If you have an AMD-based video card that has support for the AMD HD3D Technology (Radeon HD 5000 series or newer) you can take advantage of the promotion that DDD is currently running for their TriDef 3D software and get a license for half the normal retail price. With the help of the TriDef 3D software you can convert games into stereoscopic 3D format for playing on compatible 3D-capable monitors or 3D HDTV sets, as well as play 3D photos and 3D videos on your 3D-cabled PC. Have in mind that this discount will be valid until the end of this month (November 30th), so you should take advantage of that offer now and not wait for the last moment and possible miss your chance. What you should be well aware of however is that by getting the discounted license for the TriDef 3D for AMD HD3D software you will be able to run it only on compatible AMD graphics, so if you replace your graphics card with an Nvidia-based one at a later time you will not be able to use the software on it! The TriDef 3D software has a 14-day trial version available that you may download and try before you decide if you should buy a license for the software.
