LG C1 48寸，hdmi 2.1原来用的传统铜线，也是个大牌子，2米的将近200块。
这次某牌光纤2.1线2米只要不到300，换上后明显觉得画面更清晰锐利，尤其是看文字，那种锐利感很明显，然后色彩更饱满，感觉亮度上也有所提升，应该是对比度更高的缘故。
以后高端显示设备我只用光纤线了。
这么多人没有用过，或者看不出来，我就当当好人上个对比图吧，原图太大了，找不到合适的图床，即使是压缩了还是可以很明显看到区别。
要是你说没区别，恭喜，省钱了。

再贴个国外的测试

双盲测试，10人里面有10个选光纤的画面更好。
Fiber delivers better color depth, brightness, and contrast, a more faithful copy of the original signal.
Copper is prone to electromagnetic interference (EMI). Stray EMI in our homes is rampant from all our wireless devices and copper cables pick it up like an antenna. This interference is seen as noise in the picture, a grainy effect that’s not present in the original content. When you see a side-by-side comparison of copper versus fiber at as little as five feet of distance, the effects of resistance and noise are clearly distinguishable. If you’re fussy about things like this like I am, you want to get it right.
简单来说，铜不仅仅是距离长了信号会损失，短距离也会受到电磁干扰导致失真。
