Spatial View’s 3DeeScreen Will Turn Your 2D Laptop Into a 3D One

November 11th, 2011 · 5 Comments · GeForce 3D Vision

The company Spatial View has been offering their addon called 3DeeSlide for iPod Touch 3rd Generation and iPhone 3GS, iPhone 4 and the latest iPhone 4S for a while now, making these mobile devices’ 2D displays into stereoscopic 3D ones. And you don’t need to wear any kind of glasses as the adapter makes your screen an autostereoscopic 3D one, at the cost of reduction of the 2D resolution. This of course requires you to also get specially optimized content in the form of 3D videos and 3D photos, but Spatial View also has their 3DeeCentral – a website offering stereoscopic 3D content not only for the devices equipped with the 3DeeSlide adapter, but for other 3D-capable viewing solutions as well. Unfortunately the 3DeeSlide won’t make your iDevice capable of playing stereoscopic 3D games.

But Spatial View is now making things bigger, by introducing their 3DeeScreen product that does to your laptop what the 3DeeSlide does to your iPod/iPhone device – turns the display into an autostereoscopic 3D one using custom designed lenticular lens filter. The 3DeeScreen goes one step further by also adding eye tracking, using your laptop’s built-n webcam in order to provide better experience in 3D. And as the smaller mobile version, the bigger one intended for 15.6-inch laptops is designed for watching 3D movies and 3D photos, there is nothing about being able to play games in stereo 3D mode with it (although it might be possible with the help of software such as the iZ3D driver or the TriDef 3D Ignition). Regarding movie playback, and especially Blu-ray 3D movie support, the device should also be supported by ArcSoft’s TotalMedia Theater and CyberLink’s PowerDVD software video players, so you should be well covered. Spatial View’s 3DeeScreen is designed to work on most standard 15.6″ laptops with 1080p and 720p resolution displays and to be easy for installation and removing when you don’t need it (uses magnetized mounting frame).

List of Currently Supported and Verified Models:

– Asus G53J with 1080p display
– Asus N53J with 1080p display
– Dell Studio 1558 with 1080p display
– Dell XPS L502 with 1080p display
– Dell Studio 1557 with 720p display
– Dell Inspiron 1564 with 720p display
– Dell Inspiron N5010 with 720p display
– HP Pavilion DV6 with 720p display

Of course there are probably a lot of other laptops from different brands that will work with this addon, with the important thing being the fact that you need a standard 15.6-inch display in order to be able to use the 3DeeScreen. The product is expected to begin shipping on November 21st and Spatial View is already accepting pre-orders for $89.95 USD with the normal price of the product set at $129.99 USD when it launches. It sounds almost like a DIY solution to turn your normal laptop into a rival of the Toshiba’s autostereoscopic 3D mobile computers Qosmio F750 and F755. So you may want to keep an eye on this product and look for some reviews when it comes out, I might be able to also do a review after it is released…

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.

Review of the 27-inch Asus VG278H 3D Vision-ready LCD Monitor

November 7th, 2011 · 94 Comments · GeForce 3D Vision

Asus VG278H is just the second 27-inch 3D Vision-ready monitor that is going to be available on the market this month around the world, it is a model that we’ve been waiting for quite some time now and it is finally here. The previous 27-inch model compatible with Nvidia’s 3D Vision technology was released earlier this year and it was Acer HN274H that I’ve also reviewed and liked a lot. So the Asus was not only a bit late, but also already has a good performing competitor on the market that it needs to beat in order to take the position of the best 3D Vision monitor on the market so far. But the Asus VG278H is up to a good start, it comes with integrated IR emitter and bundled with the new 3D Vision 2 glasses as well as with support for the new Nvidia 3D Lightboost technology that is promising a brighter image in stereo 3D mode. It also has HDMI 1.4a interface with support for stereoscopic 3D input with various other S3D-capable devices, but only frame packaged input. It seems that the company has also learned from some of their previous mistakes with the first 3D Vision-ready monitor they’ve had, the VG236H and the new 27-inch model is not with a glossy screen. So I started testing the monitor with very high expectations and it has managed to respond very well to most of them, but there were a few things that I was a bit disappointed with. Generally speaking however I really liked the performance and features that the 27-inch Asus VG278H 3D Vision-ready LCD monitor has, but let me get into more details starting with the official specifications…

Asus VG278H Monitor Specifications:

Panel Size: 27″ (69 cm) Wide Screen 16:9, TN, LED backlight
Native Resolution: 1920×1080 pixels
Pixel Pitch: 0.311 mm
Brightness (Max.): 300 cd/m2
Contrast Ratio (Max.): 50,000,000:1 (dynamic)
Viewing Angles (CR>=10): 170° H / 160° V
Response Time: 2 ms (GtG)
Video Inputs: Dual-link DVI-D, VGA, HDMI 1.4a
Power Consumption: 65W On, <1W Sleep, <1W Off/Standby Integrated Audio: 2x 3W stereo speakers Monitor stand: tilt +15°~-5°, swivel and height adjustment Dimension (WxHxD): 643 x 460 x 220 mm Weight: 8 kg.

One thing that I found interesting in the new Asus VG278H monitor is the fact that the infrared emitter for the 3D glasses, located at the top of the display is placed in an adjustable “box” that you can rotate in order to better fit to your specific style of use of the monitor. And together with the highly adjustable stand of the monitor you get more flexibility when setting up the display (higher/lower positioning or near/far usage scenarios). I also want to focus your attention on the fact that the manufacturer specifications of the display state 300 candelas per square meter maximum brightness, similar to the specs of the 27-inch Acer 3D monitor, but when measuring the actual brightness I get readings for much higher brightness levels… and the 3D Lightboost technology is not responsible for this, but I’ll get back to the brightness level a bit later on. Another thing that caught my attention in the standard specifications of the Asus VG278H is the relatively high power consumption the monitor has and that made me measure the actual power consumption. It was like that: around 45W with 60Hz refresh and around 50W with 120Hz refresh rate in 2D mode, and switching to 3D mode between 30W and 40W, depending on the setting of the Lightboost technology (Off – MAX). It is interesting to see how the Lightboost technology affects the power consumption and what are the brightness levels per eye and with different settings for the Lightboost, but that is something that needs further investigation and I’ll post about at a later time.

The OSD menu of the monitor has the option to control the level of the Lightboost technology as well as to completely disable it which is a good thing to have in order for me to test and compare different settings. Visually the difference between the setting with Lightboost to off and to the maximum does not seem that big, you can certainly notice that there is difference in darker areas of the image as they seem brighter, but it is hard to tell if the image is actually twice as bright or less than that. I’ll focus on measuring that in a separate post as I’ve already mentioned, so stay tuned, the important thing is that you really get brighter image in stereo 3D mode thanks to the Lightboost technology and it really looks better than on older 3D Vision-ready displays, especially in games with darker environment. When using the 3D Lightboost technology you can say that the experience you get in 3D and the level of brightness now seems to be almost like what you get with a good 3D HDTV, something that was really needed as an improvement for 3D Vision.

Now, moving on to the color accuracy and brightness of the display. Here I’ve got interesting results, measuring the default color accuracy that the display offers as well as the level of brightness and these results kind of reminded me of something. The level of brightness is 427 cd/m2 which is way over the 300 cd/m2 advertised by Asus and by pushing the monitor to the maximum I was able to get 450 cd/m2 as a maximum brightness level. And considering that the level of brightness is quite high, you can even visually notice that as image on the monitor looks really bright even with the naked eye, it is expected to also not have very accurate color reproduction, although only the gamma level was a bit off as yo can see.

After doing a calibration of the monitor, and getting some of the brightness reduced, the color accuracy becomes very good with a brightness level a bit below the 300 cd/m2. Now, what I see in images for both before and after the calibration are results that seem very similar to these from Acer HN274H monitor, although the brightness levles are a bit lower. This has made me start thinking that it is not impossible that the two monitors are based on the same 27-inch LCD panels from LG, although the Asus monitor comes with support for 3D Lightboost technology… or at least that LG may have further developed the same LCD panel by adding support for the Nvidia tech to it. Unfortunately as I could not get to the service menu of the monitor I’ll have to open the monitor to be able to confirm this suspicion and this is something I cannot do at the moment.

One thing that is different here however, when comparing the Asus monitor to the Acer is the level of input lag I was able to measure. One thing that I’ve noticed immediately after getting the Asus VG278H monitor for testing is the good responsiveness I’ve got from it, although I’m not overly sensitive to input lag. After measuring it I can confirm that the Asus is better than the Acer in that aspect, although the VG278H is not totally lag free, the input lag at the default factory settings is very low… something very close to 0 milliseconds and less than 5 ms for sure. So even if you do not plan to use this monitor for gaming in stereo 3D mode (although you get it ready for that with 3D Vision glasses and IR emitter bundled), but instead plan to use it as a 120Hz gaming display in 2D mode (non-stereoscopic 3D), then you should be quite satisfied with the very low level of input lag that you will be getting.

Here is how the backlight uniformity of the display looks like, no serious backlight bleeding, apart from the slightly brighter top and bottom of the display (the blue color). There is some slight variation that is more easily noticeable if you look at the display at a high angle, but normally when you look directly at it you can hardly see anything non-uniform apart from the slightly brighter top and bottom pars of the display. Of course the the backlight uniformity can vary from unit to unit, but generally you should not be expecting to get serious issues with backlight bleeding on this monitor.

Now I’m going to start with the usual tests for crosstalk/ghosting as this is still one of the most serious issues that the makers of 3D displays need to deal up with in order to be able to deliver the best user experience in stereo 3D mode. I’m using a set of specially selected tests to get idea about the performance you should expect as well as to compare to other products that I’ve already tested. All of the following tests are performed with the standard factory settings of the display, so be aware that there is a possibility to get better results and performance if you tweak the monitor a bit in the OSD menu. So now moving to the extreme crosstalk test photos, as expected some crosstalk is still visible with both the white and black. Again very similar results to the 27-inch Acer monitor, although the brightness here is higher and the crosstalk is slightly lower, so there is some improvement, but I expected to see more. Especially after seeing some presentations about the new 3D Vision and 3D Ligthboost technology that were talking about “ghost-free” images. But lets us move on to the more actual usage scenarios to compare the levels of crosstalk/ghosting as these specially made test photos are showing ghosting even on good 3D HDTVs.

Next is the sailboats stereoscopic 3D test video, a real world crosstalk test to show the level of crosstalk/ghosting you can expect from a 3D video. Slightly visible crosstalk if you pay enough attention to it, if not you may not notice it at all.

Going to the game Tomb Raider: Underworld for one more crosstalk check in a real world game, there still some faint ghosting present at the top of the screen and there is also some color ghosting at the bottom. Again very similar to what could be seen with the Acer HN274H 3D monitor. A very important thing here is that all of the above crosstalk/ghosting tests were made at the factory default settings for the monitor, so it is what you get when you open up the monitor and start using it. But you should be well aware that with some tweaking of the default settings you can get even better results without having to compromise much of anything.

So can you do something about reducing the crosstalk and make things better? Yes, you actually can do something and that is to reduce the contrast of the monitor a bit from the default setting of 76 in stereo 3D mode to about 55. Thanks to the significantly increased brightness due to the 3D Lightboost technology you can sacrifice some of the brightness levels in order to get rid of most of the annoying crosstalk, although not to have it completely gone, while still getting quite bright image. Actually I’m wondering why didn’t Asus decide to do this as a factory default as it really works well and leaves only hardly visible traces of crosstalk that won’t bother you like for example the color ghosting that is easily visible with the default setting and is really annoying.

But what is the conclusion in terms of the crosstalk/ghosting with the new Asus HN278H 3D Vision-ready monitor? Personally I’ve expected more from it right out from the box and what we get is just slightly reduced ghosting level with the factory settings as compared to the Acer that was released a few months ago. However, as I’ve already explained you can get even better results with manually tweaking the settings. The Asus VG278H is definitely a move in the right direction, but we need the crosstalk/ghosting reduced more in order to get better stereoscopic 3D experience and apparently Asus has decided to focus more on the higher brightness level than on reduced ghosting and they could’ve done a better balance with the out of the box settings, fortunately you are free to do it yourself. Another thing that I have kind of expected is some improvement in the non-PC 3D support, the new Asus monitor also works only with HDMI 1.4 frame packaging, just like all other 3D monitors with HDMI 1.4, but there is still no support for Side by Side and Over/Under input modes and this limits the usability of the monitor with other 3D-capable devices. With that said I can say that I’m actually very happy with the monitor, even though you need to play a bit with the settings to really get the best results in terms of crosstalk reduction, the brightness increase in stereo 3D mode is really good. The improvement of the brightness level in stereoscopic 3D mode was the other thing that was really needed and we got it and it is working well in order to improve the user experience. And all this when combined with the new 3D Vision 2 active shutter glasses that come with bigger lenses, block better the external light and come with a more comfortable design is another good improvement. Adding the very low input lag of the Asus monitor things are looking good not only for stereo 3D gamers, but for people willing to use the high refresh rate more and not for gaming in stereo 3D mode. So if you are looking for a new 27-inch 3D gaming display then the Asus VG278H should be your primary candidate, and if 27-inch is too big for you, then you should wait a bit more for the smaller 24-inch monitors with 3D Lightboost support (as a must have feature) to start coming out on the market very soon. And you can expect some more interesting things from me about the Asus VG278H monitor in the next few days as there is a lot of extra testing and comparison going on…
