CAC-1170 with MacBook Pro 13-inch, Late 2013

I own a MacBook Pro 13-inch, Late 2013 [1] and bought a Dell U2718Q Monitor 4k [2].

My MacBook has a single HDMI 1.4 port (that support 4k display at max 30Hz, [3]) and two Thunderbolt 2 ports, that can support Mini DisplayPort 1.2 adapters [4].

I want to buy the CAC-1170 adapter [5] that can convert Mini DisplayPort 1.2 to HDMI 2.0, as my monitor support HDR in the HDMI 2.0 port.

Do you guys know if I could get the 3840×2160 at 60Hz with this CAC-1170 adapter on my configuration? Or what could be the maximum resolution that I can get with this adapter on my configuration?

Good day malucelli,

Although Apple states that Mac Book Pro late 2013 should be able to output 4K at 60Hz over the Thunderbolt 2, htis link does worry me a bit:
That states it cannot. I suppose it all depends if the Graphics Chip inside can do it … which CPU / Integrated Graphics is in your system?

The CAC-1170 adapter will convert DP 1.2 signal into HDMI 2.0 signal at max 4K 60Hz, but that singal does need to come out of your system first …
CAC-1170 does not support HDR by the way.

Hi, so my current hardware is a 2,4 GHz Intel Core i5 with a Intel Iris 1536 MB for graphics.

I think that I won’t be able to get a 4k output with this current hardware configuration.

I did a little digging, and maybe this is a software limitation implied by Apple. There’s a patch [1] developed by the community that can be applied that (maybe) enable the desired resolution on older Macs (I know that’s procedure not recommended).

When my monitor arrive I will validate the configuration that I got and maybe try those options and I will return to post the results.

Did you succeed?

unfortunately not, the max resolution that I get with 60Hz is 2560×1440.. I even tried the mac-pixel-clock-patch without any improvement..
