Multi-Display Configurations with KeplerMIXING GRAYSCALE AND COLOR DISPLAYSThe previous section demonstrated how to get the general characteristics of a displaysuch as extent etc, but more specific properties of monitors will decide how to layout ourapplication. For example, user interface and launching elements are normally placed onthe regular color LCDs while the radiological images will be rendered to the grayscaledisplays. A display is defined to be grayscale compatible if both the monitor and theGPU attached are grayscale enabled. To determine if a monitor is grayscale we parse itsEDID to get the model name and compare it with the list of enabled monitors. ThisEDID is provided by the NVIDIA NVAPI [5] – an SDK that gives low level direct accessto NVIDIA GPUs and drivers on all windows platforms. The following example showsenumerating the attached displays and its associated panel and GPU string. Refer to thecomplete source in CheckGrayscale.cpp for error checking functions and theisGrayscaleGPU and isGrayscaleMonitor string parsing functions.// Declare array of displays and associated grayscale flagNvDisplayHandle hDisplay[NVAPI_MAX_DISPLAYS] = {0};NvU32 displayCount = 0;// Enumerate all the display handlesfor(int i=0,nvapiStatus=NVAPI_OK; nvapiStatus == NVAPI_OK; i++) {nvapiStatus = NvAPI_EnumNvidiaDisplayHandle(i, &hDisplay[i]);if (nvapiStatus == NVAPI_OK) displayCount++;}printf("No of displays = %u\n",displayCount);//Loop through each display to check if its grayscale compatiblefor(unsigned int i=0; i
