In order to eliminate video processing delay associated with frame rate conversion, it is recommended that you lock the LED-PRO to the input source frame rate, using this function. Following are descriptions of each menu function:

•Mode — enables or disables the Lock to Source mode.

Important

When Lock to Source is enabled, LED-PRO does not allow you to switch input channels. You can only switch to/from the current input channel and the Black/Logo channel.

•Type — selects the Lock to Source type. The choices depend on the selected mode. If the mode is disabled, the type is n/a. The available types are:

~V Lock — vertical lock only. This mode is always available for all input and output resolutions.

~HV Lock — both horizontal and vertical lock. This mode is available only if the input and output V Totals are the same.

•H Phase — allows the output H timing to be adjusted relative to the Lock to Source mode. Please note:

~

This selection is n/a when the type is set to V lock.

The range is +/- one-half the H Total.
