What is the cost of upgrading a PC system from DVI to HDMI?
There are several options. The lowest cost would be to add a basic PCI Express HDMI Graphics card for approximately US$100. Higher end graphics cards, however, can offer better performance in certain applications. For example, for around $US400, manufacturers are offering a high-end graphics card with built-in processing power so that as the user watches a movie, for example, he or she can also use the processing power of the computer to do other work. The processor on the graphics card is doing the required processing to play the movie, leaving the PC’s CPU free to perform other applications. As well, some graphics cards have their own audio controller and do not require an external S/PDIF input. If you intend to use your PC to render video on a large TV, make sure your HDMI graphics cards incorporates high-quality video processing. ATI Avivo™ or nVIDIA’s PureVideo™ HD2 technology are two such offerings from these companies.
