Triple monitor set up need help!

[Alex_124]

So I have a 27" 4k monitor with a display port, 2 hdmi ports and a usb-c port. I also have a 27" 1440p 144hrz monitor with display port. Now I want to get another identical 144 hrz 1440p monitor for a triple setup. I believe there is no issues running different refresh rates. The problem is I made the mistake in buying the asus gtx 1080 strip which only has 2 display ports. So is there any way I can have the triple set up without resorting down to hdmi at 30hrz? Is it possible to use the display port if I got another gpu in sli?

Are you wanting to game across all 3 monitors at once, or simply have 3 displays?

If you are willing to get a second GTX1080 for sli, then buy one with 3 displayports and make that the master to which you connect all monitors.
EVGA, for example usually has 3 displayports.
It is ok to combine different brands so long as the gpu is the same.
If gaming at 4k on three monitors, you are going to need that kind of horsepower.
