FST was created to improve the inherited lengthy HDMI authentication process, based on the HDMI and HDCP specifi cations. FST provides quicker A/V source switching and greatly improves the overall A/V system behavior and performance when more than one HDTV display is used in the system setup.
WALL MOUNTING INSTRUCTIONS The GefenToolBox 1:4 Splitter for HDMI should be mounted vertically in a wall or cabinet with wood/drywall screws as shown in the diagram above.
