Bad NvAPI_GPU_GetScanoutConfiguration output with a MOSAIC and Quadro driver 375.63 and newer

The NvAPI_GPU_GetScanoutConfiguration function of the NVAPI returns wrong desktopRect coordinates of the displays of a MOSAIC with Quadro driver 375.63 and newer. With older version of the driver (369) desktopRect coordinates are correct.

Our setup is:

  • 1 Quadro K620 with one display connected.
  • 2 Quadro M4000 connected with a SLI bridge.
  • 8 displays are connected to the M4000 and are in a 2x4 MOSAIC.
  • NVAPI R378
  • Quadro driver 377.35
  • Windows 8.1 (64 bit) and 10 (64 bit)
