What is the maximum range for an HDMI connection?

The maximum range for an HDMI connection is typically considered to be around 15 meters under normal circumstances when using standard passive HDMI cables. However, depending on the cables and the environment, using active HDMI cables or extenders can increase the range significantly, allowing connections of up to 20 meters or more without loss of quality. This makes the choice of around 20 meters a more versatile answer for scenarios that utilize specialized cables or active devices.

In standard use cases, HDMI signal quality deteriorates over longer distances, especially beyond 15 meters, leading to potential issues such as signal loss or degradation. Active cables and extenders might utilize signal boosters or different technology to maintain quality, making longer distances feasible. However, standard passive HDMI cables typically do not support connections longer than 15 meters reliably.

The maximum effective range can depend on several factors, including cable quality and the equipment in use, so it's important to consider these factors when planning HDMI installations.
