Eyefinity Display Group Status -From Extended to Clone

Question asked by nareshsankapelly on May 2, 2013

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;




          lpDisplayMap->iDisplayMapValue = ADL_DISPLAY_DISPLAYMAP_MANNER_CLONE;

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




                                                              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.
