The first Guangzhou International Radio, Film &Television Exhibition and 4K Television Technology Exhibition were held in China Import and export commodity trading exhibition hall. Shenzhen Hangalaxy present the real 4K technology for professional audiences at home and abroad playing by 4K TV, 4K player and Hangalaxy brand 4K 100 meter HDMI optic fiber transmission system.
During the test, Hangalaxy 4k 100M HDMI optical fiber transmission system works perfectly on 4k (4096X2160) at 60Hz,4:4:4 without equalizer, ultra HD high speed, error free data transmission, zero attenuation, no delay, no signal loss in high noise environment.

The following test adapts D&Q brand 55 inch 4k smart TV and Hangalaxy brand fiber HDMI2.0 cable.
As you can see when we use 100m Hangalaxy HDMI2.0 transmission cable, the resolution will be 3840X2160@60Hz（4K）.But if use 10m old(copper) HDMI cable, the resolution only reach 1080P 30Hz,as copper cable frame rate is only 30Hz,so that’s why sometimes you can see surging screen when there is a mobile phone nearby. There is a video link for reference. But pls note that the picture and video appears on screen is not a one-to-one copy of the original signal. Overall brightness and contrast do not match the original.

Good equipment must be a professional cable. Let’s tell you why?
We can think transmission cable as a road, audio and video signals are cars, the copper HDMI cable is a two-way 2 lanes, and the optical fiber HDMI cable is a two-way 8 lanes. The higher resolution requires bigger transmission data. That’s why the 4K HDR needs higher transmission bandwidth than ordinary 4K. Similarly, YUV4:4:4 and 10bit improve the picture, But also require high bandwidth. If it is the 4K HDR 60p10bit signal source, or YUV4:4:4, and the transmission distance is over 20-30M. I believe many ordinary HDMI cable on the market can’t work well, because the signal data is too large, it will cause data traffic jam, in order to transfer the signal, the original signal will automatically reduce the color to 8bit or even lower. If the signal amplifier is adopted, although the transmission distance can be solved, but it is easy to burst the screen and damage the equipment. Fiber is the way to go for very good technical reasons: 18 Gbps is fast, but the speed of light is faster.
So it’s time to check your infrastructure equipment, and take a close look on fiber optic HDMI cable, it will give you amazing performance. Hangalaxy brand HDMI optical fiber transmission system cable will be your best choice.
