Scaler Rate (resolution and refresh rate)

Rotate the Adjust knob while in the Scaler Rate submenu to select one of the available combinations of scaler output resolutions and refresh (vertical scanning) rates. Selecting Lock enables the patented Extron Accu-RATE Frame Lock (AFL™) feature. Accu-RATE Frame Lock eliminates image tearing and other artifacts of scaling motion video by eliminating frame rate conversion. It exactly matches the output rate of the System 7SC’s scaler to the frame rate of the selected input. Select this feature if you will be using motion video sources with a display that is capable of a variety of refresh rates.

The following table shows the available combinations of resolutions and rates.

Scaler Sync (RGB format)

Using the Adjust knob, select the sync format required by the display: RGBHV, RGBS (composite sync), or RGsB (sync on green).

Scaler Polarity (sync polarity)

The display or projector may require a particular combination of horizontal (H) and vertical (V) sync signal polarities. Select the appropriate combination of positive or negative H and V sync by rotating the Adjust knob from within this submenu.

RGB Delay (Triple-Action Switching™)

With Triple-Action Switching, the System 7 switches to the new sync signal before switching RGB (video) signals. That allows the projector to adjust to the new sync timing during a brief delay before displaying the new picture, which will appear without glitches. Triple-Action Switching is also known as video mute switching. Use the Adjust knob to select the blanking period (RGB delay time) from 0 seconds (default) to 5 seconds in half-second steps.

Scaler Blue Out

To aid in setup of the scaler’s color and tint, Scaler Adjust Blue Only can be set to “Yes” so that only sync and blue video signals will be passed to the display. Use the Adjust knob to select this option, which can be used for scaled video output only.
