New 27-inch BenQ XL2720T 120Hz and 3D Vision Ready Monitor

March 29th, 2013 · 10 Comments · General 3D News


BenQ has introduced their first 27-inch BenQ XL2720T 3D-capable gaming monitor supporting 120Hz refresh rate in that is compatible with Nvidia’s 3D Vision and supports 3D Lightboost technology (it seems that the display does not support 144Hz unlike the smaller 24-inch XL2411T). In fact the Asus VG278H and the BenQ might use the same LCD panel (not the VG278HE that supports 144Hz as BenQ’s display may not support 144Hz). The BenQ XL2720T is essentially a larger version of the smaller XL2420T model that the company offers that includes all of the extra features available in the 24-inch model, unlike the more stripped down BenQ XL2411T model. Have in mind that just like the case with the Asus VG278HE, the BenQ XL2720T also does not come with a built-in 3D Vision IR emitter or 3D glasses bundled, these monitors are 3D Vision-ready, but you need to buy the full 3D Vision kit separately if you want to use them in stereo 3D mode. And since a lot of non-stereoscopic 3D gamers have already shown a lot of interest in such monitors because of their high refresh rate and the ability to use the 3D Lightboost technology in 2D mode in order to eliminate the motion blur the market for 3D-ready monitors has grown a lot. In fact if we take a look back lately we’ve seen companies releasing 3D Vision-ready monitors without integrated IR emitters and bundled 3D glasses that are targeted as much to the normal gamers as they are to the stereo 3D gamers.

BenQ XL2720T Specifications:

Panel Size: 27-inches
Monitor Type: TN TFT-LCD with LED Backlight
3D Technology: Active 3D, 3D Vision Ready
Pixel Pitch: 0.311mm

Power Consumption: On Mode 27W (typ.); Sleep (Standby) <0.5W Phys. Dimension (WxHxD): 548x642x273 mm Weight with stand: 7.5kg

The BenQ XL2720T monitor is starting to appear on the market in some countries, but unfortunately the availability is still quite scarce and it is hard to find. It is still not available in my region either and since the new and more expensive BenQ displays here are not always available in a timely manner I can only order it online from abroad in order to test it, so I’ve decided to try out something else along with you, the readers of the blog, and if it works out with the BenQ we can continue doing it so it can greatly help in having timely reviews of new 3D-capable hardware and to have much more hardware reviewed…

The BenQ XL2720T Monitor Review Fund has so far collected 12.63 Euro (2.7% of the Goal).

Here is a PayPal donation button that you can use to donate for the BenQ XL2720T Monitor Review Fund, we need to collect around $600 USD (~470 EUR) for the price of the monitor and I’ll cover the shipping (in Europe hardware is more expensive than in the US). So if 600 people donate $1 each (or 470 people 1 Euro each) I’ll be able to quickly order and test the BenQ XL2720T and after I finish someone who has donated for the monitor test fund will get to keep the monitor. Unfortunately due to the large size and weight of the displays only people in Europe will be able to participate in draw for the monitor, though anyone is welcome to help in donating for the monitor test fund. I’ll cover the shipping costs of the monitor to the person who is drawn to receive it and if he is in an EU member country he will not have to pay anything extra, for non-EU member countries in Europe there could be some customs tax, so have that in mind. Unfortunately calculating the shipping cost using different courier companies for overseas shipping to America or Asia for example gave frightening results – the shipping cost may end up more than what the monitor actually costs, so that is why only people in Europe will be able to participate in the draw for the monitor. So when donating for the BenQ XL2720T Monitor Review Fund make sure you note if you want to participate in the drawing of the test monitor as a prize after it has been tested and reviewed or not. Again everyone is welcome to donate to the fund for buying the monitor for a review, but only people that are from Europe will be able to participate in the draw giving them the chance for winning the monitor after the review is finished. There is no limit or requirement on the sum you can donate for the monitor test fund, so it is up to you to decide on the amount you are willing to donate and if you are willing to do it at all.

Review of the Benq XL2411T 3D Vision-ready 3D Monitor

March 12th, 2013 · 19 Comments · GeForce 3D Vision


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 Specifications:

Panel Size: 24-inches
Monitor Type: TN TFT-LCD with LED Backlight
3D Technology: Active 3D, 3D Vision Ready
Pixel Pitch: 0.276mm
Brightness: 350 cd/m2
Contrast Ratio (typ.): 1000:1, 12,000,000:1 (dynamic)
Response Time (typ.): 5ms, 1ms GTG
Viewing Angles: 170° (H) / 160° (V) @ C/R > 10
Input: D-sub, DL-DVI, HDMI
Power Consumption: On Mode 22W (typ.); Sleep (Standby) <0.5W Phys. Dimension (WxHxD): 420x652x251 mm Weight with stand: 6kg


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.


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.


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.


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.


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.


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.

The PC Version of Sleeping Dogs Will Have 3D Vision Support

August 13th, 2012 · 25 Comments · Stereo 3D Games

Sleeping Dogs is an upcoming open world third-person action adventure game with role-playing elements where you take the role of an undercover police agent trying to infiltrate a Triad organization in Hong Kong. The game should be available for PC, PlayStation 3 and Xbox 360, though only the PC version will have stereoscopic 3D support for 3D Vision users along with some other extras that PC gamers with more powerful rigs will be able to take advantage from according to the game’s developers. Among these are a high-resolution texture pack, better shadows, DirectX 11 features, multi-core CPU and GPU optimizations and support for multi-monitor setups for both AMD and Nvidia-based graphics cards. It is interesting to note that there is a mention of “Nvidia 3D Support” and not information that the game will be 3D Vision-ready, I just hope that we are not in for another Alan Wake and 3D support situation as Sleeping Dogs looks like it can be great in stereoscopic 3D mode.

Sleeping Dogs will be released on August 14th in North America and apparently it will be available only in a downloadable version, August 16th in Australia, August 17th in Europe in both Retail and Downloadable version and on September 27th in Japan where it will be released under the name Sleeping Dogs: Hong Kong Secret Police. The Japanese version will apparently have some censoring as well as the German version that will be delayed for some time after the official European release.
