Anytime a new technology comes along, there are questions. While DVI has been around since 1999, the typical consumer may not be aware of all the details surrounding it. Compatibility varies among types, and then there are things like dual link and single link to make matters even more confusing. An owner's manual is the best way to find out the exact cord you need. However, we've put together a guide to help you navigate the various formats. Digital Visual Interface, or DVI for short, offers an extremely high speed, uncompressed connection between digital TVs, PCs, and other DVI-based electronic devices. The benefit of using this type of cable is the uncompressed transfer of high definition video. Three styles are available. DVI-D is the most common but only transmits high quality digital signals. DVI-A is limited to transferring analog signals and as such is seen mainly on VGA monitors. DVI-I offers the best of both, sending both analog and digital signals simultaneously. Often the initial question is which one do I need? The answer here is fairly simple. Generally, computers use DVI-I while monitors use DVI-D. DVI-D cables can plug into DVI-I ports but the connection doesn't work the other way around. Therefore, you're safest going with a DVI-I to DVI-D or a DVI-D to DVI-D. So what is the benefit of using version "I"? For one, it supports both analog signals via VGA and digital signals, which are used for computer monitors and HDTV's. It can also send signal output to all three types of DVI connectors - I, D, A - by using a matching cable. In short, "I" is compatible with all three as well as VGA, by using an adapter. "A" only works with itself and VGA, with an adapter. "D", as previously stated, works with "D" and "I". And VGA works with "I" by using an adapter. How does dual link fit in? Cables are sometimes described as being either single or dual link connectors. The distinction between the two is resolution. Dual link accommodates higher resolution and therefore a better picture. Single link supports only 1920x1080 while dual link can handle up to 2048x1536. So can you use DVI with HDMI? Single link in the form of DVI-D can project HDMI displays if HDCP isn't active on the source or display. An owner's manual can quickly give you this information. DVI HDCP can communicate with HDMI HDCP in most cases, though compatibility issues are sometimes seen. This will leave you wondering about HDCP. Short for High-bandwidth Digital Content Protection, HDCP works to stop illegal copying of the digital signal. Developed by Intel, HDCP is found in many popular and unpopular cables. It works by stopping encrypted content from being displayed on devices that don't support HDCP or that have been modified to copy content. Overall, DVI offers a faster, clearer signal than traditional cables alone. This is one of those connections that you should take advantage of if you have the opportunity. And while all three support high quality signals, DVI-I is the way to go for extra versatility. Check them out for yourself and get a clearer picture today!
