Lucid Virtu should work in two modes, i-Mode and d-Mode, in which the display should be connected either to the port integrated in the motherboard (i-mode) or in the discrete card (d-mode). The configuration should not be done as using one display in each of the video controllers, only one should be used
I am an CG artist and have used 2 Displays on 2 separate cards for years now.
After getting the i5 i decided the HD4000 was strong enough to fuel my secondary screen - and so far it's doing a great job, besides not waking up from sleep.
Thanks for your answer, but not using the HD4000, or only connecting one screen is not really a solution.
I already contacted Intel directly, maybe they can help. Can only be a problem with their driver, ASRock's drivers or a simple impossibility due to Lucid.
I'll see and report back.
