I don't know if you've ever encountered it,Connect a slightly longer HDMI cable,There will be a lot of picture noise、Flickering and other puzzling problems,This is because the HDMI signal is transmitted in the process,The signal is interfered or attenuated,Coupled with long-distance transmission debuff,Image clarity and stability will be on the next level。
In order to avoid HDMI signal attenuation, Xiaochi will disclose the information of the following three treasures for friends: HDMI cable, HDMI extender, and graphics card equipped with HDMI Retimer technology.
Direct connection: cable transmission.
In the case of not using external equipment, a more convenient way is to use a cable to directly connect to achieve the purpose of extending the signal.
1. HDMI extension cable.
In a small space environment, HDMI extension cable can be said to be a cost-effective extension method. Traditional HDMI copper cables, mainly according to the core of the transmission distance to determine the transmission distance, low-quality cables may appear noise and other problems, while high-quality cables can generally ensure 15-20 meters of high-definition signal transmission distance, relatively affordable, favored.
2. HDMI optical fiber cable.
HDMI fiber optic cable seems to have no disadvantages except for being expensive. The optical fiber cable is not only light in weight and resistant to bending, but also comes with a photoelectric module chip, which adopts optical signal transmission, which can extend the signal transmission to the level of 100 meters, and the attenuation is very low, which can ensure the clarity of the picture and the realism of the sound, and is suitable for the occasion of high-definition image display equipment and large-area wiring connection.
2. Find an intermediary: extender transmission.
If you want to build a professional application scenario and need long-distance one-to-many, or many-to-many high-definition signal transmission, HDMI extenders are a more sensible choice.
1. HDMI network extender.
Using HDMI network extenders, HDMI output signals can be extended to 50-200 meters, this kind of extenders are usually used in pairs, front and back two ports, front HDMI interface, reverse RJ45 network interface, through the network cable, router transmission, can achieve a pair.
One-to-many signal extension. Compared with copper wire, its transmission distance is longer, and compared with fiber optic cable, it is more affordable.
HDMI Fiber Optic Extenders.
When transmitting HDMI high-definition ** monitoring or splicing large screen display and other scenarios, if the transmission distance exceeds 120 meters, the ordinary extender will have mosaic, color distortion and other problems at this time, HDMI optical fiber extender was born for this, its bandwidth is large, the signal is more stable, and the transmission distance can be increased to the kilometer level, but it is generally used as a professional signal transmission system such as multi-** teaching.
3. New ideas: HDMI Retimer graphics card.
In addition to the above two methods, the 20th anniversary graphics card launched by Shadowrun this year also provides new ideas for extending the HDMI transmission distance.
The 20th Anniversary graphics card is the industry's first graphics card equipped with HDMI Retimer technology, thanks to the Spectrum PS8419 chip, this technology starts from the source, amplifying and reconstructing the HDMI signal of the display source, so as to improve the strength and quality of the signal, so as to ensure that the HDMI signal is still stable and high-definition under long-distance transmission.
Not only that, the HDMI Retimer technology equipped with the Filmrun graphics card is also suitable for multi-display, long-distance signal transmission and high-demand professional application scenarios, which can bring users a more stable and high-quality visual experience.
In addition, the 20th anniversary graphics card of Yinglax equipped with this technology will be added to a new member in the near future, please wait and see
