I haven’t updated the list of the 3D-capable LCD monitors that I’ve reviewed so far here on the blog for a while, so I decided it is time to do it. In order to make it a bit more easier to find the reviews if you’ve missed them when they were published or in order to compare your device to others. I’ll also include some of the models that I still haven’t been able to review, but I do plan to test at some point if possible in order to compare them with the competition (the list is not complete with all 3D-capable products of course), so it will be easier for you to decide on what best fits your needs and requirements.

In the future I’ll also try to expand the coverage of 3D-capable products reviewed here, so that it will be easier for you, the readers to make the right choice. But it isn’t always easy to get access to all of the released products for a review, actually it is quite hard most of the time, and I don’t have unlimited resources in order to buy all the products that I want to review. So any help and support is appreciated.

Be Aware That 3D Vision Does Not Work at 144Hz on 3D Monitors

March 9th, 2013 · 1 Comment · GeForce 3D Vision

benq-xl2411t-3d-monitor-at-120hz-3d-mode


With the release of the first LCD monitors capable of running at 144Hz refresh rate that are also 3D Vision-ready there has been some confusion going on around regarding the stereoscopic 3D support that these displays can provide. There are already a few models on the market using 144Hz-capable TN LCD panels and these are: ASUS VG278HE, ASUS VG248QE and BENQ XL2411T. All of these are apparently targeted at 2D gamers as they do not have a built-in IR emitter or bundled 3D Vision glasses, but they do support 3D Vision if you have a 3D Vision kit and plug in an IR emitter for the glasses in your PC. The catch here is that these monitors can only work in 144Hz refresh rate when used in 2D mode (or plain 3D mode), but not in stereo 3D mode. If you use 3D Vision you will be limited to 120Hz as apparently 3D Vision does not support higher refresh rates yet, though it is not sure if it is just a software limitation or a hardware one like the glasses not being able to work at he higher refresh rate. Another variant is that the 3D Lightboost technology cannot function at the higher refresh rate, though that probably isn’t the case.

Nevertheless buying one of these tree models so far of 3D monitors supporting 144Hz you should be well aware of the fact that using them in stereo 3D mode will be forcing maximum refresh rate of 120Hz. Even if you are able to select 144Hz refresh and the game seems to be running at the higher refresh rate in stereo 3D, it will be forced back to 120Hz and you can easily check that from the monitor’s OSD menu in the Information panel where you can see the current input resolution and refresh rate. Now, for non stereoscopic 3D gamers the fact that stereo 3D works on up to 120Hz also means that you will not be able to take advantage of the 3D Lightboost technology at 144Hz in order to reduce motion blur. Playing at 120Hz in 2D mode with the 3D Lightboost enabled can bring significant reduction of the motion blur, making the moving images on the screen much smoother and going for 144Hz without the 3D Lightboost technology available may not be able to bring comparable results. So if you already have a more recent 120Hz-capable 3D monitor with 3D Lightboost technology support and you are considering of replacing it with a more recent 144Hz-capable solution you might want to reconsider about that, regardless if you are using it for 2D or stereo 3D gaming.

Mixing Different 3D Monitors for a 3D Vision Surround Setup

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


I often get asked various questions about the use of different 3D monitors for building a multi-monitor setup for stereoscopic 3D gaming – 3D Vision Surround as well as for non-3D use, the normal Surround. And while the 2D surround mode is much more forgiving to the kind of displays being used, when talking about stereoscopic 3D gaming the requirements for building a 3D Vision Surround setup are much more strict. You are required to essentially use three 3D-capable monitors from the same model in order to ensure perfect compatibility and best experience and this is what Nvidia recommends, however sometimes this can be a problem, or you may find a more practical and cost effective way to get a 3D Vision Surround. So what are the options and what will work and what will not, that is exactly what I’ve wanted to test this time trying to use three different 3D Vision-ready displays in a 3D Vision Surround setup and I’ve found out some interesting things that I’ll share with you.

I have multiple 3D-capable monitors available that I use for testing, from different generations and with different features, however I don’t have three exactly the same models to use them as a 3D Vision Surround. It is not that I don’t like 3D Vision Surround, just haven’t gotten to the point in building such a setup for constant use, so far only making temporary setups for testing various things. And since the initial introduction of 3D Vision Surround as a solution Nvidia has greatly improved it and I believe that sooner I’ll have to do a permanent setup for testing. But for now and especially for the purpose of this article I’ll be using three different 3D Vision-ready monitors as this will give me all the possible scenarios to test various things in regards to compatibility between the different displays used for building a 3D Vision Surround setup.

Now, the requirement to use three exactly the same 3D monitors for 3D Vision Surround is based on a few important things. First the external features of the displays are the same – the same size, the same height, the same bezel size and all of this is very importing when you are arranging the three displays to form one big screen together. Then comes the LCD panel used in the 3D monitors, when it is exactly the same it means that you’ll be getting the same color reproduction, level of brightness and response time across all the displays. And specifically for the proper stereoscopic 3D experience there is also the importance of the same level of crosstalk/ghosting you’ll be getting across all the displays and not more on some and less on the other. You should be aware of the fact that even identical models of monitors can have some slight variation in the image they display, so a bit of fine tuning even in this cases can help in getting even better overall experience, making all three displays seem like a one wide display.

So lets see what will happen if we use different 3D monitors inorder to build a 3D Vision Surround setup. I went for three completely different models in size and capabilities, these are: the 23-inch Panar SA2311W, the 24-inch Asus GN245HQ and the 27-inch Asus VG278H. Due to the various sizes of the displays it is really impossible to physically match the three screens in a one seemingly vertically continuous screen – these have different height, not all have height adjustments, different screen sizes, different bezel sizes. But still putting the 27-inch screen at the center and the two smaller ones on the sides does make the setup useable – you still have nice peripheral vision coverage with the two side monitors and your attention is focused on the center display most of the time anyway. The Planar does not have a built-in IR emitter, the Acer has one and the Asus also has it, but the major difference here is that the Planar and the Acer do not support the new 3D Loghtboost technology for ensuring increased brightness levels like on the newer Asus 3D monitor. The 3D Lightboost technology is a monitor technology, but when you use a display supporting it the active shutter glasses also work in a different way than on older 3D Vision monitors that don’t have support for that technology. This essentially should mean that you’ll not be able to make a 3D Vision Surround setup mixing older 3D Vision monitors with models from the latest generation, it should…

So what happens when you connect three different 3D monitors and enable 3D Vision Surround mode? Actually you can do that, even though the drivers will detect that your 3D monitors are different models, as long as they support 3D Vision you can go over the 3D Vision Surround setup wizard and enable the technology. It is a completely different thing however if things will work properly after that in stereoscopic 3D mode, because the 3D Vision detects the first monitor connected as the one being used and assumes that all three 3D displays are the same make and model. So if it is the Planar you will not be able to use anything else besides 3D Vision discover mode, unless of course you plug in an external IR emitter for the glasses, and that happens even though the other two displays actually do have built-in IR emitters. In this situation if you plug-in an external IR emitter and you run something in stereoscopic 3D mode only the Planar and Acer monitors show 3D and the Asus monitor remains blank when in 3D mode. If you connect the Acer 3D monitor first then when you activate stereoscopic 3D mode you’ll see that the Asus will show in stereoscopic 3D mode and the Acer and Planar monitors will show 2D image. If the Asus 3D monitor is connected first the Planar shows the image in 3D mode with a serious level of ghosting and the Acer 3D monitor shows only 2D image, regardless if you use the built-in IR emitter or an external one. So apparently neither of these variants is a good choice, though if you have the center display running in stereoscopic 3D mode and the two side ones show the same image in 2D it is not that bad as actually with your peripheral vision you can hardly get depth information anyway, so it may be a kind of an acceptable compromise (if you rotate your head however things aren’t going to be that good).

The next step was to play a bit with the monitor identification information using different EDID override drivers in order to trick the OS and the video drivers that we actually have three exactly the same 3D capable monitors available and connected, even though they are completely different in reality. Using Planar EDID override driver for all three displays requires the use of an external IR emitter, but the good news is that all three displays actually work in stereo 3D mode and there are no issues with more than usual level of ghosting shown on any of them. It seems that in this case the Asus display does not make use of the 3D Lightboost mode and works in some kind of compatibility mode with the other to displays, the image you get from it is less brighter this way, but it still works properly. Moving to the Acer EDID override driver things get a bit messy using the built-in IR emitter – all displays show stereoscopic 3D image, but only the Asus shows proper image, the other two displays have a lot more ghosting – plugging an external IR emitter however resolves the issue and you get the same good results as with Planar’s ID. And finally using the Asus EDID override driver for all three monitors makes them work in stereoscopic 3D mode, but only the Asus shows proper image, the other two have way more ghosting than usual, regardless if built-in or external IR emitter is being used.

So what is the conclusion of all this testing with mixing and matching different 3D monitors? For best experience you should stick to the recommendation to use three exactly the same 3D monitors, but if that is not an option, then you have a few somewhat acceptable alternatives available as well, but not recommended unless there is really no other choice. Either using the two side displays in 2D mode and only the center one in stereoscopic 3D mode, if the center one supports 3D Lightboost technology. Or going for a some kind of backwards compatibility mode for 3D monitors supporting 3D Lgihtboost technology to work the same way as older models that don’t support the tech, the opposite is not possible however. But these two alternatives are available only if mixing older 3D Vision displays with newer ones that support the 3D Lightboos tech, for example two Acer HN274H with one Acer HN2674H B, making all the three work like Acer HN274H without the 3D Lightboost active for example. If you have only older generation or newer generation 3D monitors with 3D Lightboost support, then things are actually much easier for you, though with serious physical differences matching them in a 3D Vision Surround setup may still not be that good idea.

And here I can now answer that a 3D Vision Surround setup using one BenQ XL2420TX with two BenQ XL2420T monitors should be something that you can make work as these two models are essentially the same with some of the extra features in the TX stripped from the T model, so this way you can save some cash and still get a great 3D Vision Surround setup. Actually starting with drivers version 304 (currently only beta) Nvidia officially allows you to mix different 3D monitors supporting 3D Lightboost without having to resort to any workarounds, so mixing BenQ XL2420TX with two BenQ XL2420T monitors should be working directly with these drivers without the possibility of having issues that may be caused by EDID overrides. Mixing and matching Asus VG278H and Acer HN274H B is also possible with the latest beta drivers, though this may not be that good idea as mixing the two versions of the BenQ that are almost exactly the same. The only problem with being able to mix a BenQ XL2420TX with two BenQ XL2420T monitors in a 3D Vision Surround setup is if you live in Europe for example where the TX version is still not available.
