The difference between the input and output interfaces of the graphics card and the display interfac

Choose the graphics card first,Most graphics cards are connected to the display with dual interface design24-pin digital signal interface and 15-pin analog signal interface,There is also an HDMI output input interface,When you connect to the current display,You can buy an adapter as needed。

HDMI port on the computer, which is the HDMI output port (used to connect to a TV or monitor, etc.).

HDMI also supports uncompressed 8-channel digital audio transmission (sample rate 192kHz, data length 24bits sample), as well as any compressed audio stream such as Dolby Digital or DTS, as well as 8-channel 1-bit DSD signals used in SACD. In the HDMI specification, support for ultra-high data volume uncompressed audio streams such as Dolby TrueHD and DTS-HD has been added.

All interfaces on the graphics card are output interfaces and cannot be used as inputs, and there are 4 common interface types for computer graphics cards: VGA, DVI, HDMI, DP.

1. Because the VGA interface is an analog signal, it inevitably causes the loss of some image details, and is only suitable for displays below 20 inches;

2. If the display adopts a resolution of 1920*1200 or less, DVI-I, DVI-D, HDMI, DP interfaces are acceptable, and the screen size has little impact;

3. If the display adopts ultra-high resolution, such as 2560*1600 or a multi-screen display output system, dual-channel DVI-D, HDMI, DP can be competent;

4. If you use a 3D display, under the resolution of 1920*1080, DVI-D, HDMI and DP are not too problematic, if it is more than 2560*1600, it is best to use HDMI and DP output interfaces.

HDMI is the output interface, all the interfaces on the graphics card are output, and the input is the display, that is to say, the graphics card outputs the picture to the display display, it's as simple as that.

Output, of course! The function of the graphics card is to transmit the signal of the computer host to the display, so all the interfaces on the graphics card are output, and the input interface is only available on the display device, and the graphics card is not a display device.

Display graphics card HDMI output must be output No input.

Of course it's output, otherwise how can you make the display show something, the display is input.

The HDMI connector on the graphics card is output and is used to connect the TV and projector.

is output.

It can be connected to LCD display, LCD TV and other display output devices through HDMI cable.

HDMI on the graphics card is the output, the host is the signal source output device, and external monitors, TVs and other devices display the host content.

Today's graphics cards generally have many output interfaces, HDMI, DVI and VGA interfaces1 can be connected to external display devices with different interfaces.

2 It can be connected to several display devices with different interfaces at the same time to display the same content.

3. It can be connected to several display devices with different interfaces at the same time for expansion and multi-screen display.

1. The input devices of the computer include keyboard, mouse, camera, etc.

2. The output equipment of the computer has a monitor, printer, audio, etc., and the graphics card is used to connect the monitor, so the data is from the graphics card to the display, which is the output interface.

3. The input interface of the graphics card is a gold finger.

Dear, the graphics card is a display processing transmission, so the interfaces on the graphics card are outputs.

output, behind the display is the input.

Most of the computer equipment is the output port, and the display device is mostly the input port.

The graphics card only has an output, and the input is the slot where the graphics card is inserted.

is output.

The graphics card provides graphics processing computing power, and it is finally processed and used to feed back to the display device for display, so the input is useless, and the output can be provided to an external display for display.

It needs to be output to a monitor.

The computer needs to install a capture card to input signals, such as capturing PS4 images for live broadcasting.

The role of the graphics card is to evolve the screen to be displayed into data that can be processed by the display, and then transfer it to the display through the data cable and display the picture by the display.

The graphics card does not need to receive any picture-related data from the display.

The model, performance and other signals of the display need to be transmitted back to the computer through a data cable.

Based on this information, it can be judged that the HDMI interface on the graphics card can be output or input.

Commonly used display interfaces.

It is one of the most common interfaces in daily life, and is used in many ** devices in the home.

and audio interfaces are configured on most monitors.

HDMI port on your computer.

Among them is the HDMI output port (used to connect to a TV or monitor, etc.).

HDMI also supports uncompressed 8-channel digital audio transmission (sample rate.

192kHz, data length 24bits sample), as well as any compressed audio stream such as Dolby Digital or DTS, also supports the 8-channel 1-bit DSD used by SACD. In addition to the HDMI specification, uncompressed audio streams such as Dolby TrueHD and DTS-HD have been added to the HDMI specification.

The standard Type A HDMI connector has 19 pins, and a Type B connector that supports higher resolution has been defined, but no manufacturer still uses the Type B connector. The Type B connector has 29 pins, allowing it to send extended ** channels to meet future high-quality requirements, such as WQSXGA (3200x2048).
