Hello,

I purchased two MSI GTX 1080ti Gaming tonight and I just realized that the cards only have 2 display port connections.  My current set up is using three Asus PG279Q 1440p 165hz monitors so I need to be able to connect them all via DP.  Can I still use Nvidia Surround just by plugging two DP cord into the top card and one cord into the bottom one?  This is a possible deal breaker for me if I am unable to get this working.  :(  I was looking forward to upgrading from my current MSI 980ti SLI set up but I do not understand at all why they would remove a DP connector.

GTX 1080ti Gaming indeed only has two DP ports (and two hdmi/ oneDVI). Youz will need an adapter for hdmi->DP.

Hello.  I found this adapter: https://www.newegg.com/Product/Product.aspx?Item=1B4-0133-00017&ignorebbr=1

Would that work and I be able to get 165hz 1440p on all three monitor with nvidia surround?

Hi

It is quite hard to say. This is the specification mentioned:

Compliant to HDMI 2.0 and DisplayPort 1.2a versions

Resolutions up to 4096x2160@60Hz, 8-bit color

HDMI 2.0 throughput up to 18Gbps, DisplayPort 1.2a up to 5.4Gbps/lane

Up to 12-bit color at 1920x1080

3D video support up to 1080p @120Hz


I would suggest you ask NewEgg to test it with some monitor that is at least 144Hz 1440p.

HDMI is limited to 120Hz.
But 120Hz is more than enough (for any monitor or TV).
That 165Hz is advertising and nothing more.

So then I should be able to just run two monitor via DP and the third with HDMI without worrying about getting an adapter?  I'm using this set up mostly for racing games.

Seeing as how you have 2 1080's , it may be worth a try putting two screens on one card and one on the other. To be honest, SLI is troublesome at best so if you can avoid that route...
The problem is however not with SLI itself but with support from developers. Everyone points fingers at everyone else, so the consumer will likely never know who is really at fault.
If you are willing to try, you can always use a dp to hdmi connector/converter. I have personally had problems trying to change my cabling to all dp. hdmi to dp seems to be troublesome.
But that is just my experience. So I prefer going from higher standard to lower(DP-HDMI) rather than trying to upscale (HDMI-DP).
The biggest difference on the Asus PG279Q is going to be refresh rates Display port:2560x1440(up to 165Hz) VS HDMI:2560x1440(60Hz)

I tried putting two screen on one of my 980ti and one on my secondary 980ti but nvidia control panel won't let me enable surround on all three monitor.  They have to all be plugged into the same card I guess. 

I canceled my order for the cards until I am able to for sure know that I can use these the way I want.  Some other brands have three DP ports but I would rather stick with MSI if possible.

Found this on Nvidia surround page, they built a tool to help people configure their displays and work out what connectors you may require.Give it a try and see if it helps.
It even states that 2 GTX 1080 cards can run up to 5 monitors plus an accessory display.
I found the tool helpful with diagnosing my own monitor setup,Luckily you have identical monitors so your nvidia surround should work as intended.

Just noticed it doesn't show the key legend as to what the symbols mean.
Sorry about that.

Yea, I should have posted a follow up but I was directed to that config tool the other day and figured out I could make it work.  Still this is a problem for others who want to run the same type of setup but only have one card.  My two 1080ti should be here Wednesday.  :)  I can't wait to get them into my rig.
