HDML wall plates are designed to pass through signals without degradation
and should not significantly impact the signal quality. However, it is possible
for the quality of the transmission to be influenced by factors related to distance
between devices, cable quality, electromagnetic interference, and other
environmental factors. In general, choosing high-quality cables, well-designed
wall plates and avoidance of sharp bends can help to minimize any impact
on the signal. Additionally, regular testing and maintenance of your setup
can help to ensure that signal degradation is minimized.
