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.

Problems With Asus VG278H 3D Monitor and the Integrated IR Emitter

November 23rd, 2011 · 28 Comments · GeForce 3D Vision

There were already a few people that complained of not being able to make their 3D Vision 2 active shutter glasses work with the new Asus VG278H 3D monitor that comes with integrated IR emitter. And apparently some units do have a hardware issue with the IR emitter itself and the problem is not software related at all. So if you have a similar problem you can get into the monitor’s menu and take a look at the Information menu of the display to see if your monitor also does not detect the IR emitter as connected (as in the photo above posted by milkman in the forum). If you see the red error message then there is something wrong with the emitter and it is a hardware issue and not a software one, so you should get a replacement unit as clearly you’ve got a defective one. Normally the Information menu should not have the red error message and then the issues of not being able to make the 3D glasses activate could be software related. So make sure to check what your Asus VG278H monitor reports as it could save you a lot of trouble…

More on Ghosting and Brightness of the Asus VG278H 3D Monitor

November 9th, 2011 · 26 Comments · GeForce 3D Vision

The new Asus VG278H 3D Vision-ready 120Hz LCD monitor has an interesting option in the OSD menu that allows you to control the level of the 3D Lightboost and thanks to that I was able to try some interesting things. In the review of the Asus VG278H 3D monitor I have already mentioned that there are some things that you can do in order to improve the results you will get when using the monitor. One example for that is to reduce the Contrast level from the default setting of 76 to 55 in order to reduce the level of ghosting/crosstalk in stereo 3D mode without sacrificing too much of the brightness and that is possible thanks to the 3D Lightboost technology that increases the brightness level. I’ve used a colorimeter to measure the level of brightness with the different settings of the Contrast level with the Lightboost set to the maximum level and here are the results:

Contrast 100: 202 cd/m2
Contrast 76: 160 cd/m2
Contrast 55: 111 cd/m2

And here is the level of brightness with the default setting for Contrast of 76 and different level of the Lightboost setting, from completely off to the maximum:

Off: 85 cd/m2
+1: 90 cd/m2
+2: 95 cd/m2
+3: 102 cd/m2
+4: 111 cd/m2
+5: 120 cd/m2
+6: 128 cd/m2
+7: 136 cd/m2
+8: 144 cd/m2
+9: 152 cd/m2
Max: 160 cd/m2

Notice that from the Off state of the Lightboost technology to the maximum level there is almost a double increase of the brightness level and what Nvidia was saying for the new technology was that it will increase the brightness twice. So you can say that this claim is true. Notice that the level of brightness you get with the decreased Contrast to a setting of 55 is the same as the +4 state of the Lightboost setting together with the default setting for Contrast. So you are kind of halving the effectiveness of the Lightboost technology in order to further reduce ghosting/crosstalk.

In order to further reduce the ghosting in 2D mode as well you can also play with the Trace Free option of the monitor. The default setting of 60 is quite Ok (the left part of the image above), but increasing it to the maximum value of 100 you get better results (the right part of the image above). You can see from the high-speed photos taken from the PixPerAn test software that the fast moving objects are looking better and have less ghosting with a higher value of the Trace Free function.
