Reddit reviews Accell mDP to DVI Adapter - Mini DisplayPort to DVI-D Single-Link Active Adapter - AMD Eyefinity Certified, 1920x1200 (WUXGA)

ATI Radeon 5870 Eyefinity Edition. link
got one of these and it's currently powering 5 monitors.

If you don't have display port, you need "active adapters" for everything above 2 non-display port. You also can't use analog VGA monitors. (they have to be digital)

Here's an adaptor for $30. link It only works for resolutions up to 1920x1080.

Edit: I haven't really researched the 6950 and 6990 series but those are the newest generation and they might not even need active adapters. I'll look into it ^_^

Here's a page with AMD's new offerings to the table. a few 6950's might be your best bet link

Upon further research, something like this would work well.

I always reccommend the QNIX QX-2710. since it's the most budget friendly and is just as good as other Korean 1440p monitors with the added bonus of being overclockable

• $275-$300
  
  
• 1440p
  
• PLS Panel (Samsungs equivalent of IPS)
  
• 27"
  *Overclockable up to 120hz
  
  (usually reaches around the 90's on average)
  
  
  
  
  
  
  What video outputs does your GTX 590 Have?
  
  For the desktop you'll likely be able to keep all 3 monitors hooked up, you just need to make sure that the 1440p monitor is connected using Dual Link DVI which your card may have and if not you can do through some variant of display port adapter like a DP or Mini-DP to DL-DVI adapter and you can use the remaining video output for the 2x 1080p monitors
  
  For the Macbook pro you can do the same thing, just use one mini display port adapter to DL-DVI, and another adapter to one of the video inputs that the peripheral 1080p monitor accepts and you can use the HDMI for the 3rd monitor using the second 1080p one you own.

Here's the one I've been using for the past couple years.

I bought this one from Amazon and it worked great with my 6970:

Its single link though so if you want to go higher than 1080/1200p you'll need the more expensive usb powered type.

I needed an Active DisplayPort adapter to get a third monitor going on my 6950. It's possible you need the same.

You need an active MiniDP- DVI adapter. The passive will not work in conjunction with 2 other monitors in use. For 3 monitors to work, you need to use the 3 timing clocks on the card, 2 are reserved for DVI/HDMI and the 3rd is for the displayport. To use the displyport clock, you need the ACTIVE adapter to work properly.

Buy this adapter: http://www.amazon.com/Accell-B087B-006B-DisplayPort-Single-Link-Certified/dp/B004071ZXA/ref=sr_1_1?ie=UTF8&qid=1368418601&sr=8-1&keywords=accell+mini+displayport+to+dvi+active

Use an active mini displayport adapter like this one, and it should work.

Unless your monitors use a DisplayPort connector, you'll need to do things a bit differently.

Firstly, you don't need a 7870. A 7850 will be fine for three monitors. I'd say less than a 7850 might not be ideal. This card's cheaper and has a better, quieter cooler:

You'll also need both of these:

Or just two of these:

Now, let me explain myself. I'm assuming your monitors don't have DisplayPort connectors or HDMI connectors.

That AmazonBasics cable converts HDMI to DVI (which I'm assuming your monitors all have) passively, since HDMI and DVI share the same internals.

That Accell "active adapter" is required by AMD/ATI (same company) graphics cards to use a third monitor, if it doesn't have a DisplayPort input. It converts the mini DisplayPort connector from the graphics card to a more standard DVI connector.

If you do decide for whatever reason that you want six monitors, this graphics card in combination with the Accell adapters will work for you in a single card:

It's a bit pricey, but the fact that it can run six monitors from a single card is very impressive. You'd of course need six Accell adapters.

albert1854 was probably correct in his thinking, but I know I prefer a lengthy response, so I hope this helps you.

Ye ye, get this for your 3rd monitor and plug it direct into the laptop. Only way i've found Zbooks to display on 3 through the dock.

For my eyefinity setup on my gigabyte 7950, I use this passive adapter and this for my active adapter. I've had both for about 2 months and I haven't had any issues with either of them so far. However I don't believe either of them support 1440p.

You're going to need an active adapter for the mini displayport. I'm in the same boat -- quad monitors on a 7970. DVI, HDMI, and two of these babies.

Edit: Old, but still very relevant article on why you need an active adapter. http://www.overclock.net/t/721931/active-vs-passive-displayport-adapters-the-truth Even if you're not using Eyefinity, you still need it if you want to run them all off your 7850.

I just went through this and my third monitor does take awhile to show up (it is the one plugged in to the active adapter). Wish I had more info for you. Maybe try getting a different adapter? This is mine: http://www.amazon.com/gp/product/B004071ZXA/ref=oh_o05_s00_i00_details

Just as Streichholzschachtel said you would need active DisplayPort adapter.

Just a few hours ago, I replied the following on a similar thread, which could help you pick adapter if you decides to get one:

A while back, on a multi-monitor setup, I've used this HIS Mini-DisplayPort to DVI Adapter AMD Eyefinity-ready and it worked flawlessly right out of the box(at first i tried this Accell B087B-006B UltraAV Mini DisplayPort to DVI-D Single-Link Active Adapter ATI Certified, which did not work, even though it was ATI certified).

what you need is an active mini displayport to xxx adaptor. yes, it has to be active as a passive adapter will use up an HDMI/DVI channel and it wont work

Example: http://www.amazon.com/Accell-B087B-006B-DisplayPort-Single-Link-Certified/dp/B004071ZXA/ref=sr_1_6?s=electronics&ie=UTF8&qid=1373640297&sr=1-6&keywords=active+displayport

You would still need to do this even if you get a second card and xfire. when xfireing all monitors need to be plugged into the same GPU if you are using eyefinity if i remember correctly

Why are you adding a LAN card? The motherboard has dual gigabit NICs (on-board LAN).

Amazon, Newegg. I.e.

> So this should work no problem?

Personally I've never run that many monitors, but the board itself supports quad-SLI/CrossFire and the cards support 6 monitors each, you won't be running the cards in CrossFire though. Theoretically it should work.

The cards themselves come with two Mini-DP to DVI Passive Adapters that may work for a couple monitors per card, which means you might only need 16 mini-DP to DVI adapters.

I only have experience with 3 monitors, and my setup uses a DVI-I connection, a passive VGA to minidisplayport, and an active VGA to minidisplayport. 2 connections can be non displayport( or passive adaptors through displayport), everything else has to be either displayport or minidisplayport (or an active adapter to one of these). this page is of the AMD certified adapters. I bought these passive adapters for my one of my vga monitors, and one of these to connect connect my 3rd monitor.

I would suggest plugging in the hdmi from your tv, then buying one of the 5$ passive vga to DP or mDP adaptors, and 2 active vga to DP or mDP adaptors.

So this is the miniDP to DVI-D I adapter I use. I don't have a 144hz monitor (used it for AMD eyefinity) but I know this adapter is active as well as a dual link dvi and I've had it for about ~4years (it still works). I can't guarantee that it supports 144hz but I can't find any adapters that are specifically labeled as what hz they support. So I think its more the fact that the adapter you have is a DVI adapter and not a DVI dual link adapter.

You don't want to get into splitting a single DVI port into two separate monitors. It's possible but expensive and unnecessary. The 6850 and similar come with 5 ports like this. You can plug 4 monitors in directly and the drivers & Windows work very well with it all.

The only limitation is you can only use 4 of the 5 ports on the card - of the 2 DVI and HDMI you can only use 2 total. This means you need to use the DisplayPorts (specifically mini-DisplayPorts). For that to work you need the ~$30 active adapter for each, or 2 monitors that accept DisplayPort inputs. They're becoming more and more common, but the average cheap monitor just does DVI/HDMI.

ok, good to know!

Would this one be good?

Thanks again for the response!!! I know that this may have been asked in some other places

yes the dvi option link will do the job :)

What active adapter are you using? I have two of these in conjunction with 2 passive DisplayPorts and I have no issues whatsoever.

My card has mini DisplayPort, and my monitor has DVI or HDMI.

I'm from Canada, so going with this one:

/EDIT: There's even cheaper ones here:

I have a 5870 2GB Eyefinity 6 edition, and yes, you'll need an active adaptor. I purchased this one for my third monitor, and it works perfectly.

I doubt a new gpu is 32 dollars.

Thanks! I'm not sure that i'll lower it though. I'll update my post that i'll include 2 mini display to dvi and 1 active mini display to DVI adapters. You need the active connectors that support the "eyefinity" setup, otherwise you won't get more than 2 displays with the 5870. Those adapters new look to be ~$28 a peice. If you find them for cheaper great! 3 more and you can get a full 6 monitor setup on a single card. I don't imagine you'd get it for gaming experience, considering the card is from 2010, but might run smoother than USB to display adapters.
