So I'm trying to run OpenCL calculations and related ADL operations on a multi-gpu (no SLI/CrossFire) setup. I just bough a new R9 270x. My problem is that ADL only works if there is an active display on the card. Active meaning: plugged in, turned on, and switched to the card's HDMI input. When this is not the case (no display plugged in, display switched to a different input) all ADL API calls return errors and the overclock options are removed from the CCC. This really screws up my multi-gpu plans. Can something be done about this? Is this a bug, something I have to live with, or can it be fixed? I've tried using the latest stable and beta drivers.
I have you found a solution? I have the same problem.
