HDMI DVI D-SUB RJ45

With its standard upgraded from 2.0 to 2.1, HDMI is now the most popular audio and video interface in the video and audio market, covering televisions, PC, monitor, mobile phone and other fields. The substantive differences between HDMI2.0 and HDMI2.1 is the broadband: HDMI2.0 has a transmission bandwidth of 18Gps, while HDMI2.1 has a transmission of 48Gps. And the improvement of bandwidth can directly lead to the increase amount of transmitted data. Besides, HDMI2.0 can not support the transmission of 8k video, while HDMI2.1 can support not only 4k video transmission with 120Hz, but also 8k video with 60Hz.

DVI transmit digital signal. Digital image information will be directly transmitted to the display without any conversion in the transmission process, so it can save time by reducing the traditional cumbersome process of digital-analog-digital, and thus its speed is faster. Besides, using DIV to transmit data can not only maintain the signal of the data, leading to a purer and more realistic color in the display, but also effectively eliminate smear and jamming in transmission.

A VGA interface is a 15pins trapezoid also named as D-line interface, which mainly used for analog signal transmission. Although VGA interfaces will lead to a relatively low display effect and a loss of display signal, VGA interfaces were widely used in the early applications. Display effect remains low even when DVI interface is used to analog VGA signal. If the VGA’s workmanship and materials of wire rod are poor, the computer screen is prone to color deviation, water ripple and drag shadow. Therefore, VGA is more suitable for low resolution screens.
