Inventory the longest transmission distance of VGA, DVI, HDMI, and DP cables, it is easy to choose a cable(Part II)
In our daily work and entertainment, we cannot avoid contact with computers, TVs, projectors and other equipments, which are inseparable from various video output interfaces. Nowadays, there are all kinds of connecting cables on the market, and we are always confused about when and where to use which kind of cable. The most commonly used video cables on the market are: DVI, VGA, HDMI, DP, what is their limit transmission distance? Can a video cable be used for a transmission distance of 50m? These questions need to do enough homework before we choose the video cable. The following is an inventory for everyone, so that the friends can be better targeted when choosing the video cable. ③HDMI cable The HDMI is a high-definition multimedia interface, which is a very efficient transmission interface for all-digital images and sounds, which means that only one HDMI cable can transmit high-definition video signals and audio signals at the same time. HDMI2.0 supports up to 4K@60Hz Ultra HD resolution. HDMI 2.1 Cable The quality of HDMI cables on the market varies from good to bad, and most HDMI cables experience severe signal attenuation when the transmission distance exceeds 10m. The longest distance of the ordinary copper HDMI cable is about 15m, but generally more than 8m, 4K HD is no longer supported. The HDMI cable with built-in signal amplifier can transmit 80m of 1080P video, and the optical HDMI cable can transmit 4K@60Hz video over 300m. Compatible with Multiple Devices ④DP cable DP is currently a more advanced and complete interface, it can be firmly installed on the machine, and it can be compatible with VGA, DVI and HDMI through a converter. DP 1.4 version is powerful, along with the adaptive enhancement of the vertical synchronization function, this version supports 8K video at 60Hz. DP 1.4 Cable The DP cable supports 2K@144Hz ultra-high refresh rate. The ultra-high refresh rate makes HDMI, VGA and other interfaces look behind them, which can bring more stable and smooth gaming experience to the majority of gamers. The longest DP cable on the market is generally about 10m, and the performance loss will be great if it is far away. UHD Resolution
