Two types of DVI connectors exist now: a DVI-D connector connected to a video card sends a digital signal, whereas a DVI-I connector may distribute an electronic signal (on LCDs ) as well as an analog signal (on CRT displays).
The DVI-I connector displayed in Figure 1 has more pins than the DVI-D connector displayed in Figure 2. The additional pins are used for analog signals that the DVI d connector will not need.
Difference Between DVI-I and DVI-D
What is DVI?
Let’s start with DVI in the first place.
DVI stands for Digital Video Interface and is a graphical interface used to connect your computer’s graphics card to your computer.
It is one of many connectors (including VGA, HDMI, and DisplayPort) that are available.
The difference between DVI connectors and others can be quickly determined by the plugs of real cord attached with screws (seen on the right).
What types of DVI are there?
In total, there are three different kinds of DVI inputs:
- DVI-D (digital only signal)
- DVI-I (incorporated, both analog and digital signals)
- DVI-A (analog just indication)
Additionally, there are two versions of DVI-D and DVI-I, a single-link version and a dual-link version.
There are five different DVI variations, which are shown below. Most commonly used are DVI-D and DVI-I, while DVI-A is not used nearly as much.
It’s important to remember that none of those DVI cables carry sound, making them useless for speakers built into monitors.
DVI-D vs. DVI-I
What are the differences between a DVI-D and a DVI-I connector?
Physically, DVI-D and DVI-I differ from each other by the number of hooks they utilize. This determines how much bandwidth can be used in the signs and what type they are.
As previously mentioned, DVI-D signals are only digital, whereas DVI-I signals are both analog and digital.
This applies regardless of how many links they have.
For contemporary monitors, such as digital displays, digital signals are used, while for older technologies, such as CRT monitors, analog signals are usually used.
What is the difference between DVI Single Link and DVI Dual Link cables?
The amount of maximum bandwidth that it may use dictates the resolution of the video.
A single-link DVI-D or DVI-I cable may carry 3.96 Gbit/s and, for this reason, is limited to a resolution of 1920 x 1200 on a 60Hz monitor.
Dual-link upgrades the bandwidth to 7.92 Gbit/s for a maximum resolution of 2560 x 1600 at 60Hz. However, it cannot handle 4K.
Two of DVI’s connections, DVI-D and DVI-I, are becoming obsolete and should only be used in the case that HDMI or even DisplayPort is unavailable. DVI is not as high-quality as HDMI or even DisplayPort, which offers better picture quality and performance.
