    Hi,

    I've been unable to get this important question answered...even after calling Microsoft and I can't find anything online.

    I need to know if the mini DisplayPort is v1.1 or v1.2. Does anyone know and/or can point me to any documentation?

    This is important to me because I am interested in an external monitor that has a DisplayPort 1.2 port and I want to take advantage of the daisy chaining feature provided the 1.2 specs.

    Thanks!

    Hey Nuspieds,

    i checked on that too, but was equally unsuccessful.

    But here's a suggestion: Why don't you take a different approach to this?
    For example: Besides MultiMonitor chains, is there a difference you could simply test?

    If not, why don't you take a shot and ask at BestBuy if they could try to hook up 2 monitors with DP1.2 to he Surface. There should be a few monitors at BestBuy?

    I don't know where you're at, but I couldn't possibly envision the Best Buys around here going through that effort! :LOL: Sad, but true. Just yesterday I was there and was looking for a USB 3.0 cable and when I asked the associate, she didn't know and had to go consult with another. It's no wonder that after much research on the internet that I'm doing a lot of purchases via Amazon.

    But your point is well-taken because I will not be investing in that monitor if I am not going to get out-of-the-box 1.2 support from the Surface Pro. I'm completely baffled as to why this isn't documented and cannot be answered by MS customer-facing representatives.

    im german so im neither accustomed to BestBuys nor to local Microsoft Stores. :)

    Same here. If you can't get the info by testing it (i don't know if the alternative - MS Stores - have the opportunity equipmentwise) you could contact(twitter?) Panos Panay the Surface "creator" - he should at least know the answer. But it appears to me a questions of whether he replies to your request or not.

    Anyway it speaks for itself that customers have to reach out to devs of MS to get the information they are looking for.

    Yes, it does! I am totally perplexed as to why that information isn't published on the Technical Specs page.

    Thanks for the additional info and if he responds, maybe I will finally get may answer.

    Display Port 1.2 was approved by VESA late 2009. It would be illogical for Microsoft not to adopt the 1.2 specification, but what do I know. :)

    Hmmm...since it is that old, then that gives me hope! 

    But, seriously, you never know. The consequences for me are very significant; the monitor I will be purchasing has a pretty hefty price tag but I'd use another strategy altogether for v1.1.

    Thanks, though, because although I am still searching for a confirmed answer, your info gives me hope that sticking with my strategy might be worth the risk if indo not get that answer.

    Anyone know? Is the Surface Pro equipped with a DisplayPort 1.1a or 1.2 port!?

    No one at Surface Support can answer this question for me. I have not been able to find it online either. Anyone?:angry:

    It interesting that they chose to go DP and then 1.1 at that. It was probably one of those things that was readily available at time of production. Disappointing none-the-less. I would have liked to see a flagship product carry the newest technology.

    So the DP 1.2 monitor I want to buy is almost about to be released. It makes no sense for me to spend that type of money if I'm not going to get the expected benefits and results.

    I went online to MS Support and told them this and that I needed an answer, as it has significant repercussions.

    The agent told me that they do not have that information and my case was escalated up and that I should be getting a call in 3 to 5 business days. That translates to this week, so although I've lost faith, let's see what happens.

    I asked them during 2 separate, unrelated, support calls and neither tech knew the answer. One put me on hold over and over and spent 25 minutes trying to find someone he worked with that knew the answer but was not able to get me a definitive answer.

    As I stated, incidents like that are the reason I lost faith.

    But on the chat yesterday (as futile as it may turn out to be), I told the agent to find a technician or engineer or whomever to get this answer. I mentioned that just as it doesn't make sense to just say "USB support" without indicating 2.0 or 3.0, neither does it make sense to just say "DisplayPort" as there are significant improvements. That point seemed to have resonated, but then again, the matter ended up being "escalated." To me, this isn't something that needs escalation; doesn't anyone there have a schematic diagram or something?!

    In another post, someone mentioned that the 1.2 specs were released in 2009 and that it wouldn't make sense that MS would use the old spec in a 2013 product. But my response was, "you never know," because you who knows for how long this thing has been in R&D and other technical factors that may drive them to use 1.1a. However, my personal and selfish recommendation would be even if they started with 1.1a support, then when 1.2 came out, they should have adopted it, due to Windows 8's robust support of multiple external displays and the Surface Pro's single DisplayPort.

    As you stated, it's unfortunate and, so, I've started to prepare to bite the bullet by ordering the accessories necessary to connect both of my monitors to my USB hub. My preference would be to use the DP 1.2 daisy chaining capabilities, but it seems like I'll have to wait for that. Oh well! I just hope that both monitors do not eat up too much bandwidth away from my USB-Ethernet connection.

    The SP uses the Intel HD4000 GPU. It supports DisplayPort 1.1a and is capable of supporting three displays (built-in LCD, DisplayPort, video via USB 3.0 to external "dock")

    Folks,

    I was completely flabbergasted not only to have received the following email, but also by its contents! :)

    I just received it and so I share with you all (slightly edited, for privacy purposes):

    "Interesting," to say the least, no? :)
