Intel HD 630 + GTX 1080

So we're upgrading to 5 monitors & the NVIDIA software says that the GPU can only handle 4 monitors, so i have enabled the onboard HD 630, with confusing results.

When I installed the 630 driver the monitor comes online & I can use the monitor as normal but one of the monitors attached to the 1080 goes offline.

When i use windows to detect the displays, one of the monitors (attached to the 1080) is shrunk down(showing that it can't be used/ isn't attached)

Surely 4 on the GPU & 1 onboard is 5 & should work without issues. All drivers are up to date.

Any ideas would be appreciated?

Cheers C
 
If duplicating rather than extending the display your connected monitors will need to be the same resolution or lower than the primary monitor. Windows doesn’t like mixed resolutions.
 
I don't think you'll be able to make use of the onboard 630 GPU and 1080 at the same time as they're two separate adapters.

Windows will see both but won't be able to combine them as one or use them simultaneously.

You'll need either DP cables in daisy chain (if your monitors support it) or a second 1080 in SLI.

Not true - I've had displays connected to a mixture of AMD, NVIDIA and Intel all in the same machine before now.

Using SLI will get you no extra functioning display outputs (as the outputs on the 2nd card are normally disabled).



As to why the OP is unable to connect 4 displays to the card - not sure.

How are you connecting the 4 displays to the 1080? e.g. what connectors? (as that can make a difference, especially if any adapters are involved)

Oh in that case I stand corrected.

I'm sure quite a few here used to use a second card in SLI for multi monitor setups (not just for performance) but I may be wrong. Maybe two separate cards without the SLI bridge.
 
4 displays are working on the 1080, but getting a fifth connected onboard results in one of the 4 connected to the 1080 shutting off. Removing the 5th lets the 4th one become useable again. I’ve done this several times on different setups in the past without a problem.

I’ve ordered a 1660. I’m hoping to stick 3 on the 1080 & 2 on the other to solve the problem.

Although I’m still at a loss as to why 4+1 doesn’t = 5
