Which factors can negatively affect system performance?

Long cable runs can indeed negatively affect system performance due to signal degradation that occurs over distance. When cables are long, signals can lose strength and quality, which might lead to issues such as lower image resolution or audio clarity, increased latency, and potential interference from external sources. This is particularly evident in analog signals, though it can also affect digital signals. Therefore, careful consideration must be given to the length of cable runs in AV installations to maintain optimal performance.

In contrast, high-quality cables are designed to minimize signal loss and interference, thereby supporting better system performance. Standard resolution is typically a specification that doesn’t inherently reduce performance but rather defines the expected quality; it doesn't contribute to negative performance unless the system is expected to operate at higher resolutions. Thus, while long cable runs present a challenge to system performance, high-quality cables and standard resolutions do not inherently have the same negative impact.
