A single DVI link consists of four twisted pairs of wire (red, green, blue, and clock) to transmit 24 bits per pixel. The timing of the signal almost exactly matches that of an analogue video signal.

DVI (Digital Visual Interface) is an older type of video connection. While it is not obsolete just yet, it is on its way there. Like DisplayPort, DVI only supports video and not audio. DVI is also bulkier, does not support 4k like HDMI or DisplayPort, and is a bit more complicated as there are different versions of it.

The cables are roughly the same price as HDMI. DisplayPort can also carry audio. The video signal over DVI is basically the same as HDMI. The maximum resolution potential depends on the equipment, though.

HDMI to DVI As mentioned in the description of the DVI to HDMI device, DVI and HDMI use the same digital video format for the video. This means that if you are only using the video signal you can simply use an HDMI to DVI plug adapter or cable that simply changes the physical connections.

DVI: Video only, perfect for older systems or for 144Hz at 1080p. DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.

D-Sub is currently the most widely used monitor interface, compatible with very large numbers of PCs and LCD monitors. ... To use a dual-link DVI-D connection, the DVI-D input on the LCD monitor side, the DVI-D output on the PC side, and the DVI-D cable must all be compatible with the dual-link DVI-D standard.

When used as a monitor interface, a D-Sub port is also known as a VGA port, an analog connection standard that's been around for some time. The connector is a DE-15 connector with 15 pins in three rows, often referred to as a "mini-D-Sub 15-pin" or "D-Sub 15-pin" connector.

DVI to HDMI DVI is a digital signal in the same format as the video portion of HDMI. The difference is that DVI doesn't carry the audio signal like HDMI does. This means that if you are only using the video signal you can use a simple DVI to HDMI plug adapter that changes the physical connections.

VGA is essentially obsolete. So are most analogue signal/cables. DVI is already on the way to obsolete, especially DVI-I (which could be used to produce VGA with a simple adapter). Modern graphics cards tend to have HDMI and/or DisplayPort.

Image Quality Differences DVI ports send and receive a digital signal directly from the computer that does not need to be converted and does not suffer image quality drops. DVI ports can update on-screen content faster than RGB VGA because there's no time lost in the conversion process.

As well as its notable visual advantages, HDMI can transfer audio signals, something DVI is unable to do. That means streaming a video from one device to another only requires one cable with HDMI; with DVI, you also need to account for audio cables.

DVI-A cables will work with both DVI-A and DVI-I connectors. Male DVI-D cables may fit in a female DVI-A connector, but will not work as they do not carry any analog signals.

DVI. The DVI, or Digital Visual Interface, connection is starting to die out, although it is still on every graphics card. The video signal is basically the same as HDMI, just without the audio. ... Single-link cables and hardware support up to only 1,920×1,200 resolution, but dual-link DVI supports 2560×1600.

3 Answers. Connecting HDMI output to DVI input is not straightforward due to HDMI carrying an HDCP-protected signal. Monitors that don't have an HDMI port are not HDCP-compliant, hence can't display an HDCP-protected digital signal.

DVI was purposely developed and designed to transmit video signals. In comparison, the D-sub connector is used for a much wider variety of applications. ... DVI is capable of transmitting both analog and digital signals its D-sub equivalent (the DE9) only carries analog signals.
