Asus Going Past 120Hz, Meet the New 144Hz Asus VG278HE 3D Monitor

July 26th, 2012 · 21 Comments · General 3D News


Asus is apparently preparing to release a new version of their 27-inch Asus VG278H 3D monitor that does not come with built-in IR emitter or 3D Vision 2 glasses bundled. The new model name is Asus VG278HE, much like what Asus did with their previous 3D Vision-Ready model VG236H and the VG236HE that also did not include 3d Vision bundled. This time however Asus did announce something different and new in the Asus VG278HE display – support for 144Hz refresh rate, something that was not available in the VG278H model. So what Asus is trying to do with the VG278HE is clearly target it at gamers that are not that much interested in stereoscopic 3D support, though the monitor is still 3D Vision-capable if you get an additional 3D Vision kit, but want to have even higher refresh rate when playing in normal non-stereo 3D mode. Other than the support for 144Hz refresh rate (the first LCD monitor to support that) and the lack of built in IR emitter and bundled 3D Vision glasses the rest of the specs of the display are pretty much the same as with the Asus VG278H, though the new model should be available at a more affordable price.

Have in mind that the 144Hz refresh rate is not supported in stereoscopic 3D mode, only in 2D and it should only be available when using the DVI interface with a Dual-Link DVI cable, even though Asus is not totally clear on that, not to mention that the 144Hz refresh rate is also not mentioned in the manual of the display where the supported resolutions and timings are listed. Furthermore Asus talks about HDMI 1.4 and stereoscopic 3D support, but this monitor does not have a built-in IR emitter, so how did they manage to provide that with an external IR emitter for 3D Vision is another thing that is not yet very clear. I guess we’ll have to wait some more time for the product to become available on the market, so that we can see it in action and test it and compare it with the VG278H. This way we’ll learn more about the new 144Hz mode and the claimed HDMI 1.4 3D support.

The 3D Vision 2 and 3D Lightboost Monitors Are Still Hard to Get

February 17th, 2012 · 9 Comments · Other S3D Tech


There are still only three brands offering 3D Vision 2 and 3D Lightboost equipped active 3D monitors for use in stereo 3D mode with Nvidia-based graphics card and these monitors are still quite hard to find and get in a lot of markets. Asus VG278H, the first 3D Lightboost-capable display with 27-inch size to appear on the market a few months ago was plagued with a lot of user complaining with different issues with it, the most serious one was with backlight bleeding. Asus has meanwhile fixed the issue apparently with a new revision of the display that should be already available for sale, but that left a bit of a hole in the market that still hasn’t been filled with new monitors. Next up was BenQ with their XL2420T and XL2420TX 3D Lightboost-capable 24-inch models that have taken quite a lot of time to actually start appearing on the market. BenQ XL2420T being a 120Hz version intended mostly for non-stereo 3D gamers as it does not feature built-in IR emitter and doesn’t have glasses bundled, also not supporting 3D over HDMI 1.4. This model is now more easy to be found, but it is also a bit overpriced for a 24-inch 3D-capable monitor with no glasses bundled, no IR emitter and no HDMI 1.4 3D support available. The BenQ XL2420TX, the model with 3D Vision 2 bundled, is just now starting to appear on some markets, but it is still not available in Europe for example and may not be available for a while as apparently BenQ isn’t in a hurry to launch it here. Acer has announced a new version of their 27-inch 3D monitor released last year, but the new 3D Lightboost-capable and bundled with 3D vision 2 glasses model is also called Acer HN274H with some difference in the extra few characters after the model name describing the capabilities of the display. It is actually easier to look for this monitor by its part number ET.HH4HE.B04 than to look for Acer HN274H Bbmiiid and not Acer HN274H bmiiid, although the new model might also be called Acer HN274H B as well, but that can be a bit misleading and can also refer to the older model as well. The other problem with the new Acer 3D Lightboost monitor there were also some users complaining from issues with it (I’ve also received a defective sample for testing), so now we are also waiting for something like a new revision as well from Acer…

In the end it is still hard to get any of the mentioned above 3D Vision 2 monitors in different markets around the work and often people have to resort to purchasing them online from another country which can be a bit of a problem if you happen to get a defective unit. I’m still having trouble in finding even the BenQ XL2420T to get one unit for testing here in Europe as apparently the TX won’t be appearing anytime soon. Not to mention that quite a few people are scared of getting a monitor with issues and are thus waiting to see if all the issues reported by other “early adopters” have been resolved before actually jumping the gun. So the situation is not that good, but still better that what you can get in the form of 120Hz 3D-capable monitors for sue with AMD’s HD3D technology and that are pretty much only the 23/27 and SA series of 3D monitors from Samsung that are still hard to find on some markets as well, unlike the TA models that feature only HDMI 1.4 support for example. Oh yes, I almost forgot about the Viewsonic V3D241wm-LED 3D monitor that was actually released even before the Samsung models, but is even harder to find. And while with 3D Vision if you decide to go with a slightly older model of a 3D-capable monitor, yes there are quite a few on the market of these, you can land up some really sweet deals in terms of price, there isn’t much you can do with HD3D compatible displays, unless of course you want to go for either passive 3D or HDMI 1.4-capable displays, but both come with their resolution and refresh rate limitations as compared to 120Hz LCDs using DL-DVI and/or DisplayPort interface. Hopefully the situation with 3D monitor availability and especially with more options becoming available for the people in the next few months…

3D Vision over DisplayPort 1.1 Interface with BenQ XL2420T or XL2420TX

February 6th, 2012 · 18 Comments · GeForce 3D Vision


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.
