Reddit reviews StarTech.com 3 Port Mini DisplayPort MST Hub - 4K 60Hz - Mini DP to DisplayPort Splitter for Multiple Monitors - mDP to DP (MSTMDP123DP),Black

For everybody that says this card is overpriced, some info: There are zero cards on the market that will allow you to support six monitors at once that come even close to the performance of this card. Not for $500, not for $5000 (that I can find). Instead, you would need to buy multiple cards to do this. The alternative is to use a display port hub, which limits the resolution of each monitor (such as https://www.amazon.com/Mini-DisplayPort-Multi-Monitor-Splitter/dp/B00JLRBC7S?th=1) or use monitors that allow chaining of displayport connections (again, limits the res of each monitor). For users that want full resolution and frequency on their monitors, this alone is worth the premium.

I have a little bit to add to this conversation. When docked and using 2 single MDP->HDMI adapters 1 into dock and 1 into SP3 I never experienced this issue. I thought I'd be smart and get a 3 port startech adapter. http://www.amazon.com/StarTech-com-MST-Hub-Mini-DisplayPort/dp/B00JLRBC7S/ref=sr_1_1?ie=UTF8&qid=1452608223&sr=8-1&keywords=mstmdp123dp

Now I am seeing the same issue as you plus sometimes it just refuses to wake up and I have to hold the power button down to get it off completely.

Docking and undocking doesn't seem to work as well as it did prior with the individual adapters either. I keep using the startech in hopes that an update will come and resolve these issues.

I run the latest debian stable, and I'm using two 1920x1080 monitors with displayport. I've had to buy an MST splitter, since none of my monitors had a displayport out to daisychain. I got this one from startech

The p27h seems to have a displayport out, so you shouldn't need this splitter.

I've had no problems whatsoever to configure it, worked in a plug-and-play way. Both Debian and Windows 10 support Multistream displayport just fine.

What resolution are we talking about? You could hook-up three 3-way splitters https://www.amazon.co.uk/DisplayPort-Multi-Monitor-Splitter-3-Port/dp/B00JLRBC7S?th=1 to connect 9 independent monitors to your 1080ti.

Ah - I hadn't considered putting them horizontally, I had pictured you doing a 2x2 screen setup.

I understand not wanting the laptop screen.

You mentioned very long horizontal screens. They exist, from several manufacturers. Whereas Mac laptop screens are usually in a 16:10 ratio (width:height), these are in 21:9, which is what cinemas use.

Some examples are the ASUS MX299Q, LG 25UM65, LG 34UM65, Dell U2913WM. That's just what came up from a quick search of "Ultra wide monitor" on Amazon. They're in some different sizes, but usually ultrawides are 2560x1080 in resolution.

I'm not sure if that's enough to fit all four decks on.

You could do two ultrawides, which should be more than enough. I think some software will let you divide a panel into two separate virtual displays, if that makes managing the decks easier.

Which Mac are you using? I'm guessing it's probably a MacBook Air or a non-retina pro, since you don't mention HDMI.

If you decide to opt for more than one display, it is possible to run multiple off just one displayport connection. You'll need a displayport hub, but make sure it's not just a splitter, but one that lets you run multi monitor. Something like this:

EVGA makes a displayport splitter that's quite popular and reliable as well.

Yes, as it has a DisplayPort.

I just got [this disployport splitter] (http://www.amazon.com/StarTech-com-DisplayPort-Triple-Multi-Monitor/dp/B00JLRBC7S/ref=sr_1_1?ie=UTF8&qid=1425579485&sr=8-1&keywords=displayport+splitter), yesterday, and it's working really well, especially with the dock. You might want to give that a try.

This is your only option outside of a USB to DVI or hdmi

Thanks Dan. Right now I have 2x Dell UZ2315H connected using a Mini-DP to DP cable, and also the Surface Book display as a third display. Those solutions there look...confusing? Couldn't I just get something like this and be ok?

I use this one on my SP3 dock:

works great, every once in awhile you gotta hit the button and reset it, but I think it's more to do with the dock.

Does this work https://www.amazon.com/StarTech-com-DisplayPort-Multi-Monitor-Splitter/dp/B00JLRBC7S/ref=sr_1_2?ie=UTF8&qid=1499548850&sr=8-2&keywords=mini+display+port+hub

I have this one: http://www.amazon.com/dp/B00JLRBC7S

But you can find it cheaper on eBay pretty regularly.

So, by your stipulations, your only option is to buy new monitors that support DP MultiStream but that's not cheap.

You're not going to find an adapter to power multiple displays that does not hook up to USB or external power. I don't imagine access to multiple screens is common on-the-go, so I don't understand not wanting a dock.

What I'm trying to say is, you're going to have to compromise on one of your requirements.

http://support.amd.com/en-us/search/faq/170 You're correct, I never ran into this issue before because I had a displayport AMD card last. Well that sucks lol. I'll have to go pickup a MST hub.
Thanks!

This is the Display port hub is anyone else runs into the same issue http://www.amazon.com/StarTech-com-MST-Hub-Mini-DisplayPort/dp/B00JLRBC7S

You can only have up to two non-DP monitors at a time IIRC. You'd need a DP MST to split the DP and then active adapters for each DVI monitor. Not necessarily cost effective but that's how it is.

While editing my post I've discovered that there is now a thing like you've described. This for example. I can get mine to mirror, but it won't recognize multiple displays individually. Is this standard behavior?

Oh wow, that's awesome. So something like this should work? https://www.amazon.com/StarTech-com-DisplayPort-Multi-Monitor-Splitter/dp/B00JLRBC7S
