamer-oriented 3D-capable display that does not come bundled with integrated Ir emitter or 3D Vision glasses, so you need to buy them separately (a full kit, not just the glasses) or already to have them if you do plan to use it in stereo 3D mode. But how good is the XL2411T considering the fact that it is a gamer-oriented product and featuring some specially designed features for gamers, even though these re mostly available for 2D gaming, letus find out…

benq-xl2411t-3d-monitor-at-120hz-3d-mode


BenQ originally advertises the Benq XL2411T as a 120Hz monitor, however the display fully supports 144Hz refresh rate out of the box, this is actually one of only the three 144Hz-capable monitors currently available on the market. Have in mind though that the 144Hz refresh rate is only available for 2D, when you activate the stereoscopic 3D mode using 3D Vision you are going to be limited to 120Hz max as this is what is supported by 3D Vision. This is probably the reason that BenQ has decided to advertise the display as a 120Hz model, even though it supports 144Hz in 2D mode, however the 24Hz higher refresh in 2D mode is something that is going to attract the attention of gamers not interested in using the display for stereo 3D. The focus of this review is going to be mostly on the stereo 3D capabilities and performance of the monitor should you decide to go for it for using in stereoscopic 3D mode with 3D Vision. Unfortunately I’ve had access to the display for just a few hours, so I was not able to do a very thorough testing and I’ll have to get one unit later on for some extra testing, but I still have managed to test the most important aspects in order to be able to compare it with other 3D monitors I’ve already tested here.

Before going on to the tests I should make one thing clear, and that is the fact that the BenQ does not have support for HDMI 1.4 and thus no 3D frame packaging mode will be available die to the fact that there is no IR emitter for the 3D glasses built in. The monitor can only be used in 3D mode via the Dual-Link DVI port and in frame sequential mode and is only supporting the Nvidia 3D Vision technology. The fact that it does not have built-in emitter and glasses bundled makes it available at a more attractive price for people that already have an older 3D Vision monitor and want to upgrade to a newer one and already have 3D Vision kit that they can use with it.


benq-xl2411t-monitor-uncalibrated


Now, let us move into the tests of the BenQ XL2411T. I’m starting with the usual check of the default color accuracy of the display which isn’t very good, something that I’ve noticed even before measuring the color performance. The monitor does seem very bright and the colors are looking washed out with the factory settings, even though the measured maximum brightness is just a bit over 300 cd/m2. I’ve seen 3D displays with higher brightness perform better than this one and the BenQ has the potential to go even higher in terms of maximum brightness as the factory settings are far from bringing it to maximum.


benq-xl2411t-monitor-calibrated


What has surprised me even more was the fact that after trying to calibrate the color reproduction of the display the results were far from great, even though there was a significant reduction of the brightness (the image above shows the best achieved results). Even playing with the advanced settings such as the RGB sliders didn’t help much in improving the situation. I’ve even tried different inputs and different systems with various hardware as I was expecting to be able to get more accurate results after a calibration, even though we are talking about a TN panel. I’ve seen many 3D-capable TN-based LCD displays get surprisingly good color accuracy after calibration, but I’ve also seen others that could be even worse than the results shown by the BenQ. I suspect that some of the extra features available in the menu of the BenQ could be influencing badly the color reproduction such as the Black eQualizer or the AMA mode (Advanced Motion Acceleration) set to High by default (essentially a control for the monitors Overdrive to make the pixel response faster), but I did not have enough time to play with them to see.


benq-xl2411t-extreme-crosstalk-test


I was pleasantly surprised that the BenQ XL2411T did not have issues with backlight bleeding, and the screen’s backlight seems quite even, at least to the naked eye, though there are some slight variations when measuring it. The extreme crosstalk/ghosting test to black and white I’m using to compare 3D monitors also did show very good results, perfect on the white and very good on the black. I was a bit surprised to see that the BenQ XL2411T has the Contrast level set to a value of just 37 by default when in stereo 3D mode, it is a very bright panel, so this does not make it a problem and apparently it could help to drive down the level of crosstalk/ghosting as we’ve seen in other 3D monitors where lowering the Contrast value can help.


benq-xl2411t-sailboats-test


The sailboats crosstalk/ghosting test is also showing very good results with very faint traces of ghosting that you may not even see normally, so we can consider the result here to be really good indeed.


benq-xl2411t-tru-top
benq-xl2411t-tru-bottom


The test for crosstalk/ghosting with the game Tomb Raider Underworld reveals some interesting results, the top of the screen has not problems with the crosstalk, however the bottom part shows the familiar color ghosting/crosstalk that is a direct result of too aggressive Overdrive leading to the inversion of the image. And playing with the Contrast level has little effect of the strength of this effect, so it can be effected only by playing with the Overdrive if possible on the BenQ XL2411T. In fact you don’t need to have very aggressive overdrive when running in stereo 3D mode at 120Hz like you may need in 144Hz 2D mode, but unfortunately many of the additional functions for controlling the monitor are locked out when you are in stereo 3D mode and you have no control over them.

So what is the conclusion for the Benq XL2411T 3D-capable monitor? The monitor comes at a very reasonable price unlike the previous XL2420T for example that was more expensive due to some extras that you could easily live without, it performs quite well in both 2D and stereo 3D mode, feels very responsive with minimum input lag, something that is a must for a gamer-oriented product such as the XL2411T. What I did not like that much was the color accuracy, not that this monitor would be used in color critical applications anyway, but it could’ve been better and calibration should’ve helped more as well as the fact that the Overdrive could be more aggressive at times without the need for that resulting in more crosstalk/ghosting. There is a possibility that these two negatives for the display could be improved, but I’ll need some more time with the BenQ playing with it and tweaking it to figure out if it is possible to further improve the results. Another thing that could be just a bit annoying is the slower transition time in and out of the stereo 3D mode, something that is probably related to the activation/deactivation of the 3D Lightboost technology (the advanced control of the backlight), not a problem if you force the 3D Lightboost to be always on even in 2D mode to reduce the motion blur. The monitor has high brightness and has the potential to use the 3D Lightboost technology while in 2D mode as well, though this will limit you to 120Hz maximum refresh, but the combination of 3D Lightboost in 2D mode at 120Hz could prove better than 144Hz in 2D mode without the 3D Lightboost active (also a matter of preference really). In the end the Benq XL2411T 3D Vision-ready monitor can turn out to be a quite good choice for 2D gamers switching for a 60Hz monitor and for stereo 3D gamers that are using an older 3D Vision-ready monitor already an need to upgrade (pre-Lightboost model). If you however already use a 3D-capable monitor with 3D Lightboost support for gaming in either 2D or stereo 3D, then you can safely skip the BenQ and wait for something even better.

    very well bloody!

  • 3 Bloody // Mar 12, 2013 at 20:11

    Unfortunately I’ve had access to the monitor for very little time and could not test everything I wanted to, but i hope to get another unit soon for extra testing and I’ll share more results and findings about it.

  • 4 Crystal Cowboy // Mar 13, 2013 at 00:46

    Will you be able to test 3D stereo over Displayport later?

  • 5 Bloody // Mar 13, 2013 at 01:28

    Crystal Cowboy, the BenQ XL2411T does not have DisplayPort like the previous model XL2420T does, apparently this is one of the things that got removed to lower the price.

  • 6 GDL // Mar 13, 2013 at 05:00

    I thought Display Port was the new “standard” that was gonna replace HDMI and DVI in price o.O

  • 7 Crystal Cowboy // Mar 13, 2013 at 18:09

    No Displayport: You’re right; I verified this at the manufacturer’s web site. I wonder what’s up with that.

  • 8 Bloody // Mar 13, 2013 at 19:03

    Adding DisplayPort, even though there are no royalties to pay to use it like with HDMI for example, still requires support on the controller board and apparently makes the price of the product higher. There is still some time before DP becomes more widely used and supported, but with resolutions higher than Full HD the adoption rate should increase…

    Bloody, do i need 3d vision 2 kit to play in 3d ? becouse i want to buy original 3d vision 1, its much chepaer

  • 10 Bloody // Mar 20, 2013 at 01:29

    It will work just fine with the original 3D Vision kit as well, the old glasses also fully support the 3D Lightboost technology.

    Hey Bloody really nice review, i have a question tho

    I have a laptop and i am planning to get this as my external monitor because of its 120hz refresh rate (planning to go NON 3D 120hz), however my laptop does not support DL-DVI connection and D-sub is not an option (since i dont think D sub support 120hz).
    So my only option is to use HDMI, and i heard from the IT support store guy HDMI 1.3 can support 120hz for my laptop
    Is this true? and does this benQxl2411t support HDMI 1.3?
    from your review it says it does not support HDMI 1.4

    Thanks much

  • 12 Bloody // Aug 26, 2013 at 22:12

    HDMI is not an option for 120Hz support, you need a Dual-Link DVI or DisplayPort for that, if you don’t have either, then don’t bother getting this monitor as you will be limited to 60Hz.

  • 13 bukcik // Aug 27, 2013 at 06:32

    Thanks so much for the reply bloody

    I have an ASUS G75VW and I think I have a mini display port on my laptop, but does benQxl2411t support mini display port? If so I can just get a display port cable and run 120hz on the benQxl2411t from my ASUS g75vw correct?

    Thanks

  • 14 Bloody // Aug 27, 2013 at 11:03

    This monitor does not support DisplayPort, however if you have a DisplayPort connector on your laptop you should be able to use an active DisplayPort adapter to Dual-Link DVI to use the display at the higher refresh rate. Note that it should be an active adapter converting DP to Dual-Link DVI as there are a lot of cheaper passive single-link adapters that will not work.

  • 15 bukcik // Aug 27, 2013 at 12:39

    Thank you so much for your answers

    So if I use the active DisplayPort adapter to Dual-Link DVI it will give me 120hz on the BenQxl2411t, will it do something bad to my laptop tho?

  • 16 Bloody // Aug 27, 2013 at 15:15

    Yes, and there will be nothing bad happening with your laptop :)

  • 17 bukcik // Sep 9, 2013 at 11:25

    Hi Bloody It’s me again hahaha

    I’ve decided to try out BenQXL2420TE (has display port) to connect to my ASUS G75VW ( my laptop has a mini display port/thunderbolt) to get an output of non 3D 1980*1080 @120Hz, do you think mini display port to display port cable will be able to do this? ( I am thinking of getting the mac cable one, or do you have any recommendations?)

    Thank you

  • 18 Bloody // Sep 9, 2013 at 11:34

    If the monitor supports 3D over Display Port you can connect it directly without the need of additional adapters. And I think that only BenQ has some monitors that support 3D over DP.

  • 19 Bukcik // Sep 26, 2013 at 12:11

    Hi Bloody

    I’ve managed to get smooth 144 Hz through mini display port to display port from my laptop to a BenQXL2420TE :D, but sometimes ( had the monitor mine for like 3 weeks) when I open an application either games or browsing ( happened only 3 times during that 3 weeks) the monitor will go black and theres a message saying ” out of range”, to fix this I can either unplug and replug my display port cable or just turn off and turn on the monitor again and the monitor will run smoothly again in 144 Hz. But I am just curious what is going on with that ” Out of Range ” Error? What is causing it?

    Thank you so much
    Buk
