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.

3. All wiring is “straight-through” twisted pair cable, not being used for other LAN or telephone
equipment.
4. Do not connect the VGA Extender to a telecommunication outlet wired to unrelated equipment.
