DVI-I (integrated, combines digital and analog in the same connector; digital may be single or dual link) DVI-A (Digital Video Interface - Analog): The pin configuration of DVI-A is shown in the picture below. The port only carries analog signals and hence the name DVI- ANALOG. The signals sent by the port are different from VGA and we need a convertor for connecting a VGA monitor to DVI-A port. DVI-A supports video stream of 1920 X 1200 @ 60Hz.
Unified Display Interface (UDI) was proposed by Intel to replace both DVI and HDMI, but was deprecated in favor of DisplayPort. 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.
VGA to DVI
DVI stands for Digital Audio Interface and it was an attempt to create an industry standard for video connectors, a seat which HDMI has now filled. The technology is a little dated, but like VGA, it’s still common on computers, monitors, TVs, and other displays.
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. MicroCross DVI Connector System: Digital Visual Interface Standard" (PDF). Molex. December 2000 . Retrieved 31 January 2023. In December 2010, Intel, AMD, and several computer and display manufacturers announced they would stop supporting DVI-I, VGA and LVDS-technologies from 2013/2015, and instead speed up adoption of DisplayPort and HDMI. [18] [19] They also stated: "Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity". 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. Digital Visual Interface ( DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content.The DVI connector on a device is given one of three names, depending on which signals it implements: An earlier attempt to promulgate an updated standard to the analog VGA connector was made by the Video Electronics Standards Association (VESA) in 1994 and 1995, with the Enhanced Video Connector (EVC), which was intended to consolidate cables between the computer and monitor. [3] [4] EVC used a 35-pin Molex MicroCross connector and carried analog video (input and output), analog stereo audio (input and output), and data (via USB and FireWire). At the same time, with the increasing availability of digital flat-panel displays, the priority shifted to digital video transmission, which would remove the extra analog/digital conversion steps required for VGA and EVC; [5] :5–6 the EVC connector was reused by VESA, [6] which released the P&D standard in 1997. [3] P&D offered single-link TMDS digital video with, as an option, analog video output and data (USB and FireWire), using a 35-pin MicroCross connector similar to EVC; the analog audio and video input lines from EVC were repurposed to carry digital video for P&D. [5] :4 [7] :§1.3.3
To convert DVI to HDMI you’ll need a passive physical adapter. The good news is both DVI-I and DVI-D can be converted to HDMI because they both use digital signals.DVI-I is the integrated format connector. It works with digital and analog equipment, acting as a DVI-D or DVI-A cable, but it won't convert pure DVI-D output to analog. DVI-I has two variations—single-link and dual-link—and has a 29-pin layout to accommodate multiple connections.
HDMI is a newer digital audio/video interface developed and promoted by the consumer electronics industry. DVI and HDMI have the same electrical specifications for their TMDS and VESA/DDC twisted pairs. However HDMI and DVI differ in several key ways.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 ]
