6. S-Box Installation and Connection
• S-BOX Connection (Service Port)
The Service port is a dedicated monitoring port used to access the OSD menu during initial installation of an S-Box and
①
check the playback status of a source device.
The resolution for the Service port is FHD (1920*1080 @ 60 Hz).
②
If a source device with a UHD resolution is connected to an S-Box, screen flickering may occur or a corrupted screen
③
may be displayed. This issue is caused due to 2:1 downscaling of the Service port with no specific scaling algorithm and
has nothing to do with the actual LED cabinet screen display.
[Caution!] This port is for service use only and has no function for the user. Do not connect any cable to this port.
