    I've asked quite a few retailers and many don't even know what it is? Reply

    At least I haven't seen any :( I'm sure we will post something here in AT when we hear about them Reply

    Not yet, looks like early next year perhaps. The MST (multi-stream transport) section of DP 1.2 had some revisions made, and the compliance spec for MST is just being generated. Should see MST prototypes at the DisplayPort PlugTest in November (including DP 1.2 hub devices), and then demos at CES. Reply

    Does this adapter just duplicate each display or can each display be driven independently? Reply
  • PyroHoltz - Wednesday, August 03, 2011 - link

    Obviously it would be two independent displays based on the bandwidth required. ~4.43Gb/s x 2 = ~8.86 Gb/s which is less than the required 10.8Gb/s for DP1.1a.

    If the breakout box was just allowing you to show the same thing on both HDMI connections it wouldn't require twice the bandwidth.

    I can't even find any monitors available which accept greater than 1920x1080 over HDMI. If you need to plug multiple 2560x1600 monitors into one DP why would you bother switching to HDMI to transmit the signal? Reply

    I see you guys really struggled to find something negative to say. The best you could come up with is that it doesn't support 2560x1600? Based on a silly bandwidth calculation?

    Monitors with that resolution are very rare to begin with. Very few of those have HDMI inputs. And those that do, generally don't support 2560x1600 over HDMI (which requires HDMI 1.3 support).

    So even if you own two Dell 3007WFP, or two 3008WFP, or two Apple 30" Cinema Displays, none of those will do 2560x1600 over HDMI. Not even over single-link DVI. And the idea that someone would want to drive those from a MacBook is pretty ridiculous.

    All in all it's a pretty stupid criticism.

    My goal was not to criticize, but to add something more than what other sites and Zotac released. That is one of our main goals: to provide more than just a rewrite of press releases and other stories. It was merely backup for my assumption that the adapter is based on DP 1.1a or earlier, as Zotac claims that it only supports up to 1080p.

    I am aware that most monitors don't support more than 1080p over HDMI but if Zotac supported 2600p over HDMI, one should be able to get HDMI to dual-link DVI adapters to be able to drive two 30" displays at 2600p. It's a small market but I still wanted to add something of my own to the article instead of rewriting the PR.

    This ia definitely a great product and the $50 price tag makes it even more appealing. In fact, I might buy one for my own use at some point.

    How do you know it is setup to allow the computer to have 2 video outputs for an extended display setup and not just a way to send the same video to 2 different devices, say a 42inch TV and a 24 inch monitor.

    Are you guessing or does it actually say that and how does it work, does it show 1 3840x1080 monitor in the control panel, or does it have software to make the monitors show up correctly.
  • sjael - Tuesday, August 02, 2011 - link

    In the product brochure thing on Zotac's site, it says "3840x1080 spanned resolution" so I'm guessing it will identify as a single 3840x1080 screen. It definitely doesn't (just?) mirror them though. Reply

    So theoretically, one could have 10 monitors hooked up to the ASUS 6970 ( using these adapters. I'd love to see someone test it just for fun. Reply

    I know a displayport splitter is able to be expanded to 12 displayports so you can connect six displayport splitters at same time. You can see it on Reply
  • stvcmty - Wednesday, August 17, 2011 - link

    The adapter probably uses an IDT VMM1402. The VMM1402 has a displayport input, and 2 DVI/HDMI outputs. It can combine 2 physical monitors into a single logical display attached to the graphics card.

    This is nothing new, the VMM1300 boxes have been doing it for a while. They have 1 displayport in and 3 DVI outs, allowing a 3 monitor setup. The big difference is price. The Zotac box is about 1/3 the cost of a VMM1300 box, and it does not need USB for power.

    So you could use this with two LCD monitors that have DVI by going from:

    1 display port to 2 HDMI by way of this adapter
    then HDMI to DVI cables to the monitors

    Still tons of LCDs sitting around with DVI but no HDMI or Displayport input so I'm sure someone will want to do this.

    "Unfortunately the HDMI outputs are limited to 1920x1080 which indicates that this adapter might be based on older, 1.1a or earlier, DisplayPort (DP) version"

    99,9% of the available displays don't support more than 1920x1080 on their HDMI inputs, even the 27" and 30" Dell screens.
  • -=Hulk=- - Wednesday, August 03, 2011 - link

    Sorry, not 1920x1080 but 1920x1200. Reply

    HDMI to dual-link DVI adapter might still work though, if Zotac supported 2600p over HDMI. See my earlier post in the comments, it was merely an observation and I'm aware that 1080p is pretty much what you get from HDMI anyway. Reply

    Hey all, I have a 2010 macbook air with 2 monitors that have only dvi connectors. If i use this adaptor and grab 2 hdmi-dvi cables, will I be able to operate split screens? Reply
  • Chizzel - Thursday, August 25, 2011 - link

    Will 2 dvi-hdmi cables connecting to 2 monitors function with this adaptor? Reply
