The Monitor Equalizer allows the observation of another view, potentially made of multiple segments, in a different channel at a different resolution. This is typically used to re-use the rendering of a large-scale display on an operator station.
The monitor equalizer adapts the frame zoom of the output frames used to observe the rendering, depending on the destination channel size. The output frames are downscaled on the GPU before readback, which results in optimal performance.
The figure above shows a usage of the monitor equalizer. A two-segment display wall is driven by a separate control station. The rendering happens only on the display wall, and the control window receives the correctly downscaled version of the rendering.
