    I just purchased a brand new MacPro with thunderbolt 2 connections.

    I also purchased a new 27 inch Thunderbolt display.

    I got home, plugged in MacPro and then plugged up the TB display.
    I then plugged the thunderbolt cable from the Display to the MacPro.

    When I plugged in the display to the cpu ... nothing, blank screen,
    no backlight ... nothing at all.

    I then tried plugging the tb cable into all 6 ports available on the pro (still nothing).

    THEN .... I decided to see if the thunderbolt display would work with my MacBOOK Pro, which has thunderbolt capability. .... ok, so I plugged in TB Display to my macbook pro and it worked perfectly fine. So, that tells me the screen does have power and the cable does work .... on the display.

    So if it works on my macbook pro, why does it not get power and work with my Mac Pro?

    Oh - I also tried hooking up my LED Cinema display to the new Mac Pro and that worked perfectly fine .... so I know the MacPro ports are working since they gave light to my older LED Cinema display. They, however, will not give right to the new thunderbolt display.

    And no ... I am not hooking both up at the same time, but I do plan on doing so when I can just figure out how to get power to the thunderbolt display as a single monitor

    Help Please!

    Mac Pro, OS X Yosemite (10.10.1)

    And what has Apple support online told you or the Apple folks at the store where you purchased the equipment?

    Waiting on Apple support to reply online.

    Store I purchased from is closed for Holiday
    so I have not had a chance to talk to them yet.

    Did a lot of research and really haven't seen
    anyone else having this issue.

    However, I do see that a lot of people rate the
    TBD very low on a 5 star scale.

    Was also thinking about just ridding myself of
    this display and getting 2 new LG 34" Curved Ultrawides
    and putting side by side .... but they I don't like that
    they do not have built in webcams for my skype calls ;(

    If I can get this to work, i'll likely just keep it.

    Something seems wrong with your Mac Pro. While the Thunderbolt Display is arguably over-priced, it has one thing going for it, which is that it is the most compatible monitor you'll find with your Mac Pro. Does any other monitor you have access to work with your Mac Pro?

    you choose a inferior panel for an overpriced tag over a build in webcam, and it's not even that good of a webcam....i replaced my build in cam with a logitech c920 and the quality is so much better.

    Hey fellas -

    It is fixed. Someone on the mac support forums told me to
    do the following ... and it instantly fixed the monitor and woke
    it up:

    "Unplug your Pro and TBD from the wall. Let it sit for 1-2 minutes. Then connect your TBD to your Mac. Plug the TBD into the wall and also your Mac. Then try."

    Verrrry strange. Didn't think that would really work, but it did.


    I would prefer the LG Ultrawide Curved, for sure. But ...
    they have a pricetag of $1,300 each on amazon. They do
    offer more functionality and better options for ports. But,
    they are IPS and to my knowledge not the glossy finished
    screen. Both of which I do not prefer.

    Also, I already have a 27 inch Cinema that I am using to
    sit next to the TBD to have dual monitors. One ultrawide
    offers less realestate than both of my 27's together. So
    in order for me to really have what I want i'd have to buy
    2 ultra wides = $2,600. Where-as the TBD cost me 900 (biz discount)
    and I already had the cinema. So it is actually more cost
    effective for me to buy the thunderbolt.

    But I agree, I think the LG monitor is way nicer and would
    be mega awesome if I had two of the 34 ultra wide curved-s
    daisy chained side by side. But it'd cost an arm and a leg. =(

    And yeh - built in webcam for macs do suck. I may try the

    wait i'm confused, ur saying it like ips is a bad thing when ips is one of the best type of panels out there, don't forget your cinema display is also a ips.

    also the acer 4k 32inch was just on sale on newegg for 699, ips as well. prices for 32inch 4k will come down very rapidly in the up coming months, which confuses me even more when people are still buying the apple display for 800 bucks

    you should look around more, the dell 4k ips 60hz 27inch was on sale for 500 bucks couple weeks ago too.

    I don't get any light bleeding through on the cinema.

    And I read all this hype about how the IPS LG's have a pretty
    good bit of light bleed in the corners. So that was a turn off.

    And If I am gonna go any bigger than 27 inch, it needs to be
    on an ultrawide. I need as much realestate as I can get for
    what I do. and i'd prefer it to be in a way that allows me to
    put windows side by side by side.

    Good deal on the monitor on newegg for sure!
