Planar SA2311W, a New 23″ 3D Vision Ready 120Hz LCD Monitor

November 4th, 2010 · 8 Comments · GeForce 3D Vision

Certainly an interesting move, coming from one of the leaders in high-end stereoscopic 3D monitors, Planar Systems, that is soon going to have a 23-inch 3D Vision compatible LCD monitor. The Planar SA2311W 3D monitor is a single panel solution with a 120Hz refresh rate and Full HD resolution, designed more for 3D entertainment than work, unlike the much more expensive stereo 3D display that the company offers and that are made to be used for professional work with S3D content. The new 3D LCD monitor form Planar is designed to be compatible with Nvidia’s 3D Vision active shutter glasses and although still not a lot of details about it are available, it is most certainly something to look for with interest. Planar has announced December as a release date for their SA2311W 3D monitor with a price of $449 USD. There is still no support for it in the latest 3D Vision drivers, but we’ll probably see it added in the next update as there is one month before the monitor will actually be available on the market. One thing that I’ve noticed about this upcoming monitor is that it will have a built-in function to control the OverDrive (OD) right inside the normal OSD menu… which is good as it should help in getting better image quality when in 2D mode.

Planar however did not stop at only a 3D Vision ready monitor, but also have designed a special keyboard for professional users of 3D monitors such as the Planar SA2311W 3D monitor (this is not talking about a gaming keyboard). What is interesting about this keyboard is that it offers seven adjustable light levels (plus off function for the backlight of course), so that you will be able to adjust it in order to see your keyboard’s keys through active LCD shutter glasses. One of the issues that is associated with the use of active shutter glasses is that they block some of the light reaching your eyes and when you work in darker environment, even if your keyboard has a backlight for the keys you may have trouble seeing which key is which through the glasses. So the Planar ProGlow keyboard is here to help, by offering a classical and reliable design along with blacklight that can allow you to still see the markings n the keys clearly through your glasses and in cool green color. The only not so good thing about this product is the price you’ll have to pay for it which is $185 USD.

Testing the Asus VG236HE 120Hz 3D Monitor, it Has Some Input Lag

November 3rd, 2010 · 9 Comments · Other S3D Tech

After some delay I’ve finally gotten my hands on the Asus VG236HE (the version without bundled 3D Vision glasses) which is the same in terms of hardware and performance as the Asus VG236H which comes with the shutter glasses bundled. As you probably know the Asus VG236HE is one of the latest 120Hz 3D-capable LCD monitors compatible with Nvidia’s 3D Vision technology, but what sets it apart from all other such products is the fact that this is the first 3D-capable 120Hz LCD monitor with a glossy screen, as all others so far were with matted screens (apart from the 120Hz LCD panels used in 3D-capable laptops that are also glossy). Now this kind of reflective coating over the screen can create some reflections when darker image is being displayed and some people do not like that much, although more and more monitors in general are being made like that, but you can get used to that or just avoid it by choosing another product. But I’ll leave that for when I’m ready with the whole review of the monitor, and for now let me just show you how the monitor performs in terms of input lag.

I’ve decided to compare the Asus VG236HE to the LG W2363D-PF I’ve recently tested, as this model from LG is so far the only Full HD 3D-capable 120Hz LCD monitor that I’ve tested and that does not have input lag when the special THRU Mode is active. So far the only model from the second generation of 3D-capable 120Hz LCD monitors that I still haven’t been able to test is the Alienware Optix AW2310, which apparently also does not have any input lag according to some reviews I’ve read. So dusting off my DVI splitter cable I connected both the Asus VG236HE and the LG W2363D-PF and started testing for input lag with the LG in its THRU mode and the Asus set in its gaming mode…

As you can see from this photo, there were moments when the LG and Asus were performing the same, meaning that there was no input lag at the specific moment, unfortunately the situation was not like that all the time. The minimum input lag measured on the Asus was indeed 0 milliseconds, meaning no delay at all from the moment of receiving the image and displaying it on the screen, however the average and maximum delay was more than zero.

The maximum input lag I was able to measure was 17 milliseconds which is not that bad, but for a high-end gaming monitor with 120Hz refresh rate and intended for playing games in stereo 3D mode one would expect to have no input lag at all, right?

And the average delay measured was about 8 milliseconds for the Asus as compared to the LG, that has no input lag at all or at least it is much less than one millisecond making it really insignificant and hard to measure anyway. So 8 milliseconds was the average input lag measured from the sequence of over the 300 photos, taken in high-speed mode with a digital camera, of the timer you see shown on both displays to measure the input lag. So the Asus doesn’t have so good start, especially for gamers looking to use it in 2D mode with the full 120Hz refresh rate, but lets see the more important part – how well it performs in stereo 3D mode. That however you will be able to soon read when I’m finished testing the monitor in a few days… ;)
