Extron electronic DSC HD-3G A Resolution, 23.98 Hz, 24 Hz, 25 Hz, 29.97 Hz, 30 Hz, 50 Hz, 60 Hz

•Output Resolution — This option lets you select the resolution and refresh rate for the connected output display. The DSC HD-3G A has a range of factory-loaded resolutions and rates from which to choose (see the resolutions table below for the available resolutions and rates. Different refresh rates are available depending on the selected resolution.

1.Select Output Resolution from the Output menu.

2.Press the  or  button to select a resolution.

3.Press the  or  button to select a rate for the resolution.

4.When you enter a new resolution, a message appears on the display, prompting you to press Enter to confirm your selection. If you do not confirm it within

15 seconds, the scaler returns to the previously selected resolution and rate.

The following resolutions and rates are available for the DSC HD-3G A:

Resolution	23.98 Hz	24 Hz	25 Hz	29.97 Hz	30 Hz	50 Hz	59.94 Hz	60 Hz

•Genlock/AFL — This option lets you enable or disable syncing of the video signal to the reference signal from an external sync device connected to the Genlock Sync input connector. Signals on the green wire of a component video device or an SDI genlock signal can be used for genlock.

This option also enables and disables the AFL (Accu-RATE Frame Lock), which locks the output vertical refresh rate to the vertical refresh rate of the selected input.

NOTE: Genlock and AFL lock the output refresh rate to similar input rates. If the input signal is locked on a rate that is not considered a standard SDI output or that is very different from the current output setting, the DSC may not output a signal. The image may not display or may blink.

To select the genlock or AFL mode, select Genlock/AFL from the Output submenu, then press any of the arrow buttons to step through the options. The choices are:

•Off: The output runs at the selected output frame rate using time base corrected frame buffers. This selection is the default.

•Input AFL: The output is locked to the vertical sync of the input. This is valid only if the frame rate is an SMPTE video standard and the output frame rate is the same.

•SDI Genlock: The genlock input and loop-out are used for sync reference. The Genlock input supports bi-level and tri-level sync. The video output requires time base correction if the input source is of a different frame rate.

•SDI Genlock Offset — This option lets you adjust the horizontal and vertical offset of the genlock signal. (This feature can be adjusted only if the DSC is set up for SDI genlock.)

Use the  or  button to adjust the horizontal (H) offset value. Use the  or  button to adjust the vertical (V) offset value.
