Re-enable onboard video outputs after adding graphics card ?
Hello
I am researching building a new computer. Building a computer using the latest Intel Haswell CPU motherboard. Mainly looking at the Z87 chipset based motherboards for clocking flexibility. I notice the norm is to now have an integrated onboard GPU built in with HDMI, DVI, and VGA outputs. Also, I've read that plugging in a graphics card typically shuts off the onboard GPU outputs - with an "auto" detect BIOS setting. I have an existing PCI graphics card. I am wondering if I will be able to transport it to the new computer. Specifically, will I be able to re-enable the onboard GPU outputs in BIOS to get a total of 4 display outputs? That is, 3 outputs from the onboard GPU and 1 output from the PCI graphics card? Thanks for you help, Forrest |

I don't believe it, but I just found an answer here. http://www.intel.com/support/graphics/sb/CS-031040.htm "Can I install an external PCI Express* graphics card and use it in parallel with Intel graphics? No, Intel graphics cannot be used along with an external PCI Express graphics controller. Installing a PCI Express graphics controller will disable Intel graphics." I can't see why that would be the case. And I thought people were enabling both, so they could do QuickSync with the Intel GPU. http://en.wikipedia.org/wiki/Quicksync Paul |

I wonder if not only the motherboard must support such a capability, but the video driver and windows support such a permutation as well. |

Makes we wonder if Intel wrote the driver for onboard video and can thus state definitevily that adding a graphics card doesn't work - today. Not familiar with QuickSync. Encoding / re-encoding, interesting. Had no idea that capability was on the chip. |

I wonder if not only the motherboard must support such a capability, but the video driver and windows support such a permutation as well. It sure is nice to get conflicting information. I downloaded a Sabertooth Z87 manual... http://dlcdnet.asus.com/pub/ASUS/mb/...rtooth_Z87.pdf and on page 3-32 (PDF page 98) it says: iGPU Multi-Monitor Allows you to enable both integrated and discrete graphics for multi-monitor output. The iGPU shared system memory size will be fixed at 64MB. If that motherboard can do it, then check the manual on the other Z87 motherboards. And this is why you check those manuals, to get the "real scoop". Maybe Intel just disables it on their own motherboards ? Paul |
