conﬁ guration, do one or more of the following:

Click Restore Defaults and then click Apply.

Disconnect the external house sync.

Viewing the Connection Status

See the section Checking the Connection Status (page 24).

How To Set Up Frame Lock

The following are the basic steps to frame locking several systems. Detailed

instructions are provided in the section Set Up the Hardware (page 17).

Set Up the Hardware

Connect all the systems together using standard CAT5 patch cabling.

Note: WARNING! The voltage and signal on the frame lock ports are different from

Ethernet signals. Do not connect a Frame lock port to an Ethernet card

or network hub. Doing so can cause damage to the hardware.

Set Up the Server Software

Use the NVIDIA Control Panel Synchronize Displays page to

establish the system as the server.

Set Up the Client Software

Use the NVIDIA Control Panel Synchronize Displays page for each

client to enable frame lock on that system and to add an optional delay

to the sync pulse before transmitting to other clients.
