I use my Intel IGP as primary display, connected to the monitor.
A Radeon 7950 is used as secondary card to perform OpenCL computations ... but I cannot use the 7950 in OpenCL because it has no attached monitor ...
I tried to disable ULPS, but didn't work.
I **CANNOT** undertand why I need a monitor attached to a GPU to be used with OpenCL. It's a non sense...
I must buy a VGA-dummy which is pretty stupid ... why not to put an option in the Catalyst Control Center to "use this card for physics" as NVIDIA's drivers do?
