Not a conclusive test, but observed these:NedSlider wrote:Question: Out of curiosity, do both controllers work (separately) if a monitor is hooked up?
* A Dell with i7-6700 and Nvidia Quadro M4000 and Windows 7
Code: Select all
Primary display
( ) Auto ( ) Intel ( ) Nvidia
* Set Nvidia as primary. Only Nvidia gives output but both controllers are shown in device listing.
* Set Intel as primary. Output only on IGP. Nvidia's tool does not start in Windows.
* Restore Auto: Output still on IGP.
* Disconnect display from IGP and reboot. Display on Nvidia.
lspci on this host now: only the Quadro is listed. The Intel IGP is clearly disabled. Now I cannot tell, whether IGP was on the list before meddling with the BIOS.
