HD4000+OpenCL: do I need to connect monitor, do I need GPU-enabled chipset?

My i7-3770K is just ordrered, I have no it on hand now and unable to try myself yet.

The questions are

1) Do I need to connect monitor to internal graphics port to use OpenCL on GPU part of Sandy Bridge? Or drivers will load either I've no monitor connected to it. OS is Windows7 x64

2) I have motherboard with P67 chipset. So, I've no internal GPU-related settings in BIOS (enable/disable, GPU frequencies).
Will OpenCL work on HD4000 on this M/B? Do I need to change it to something with GPU features enabled (Z77 chipset or so) ?

Hi,

Yes, you will need to connect your display to the internal graphics display port on Ivy-Bridge. Windows 7 x64 is supported.

No, OpenCL on GPU won't work ifyou have a Sandybridge.

Is it hardware or software limitation? Video output shouldn't be needed to perform OpenCL computation on GPU part, isn't it? Would it be possible (with proper OpenCL driver, for example) to use HD3000 built-in into i5-2500K to perform OpenCL computations on P67-based motherboard? Or it's beyond software thing?
