    Hi everybody, I read that my mac mini could potentially run the screen I want to buy, but not sure if I need a thunderbolt cable, or I can just use the mini-displayport to displayport I currently use on my Asus 27" (which runs at 2560x1440).
    Because if the thunderbolt is not required, I could simply opt for the previous lg model, which is essentially the same of the new one but with no thunderbolt port

    The 2012 Mini won't be able to drive that display at its full resolution, regardless of connection type.

    Are you sure? Because I read on this forum that other users do, at 50hz, but it works

    As for your original question about the cable, the monitor supports both Thunderbolt 2 and DisplayPort so you should be able to use your DisplayPort cable. If you want to use the USB 3 port on the monitor, you'd need a Thunderbolt cable. However, since the 2012 Mini is Thunderbolt 1, there may not be enough bandwidth to run 3440x1440 and USB 3 at top speed.

    There are posts on the Internet that say 3440x1440 works up to at least 50hz on the 2012 Mini.

    So no need to have a specific Thunderbolt cable right?
    Good to know and thank you :)

    No not really interested in having the USB 3 port to work on the monitor, I just need the monitor to work, but thank you for the answer

    Hmm, I guess this has changed since I last looked into it. Never mind my first post then.

    Just to confirm that my new LG 34UM88C works just fine at 3440x1440@50hz with my Late 2012 Mac Mini i7

    Can anyone tell me what cable I need to go from the Mac Mini 2012 to my Dell 34" Ultrawide curved monitor? I can't seem to find a mini-dp or thunderbolt cable to mini-dp for the monitor. I have my regular displayport connected to a gaming system and want to keep it separate.

    If you have the LG 34UC98-W, from the Tech Specs on their website, you can use either a Thunderbolt 2 cable, something like the following:
    https://www.apple.com/shop/product/MD861LL/A/apple-thunderbolt-cable-20-m

    or you can use a Mini-Displayport to Displayport cable. I''m not sure why you're having difficulty finding such a cable. (A length issue, perhaps?)

    I don't know your last sentence means. If you already have your other monitor connected to the 2012 Mini using the Mini-Displayport port, there is only one Mini-Displayport/Thunderbolt port on the 2012 Mini.

    I have a Windows PC, that has a displayport cable from it's video card going into the displayport on my 34" Ultrawide curved Dell Monitor. The monitor has HDMI and a mini-displayport still left and HDMI on the Mini doesn't support that resolution. So the mini-displayport would need to be used.

    This allows me to switch inputs depending if I want the Gaming system or the MAC.

    So MDP to MDP. Male to Male.

    I found this cable which I believe would work.

    What you need is a mini-dp to displayport, like this one

    No, that cable works, even because I'm using the same to connect my mac mini to my monitor.
    The hdmi port doesn't have the bandwidth for that resolution, but the display port does, even if it's only 50hz

    I don't have the 34UC98, but my reading of the specs says that there is one DisplayPort port and 2 Thunderbolt2 ports. Thunderbolt 1/2 uses the Mini-Displayport connector so while a MiniDP-MiniDP cable will fit, the specs say that it won't work. I've seen reviews to that effect on Amazon. You would need the Thunderbolt cable as I mentioned in my other post. You should probably do some research because according to at least one person, they couldn't use the DisplayPort and Thunderbolt connectors and use Picture-by-Picture or Dual Controller software.

    I guess you didn't read what I said above. That cable does not work for what I need. I am utilizing the regular display port for my 1080gtx card in my gaming rig. The Mini will use the mini-display port.

    does everyone not read the full post? I don't own an LG. I own a Dell 34" Ultrawide curved monitor that has a min-display port input. This is the only topic that discusses using the resolution and reason I asked.

    My bad. I missed the Dell part. But I'm not sure why you posted on this thread, which deals with the LC 34UC98 instead of starting a new thread with the specific Dell model you have.

    The OP hit paydirt by post #9 and Mr. Pinstripes hijacked the thread on post #10. But that did not throw me. However, two things about the question did confuse me.
    1. Which Dell 34" monitor does Yankee512 have? (Dell has made several!)
    2. Why was there an inability to "find" a mDP to mDP cable? (Because Amazon!)
    Here are the port complements for two recent Dell 34" monitors. Is your Dell either of these? Any quality mDP to mDP (male/male) cable should work. The part that you found seems fine.

    Power connector


    MHL

    HDMI

    DisplayPort in

    Mini DisplayPort in

    USB downstream

    Stand lock​



    Dell U3417W FR3PK 34-Inch Screen Led-Lit Monitor


    1 DP 1.2 (HDCP 1.4)

    Thank you. Mine is the U3415W. For some reason when I was originally searching I couldn't find that cable and it might have been because I was searching for Thunderbolt to mini-dp. So, it looks like it will work then. Thanks for the info.

    You are welcome!

    But now -I- have a question. What is that Dell U3415W like to use? I have the U2515H and it is a fine display. From the specifications it seems as if your screen might be a curved twin version of my Ultrasharp monitor. Is that simply a 34" version of my 1440 display?

    Well, you have much more space on the sides, which it comes handy for software like photoshop/lightroom, or if you are a developer and you need multiple things to see at the same time

    I would say it's just a curved like you said of the 1440 display. It is very nice and feels the same distance at the edges. I had the LG 34 before and because it wasn't curved it felt like I was far away from the edges. It's much wider though, as it feels like two 24" monitors in one.
