![]() Step 1: Plug one end of your DVI cable into your source device’s DVI port, hand-screwing it in place with the locking screws to ensure a secure connection. Audio Cable (depends on which ports are available).Let’s learn how to extract audio from your DVI-I, DVI-D, and DVI-A source device using an optical/SPDIF/Toslink, 3.5mm, or RCA audio cable. audio cables) to extract the DVI-compatible source device’s audio. That said, you will need to use a separate connection (i.e. Whether a DVI to HDMI connection can carry audio will depend on which adapter you use, with some natively supporting sound and others not. You can use the following cables to transmit audio for your DVI-to-HDMI setup.ĭoes a DVI to HDMI Connection Carry Audio? Additionally, the necessary cables are usually quite affordable. While this means you will have to purchase and connect additional cables, the entire process only takes a few seconds. Does DVI Carry Audio?Ĭonsequently, you will need to use separate audio cables to transmit sound. On the other hand, dual-link cables use dual TMDS transmitters, which increases their max resolution to a whopping 2560×1600. True to its name, single-link cables use a singular TMDS transmitter and support a max resolution of 1920×1200. Meanwhile, dual-link cables have more pins and use 24 of them during the transmission process.Īll DVI cables use transition-minimized differential signaling (or TMDS for short). Single-link cables have fewer pins and only use 12 of them when transmitting video. This difference not only affects the way the port looks (see diagram above), but it also affects the speed at which the signal is transmitted as well as the video quality. Single-Link vs Dual-LinkĭVI-I and DVI-D cables can be either single-link or dual-link. This is because the video must go through the digital-to-analog conversion process, slightly reducing the final quality. While the video quality is still high, you can expect it to be slightly lower than the video transmitted via DVI-I and DVI-D cables. DVI-Aįinally, DVI-A cables only support analog signals. This digital-only cable transmits high-quality video signals and supports better connectivity since it bypasses the digital-to-analog conversion. This means it can connect two digital or analog sources, but not one of each. ![]() This nifty cable transmits both analog and digital signals, though it does not act as a converter for the two. What are DVI-I, DVI-D, and DVI-A Cables? DVI-I Refer to the diagram below to find out which DVI port your source device has. There are five different types of DVI ports, each one’s contact pins varying in size and number. Which DVI to HDMI converter you’ll need to use depends on the type of DVI port your source device has.
