The BenQ XL2420T and BenQ XL2420TX are the first 3D Vision-ready 3D LCD monitors that come with support for 3D over DisplayPort 1.1, so you actually have an alternative to using the Dual-Link DVI interface they they are also equipped with for 3D. You should have in mind however that there are some specific limitations and requirements when using 3D Vision over DisplayPort with these displays and you should be well aware of these if you plan on purchasing any of these two displays for use in stereo 3D and that goes not only regarding the use of DP. The BenQ XL2420T/TX are still the only 24-inch 3D Vision-ready monitors that support the new 3D Lightboost technology for providing increased level of brightness when in stereo 3D mode, the other two alternatives are from Asus and Acer, but they are 27-inch models and they do not feature DisplayPort connectivity. The support for 3D vision over display port has been introduced in the R290 video drivers from Nvidia and more specifically in the 290.36 Beta drivers, so it will not work with older drivers.
The BenQ XL2420T is the more affordable version that does not come bundled with 3D Vision 2 active shutter glasses and it also does not feature a built-in IR emitter for the 3D Vision glasses. This is very important, because without the built-in IR emitter you will not be able to use the HDMI interface of the monitor for stereo 3D, even if you connect an external IR emitter to your PC. Using an external infrared emitter for 3D Vision glasses gives you only the ability to use the monitor in stereo 3D mode with a PC over the DL-DVI or the DisplayPort 1.1 interface. This means that the BenQ XL2420T monitor is more suitable for gaming in 120Hz 2D mode or using for stereo 3D content only with a PC, you should not get the T-only version of the monitor if you plan on using it with a PS3 in 3D or any other HDMI 1.4-based stereo 3D-capable devices, because you would not be able to. The HDMI interface present on the BenQ XL2420T monitor is 2D-capable only and you are of course not able to use 120Hz refresh rate over the HDMI, you need to use the other interfaces for the higher refresh rate.
The BenQ XL2420TX is the more expensive version that comes with a built-in infrared emitter and a pair of 3D Vision 2 active shutter glasses, so you are ready to use the monitor in 3D mode over DL-DVI, DisplayPort or HDMI 1.4. Using this monitor over the DisplayPort interface however has some limitations based on the GeForce GPU you have in your computer, so have in mind that if your video card is based on GeForce 8 series, GeForce 9 series, or GeForce GTX 295/280/260 GPU you would still need an external IR emitter to use the monitor over the DP interface. Of course this is only related to using DisplayPort, if you have any of these older GPUs you can still use the built-in IR emitter over the DL-DVI interface. If your GPU is any newer you would be able to take advantage of the DisplayPort 1.1 connectivity with the built-in IR emitter inside the display. And one more thing, currently NVIDIA 3D Vision Surround setups are still not supported over DisplayPort, so if you plan on using a three monitor 3D setup, then you’ll have to stick to using the Dual-Link DVI interface for now.

We have already heard that BenQ is going to refresh their first 3D-capable LCD gaming monitor XL2410T with a new model that will support Nvidia 3D Lightboost technology and come bundled with the new 3D Vision 2 active shutter glasses – BenQ XL2420TX, as well as BenQ XL2420T that won’t have glasses bundled, but now there is also an official announcement. BenQ advertises these models more as gaming monitors (developed with the help of pro-gamers) and not as being 3D-ready, with a lot of features especially optimized for gaming in fast paced action games such as FPS titles. I’m however more interested in the use of these new 24-inch LCD monitors for stereoscopic 3D gaming and general stereo 3D use…
BenQ XL2420T / XL2420TX monitor specifications:
Screen Size: 24″ WLED-backlight, TN Panel

Pixel Pitch: 0.276 mm
Viewing Angle (L/R;U/D) (CR>=10): 170 / 160
Video Terminals: D-sub / DVI-DL (Dual Link) / HDMI x 2 / DP 1.2 / Headphone Jack
USB Hub: Donwstream x3; Upstream x1 ports
Features: Black eQualizer, Smart Scaling, FPS Mode, RTS Mode, Game Mode Loader, NVIDIA 3D Vision 2 ready, Senseye 3, AMA, HDCP, K-Locker mount
Adjustments: Height adjustment: 130mm, Tilt (down / up): -5 / 20, Swivel (left / right): -45 / 45, Pivot: 90°
Power Consumption: 24 W (Based on Energy Star 5.1 test criteria)
Dimensions (HxWxD): 571.4 x 516.9 x 149.9 mm
Weight: 6.1 kg.
The design of the new BenQ XL2420T/TX certainly looks nice, the extra adjustability of the stand is a plus, the extra remote for controlling the display settings called S Switch is an interesting concept, the Game Mode Launcher for using monitor settings profiles… the whole thing looks really promising. The specifications also look fine, but what caught my eye in them was the lack of information if the HDMI interface is 1.4 and 3D-capable or not as well as the fact that the monitor also has a Display Port 1.2 interface. The monitor features an FPS mode as well as apparently an RTS gaming modes, but there is also no information if and how these affect the responsiveness of the display and especially if there is input lag or not. So there are some important things still unknown about the new series from BenQ that we’ll probably soon find out about as BenQ XL2420T/TX should hopefully be available on the market by the end of this month in Europe with a price range of about 300-400 Euro.

Nvidia has officially announced their new generation of 3D Vision active shutter glasses called just Nvidia 3D Vision 2. The new glasses offer significant advantages over the first generation that was already getting old, so it is indeed great news that Nvidia is bringing a new and updated version of their 3D glasses. But along with the announcement of the new glasses, the company also introduced NVIDIA 3D LightBoost technology, a new display technology that is expected to bring much brighter and richer in color 3D image as well as significantly reduced ghosting. The NVIDIA 3D LightBoost technology is expected to be available in the new generation of 3D Vision compatible 120Hz 3D LCD monitors and displays, most of which will also come with the new 3D glasses bundled.
The new Nvidia 3D Vision 2 glasses come with a new more comfortable and functional design intended to make them fit better even when wearing headphones and not to bother you even if you play for hours with them. The new design also improves on other areas such as better ambient light blocking of external light sources and thus less noticeable flicker around te display if you have the light in the room on while you use the 3D mode. Among the notable functional improvements is the 20% increase of the lens size and up to two times brighter image when in 3D mode and used together with a new 3D monitor supporting the 3D LightBoost technology, also making it easier to see your mice and keyboard through the glasses and of course with further reduced crosstalk/ghosting.
The new Nvidia 3D Vision 2 glasses will be fully backwards compatible with older and already available 3D Vision capable 3D monitors and they will work with the new models that come with NVIDIA 3D LightBoost technology, but for the best experience it is recommended to use them with a new generation display. The same goes for the first generation of 3D Vision glasses, they will be fully compatible with the new 3D Vision displays, so if you already have a few pairs of these like me don’t be in a hurry to get rid of them, it is just that with the new glasses you will be getting better results.
As far as the pricing and availability, the new 3D Vision 2 glasses kit should be available by the end of October for $149 USD in US and an extra pair of 3D Vision 2 glasses (without IR emitter) will be available for $99 USD. These are the same prices that the old 3D glasses had up until now and with the new version announced it will start replacing the previous model out of which Nvidia says it has been sold over half a million pairs of glasses.
According to Nvidia the first 3D LightBoost-certified desktop display is going to be the the 27-inch ASUS VG278H, a model that we are expecting to hit the market for quite a while now, featuring both Dual-Link dVI interface and 3D-capable HDMI 1.4 input as well. The ASUS VG278H monitor is expected to be available by the end of October 2011, it will come bundled with the new 3D Vision 2 glasses and should be priced at $699 USD. And my expectations for this display just got even higher, not only because it will come with the new glasses, but also because of the use of Nvidia’s LightBoost technology and the promise that the crosstalk/ghosting in 3D mode is significantly reduced as compared to what we currently have available on the market. That of course will need to be verified and I’m expecting very soon to have a test unit of the 27-inch ASUS VG278H 3D monitor in order to compare it to other displays I’ve already tested. In November we should start seeing other manufacturers of 3D monitors to start releasing updated versions of their 3D models such as the new Acer HN274HB, or the BenQ XL2420T and XL2420TX (a model with and without the new glassed bundled with the display), so if you are currently considering what 3D Vision ready monitor to get, then it might be a good idea to postpone your choice for a bit and get one of the latest models. The first 3D LightBoost compatible notebooks include several Toshiba models – Satellite P770/P775, Dynabook Satellite T572, Dynabook T572, and the Qosmio X770/X775 expected also by the end of this month with others soon to follow.
I’ve just got a pair of the new 3D Vision 2 glasses for reviewing, so you can expect more a lot more information and first-hand impressions in the next few days, so stay tuned and get ready to upgrade your stereo 3D gaming gear for the holiday season as we are also expecting a good selection of top game titles that will come with 3D Vision support as well…
