HD 4000 With Discrete GTX 680 Dual Monitor

[BreadFan]

Tried doing a search but not really sure how to search this. Is it possible to have a dual monitor setup where one monitor is connected HDMI to the HD 4000 and another monitor connected DVI to the GTX 680 and have the desktop span across both monitors (windows 7 or windows 8)? My gut tells me this isn't possible since it will be two separate signals controlling the monitors so I figure the best it could do is two separate desktops on the two monitors.

I'm pretty sure it can do it, try hooking it up and seeing if it works, as long as your motherboard supports having both IGP and GPU turned on. If not, why not just connecting them both to the 680?

I don't have both yet. Just brainstorming a new build. I know for sure I can connect both to the GTX 680 but was just curious if it were possible to have one connected HDMI to the HD 4000 and still be able to span the desktop across both monitors.

The bold is the important part. We have a few Dell machines here whose motherboards DO NOT support that. It does state that in the manual however.

it won't work like that.
if you have a z77 mobo then you can configure "virtu mvp" on it and then it can work.
your discreet card and hd4000 will work together to give better performance.
but as of now "virtu mvp" is stillin developing stage and improving with time. as of now there are lots of crashes but hope for better drivers is there in near future.

Why can't both be connected to the 680?

 

[Ventanni]

I ran my setup exactly like this and it worked just fine. I had my secondary monitor output from the HD4000, and my primary output from the Radeon 5850. Worked like a champ. It acted exactly the same way it would have running from a single GPU.

Except video was a lot more washed out on the HD4000 than it was on the 5850. It was extremely noticeable, but I'm sure I could have fixed that with a little bit of tinkering. I just didn't know how. Not a problem if I had both hooked up from the Radeon 5850 though.

 

[2is]

That's exactly how I have mine setup (except using DVI) No issues at all, it functions exactly as it would if they were both on the 680

 

[TakeNoPrisoners]

I did that for awhile with the integrated GPU in my mobo and my 5850.

Having both connected can cause more power use from the discrete card, so you have lower power consumption when not gaming when using discrete + IGP over 2xdiscrete.

Chipset Z77 and later support this....I have 3 16x10 panels for work, centre via IGP and outer unit via 610.....the Lucid MVP is only for gaming

Yep, that's why I did it. I saw at least a ~25watt reduction at the wall. It also frees up a few MB of vram too.

I would have never considered this. Thanks.

 

[BreadFan]

Thanks to all for the answers. Again, I know I can connect both to the 680, I was just curious if it were possible to run it in the configuration I was asking about. Once I get everything from the build, I'll give it a try and see how it goes. Thanks again.

hate to bump an old thread, but i thought i'd start here...and if it doesn't garner some responses, i'll ask my question in a new thread.

the simplified question is this: which Z77 mobos support simultaneous use of the intel HD 4000 iGPU and one or more discrete GPUs? i'm not trying to run multiple monitors using both the iGPU and a dGPU like the OP...rather i would like the HD 4000 iGPU to be a dedicated display GPU and my discrete GPUs dedicated crunchers. that way neither of my dGPUs have to allocate any resources to running the display and i can avoid GUI lag altogether. long story short, i recently purchased an i7 3770K and a Gigabyte Z77X-UD4H mobo, and it turns out that this board won't allow me to use the iGPU and any dGPUs simultaneously. from what i gather online, particularly in THIS THREAD in Tom's Hardware forum, only certain Z77 mobos support simultaneous use of the iGPU and dGPUs, and it is typically a "multi-monitor" setting found in the BIOS that enables it. my mobo's BIOS does have an option to enable the iGPU, as well as an option to select the display interface (IGFX/PCIe/PCI/etc)...but there is no option to enable multiple-monitor setups using the iGPU. you'll note in the thread i linked that someone has an "iGPU multi-monitor" setting in his/her ASUS P8Z77-V PRO mobo's BIOS that allowed him/her to do a multi-monitor setup using the iGPU and dGPUs (or more importantly, allowed him/her to use the iGPU and dGPU(s) simultaneously, regardless of whether they were to run multiple displays or not)...so obviously the ASUS P8Z77-V PRO is one such mobo that allows simultaneous use of intel iGPUs and dGPUs, but what are some others?

TIA,
Eric

Well I can confirm the Asus z77 pro CAN do it. In addition to my second monitor I also have an HDMI connection going to my receiver for the times I want to put something up in the TV.

I also have a Gigabyte Z77-D3H that I'll test out a 2nd display on the IGP (in addition the one on thats already on the IGP) and report back.

thanks, i appreciate it. i wonder if its safe to assume that ASUS boards higher in the lineup than the P8Z77-V PRO (like the Sabertooth, the Maximus V Formula, the Maximus V Extreme, etc.) can also use the iGPU and dGPUs simultaneously...

 

[2is]

Well I know my gigabyte can do it simultaneously, its setup that way now, but you're wanting to know if you can do dual displays, both being driven by the IGP correct?

 

[SolMiester]

The IGP on SB & IB can run multi monitors. If the dGPU doesnt have displays connected, it should just act like any other expansion card...Ill dig out some adapters and see what happens with my work unit...they are DVI only!

edit - how many displays? 2 or 3?

 

[2is]

Just confirmed the IGP on my gigabyte board has no problems with 2 displays. I currently have three hooked up. One on my dGPU and 2 on the IGP. This is with a 2500k

 

[Sunny129]

my apologies if it wasn't real clear on what i'm trying to accomplish - i'm only trying to run a single display off of the IGP. but i also want to install one or more discrete GPUs and dedicate them strictly to crunching (they won't be displaying anything). of course in order to be able to do this, i must first have a mobo that allows simultaneous use of both the IGP and discrete GPUs, regardless of the fact that i'll only be running a single display on the IGP only. 2is - the fact that your Gigabyte mobo can do it is promising, b/c it makes me think that perhaps i don't need a different Z77 board, and that i'm overlooking something (like a setting in the BIOS or something). unfortunately our Gigabyte boards use different BIOS's, so its possible your mobo/BIOS has a setting that mine doesn't. is there perhaps an "iGPU multi-monitor" setting enabled in your BIOS?

 

[jkauff]

The setting is pretty well hidden in the Asus BIOS, maybe it is in the Gigabyte as well.

man i feel like i've been through the BIOS a million times and just can't find any such option...but i'll check again when i get home this evening.

also, i suppose i should explain in detail what's actually happening when i try to do what i want to do. at first i fired the system up w/ a single GTX 580 installed. i went into the BIOS and enabled the IGP, as well as set the "initial display first" to IGFX. but after "saving and exiting" the BIOS, there was no video output to any of the video ports on the back of the mobo...and once in Windows, only the GTX 580 was detected. i did more research and found that the system must be void of any discrete GPUs and the display connected to the IGP (connected directly to the mobo) in order for Windows to detect it and allow drivers to be installed for it. so i did that, and everything worked just fine. but upon adding back the GTX 580, making sure the IGP was enabled in the BIOS, and making sure that "initial display first" was set to IGFX in the BIOS, i still got not video output through the mobo...and upon re-entering the BIOS, i noticed that the IGP setting was back on "auto" instead of "enabled," as was the "initial display first" setting. i would think that if there were an iGPU multi-monitor setting in the BIOS, it would be right next to these two options...but no such luck.

 

[Sunny129]

well i just had yet another look through every single BIOS option, and still i cannot locate any sort of "iGPU multi-monitor" setting.

2is, are you able to use both the iGPU and dGPUs by simply enabling the iGPU in the BIOS, or can you confirm the existence of an enabled "iGPU multi-monitor" setting in your BIOS? and if so, would you be able to snap a picture of it and post it? i'm fairly confident that i've looked through my entire BIOS, but i suppose its possible that i missed something, or perhaps was just looking in the wrong place...i know its a long shot b/c as our Gigabyte boards use different BIOSes, but i figure its worth a shot.

TIA,
Eric
