Could you please provide the driver versions of the releases that you have tested with? And can you confirm if this happens of its resolved or alleviated with the drivers provided by Asus*?
In addition, please provide the full model of the monitor displays that you have used, what type of ports/cables are you testing? Do you see this issue you use the system in Windows* safe mode? Or with no Intel(R) video drivers installed or disabled (through Device Manager)?
Please attach the dxdiag report from that system. To get the report, go to start menu > type dxdiag> click on save all this information, then open the file and copy paste here the contents on it.
Chip was defective, returned to vendor. Put new chip in and problem was solved.
Alright, it seems that it was a hardware issue then. Glad to know you resolved your issue.
