Many custom installers use Wireworld HDMI cables simply because they work in situations where others don’t. All current Wireworld HDMI cables are certified by DPL Labs to exceed the 18Gbps required for every feature of HDMI2.0. Even though HDMI video is generally excellent to begin with, a faster and quieter cable can still reduce pixel noise, improving contrast, color saturation and depth. On the other hand, HDMI audio tends to be very lossy, making the cables connecting source components to the receiver/processor the most important audio cables in the system. Therefore, we recommend upgrading the source cables as the first step to appreciating the benefits of Wireworld HDMI cables.
