The AV cable, which is responsible for the audio transmission signal, plays an important role in the entire audio system. A good audio cable and a poor audio cable not only have different materials, but also have different internal structural principles. Therefore, there are certain differences in signal transmission performance...

If you can pay attention to the following aspects of the AV cable in use, it will not only improve the sound performance, but also extend the service life of the cable: 1. Cables with different functions cannot be mixed at will, for example, audio cables cannot be used instead...

Disc players can "read codes" and "decode", but in order to reduce costs, their decoding functions are generally relatively primitive. To increase the level of "decoding" and make the sound more beautiful, it is necessary to be equipped with an independent decoder and a power amplifier with decoding function. Optical...

在日常工作和娱乐中，我们离不开电脑、电视、投影仪等设备，而这些设备都离不开各种视频输出接口。如今市面上连接线种类繁多，我们常常搞不清楚何时何地该用哪种线。 市面上最常用的视频线缆有：DVI、VGA、HDMI、DP，它们的传输距离极限是多少？视频线缆可以用于50米的传输距离吗？ 在选择视频线缆之前，我们需要做好充分的准备工作。以下是一份清单，供大家参考，以便朋友们在选择视频线缆时更有针对性。 HDMI线缆 HDMI是高清多媒体接口，是一种高效的全数字图像和声音传输接口，这意味着只需一根HDMI线缆即可同时传输高清视频信号和音频信号。HDMI 2.0支持高达 4K@60Hz Ultr高清分辨率。 市面上的HDMI线缆质量参差不齐，大多数HDMI线缆在传输距离超过10米时都会出现严重的信号衰减。普通铜芯HDMI线缆的最长传输距离约为15米，但通常超过8米后就无法支持4K高清信号。内置信号放大器的HDMI线缆可以传输80米的1080P视频信号，而光纤HDMI线缆则可以传输更远距离的信号。 4K@60Hz vide超过 300 米。 DP线缆 DP接口目前是更先进、更完善的接口，可以牢固地安装在机器上，并通过转换器兼容VGA、DVI和HDMI。DP 1.4版本功能强大，除了垂直同步功能的自适应增强外，还支持60Hz的8K视频。 DP线缆支持 2K@144Hz ultra. 高刷新率。超高刷新率让HDMI、VGA等接口相形见绌，能为大多数玩家带来更稳定流畅的游戏体验。市面上最长的DP线缆一般在10米左右，如果距离过远，性能损失会很大。

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...

��Choosing the right interface will do more with less It should also be noted that some charging ports support the fast charging protocol, and some are general charging, so you can consider your needs when purchasing. Generally, it supports 100W charging, and it only takes 1-1.5h to fully charge the...
