Hi,
I think the only way is to query the eyefinity configuration. This will provide you enough information to determine which display is located and which position of the eyefinity group. You can have a look at the eyefinity sample that comes with ADL. Please take a look at the function atiEyefinityGetConfigInfo. On a high level I would recommend you to enumerate through the Adapters, find the mapped displays. On a mapped display get the SLS configuration. This will give you the total resolution of the group and the X position and the Y position of the display inside the group.You will get the SLS coniguration by calling ADL_Display_SLSMapConfig_Get. This function will return you the ADLSLSTargets. Each display in a group has its own entry in this array and provides you the Adapater index, the display index and the position of the display in teh group.
The code could look like this:
// Determine how many adapters and displays are in the system
ADL_Adapter_NumberOfAdapters_Get(&nNumAdapters);
if (nNumAdapters > 0)
{
pAdapterInfo = (LPAdapterInfo)malloc ( sizeof (AdapterInfo) * nNumAdapters );
memset ( pAdapterInfo,'\0', sizeof (AdapterInfo) * nNumAdapters );
}
ADL_Adapter_AdapterInfo_Get (pAdapterInfo, sizeof (AdapterInfo) * nNumAdapters);
// Loop through all adapters and search for genlocked displays.
// Only on those a window will be created.
for (int i = 0; i < nNumAdapters; ++i)
{
int nAdapterIdx;
int nAdapterStatus;
nAdapterIdx = pAdapterInfo.iAdapterIndex;
ADL_Adapter_Active_Get(nAdapterIdx, &nAdapterStatus);
if (nAdapterStatus)
{
LPADLDisplayInfo pDisplayInfo = NULL;
ADL_Display_DisplayInfo_Get(nAdapterIdx, &nNumDisplays, &pDisplayInfo, 0);
for (int j = 0; j < nNumDisplays; ++j)
{
// check if display is connected and mapped
if (pDisplayInfo.iDisplayInfoValue & ADL_DISPLAY_DISPLAYINFO_DISPLAYCONNECTED)
{
// check if display is mapped on adapter
if (pDisplayInfo.iDisplayInfoValue & ADL_DISPLAY_DISPLAYINFO_DISPLAYMAPPED && pDisplayInfo.displayID.iDisplayLogicalAdapterIndex == nAdapterIdx)
{
// check for eyefinity configurations
int nNumDisplayMap = 0;
int nNumDisplayTarget = 0;
ADLDisplayMap* lpDisplayMap = NULL;
ADLDisplayTarget* lpDisplayTarget = NULL;
ADL_Display_DisplayMapConfig_Get(nAdapterIdx, &nNumDisplayMap, &lpDisplayMap, &nNumDisplayTarget, &lpDisplayTarget, ADL_DISPLAY_DISPLAYMAP_OPTION_GPUINFO);
if (nNumDisplayTarget > 1)
{
int nSLSMapIdx = 0;
int nNumSLSTarget = 0;
int nNumNativeMode = 0;
int nNumBezelMode = 0;
int nNumTransientMode = 0;
int nNumSLSOffset = 0;
ADLSLSMap SLSMap;
ADLSLSMode* lpNativeMode = NULL;
ADLSLSTarget* lpSLSTarget = NULL;
ADLBezelTransientMode* lpBezelMode = NULL;
ADLBezelTransientMode* lpTransientMode = NULL;
ADLSLSOffset* lpSLSOffset = NULL;
// Display Group
ADL_Display_SLSMapIndex_Get(nAdapterIdx, nNumDisplayTarget, lpDisplayTarget, &nSLSMapIdx);
ADL_Display_SLSMapConfig_Get( nAdapterIdx, nSLSMapIdx, &SLSMap,
&nNumSLSTarget, &lpSLSTarget,
&nNumNativeMode, &lpNativeMode,
&nNumBezelMode, &lpBezelMode,
&nNumTransientMode, &lpTransientMode,
&nNumSLSOffset, &lpSLSOffset,
ADL_DISPLAY_SLSGRID_CAP_OPTION_RELATIVETO_CURRENTANGLE );
for (unsigned int i = 0; i < nNumDisplayTarget; ++i)
{
fprintf(stdout," AdpIdx %d DspIdx %d SLS X: %d SLS Y: %d\n",lpSLSTarget.iAdapterIndex, lpSLSTarget.displayTarget.displayID.iDisplayLogicalIndex, lpSLSTarget.iSLSGridPositionX, lpSLSTarget.iSLSGridPositionY);
}
}
}
