Odd AMD Graphics Card Issue. It Erases Integrated Intel from Device Manager?

Geekomatic on 18/05/2019 - 21:14

So, I'm asked to have a look at a tower with this motherboard: https://www.asus.com/Motherboards/P8H77M/specifications/moth…. The system "used to", up until a few weeks ago during a move, display dual monitors. Win 10/64.

I cannot get any sort of dual going today. In fact, If the graphic card is installed (GT-610), then device manager simply doesn't "see"/display the onboard Intel graphics. It simply ceases to exist. I've enabled multi-monitors in the BIOS and then tried setting onboard 1st. No go. Remove dedicated card, Intel onboard comes back.

I was told that the two monitors had been hooked up forever and worked fine. The GT-610 has one DVI & one HDMI. The monitors have HDMI & VGA. Any connection made with integrated only is blank. "Sleep mode", detected. The onboard had VGA/HDMI/and DVI. One of the monitors was plugged to HDMI on the dedicated & the other (for whatever reason) was connected to the onboard via HDMI-to-DVI adapter.

I've tried everything I can think of. I reset CMOS & BIOS to factory. The Asus drivers for the onboard wouldn't install (hardware didn't support", even though it came off of the Asus site). I eventually uninstalled the integrated & restarted to get the newest from WU.

Still, I cannot get dual monitor, cannot get the integrated to show when the dedicated card is in the slot. I've looked at hidden, tried activating in safe mode, etc.

Anyone here run up against this?

Cheers

    It's common for BIOSes with integrated graphics to disable the integrated one whilst a discrete card is installed - I'd be rather suprised if the onboard HDMI and DVI were working. It SOUNDS like someone has plugged them into the onboard port for one of the monitors recently without realising - or without admitting.

    Easiest solution is to hook both monitors to the graphics card, via DVI and HDMI, and tape over the motherboard's ports to avoid confusion. It'll work as expected, nobody has to admit they had a fiddle, and you get the brownie points for figuring it out :)

      This. Why would an adaptor be used if it was redundant?

    Agree with Switchblade88, can't run dedicated and on-board graphics at the same time. Pick one.

      Nah

      It actually depends on motherboard, some have an option in the bios to allow both GPU and onboard at same time, plenty of dells and hp’s allow that. But you need to enable a setting in bios, someone might have changed that setting. The setting to allow both at once is more than likely not a default setting, hence why resetting the bios is not fixing the problem. So you might need to find correct setting and set it.

      Have used it many times to allow for running three monitors.

    I can see from the manual the IGP multi-monitor BIOS option is meant to function as you expected. Is there a reason they want the second monitor running off the integrated? It seems like it'd be less work just to plug it into the graphics card.

      Because plenty of cheaper GPUs only have 1 digital and 1 VGA output. Using the integrated digital output gives you 2.

      Not in this case though.

    Occam's razor, it has always been plugged into the dedicated card, until they moved.

    GT610 is Nvidia ?

    The old Asus P4R800-VM motherboard allowed that as an early triple head feature. Maybe check that manual to see how they handled it. I 'think' the graphics card had to be ATI to match the onboard chipset and driver. I think also that Linus Torvalds of Linux fame thinks Nvidia are the devil of non cooperation with specs and protocol information so coexisting might be unlikely with Intel graphics. I don't think the various graphics manufacturers have any resource standards or cooperation between each other, probably the opposite. It feels really messy to think an Nvidia card capable of two displays would happily coexist with a third from a different manufacturer.

    Given the onboard graphics usually use shared system RAM, that might be a way to see the old configuration if it ever worked. Maybe an old system or event log will have system memory shown. If the onboard graphics are enabled it will usually be a less graceful number like 2GB - 128MB or whatever. Maybe check memory with onboard graphics on and off and scan the HD if it's a distinctive number trying to find a log.
