What is the difference of monitor outputs

monitor Outputs

To connect the monitor to the computer can be used by one of the currently existing interfaces (DVI, D-SUB (VGS), HDMI, DispleyPort), depending on which one is available on the monitor.

Deal with what is better to use, you can only understand how they differ.

Input VGA (D-SUB 15)

One of the first interface for connecting a computer andmonitor which transmits an analog signal in RGB color scheme with a frequency sweep signals horizontally and vertically. This interface is designed for use in a cathode-ray tubes monitors. Predominantly blue connector has 15 contacts arranged in three rows. Each row is offset with respect to adjacent so that the contacts are arranged in staggered rows. connector housing has a trapezoid shape in order not to confuse the orientation of the mating connector when connected. Connector called D-SUB, while the VGA defines signal format. The LCD monitor can be found this way out, but in terms of efficiency it concedes digital.

DVI Input

Digital input monitor, which was developedalready for flat-panel monitors with matrices, in which each pixel is represented by a separate fixed element. The connector has a rectangular shape with beveled corners on one side and two separate groups of contacts. The main group - 24 pins arranged in 3 rows, a smaller group - a 4-pin, located in the side and separated by a slot, which is also a lock.
The DVI input is designed to receive the digital signalthe video card. Meet the CRT monitor with a DVI input is unlikely to succeed. The interface was designed specifically for use in LCD monitors, plasmas, and other similar devices, where it is possible to transmit video signal from the matrix without any additional changes. In order not to confuse and not to insert the connector of the connecting wires are not the party provided the bevels on one side of the connector and an extra slot of the lock on the side of the main groups of contacts.

DVI connector and can transmit analog signals (DVI-A, DVI-I). For each of the possible connections there are separate leads and adapters. It is important not to mix them up when connected.

HDMI Input

Connector, which appeared in the course of further developmentdigital interfaces for monitors and other multimedia equipment. The main feature of this input is the ability to transfer not only the digital video signal and sound. Connector itself flat, rectangular shape, inside which there is a tongue with the contact pads on both sides. For orientation mating connector on the connecting cable provided specific slants to one side of the connector. Bevels is not straight, but slightly rounded, concave inside the connector.

With an HDMI interface can connect multiple monitors or a monitor and combine, for example, home cinema.

Login DisplayPort

Connector coined to format almost similar toHDMI, slightly different data rate and the shape of the connector. The form of his rectangular flat. Lock corners are chamfered with one of the short sides. Externally, the latter two types of connectors are the same size, but the presence of a completely different locks will not be allowed to mix them and insert the connecting wire is not that format.
