Precaution for Cables Connection of GPO Display’s Video Wall
31
Digital noise may appear due to poor quality DVI cabling. If the video signal needs be delivered from a distance, electric noise must be accounted for. If the
distance is great or there is a serious noise issue, an optical fiber extender system is recommend over CAT-5/6 extension.
Daisy-chaining can be initiated from any unit. There is no terminator at the end of the unit. It is strongly recommended that installers/customers record the
chaining diagram as it is crucial for diagnosis of issues, should they arise.
Some installation sites have a high level of Electric Noise which may appear onscreen, especially with DVI.
DVI, HDMI and DisplayPort are HDCP-compliant.
Signal-looping specifications
Video signals should be boosted by using a distribution amplifier when more than four (4) units are connected via DVI (NSV & EN-series) or nine (9) units are
connected via HDMI (EK-series) -> See tables below
