Trying to do multiple monitor setup with sli, confused.

Hi, 

How do multiple monitors work with sli? 

 

Here is the setup 

28" 4K Monitor 60Hz Freesync (Freesync not used obviously) 

32" 4K Monitor 60Hz G-sync 

27" 2K* Monitor 144Hz G-sync 

*Assuming 2K is 2560x1440

 

Asus Rog Strix 1080ti OC

Sli with MSI 1080ti Seahawk X. 

 

The Seahawk has 3 display port ports and it will be on top (main) so can I just plug them all into that? Or will I have to split it between the two?  I'm confused what the resolution would be for all 3 could I trick the computer into thinking the 2K Monitor is 4K when I am using all 3 so it would be 11520x2160 or would it have to be 10330x1440?  

 

The max resolution for the Asus is 7680x4320, the msi doesn't list it, so would the 2 cards combine or am I still limited to 7680x4320?  I'm confused. 

 

Last thing, if gsync was on would that limit the 144hz to the lower 60Hz monitor? Or do they work independently? 

 

Thanks!

Max res is per monitor. You're fine there.

I would do the 144hz monitor on the primary GPU, and the two 60Hz monitors on the secondary GPU, but I don't think it actually matters. Plus SLI scaling isn't all that useful in many games, so personally, I wouldn't even use it. 

Fine you want the PSU tier list? Have the PSU tier list: https://linustechtips.com/main/topic/1116640-psu-tier-list-40-rev-103/

The 2k monitor should be able to be set to 4k in Nvidia control panel with a custom resolution. Otherwise yes, plug all the display cables into the one graphics card.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Sli is just temporary until 2080ti prices come down. But sli works in gta v and far cry 5, which are the ones I care about.

just plug them all into the main card. Doesn't need to be the "top". Also use the igpu if you got one capable.

Why would I use an integrated Gpu?  Pretty sure the 9900K doesn't have one anyways though.

No reason not to. But if it doesn’t have one then it doesn’t matter.

I think it does actually, but how would I benefit from using integrated Gpu and sli Gpu's?  Could they all work together?

Well they would work together by not using the cards to drive the monitor. 

 

That much resolution wouldnt allow the card to down clock anyway. 

 

I always use the igpu when sli and multiple monitors. Even more so with surround.

So what your saying is plug the displays into the motherboard so they go through the igpu then the monitor, so for simple stuff like YouTube the Gpu's aren't used at all?  Good idea, but mobo only has 1xhdmi port.

Well that's one less monitor on the cards. Most of my boards have dp and hdmi or dvi and hdmi. Also nice for trouble shooting when and iff you have problems with the gpus. Always some form of display.

Well if you need hz just to watch youtube, sounds like you just need to plug them all into the "main" card like sli says too.
