DisplayPort MST hub released.

I haven't seen where anyone else has posted this. I saw it a couple of days ago. Run 3 monitors, up to 1920*1200 @60Hz, off of a single displayport connection. Better late than never, I guess, but it would have been great if it was around the time of Evergreen. 🙄

I clicked on the link for "buy now" and didn't see any helpful information on pricing or availability?

What is the pricing of this triple splitter adapter?

It is worthy of mentioning that the Dell U2413 has a MST Display Port Hub built in.

Any first hand real world experience with that? Looking at the specs, it has support for a standard and a display port out. And it's expensive 🙂?

Connectivity


1 Digital Visual Interface connectors (DVI-D) with HDCP
1 DisplayPort 1.2 (DP)
1 Mini DisplayPort 1.2 (mDP)
1 High Definition Multimedia Interface (HDMI)
1 USB 3.0 upstream port
4 USB 3.0 downstream ports
1 DisplayPort out
1 Audio out

DC power connector for Dell Soundbar (AX510)

The hub in the OP , needs external power also, and incurs a cost, so any information is interesting to total cost.
 
Going to try to get one to see if it can support multiple 2560x1440 monitors... but can't find one for sale in the USA...:colbert:

Read price was $160-$200. Not cheap enough to be a cost effective solution for gamers. I find it more interesting that the tech is finally coming around. It'll take full availability and competition to make the cost reasonable.

I can't think of any other reason for DP out. Interesting it's on the 2713H, 2560*1440 monitor. That would lead one to believe it was capable of driving that resolution.

From what I've read it won't do above 1920*1200 @60Hz. Evidently the single DP on the card has have the bandwidth to be able to drive the total resolution.

The hub tells the card that the resolution is 5760*1200 (for example) and then the hub segregates the signal to the 3 displays. Apparently this is why it needs power.

Are you sure, or is that speculation? That "hub tells card X resolution" concept seems to be how the old triple-head hardware worked for VGA and DVI.

However, I can't help but think that displayport is different, where there is no need to use tricks like that. I would think that it operates more like an extension cord that just passes the signals along, without emulating any kind of big resolution? For example, I think this displayport hub lets you run triple screens in extended mode, so they don't necessarily have to behave as one big display like you'd see withe the older non-displayport triple-head hardware?

*cough* integrate it into the monitor ports like dell did 🙂 Although, i'm sure that will be fairly cost prohibitive. The u3014 still costs north of 1400$ most of the time.

It actually does work. All of the 2013 model Dell monitors have MST built in and you can daisy chain 3 identical dell monitors together.

I just noticed this on the u3014.

the anand review of the 3014 indicates the dp passthru has issues with video to the downchain monitor. it isnt really a hub, it just lets the dp bus pass through to the next device in the chain so it can extract its package from the bus stream.

We are currently designing a DisplayPort only 2560x1440 monitor. It was actually suppose to release last month, but have delayed production to see if we were able to get newer technology/parts. This is all the information I can release without getting in trouble by my boss. But obviously it comes down to costs and price points...😉

From what I can find from research, this MST can support up to two 2560x1440 or two 2560x1600 monitors. If an additional monitor is connected then those resolutions are only supported for 1 of those monitors while the other two monitors has to be at 1920x1200 or 1920x1080.

I'm not sure. It's not speculation, it's what I had read posted elsewhere as the reason the MST couldn't do 3x 2560*1440/1600, for example. Made sense, but I haven't actually read it from a totally reliable source.

Thanks for the info. So, to be clear, can 3x 27" or 30" monitors be "daisy chained" together and do Eyefinity/Surround? It seems like you are saying it can't.

I put in email alerts at a few Dutch stores to let me know when they are in stock. I got my first alert today:
http://www.centralpoint.nl/kabelada...sion-mst-hub-3-1-dp-art-csv-5300-num-2052911/

Looking around, I found another shop that says they have some:
https://www.zercom.eu/index.php?dispatch=products.view&product_id=281549

Hopefully, they start showing up in the States soon.

I think MST can only do 2 27" or 30"...it's a Display Port 1.2 limit.

There's a good article about DisplayPort 1.2 & MST here:

http://www.anandtech.com/show/3987/...renewing-competition-in-the-midrange-market/3

It says:
a single DP1.2 link has enough bandwidth to drive 2 2560 monitors or 4 1920 monitors at 60Hz
