Location 1 in QuantumToolkit:
GraphicsPipeline pipeline = GraphicsPipeline.getPipeline();
for (Screen screen : Screen.getScreens()) {
    screen.setAdapterOrdinal(pipeline.getAdapterOrdinal(screen));
}

Location 2 in D3DPipeline:
for (Screen screen : Screen.getScreens()) {
    screen.setAdapterOrdinal(getAdapterOrdinal(screen));
}

Idea:
Static method inside Screen.

public static void assignAdapterOrdinals() {
    GraphicsPipeline pipeline = GraphicsPipeline.getPipeline();
    for (Screen screen : Screen.getScreens()) {
        screen.setAdapterOrdinal(pipeline.getAdapterOrdinal(screen));
    }
}
