QuestionWhy do I need a converter for some types of connections while I can just get by with adapters for others?

AnswerConnections that can be made with adapters are signals that tend to be basically the same but just use different types of connectors. For instance, HDMI and DVI share the same type of digital video signal so one can be adapted to the other easily. However, HDMI and VGA use completely different formats. One is a digital binary signal whereas the other is an analog sin wave signal. A device that can real one signal and actively convert it into the other format is needed in this situation.

QuestionCan I go from HDMI to VGA (or visa versa) by combining an HDMI/DVI adapter with a DVI/VGA adapter?

AnswerNo. While DVI-I connectors have pins that support digital and pins that support analog, these pins are not connected to each other because of the reason explained in the preceding FAQ. Top of Page



QuestionAre all DVI connectors the same?

AnswerNo, there are several different types of connectors for DVI. While they are similar, different connectors will have different number of pins. Top of Page



QuestionWhat are the different types of DVI Connectors?

AnswerThere are several variations of DVI as well as derivative connectors based on DVI that have been used by different manufactures. However, the most commonly found versions found today are as follows. DVI-I carries both analog and digital signals. DVI-I can be single link or dual link. DVI-D carries digital signals only. DVI-D can also be single link or dual link. DVI-A that carries only analog signals. It does not have a dual link option. M1 P&D that carries analog and digital signals as well as USB serial information. Top of Page

QuestionWhy don't you carry a DVI-D dual link to HDMI adapter or cable?


AnswerWhile both DVI and HDMI are each able to handle extended bandwidths, they do it in different ways. DVI uses a dual pipe connection where as HDMI simply increases bandwidth on the existing lines. So while they are compatible with each other in single link, HDMI does not connect with DVI on the dual link pins. You can still connect a dual link DVI device to HDMI. The devices will configure themselves appropriately, but be limited to single link speeds which still support 1080p. Top of Page



QuestionIf I connect HDMI to DVI, will I still get audio?

Answer
No. You'll need a separate audio connection. Top of Page



QuestionWhat is HDCP?

AnswerHDCP stands for High-bandwidth Digital Content Protection. It is a digital rights management technology used by content providers such as movie studios to protect their media property from being illegally distributed. Top of Page



QuestionWhat is the difference between Mini-DVI, Mini-VGA, Mini-HDMI and Mini-DisplayPort?

AnswerEach connector is a miniaturized version of their standard sized counterpart. Each has a unique connector and one will not fit in the place of another. You must use the correct connector for the type that exists on your device.Top of Page



QuestionWhat's the difference between DisplayPort and HDMI?

AnswerDisplayPort was primarily designed as a replacement for VGA, DVI and LVDS which are common interfaces used in the computer/IT industries, while HDMI was developed by the Consumer Electronics Industry specifically for Home Theater applications. Toward this end, DisplayPort has certain enhanced features such as direct drive monitor design and single cable multi-function monitor connectivity. Some advantages of HDMI are the ability to support xvYCC color, Dolby TrueHD and CEC (Consumer Electronics Control) signals. Though both share powerful A/V features, DisplayPort was designed to complement HDMI, not to replace it. Top of Page
