Product Information

Some DVI-D sources use non-standard extensions to output HDMI signals including audio (e.g. ATI 3000-series and NVIDIA GTX 200-series). [17] Some multimedia displays use a DVI to HDMI adapter to input the HDMI signal with audio. Exact capabilities vary by video card specifications. Although DVI is present in most modern day graphic cards and HD monitors it is gradually being phased out. At present HDMI is preferred over DVI and HDMI is also being preceded by USB-C. But for few years we will see DVI in our life. DVI-I port is the most popular one of all the three types of DVI connectors and is used for connecting High Definition displays to the PC. Since it can run video stream at 2560X1600 pixel (with refresh rate of 60Hz), the user can experience high definition gaming and movie experience. Some DVD players, HDTV sets, and video projectors have DVI connectors that transmit an encrypted signal for copy protection using the High-bandwidth Digital Content Protection (HDCP) protocol. Computers can be connected to HDTV sets over DVI, but the graphics card must support HDCP to play content protected by digital rights management (DRM).

If a depth greater than 24 bits per pixel is desired, the least significant bits are sent on the second link. One of the purposes of DVI stream encoding is to provide a DC-balanced output that reduces decoding errors. This goal is achieved by using 10-bit symbols for 8-bit or less characters and using the extra bits for the DC balancing. In addition to digital, some DVI connectors also have pins that pass an analog signal, which can be used to connect an analog monitor. The analog pins are the four that surround the flat blade on a DVI-I or DVI-A connector. A VGA monitor, for example, can be connected to a video source with DVI-I through the use of a passive adapter. Since the analog pins are directly compatible with VGA signaling, passive adapters are simple and cheap to produce, providing a cost-effective solution to support VGA on DVI. The long flat pin on a DVI-I connector is wider than the same pin on a DVI-D connector, so even if the four analog pins were manually removed, it still wouldn't be possible to connect a male DVI-I to a female DVI-D. It is possible, however, to join a male DVI-D connector with a female DVI-I connector. [12]DVI-I (integrated, combines digital and analog in the same connector; digital may be single or dual link) People are often constrained by the ports available on their computers. Older PCs may only have a VGA port and new monitors may only have a DVI port. In such cases you may need a VGA to DVI adapter to connect this PC and monitor. However, DVI-D will require an active adapter, something like this one. The good news is DVI has a pink for +5V so these adapters can take the power they need directly from the device without needing an external power supply, like VGA to HDMI adapters need. Overall, converting DVI to other connector types is very easy with inexpensive adapters.

As mentioned earlier the pin configuration of three types is different and you have to match the appropriate cable connection or the port will be damaged permanently. Do not assume all DVI cables are exchangeable and connect a DVI-A plug to DVI-D port and vice versa. You need to connectDVI-A plug to DVI-A port only and similarly DVI-D connectors. As for DVI-I it can take both DVI-A and DVI-D cable. Manchester, Gary (October 7, 1996). "Molex PnD intellectual property letter" (PDF). Archived from the original (PDF) on February 22, 2003.However, DVI-I and DVI-D are still found on monitors and computers. I won’t be talking about DVI-A in this article because it’s rarely used today. As I mentioned earlier, DVI and VGA are dying standards, but they still have some practical uses. DVI-I is good because it can support modern resolutions (1080P at 60Hz) and you can easily convert it to other connector types. Most analog connectors, such as VGA, require active adapters to convert to HDMI, but you don’t need that with DVI.

Generalized Timing Formula (GTF) is a VESA standard which can easily be calculated with the Linux gtf utility. Coordinated Video Timings-Reduced Blanking (CVT-RB) is a VESA standard which offers reduced horizontal and vertical blanking for non-CRT based displays. [15] Digital data encoding [ edit ] The maximum resolution on a DVI-D dual link is 2560×1440 at 60 Hz, the same as the DVI-I dual link resolution. You can also convert VGA to DVI because DVI supports analog signals too. Do remember that only DVI-I supports both analog and digital, DVI-D only works with digital, so you’ll need an active adapter to convert that to another type of connector.

Retrieved 2022-07-14.DVI-D single link has the same bandwidth as DVI-I single link, so the maximum resolution is the same at 1920×1200 at 60 Hz. DVI-I Dual Link has a maximum resolution of 2560×1440 at 60 Hz. You can push it higher but you’ll have to lower the Hz rate to 30 which is a little clunky.
