Late 2013 27" iMac - 4k60Hz Possible?

5 replies

Hello,
I have looked through the postings but I haven't seen anyone specifically mention this model.  I currently have a non-Club3D DP to HDMI 2.0 adapter but the best I can achieve is 4k30Hz.  My iMac has the quad core i7 along with the GTX780M...would one of the Club3D adapters get me to 60Hz?

Hi Bullzie, that would depend on what outputs you have on your system.
Thundebolt 1 for video signal is the same as Displayport 1.1a which does not have enough bandwodth for 4K 60 Hz signal ...

So please please check if your system cna actually output 4K 60Hz ... because i think not

It is Thunderbolt 1.  Ok, at least now I know to quit looking for a solution.

Thanks!

We never stop looking for solutions at Club3D !
However this CAC-1070 Adapter is not your solution to achieve 4K 60Hz.
Your iMac has USB 3.0 ports right ?

Yes.  I saw your USB 3 solution but it looked like it only did 4K 30Hz.

True you saw that correct.
However if we can test your patience a bit than we will be able to offer you something you might not have seen yet ...

or CSV-1477: http://www.club-3d.com/index.php/products/reader.en/product/usb-a-t…

These products will work on any Host System with USB 3.0 port also MAC, and will enable you to connect 2 x 4K Screen at 60Hz to those systems !
Product are expected to become available second half of June.
Pricing should be about 100,- USD end-user without VAT for both.

This way you can use your system for years to come wihtout missing out on the new 4K screens at 60Hz :-)
