wasting your time. Get the adapter from club 3d. Believe me i tried everything for years. Works great for me on an lgub8000.

Good to know it works with DisplayPort! Too bad the TV i'm using now only has HDMI ports..

Well, that's what the Club3D adapter is for... DP 1.2 -> HDMI 2.0

Some people reported success on HDMI 2.0 with the pixel clock patch, but for most it doesn't work, so DP is the only option.

Since there's not a single Mac with HDMI 2.0 I wouldn't expect it to work well.

Tried the pixel clock patch -- didnt work (black screen) but I didn't rebuild kexts. Since I prefer not to patch the system, I'll try this: DisplayPort 1.2a to 4K HDMI® Active Adapter, White - Monoprice.com . $10 shipped, hope it works!

Note that the adaptor from monoprice says @30hz not 60hz like the Club3D

From the monoprice site:

• Supports HDMI resolutions up to 4K (3840x2160p @30Hz)

Pixel clock, for those of Us with Nvidia Maxwell with HDMI 2.0 Card in Yosemite/El Caitan, just run the IO command with SIP Disabled (csrutil status t verify).
Reboot, and Magic!

I have been searching for solutions to get my 4k TV @60Hz over HDMI port on my GTX 970 (1x HDMI 2.0, 1x DVI and 3x DisplayPorts) and as of an hour ago, I finally got it working on my Hackintosh PC (macOS Sierra). My TV is now running crystal clear at 4k 60Hz scaled down to 1080p.

I started trying about a month ago on El Capitan without doing any research and thought since HDMI only worked at 30Hz I might give DP a go so bought a random HDMI to DP conversion cable from a local computer store. Of course I ended up with failure so started doing some research. I then bought an HDMI to miniDP adapter by accident without noticing the "mini" on eBay and unfortunately within Australian eBay stores I didn't see any useful active adapters. This Club3D DP 1.2 to HDMI 2.0 active adapter bought on Amazon was just shipped to my office this afternoon (believe me, here in Australia we don't have fast shippings so getting something shipped internationally from the US which takes only a week I was really touched) and I rushed home to test it out. Started with bloody 30Hz with SIP disabled and "CoreDisplay-patcher.command" from GitHub applied and still no luck. I finally tried SwitchResX and added 4k @60Hz and restarted. Magic! I added scaled resolution 1080p to have the Retina Display feeling and SwitchResX did not let me down.

With all the above being said, the Club3D adaptor + SIP disabled + SwitchResX way is how I got mine working.

How did you go about adding the custom resolution to SwitchresX, did you use the simple settings or advanced?

Hi IAmSpectre, sorry for my belated reply. Hope the below screenshots can still help you. I took these ones from my SwitchResX.
