Sync Filter is designed for using UTP CAT5 cabling.

Sync Filter level adjustment is to add the sync stability, but not adjust picture quality or

eliminate skew.

Since different brand monitor have different setting, so there is no recommended setting.

Please adjust the level based on picture stability. If no picture display or picture not stable,

then please use STP cable.

Caution:

1. The wiring must be away from electro magnetic equipment, i.e. microwave, wireless, hi voltage

cable…etc.

2. The maximum distances supported by the VGA Extender are dependent on the type of twisted pair

cable and image resolution of the PC’s VGA interface. Make sure that the maximum

recommended operational distances have not been exceeded.
