I got one ASUS GeForce GTX 1080 8GB ROG STRIX Graphics Card, and it has two display prots, two HDMI, and one DVI-D port. I am planning to buy three ASUS PG258Q 240hz monitors, I am guessing that DVI-D port doesn't support 240hz? Any solution for triple 240hz monitors setup?

I personally think that 24.5", 1080p isn't really ideal for gaming.

You're not getting much HEIGHT, and many games don't run great on triple monitors.

*Personally, I think the best compromise is to get a 3440x1440 screen. That's limited to 100Hz AFAIK, but if you use GSYNC (NVidia) or Freesync (AMD) you get a smoother gaming experience.

240Hz is going to be problematic for a few reasons including how to avoid SCREEN TEARING in games. Some will be okay with VSYNC OFF, but many won't be.

*Since you have an NVidia GTX1080 I would consider the Asus or Acer 34"/35" (see pcpartpicker), GSYNC, ultrawide.

Again, 21:9 is wider than 16:9 but not as wide as a TRIPLE MONITOR setup. If you want a wider gaming experience than 16x9 I think 21x9...
The highest DVI-D supports is 120Hz @ 1080P. So you will need a video card with display ports to drive 240Hz. I think all the 1080 Ti's have 3 DPs, so either get one of those or buy another 1080 and SLI it. You won't get close to 240FPS in any game with 1 card anyways.

Spending $1800 on monitors is insane when you won't be getting anywhere close to 240FPS. High refresh rate is overrated. I can barely tell the difference between 60hz and 165hz.
 
DVI-DL maxes out at 144hz for 1080P, and that monitor is HDMI 1.4 only, which doesn't have the bandwidth for 240hz anyway.

Many GTX 1080s have 3 DP ports, which is actually what you want, but I guess it's too late to return the card?

Are you really planning to game in 2D surround across 3 240hz displays? What games are you targeting here? Because 240hz is a big, big ask for any CPU regardless of the graphics settings, and with 3 240hz displays you're effectively asking a GPU to push 12 times the pixels per second of a standard 1080P @ 60hz set up.

If you're only gaming on one display, then don't waste your money on 240hz displays for the desktop.

If you are gaming across 3, then you're probably better sticking with 144hz displays. Alternatively, can I encourage you to consider going ultra-wide instead? For the kind of money you're looking at you could get a very nice ultra wide with Gsync, which should be nice and smooth, work with your current card, and have a fraction of the issues you're going to have to wrestle entering the work of multi-screen gaming.

Again, 21:9 is wider than 16:9 but not as wide as a TRIPLE MONITOR setup. If you want a wider gaming experience than 16x9 I think 21x9 is where it's at and triple monitor is too wide, distorted, and there's a bezel gap between screens.

**Also, if you cap a fast paced game at about 90FPS (to stay in GSYNC mode, not switch to VSYNC ON/OFF like normal) it's still really responsive. Gaming above 100FPS (i.e. 144Hz GSYNC panel) in my experience with GSYNC/Freesync has rapidly diminishing benefits to response time and game smoothness.

In case it's not clear, the RESPONSIVENESS that people want with 240Hz, non-GSYNC (normal) panels is achievable at lower Hz/FPS on GSYNC. It's hard to explain this to people without trying it for yourself though.

Thanks for the replies! I am not planning to use all three monitors for gaming, so yeah I think three 240hz monitors is a bit of a waste. What do you guys think about one PG258Q for my main gaming monitor, and two PG248Q for my other two monitors?
 
I'm totally with @Photonboy. Assuming you're purchasing these for 3 screen gaming (why else would you buy 3 240hz displays!?) a 1440P ultrawide should give you a much better experience at a fraction of the hassle.

There's a reason that both Oculus and HTC settled on 90z for their VR headsets after investing many, many hours over several years of testing. That's not to say that 90hz is perfect, or that no particular individuals could ever tell 90hz from 144, or 240. But even 90 -> 144hz puts you into the territory of diminishing returns and 144hz -240hz is beyond it IMHO.

Have you seen these monitors in action? Can you get yourself to a store or somewhere you can actually test out these things to find that balance that suits you? This really isn't an area where you want to purchase based on a spec-sheet, unless you know what suits you.
 

Why would you get any more than a 60 hz display if you're not gaming on it? That's still a relatively expensive 180hz display. The only benefit I can possibly think of is a smoother mouse pointer when you move it really quickly. Is that worth hundreds of dollars?

Something like this will work fine for you second and third displays: https://www.newegg.com/Product/Product.aspx?Item=N82E16824236153&cm_re=asus_1080P-_-24-236-153-_-Product
This one would allow you to swivel one or both into portrait displays, which is actually really handy for lots of web content, etc: https://www.newegg.com/Product/Product.aspx?Item=N82E16824236798&cm_re=asus_1080P-_-24-236-798-_-Product
 
Just for a point of comparison, you could get two of those relatively cheap 1080P displays, and then with the money that frees from your budget you could get a truly high end gaming display like this one: https://www.newegg.com/Product/Product.aspx?Item=N82E16824236717

Review here on TH for that display is here: http://www.tomshardware.co.uk/asus-rog-pg348q-34-inch-curved-g-sync-monitor,review-33670-6.html

As I said above, monitors are a personal thing and that premium ultra-wide might not be your personal preference, but it's worth considering at least.
