Using MacBook Pro 15' with 27 inch Korean monitors (2560 x 1440)? - Page 2

@kevinsbane:
On the link you provided, it says under the heading "A policy for Graphics Card":
It is not possible to connect with laptop and all Apple computers including Macbook.

Are you sure this will work with my MBP retina? I'll post the query to the seller as well, but I usually wouldn't be too sure of their technical savvy. frown.gif

I bought and returned three of the Apple adapters to use with my 15" retina macbook and all of them were defective. If you read around on forums you'll find there are a lot of issues with that specific adapter. The image would regularly flash and cut out, and when I say regularly I don't mean once every few hours, I mean within 10 minutes of plugging it in. It would also become fuzzy and I'd have to disconnect and reconnect to fix the issue.

I ended up finding a mini-display port -> display port cable and using that with a display port monitor and it works flawlessly. Probably not what you wanted to hear frown.gif

No, this is exactly what I wanted to hear smile.gif, an account of someone using a MBPr who got such a display to work properly. Can you tell me what monitor model exactly are you using? If you have a link as well, that would be just perfect.

@all: As kevinbane mentioned, and I confirmed by reading online, there are accounts of occasional problems even when using
the Apple adapter.
I am quite certain the Thunderbolt port is compatible with minidisplayport.

EDIT 2: The sellers do not know exactly what their display can and cannot do. That being said, most of the time they're right. In this case, their blanket statement concerning laptops mostly deal with the fact that most of the monitors come with DL-DVI connection only - and 100% of modern laptops cannot drive a DL-DVI signal natively and must rely on the finicky DP-DL-DVI adapters. But there is no technical reason that a DP capable laptop cannot run a DP capable monitor. The only reason I can think of is simply ignorance (and desired simplicity in dealing with complaints).

Thunderbolt ports are display ports with pinouts to PCIe. <--- Mac tech smile.gif

If the Monitor has DP, then use that. Works fine.

I'm using a samsung 970D which is kind of expensive for what you're looking for.

I can confirm that on all display port devices I've tried the thunderbolt ports have performed flawlessly. If the display port on the korean monitors works with other devices then I can't see any reason why it wouldn't work with your MBPr.

No, no, I know that *mini* DisplayPort is compatible with ThunderBolt. I was asking if you thought that just "DisplayPort" (and not *mini* DisplayPort) as mentioned in the item description in the link you provided, does in fact refer to mini-DispayPort (ThunderBolt) that the MBPr supports. If not, would I need a mini-DisplayPort to DisplayPort converter/adapter? Are *those* any good? smile.gif

As regards the seller's blanket statement about laptops, I thought the same as well... good to get confirmation from you!

Ah, that's the same price as the Apple 27' Thunderbolt, so it is indeed too expensive for me. Btw, is there any specific reason you prefer the Samsung model to Apple's, given that they have the same price?

Thanks for confirming the display port devices that you have seen work well with ThunderBolt ports, definitely useful to know! Makes me more confident about buying one of these Korean monitors and knowing that I'll be able to get it to work.

(Ah, my first post on overclock, and this has been a most helpful thread smile.gif)

This link (http://blog.fosketts.net/2011/02/24/thunderbolt-light-peak-pci-express/) says that Thunderbolt = mini DisplayPort + PCIe.
Is the term "DisplayPort" now almost synonymous with "mini DisplayPort"? confused.

Oh. In that case, miniDisplayPort is a DisplayPort with a different shape. Hence, DisplayPort is also compatible with Thunderbolt. You'll need a $5 minidisplayport to displayport cable.
