3Dfury is a Very Powerful and Flexible 2D/3D Video Converter Box

February 1st, 2012 · 12 Comments · General 3D News

An interesting new device is going to be soon available called 3Dfury from the same people that make the popular HDfury products… actually 3Dfury is the new fourth generation of HDfury. This device should be able to convert your 2D only display into a 3D-capable one, or add support for HDMI input to a display that support HDMI or even digital input for that matter, and you can also add HDMI 1.4 input capabilities to a 2D or 3D display that does not have the interface available. There is not much information about the conversion of 2D displays into 3D-capable ones, but this would mean your 60Hz capable product will be able to output with 30Hz per eye for example, so still good for 3D movies, although not that great for gaming in stereo 3D mode. 3Dfury should be able to work with either Digital (DVI-D/HDMI) or Analog (RGBHV/component) displays as well as with Dual Projectors setups for displaying 2D or 3D content. The device features a single HDMI 1.4 input (DVI compatible) and can output in either digital HDMI/DVI or analogue VGA output, or even both at the same time, but since it is HDMI-based no support for Dual-Link DVI. The 3Dfury has built in support for all the standard 720p and 1080i/p 3D input resolutions in frame packaging, Top/Bottom and Side by Side formats and the device can output in 720p60, 720p72, 720p96, 720p120, 720p144 Frame Sequential; 720p and/or 1080p for 60Hz displays; 1080p60, 1080p72 (currently in development). You can also use two 3Dfury devices to build a dual projector 3D setup with up to 720p 240Hz for use with passive 3D glasses, for all other 3D setups active 3D shutter glasses are required. There are also some extra features for when using the device with 2D content such as the double and triple framerate from 24Hz 1080p material resulting in 1080p48 or 1080p72 output as well as the 720p120 – double framerate from 720p60 source that is currently in development. There is also full support for HDCP, so there should be no trouble watching protected content such as Blu-ray or Blu-ray 3D movies with this device, and you can create custom EDID parameters for your display device.

The 3Dfury has a standard VESA Stereo Connector in the form of a 3-pin mini-DIN Sync Out port to allow the connection of an external emitter and use of active 3D glasses with the device when playing back stereo 3D content. If you are using DLP-based device you should be Ok without an emitter with the help of DLP Link active shutter glasses, but for all other (besides dual projector passive 3D setups) you would need to connect an IR or RF-based emitter and use a compatible glasses with it. There are 3D glasses and an RF emitter that are going to be sold by the makers of 3Dfury specially for use together with the device and while there is not much information about them it is possible that these glasses will be made by BitCauldron. As the specs for the glasses kind of remind what the ones being branded by Monster Cable and Optoma RF glasses and being produced by BitCauldron offer, so if my guess is right and if you already have some pairs of these they will be the perfect match for the 3Dfury. But even if I’m not right the active shutter glasses made by BitCauldron should also work just fine as their RF emitter has support for use with devices using VESA Stereo connector. An interesting thing about the glasses being offered for use with 3Dfury is the fact that the user has control over the Duty cycle and Delay and can also invert the left/right image, some features that may help a lot at times.

According to the information available the device has less than one frame of latency per second added to the signal which should be barely noticeable in the form of input lag and that is very important for gamers. Of course, although the time it takes for the device to process the signal isn’t much, if you already use a display with a lot of input lag, then you may still have a problem as there is no way to reduce the lag of the display by using 3Dfury. With that said the 3Dfury is more targeted at multimedia use and not that much at gamers as gamers would usually prefer to go for display solutions that can offer 1080p with 120Hz refresh rate or 1080p 60Hz 3D mode and since the 3Dfury is based around HDMI 1.4 it is somewhat more limited. The device has a USB port and the firmware can be upgraded, meaning it can get extra features added over time, so new resolutions and formats for example could be introduced as well in the future.

The price of the 3Dfury is $399 USD and it is currently available only for pre-order with the first pre-orders expected to start shipping on 15th February, so in about two weeks time, and after that it should be available for normal orders. The RF emitter offered by the company making 3Dfury will cost you $49 USD and a single pair of active shutter glasses for it another $99 USD. You can say the price is a bit high, but the device definitely offers some interesting and useful features that might be able to save you from buying much more expensive hardware. But let us see how things will turn out when 3Dfury gets released and if it will indeed offer all that is being promised and work as good as it should. The HDfury already has a very good track record, so the expectations from 3Dfury are also quite high already and it is to be expected…

Alternative 3D Vision-compatible Shutter Glasses from 3DTV Corp

May 4th, 2011 · 10 Comments · GeForce 3D Vision

The company 3DTV Corp is a maker of more affordable “generic” 3D active shutter glasses for different 3D-capable products and they apparently also offer alternative glasses for 3D Vision as well… or more precisely said compatible with 3D Vision. The 3DTV Corp shutter glasses model NV1 pictured above with orange frames are available for $68 USD. They should be compatible with the Nvidia IR emitter and work with 3D monitors and 3D projectors (3D laptops may or may not be compatible, there is contradicting information) that have the infrared emitter either built-in or connected externally, so you can use them as an extra pair that comes cheaper than Nvidia extra pair of glasses only. The glasses should also be compatible with DLP Link 3D HDTVs and 3D DLP projectors as well as other devices that do come with the standard 3-pin mini-DIN VESA stereo connector (Nvidia Quadro cards for example) by using an additional 3DTV Corp GEN2 Emitter. Have in mind that these glasses are cheaper for a reason and in order to make them more affordable, their maker decided to go for the use of a standard single use CR2032 battery instead of a rechargeable lithium-ion battery. The operating range is up to 10 meters according to the manufacturer.

The other more interesting offering from 3DTV Corp is their 3D Window PC-RF Kit that uses an RF (radio) emitter instead of IR (infrared light) for communicating with the shutter glasses. This kit is also compatible with Nvidia’s 3D Vision, but it does not need the IR emitter, apparently the bundled RF emitter in the kit is emulating the infrared emitter effectively replacing it. This kit including the RF emitter and a pair of glasses is available for $125 USD, and here the glasses use a rechargeable battery and they actually look more like the original glasses from Nvidia. Having RF emitter instead of IR one means that you get up to 15 meters, no direct line of sight is needed anymore and you should not have interferences with other infrared devices. The RF emitter also has support for plugging into standard 3-pin mini-DIN VESA stereo connector, making these radio glasses compatible with other 3D devices as well.

Have in mind that I have not personally tested these two types of alternative glasses and that you should be careful as some of the non-original shutter glasses that claim 3D Vision compatibility actually do have some trouble and can give you a lot of headaches. So anyone that actually has tried these glasses is more than welcome to share feedback on how well they work and how they compare to the original shutter glasses from Nvidia!
