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.
��DP 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.
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.
