The DVI specification includes signaling for reducing power consumption. Similar to the analog VESA display power management signaling (DPMS) standard, a connected device can turn a monitor off when the connected device is powered down, or programmatically if the display controller of the device supports it. Devices with this capability can also attain Energy Star certification. Kruegle, Herman (2006). "8". CCTV Surveillance: Analog and Digital Video Practices And Technology. Butterworth-Heinemann. p.268. ISBN 0-7506-7768-6. The DVI connection on the end of the cable may have different amounts of pins depending on the type of DVI connection it is designed for. The different pin configurations are explained below. When Should You Use DVI? Although DVI is considered an older display technology and has connections and ports that look similar to VGA, they’re not the same. One of the biggest differences is the supported signals. Digital video pixel data is transported using multiple TMDS twisted pairs. At the electrical level, these pairs are highly resistant to electrical noise and other forms of analog distortion.
Warning: Although DVI is considered an older display technology and has connections and ports that look similar to VGA, they’re not the sameA DVI-D cable can be used with a DVI-I connector without any problems; it will just read the digital output and disregard the analog. Ultimately, the choice between DVI and DisplayPort comes down to personal preference and the specific needs of your device setup. Is there a difference in quality between Dual-Link and Single-Link DVI?
Unless you’re well versed in the world of connecting computers, monitors, and everything in between, you might not be familiar with some of the essential details such as which cables are necessary to connect all of the key components and which ports to use. In particular, DVI cables are a popular choice for supporting monitor displays. Learn more about DVI cables, and how they differ from some of the other options you might discover when setting up your favorite computer monitor. What is DVI? Warning: DVI is no longer considered the premiere display technology is because it’s limited solely to visual content When DVI was designed, most computer monitors were still of the cathode ray tube type that require analog video synchronization signals. The timing of the digital synchronization signals matches the equivalent analog ones, so the process of transforming DVI to and from an analog signal does not require extra (high-speed) memory, expensive at the time. Did you know that the maximum resolution supported by DVI connectors varies depending on the type of connector? Single-link DVI connectors can support a maximum resolution of 1920×1200 at 60Hz. Dual-link DVI connectors can support resolutions up to 2560×1600 at 60Hz. However, it’s important to keep in mind that there are still limitations to what DVI resolutions can achieve. Terms Apply.

Most flat-panel LCD monitors today include a DVI-D port. Overall, the DVI-D connector is similar to the DVI-I connector except for the absence of the analog portion of the signals.
