Resolution and refresh rates

Rotate the Adjust horizontal () knob while in this submenu to select one of the available combinations of output resolutions and refresh (vertical scanning) rates.

Rotate the Adjust vertical () knob while in this submenu to select one of the available refresh rates. Selecting @60L (Lock) refresh rate enables the Extron Accu-RATE Frame Lock™ (AFL™) (patent pending) 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 DVS 204’s scaler to the frame rate of the active input. Select this feature if you will be using motion video sources with a display that is capable of a variety of refresh rates.

Output Signal

Using either the Adjust horizontal () or Adjust vertical () knob, select the output video format required by the display: RGB (default), YUV, or RGsB.

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 either the Adjust horizontal () or Adjust vertical () knob.

If the previous output signal was specified as RGsB or YUV, this submenu will not be displayed because this menu is only active for RGBHV.
