Does 144hz require dp interface?

144hz does not require the use of dp cable. "DP cable" is a data cable that supports the DP interface, and the DP interface is only one of the 144hz interfaces. The 144hz effect can also be achieved through the HDMI2.0 interface. However, if the display needs to reach 144hz, then the display itself needs to reach 144hz, otherwise it will still not be possible.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Must use "DP line" for 144Hz?

144hz does not require the use of dp cable. This is because the dp interface only supports one of 144hz, and 144hz can also be achieved through the HDMI2.0 interface Effect. Therefore, it is not necessary to use dp cable for 144hz.

"DP cable" is just a data cable that supports the DP interface, and "144Hz" refers to the refresh rate of the screen, which is related to the graphics card (only relative Generally speaking, the refresh rate is a monitor parameter. Taking games as an example, if vertical synchronization is turned on, it is related to the refresh rate), not the data cable. Most computers use data cables such as VGA, DVI, HDMI, etc. This is because the graphics card Or the monitor supports these types of interfaces, and then these types of data cables are used. If the graphics card supports or only provides a "DP interface", then the DP cable must be used, but if it does not support it, there is no need to use it.

However, if you need the display to reach 144hz, then the display itself needs to reach 144hz, otherwise it will still not be possible.

What is "DP line"?

The so-called "DP cable" is a data cable specially manufactured for the "DP interface". Taking computers as an example, the prerequisite for using a DP data cable is that the monitor, computer motherboard or graphics card supports the DP interface. If the motherboard or graphics card in the computer case does not support it or there is no DP interface on the monitor, although you can also use a DP cable, you need to use a DP adapter. Although DP data cables are different from VAG, DVI and other data cables, their uses are the same. Which data cable to use depends on whether the interface of the device supports it. Some devices even provide multiple cables in order to be compatible with other devices. Universal interface.

HDMI2.0 interface introduction:

HDMI2.0 is a high-definition multimedia digital interface standard , can transmit audio and images at the same time. HDMI2.0 supports 4K content transmission, 21:9 aspect ratio, transmission bandwidth 18Gbps, supports dual pictures, and dynamic automatic sound and picture synchronization.

The HDMI standard is the abbreviation of High-Definition Multimedia Interface, which is translated as High-Definition Multimedia Interface. This standard was initiated in April 2002 by Sony, Hitachi, Panasonic, Toshiba and other companies. The biggest feature of HDMI is that it can transmit audio and images at the same time, which solves the problem of separate transmission of video and audio in the previous cable and has been a great success.

Introduction to screen refresh rate

The refresh rate is the number of times the screen is refreshed per second. When watching a movie, what we actually see is Showing a still picture is like showing a slide. Why do we feel that the picture is moving? It is because human eyes have a visual retention effect. The impression of the previous picture in the brain has not disappeared, and the next picture is followed immediately. The picture has caught up, and the difference between the two pictures is very small. One action requires many pictures to be displayed, so we feel that the picture is moving. The replacement of pictures one by one is refreshing. Suppose an The action is completed by 20 pictures, and we look a bit like a cartoon. If the action is increased to 30 pictures, it will look much more natural. This is the refresh rate.

The refresh rate has two categories: vertical refresh rate and horizontal refresh rate. Under normal circumstances, the refresh rate we usually refer to is the vertical refresh rate. It is defined as the number of times the electron beam scans the graphic image on the screen repeatedly.

144hz introduction:

The refresh rate of 144 Hz is a high refresh rate and can also be called a gaming screen. It is recommended in terms of interfaces Choose dP cable for faster transfer rate when playing games. A 144Hz monitor specifically refers to a monitor with a refresh rate of 144Hz per second. Compared with the refresh rate of 60 per second of ordinary monitors, the screen display is smoother. Therefore, 144Hz monitors are more suitable for first-person shooting games where the viewing angle often moves at high speed.
