has anyone experienced this issue of installing the OpenCL 16.1 driver, and then losing the dual monitor support that was native to the PC?
I am using a Dell setup-Precision M4800/i7-4810MQ/HD Graphics 4600/Windows 7, and experienced this in all the Dell machines that I tried.
Appreciate any advices to this issue.
In Windows, the graphics driver can be updated separately from the OpenCL and Media SDK installs. Have you tried updating to the latest 15.36 driver from downloadcenter.intel.com?
More info on driver and hardware support is available here:
Hi Jeff, appreciate your response.
However, it isn't working. It seems that the opencl 16.1 driver and the 15.36 Intel 4600 HD drivers are mutually exclusive.
If I run the opencl_runtime_16.1_x64_setup.msi file, it detects the existing 4600 driver and refuse to run unless it is removed.
So, I installed the opencl driver, and my software runs perfectly.
Then I run the 15.36 driver you recommended (win64_153631.4414.exe), and it replaces all the necessary drivers in the opencl installation, causing my software to fail at detecting device=ocl#0 (with in-software error message "Win/Intel 22.214.171.124 is not supported. Supported configurations are 126.96.36.199")
Now, I have no idea what is this Win/Intel 188.8.131.52 that has been detected. Is it related to the 15.36 driver?
And why does opencl refuse to run unless the driver HD 4600 is removed? Can I install an opencl setup without the need to remove any drivers?
In theory you should be more up to date and have more options if you remove the 16.1 components and update to the 2016 R2 release from from https://software.intel.com/en-us/intel-opencl/download. This will give you a CPU and GPU implementation, where the 16.1 release has CPU only. If you can wait a day or two I will try to get more info from the team.
