Comment # 19 on bug 1193397 from Kourosh P.

To @Nikolai

In the BIOS Advanced > System Agent (SA) Configuration > Graphics Configuration
> Primary Display > 'Auto' was selected. The other options were 'CPU Graphics',
'PEG', 'PCIE' and I changed it to 'PEG'.
Advanced > System Agent (SA) Configuration > Graphics Configuration > iGPU
Multi-Monitor is already set to 'Disabled'. I rebooted the system with monitor
OFF and got the same result with DP NO Signal when monitor was turned on.
