1080Ti with three 1440p monitors (one 144hz)? Will this work?

[SpatzST]

Long story short: I have two 1440p monitors 60hz, and one 1080p 144hz. Connecting all three is great, works no problem.

I replaced the 1080p with another 1440p 144hz monitor. My system is crashing and burning. My card refuses to output to 3 monitors at once. Plugging in three monitors causes all screens to go black and won't show any picture until a hard reset.

My question is, will a 1080Ti support three 1440p monitors? I am understanding that it should. I only game on one monitor, will just having the extra monitors connected kill my fps? Perhaps I should run one through my motherboard?

Any idea why I can't connect all three without blackness?

SOLUTION: Turns out using one non VESA compliant cable was ruining everything. I swapped out the one cable I had with the one that came with the monitor, stamped DP, and they all work without a hitch now!

1080 Ti specs say the max digital resolution is 7680x4320 (which is 3x1440p) @60Hz. So no, doesn't sound like this will work.

So I would need to put one monitor through my motherboard to keep it off the card?

What mobo and what CPU? From what I've heard some motherboards allow both integrated and discrete graphics to be enabled at once, some don't.

Hmm. I don't remember offhand I need to look.. I wanna say its like a ... MSI Z170 M5? or something, that sounds familiar. i7 6700k i think I have.

Yeah, I guess you'll just have to connect one monitor to your mobo and possibly fiddle around in the BIOS to see if you can get both GPUs outputting at once. Probably need to install Intel HD graphics drivers as well.

I was on the phone with EVGA support who tried their best to help but really had no other idea besides run a driver uninstall utility and try it again. ONE TIME I got it to work... with HDMI. That is, 2 displayports and 1 HDMI. But then I went to change my refresh rate down to 60hz from 144 and it all went black. I managed to get one monitor running through my motherboard instead.. so two displayports into the GPU and 1 HDMI into my motherboard.. I'm not sure if this is beneficial.. I suppose it is since my gfx card has less to render when i'm gaming?

I'm just somewhat upset that my gfx card is not working as it should... I am considering replacing all my DP cables to maybe some better ones, perhaps mine are causing an issue.. not sure.

At this point i'm just annoyed that I "can't but should be able to".

So should my i7-6700K be able to support a 2k monitor ok? not for gaming, just maybe netflix at most.

Yeah, your iGPU should be able to output 1440p/60Hz over HDMI.

However, come to think about it, doing 1x1440p/60Hz and 1x1440p/144Hz is still greater than the 1080Ti's maximum resolution of 7680x4320/60Hz, in terms of pixels per second. Not sure if that is significant.
