Descriptive monitor name from D3D display adapter ID


As the question suggests, I'm trying to pull a descriptive monitor name to match with a display adapter name. The code below gives me a device ID like \.\DISPLAY1 which is understandable but not what I'm looking for.

    // Get name.
    D3DADAPTER_IDENTIFIER9 d3dID;
    d3d9.Get().GetAdapterIdentifier(iAdapter, 0, &d3dID);   
    dispAd.name = d3dID.Description;

    // Add monitor ID to display adapter name.
    FIX_ME // Not happy with this yet!
    HMONITOR hMonitor = d3d9.Get().GetAdapterMonitor(iAdapter);
    MONITORINFOEXA monInfoEx;
    monInfoEx.cbSize = sizeof(MONITORINFOEXA);
    if (GetMonitorInfoA(hMonitor, &monInfoEx))
    {
        dispAd.name = dispAd.name + " on: " + monInfoEx.szDevice;
    }
    else TPB_ASSERT(0); // Mute?

I've looked around the documentation for where to pull that actual name from but until now I haven't been able to find it. Sometimes I am a little stupid (or blind if you will), so I'll give it another go during my lunch break -- but perhaps someone can point me in the right direction? Thanks a lot.

(and by actual name I mean the one presented in the graphics configuration panel)


Solution

  •     UINT iOutput = 0;
    IDXGIOutput *pOutput = nullptr;
    while (DXGI_ERROR_NOT_FOUND != pAdapter->EnumOutputs(iOutput++, &pOutput))
    {
        DXGI_OUTPUT_DESC desc;
        VERIFY(S_OK == pOutput->GetDesc(&desc));
    
        MONITORINFOEXW monInfoEx;
        monInfoEx.cbSize = sizeof(MONITORINFOEXW);
        GetMonitorInfoW(desc.Monitor, &monInfoEx);
    
        DISPLAY_DEVICEW dispDev;
        dispDev.cb = sizeof(DISPLAY_DEVICEW);
        EnumDisplayDevicesW(monInfoEx.szDevice, 0, &dispDev, 0);
    
        // FIXME: far from perfect, but should do the job if a vendor driver is installed.
        //        Otherwise it just displays something along the lines of "Plug & Play monitor".
        SendDlgItemMessageW(hDialog, IDC_COMBO_OUTPUT, CB_ADDSTRING, 0, (LPARAM) dispDev.DeviceString);
    
        pOutput->Release();
    }
