Mini DisplayPort/Thunderbolt to DVI-D cables, 1440p

post #1 of 5
Thread Starter 
Hello, was looking around for a Mini Displayport/Thunderbolt to DVI-D cables and there quite a few with a HUGE price difference.

Someone I know wants to connect a Macbook Pro to a 1440p Korean monitor that only has a DVI-D Dual port. I've been searching around and some cables are $10 and some are $70, what do they need and what is the difference?

The $10 are single link DVI compatible only - so resolutions up to ~1920x1200. Resolutions beyond this will not be supported. You may find issues with older DisplayPort/MiniDisplayPort if they are not DP++ compatible.

The $70 cables are true Thunderbolt/miniDisplayPort to dual link DVI (don't let marketing fool you). These ones are fully compatible with the dual link DVI specification, and support resolutions above 1920x1200, such as 2560x1440 or 2560x1600 at full refresh rates.

For your use, you need the $70 adapter. Of the three linked, it is the only one that actually does what you want done.

Do you know of any cheaper cables to connect a Macbook Pro to a Korean monitor with only DVI-D that supports the full 1440p? Or the only option is shelling out $70 for one of them expensive cables?

The monoprice ones are the cheapest option.

Your other option is to buy a multi-input version of the Korean monitor that has DisplayPort.
