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

post #1 of 34
Thread Starter 
Does anyone have experiences using one of the 27 inch Korean monitors 2560 x 1440 as an external monitor with the 15' MacBook Pro with Retina Display?

If so, please share your experiences and any suggestions/recommendations.

In particular, many of these monitors only have a dual DVI-D output, while the MBP has HDMI 1.5 and Thunderbolt interfaces. Will the cheap (~ US $ 10) DVI-D Dual Link 24+1 pin (25 PIN ) to HDMI converters that are available online help connect the laptop to the monitor, while driving the monitor in its native 2560 x 1440 resolution?

A display port -> dual link DVI will work fine for it and provide the needed resolution thumb.gif

Do not get a korean monitor for your rMBP without DisplayPort. You can use a DP->DL-DVI adapter, but those are expensive (min ~$50; if it's cheaper it's probably not a DL-DVI converter) and notoriously finicky. Headaches all around - spend the extra $50-70 on a real DisplayPort monitor instead of the adapter.

It will work - I doubt it will work "fine". Every post I ever hear about DP->DL-DVI adapters has been about headaches and minor problems and things just not working all the time.

Hmmm.... and what about the HDMI to dual link DVI convertor (the MBP Retina has HDMI 1.4 interface)?

HDMI to DL-DVI converters don't exist. Well, that's just my impression actually, I'm not certain about that. However, I am certain that, if they did exist, then they will be just as expensive as DP->DL-DVI converters.

Beware of cheap HDMI->DL-DVI converters - they are definitely passive, and they will not work for 1440p resolutions. HDMI is compatible with SL-DVI, but not DL-DVI.

@kevinsbane: thanks, exactly the information I needed.


However, I do want to purchase one of the the Korea 27' 2560x1440 monitors, because I'll save at least $500 on the price compared to Apple/Dell monitors with the same resolution.
Would using the 100 $ Apple Mini DisplayPort to Dual-Link DVI adapter would be my only solution? Or should I go for slightly cheaper alternatives (50 $ and upwards, I think)?

@kevinsbane: when you spoke of the possibility of problems with using an adapter, does that include the apple adapter I just mentioned?

Pretty sure that the models without built-in scalars can't be used with integrated graphics whatsoever, regardless of the laptops connectivity ports. Not sure if active conversion would change that however.

 

Had might just be in your best interest to get the $50-100 more multi-input models as that had might spare you the trouble.

Yes, the problems apply to the Apple adapter too.

Forget getting a barebones monitor - get one with DisplayPort, like this one. You will be better off for it than trying to mess around with DP->DL-DVI adapters. Yes, it'll be slightly more expensive, but you'll also get a more functional monitor out of it.

Your best bet will be to get a DP-DLDVI adapter so that you can have full output of 2560xwhatnever if you are insistant on using a nice Catleap.

Hope that helps.


EDIT: If you are going to be using the Apple adapter, then you will be fine.

Ah, I see what you mean. So these Korean types come with DisplayPort natively as well. And just to be sure this is *mini* DisplayPort compatible with the ThunderBolt interface, right?

@all: As kevinsbane mentioned, and I confirmed by reading online, there are accounts of occasional problems even when using the Apple adapter.
