LG’s Dual Play Feature to be Available on LG Cinema 3D HDTVs

September 2nd, 2011 · 9 Comments · Other S3D Tech

At the IFA trade show LG is all about 3D technology and even their theme is “DO IT ALL IN 3D”, however one of the interesting features they are demonstrating seems to be getting less attention that in deserves (LG are probably a bit to blame for that as they are not releasing a lot of details about it yet). I’m talking about LG’s Dual Play feature that they are showing with a racing game and Xbox 360 console – essentially using the 3D features of the LG Cinema 3D TVs to show two different views in 2D to two persons playing a game in multiplayer mode. This probably already reminds you about the upcoming Sony PlayStation 3D monitor and the SimulView technology it will have to allow pretty much the same thing on LG’s 3D TV sets and Xbox 360 consoles. The approach however is a bit different for these two, since Sony uses active shutter glasses and LG passive, although they both rely on the 3D capabilities of the displays. And the end result is a nice to have extra feature that Sony will initially support on the PlayStation 3 console and the PlayStation 3D monitor only and it may require extra optimizations to ensure compatibility with specific games. With the LG implementation demonstrated on an Xbox 360 console the end result should be pretty much the same, although the quality may be a bit lower as compared to the active solution that Sony will provide…

The Dual Play feature has to turn a split screen multiplayer game into two separate views each of them seen only by the first or the second player, but not just any game that has split-screen multiplayer mode will do. Have in mind that each player must wear passive glasses with matching polarizing filters, so instead of the left and right filters with different polarization that are typically found in each pair of glasses, each player will wear a pair with either two left or two right lenses getting the same image with both eyes. And you can get to use that extra feature without actually having to get anything special, you can even swap the lenses on two pairs of normal polarized glasses that you got with the LG Cinema 3D HDTV and get the required Left/Left and Right/Right pairs of glasses. Then all you have to do is activate a game’s multiplayer mode (compatible with that function) that will split the screen in two and then set the TV to use this Dual Play function. You may think that it should also work by just manually activating the Top/Bottom or Side by Side 3D input and you will get two different views for each player, but you are forgetting that for this to work you need to send squashed frame output and with multiplayer split screen you get the full frame that is just cropped to fit your part of the screen, meaning that if you try to do that you will get a distorted frame. So if you thought that this extra function would be possible on all passive 3D HDTVs, then you will have to think again as things are not that simple as they may seem. But we’ll have to wait a bit more until LG releases more details about which of their 3D HDTVs will support the Dual Play functions and what other requirements will be there besides the more specific glasses…

Be Careful With the 3D-capable LCD Monitors Supporting HDMI 1.4a

February 11th, 2011 · 26 Comments · Other S3D Tech

Acer is the first company that already has a 3D-capable LCD monitor with support for stereo 3D over HDMI 1.4a and this is the model Acer HS244HQ (it uses only HDMI) and will have two more models that will have stereo 3D support over both Dual-Link DVI and HDMI 1.4a – the Acer GN245HQ and Acer HN274H. This for a lot of people automatically means that they would be able to replace the need of a 3D HDTV with one of these 3D LCD monitors, but this is not entirely true. You should be for example able to connect any 3D-capable device that outputs stereo 3D content using the frame packaging method defined in the HDMI 1.4(a) specification such as a PlayStation 3 console. But you will not be able to use an Xbox 360 console in 3D mode with games that do have native stereoscopic 3D support with the reason for that being the fact that the Xbox 360 can output stereo 3D in various formats, but not in the frame packaged format. Usually the Xbox 360 uses Side by Side output and that is something that you can manually switch from a 3D HDTV, but not from the any of the mentioned above monitors as the do no have built-in support for any of these additional modes. So again, a word of warning when you are planning what to buy – a 3D HDTV or a 3D-capable monitor with support for HDMI 1.4a, based on what you are going to use it for…

Crysis 2 Will Support Stereo 3D Mode on Xbox 360, PlayStation 3 and PC

June 15th, 2010 · 7 Comments · Stereo 3D Games

Good news coming from EA about the upcoming First Person Shooter Crysis 2 that is expected to be available by the end of the year. During a press conference at E3 Expo Electronic Arts has announced that the game will support Stereoscopic 3D mode not only on the PC, but also in its console version available for Xbox 360 and PlayStation 3 and this probably means native S3D support built-in the game engine, as Xbox 360 still does not offer any official Stereo 3D support on console level, unlike the PS3 and PC. Unfortinately still not a lot of details are being disclosed, but we’ll probably get more details with the game nearing its official release date that still hasn’t been announced yet…

“At Crytek, we always strive to raise the technology bar. As the 3D revolution sweeps movies and television, we are excited to bring Crysis 2 to 3D, making it the first big action game to be available in true stereoscopic 3D,” said Cevat Yerli, CEO and President of Crytek. “The 3D experience represents a quantum leap in interactive entertainment. With all of the same story and action seen in the 2D version of the game, the 3D version adds another dimension of intensity and immersion to the action.”

Whether played in 3D or standard 2D, Crysis 2 drops players into a devastated New York in the midst of an attack by a frightening alien species. The alien enemies are armed with deadly weaponry and exceptional sensory abilities that test players’ skill and push them to the limit. These terrifying invaders stalk the streets of New York, leaving the streets in chaos and the skyline in flaming ruin. Surrounded by catastrophic destruction, players harness the superhuman abilities of the Nanosuit to level the playing field, becoming the ultimate weapon on a mission to save New York.

Now, considering the fact that first Crysis games was one of the most demanding titles for your hardware when it was first released, so we can expect to get the same from Crysis 2 too, especially when played in stereo 3D mode. And when talking about that I’m referencing the PC version of the game, as with the console versions it will most likely be a bit stripped down from advanced graphical effects and features in order to be able to provide good performance even in stereo 3D mode. So you better start thinking about upgrading your PCs CPU and GPU from now if they are not yet up to date… ;)
