What configuration is required to play 4K videos smoothly? In order to solve this problem, the editor summarizes this article on 4k video today, hoping to help more friends who want to solve this problem to find a more simple and easy way.

We know that 4K video is a new height compared to standard definition video and high definition video (HD), and 4K resolution belongs to ultra high definition resolution. At this resolution, viewers will be able to see every detail and close-up in the picture. If the cinema uses 4096 × 2160 resolution, the audience can clearly see every detail of the picture no matter where it is in the cinema.

The 4K resolution means that the value of each row of pixels in the horizontal direction is up to or close to 4096, regardless of the frame ratio. According to the range of use, 4K resolution also has a variety of derivative resolutions, such as 40963112 of Full Aperture 4K, 36562664 of Academy 4K and 38402160 of UHDTV standard, which all belong to the category of 4K resolution.

Such a high resolution inevitably requires larger data storage and higher-performance display devices. The amount of data of 4K resolution video is four times that of ordinary high-definition video (1080p), so it also needs four times the amount of data to store and four times the amount of bandwidth to transmit, and also has higher requirements for playback equipment.

4K TVs are decoded and displayed by dedicated decoding and display chips, which can ensure the smooth playback of 4K video.

Computer equipment is different. CPU and graphics cards will also do other operations in addition to display. To play videos smoothly, it is recommended that the main accessories be configured as follows:

CPU:9 Intel Core i5jie 4 core, 8MB cache; graphics card: larger than 2GB memory, such as NVIDIA ®GeForce ®GTX 1650 4GB disk: because to tell read data, low-speed disk will cause video stutter, it is recommended to use solid state disk or tell hard disk.

This configuration is the current mainstream home computer configuration, can meet 1-way 4K video playback and 2-way 1080p video playback, if playing multiple channels at the same time will not be able to achieve.

For some surveillance projects, if you want to play multi-channel high-definition video at the same time, the configuration should also be improved as needed. The efficiency of the network card will affect the delay of the video, although it is a gigabit network card, it will still have a significant impact on the delay of high-definition video.

If you want to broadcast online, in addition to the terminal system to meet the requirements, streaming media server system is also an important source of performance.

After reading the above, do you have a general idea of the configuration needed to play 4K videos smoothly? If you want to know more about the content of the article, welcome to follow the industry information channel, thank you for reading!
