Set the signal source to be output by HDMI; if it still doesn't work, check the HDMI cable and interface.
HDMI fiber optic cable is specifically for high-definition audio and video equipment and the development of the transmission interface. Therefore, he for the interface, wire, connector, production process to put forward a higher level of craftsmanship requirements. So that the transmission of high-definition digital signals can be stable and quality assurance. All of the above factors are the cause of the price difference between HD cable and fiber optic cable.
The SIG HDMI cable 8k resolution, ultra-clear high-speed transmission effect, worth having. Fiber optic HDMI cable application range is even wider, fiber optic HDMI cable has been done in line with HDMI2.0 standards, can directly transmit 4K @ 60FPS ultra-high definition signals and is not affected by the distance, can be applied to the need to output high-definition image display equipment and large-area cabling to connect a variety of occasions, the application field can be described as a very wide range of applications, such as: home theater systems, remote information distribution systems, broadcasting control systems, public *** security and high-definition HDMI cable, HDMI cable is the most popular and most widely used in the world. The application areas are very wide, such as: home theater systems, remote information distribution systems, broadcasting and television control systems, public **** security high-definition monitoring systems, high-definition video conferencing office systems, multimedia systems, large-scale medical imaging systems, industrial automation systems and so on. Fiber optic transmission is subject to less interference, more conducive to the transmission of high-definition picture, while HDMI copper cable line because the transmission process of copper wire will produce interference, attenuation, electromagnetic radiation and other undesirable phenomena, interference itself.
