    Eyefinity Display Group Status -From Extended to Clone

    nareshsankapelly

      I am trying to enable eyefinity. For that first I want to switch from extended to Duplicate Display Group Status. For switching from EXTENDED mode to DUPLICATE mode first I am using ADL_Display_DisplayMapConfig_Get to get the display targets and display maps and then I am setting iDisplayMapValue of display map to ADL_DISPLAY_DISPLAYMAP_MANNER_CLONE but there is no change in the display Mode. Following is the code snippet.

       

                if (ADL_OK != ADL_Display_DisplayMapConfig_Get( lpAdapterInfo[iCurrentAdapter].iAdapterIndex,

                                                                                                                                                  &iNumDisplayMap, &lpDisplayMap,

                                                                                                                                                  &iNumDisplayTarget, &lpDisplayTarget,

                                                                                                                                                  ADL_DISPLAY_DISPLAYMAP_OPTION_GPUINFO ) )

                          {

                                    PRINTF("ADL_Display_DisplayMapConfig_Get() failed\n");

                                    iReturnValue = FALSE;

                                    break;

                          }

       

                lpDisplayMap->iDisplayMapValue = ADL_DISPLAY_DISPLAYMAP_MANNER_CLONE;

               if(ADL_OK !=  ADL_Display_DisplayMapConfig_Set(          lpAdapterInfo[iCurrentAdapter].iAdapterIndex,

                                                              iNumDisplayMap,

                                                                    lpDisplayMap,

                                                                     iNumDisplayTarget,

                                                                    lpDisplayTarget           ))

              {

                  PRINTF("ADL_Display_DisplayMapConfig_Set Cloning Desktops failed\n");

              }

       

      I am not getting what I am doing wrong here. Any help, suggestions are appreciated.

      Thanks
