Nice, you should have no problems upgrading to el capitan now, 99% of software is compatible by now. And could almost guarantee thats the issue 🙂 

Keep us posted

Hey mate, no, I didn’t need to run any apps etc. just plug the adapter in, make sure the UHD Colour mode is on, restart both computer and the TV, also make sure your plugged your HDMI into the “DVI HDMI” input on your tv. 

In saying that, it’s highly likely not working because your still running Yosemite, alot of 4K support was added in El Capitan.  

 

Let me know how you go.

You can make everything bigger in OSX finder (text, spacing, the sidebar etc) but really depends on how adjustable your third party programs are that you use. 

I run my Samsung UHD TV & Thunderbolt Display both at 2560 x 1440 (retina), as the TV still renders at that at 4K and does not actually put out 1440p, so while I’m at a lower resolution from the computer, the TV stays on 3840×2160 at 60hz if that makes sense. It’s crystal clear (alot better than the oversized 1080p).
But if you wanted to work at 4K for video editing, photoshopping etc, then it definitely works perfectly.

For sure! I’ve added below a couple more higher res photos. Let me know if you need any more.
