I just bought Sony X800D TV and it comes with 2 hdmi ports that do 4k at 60Hz and 1 HDMI port that does 4k at 30hz. I have 2015 Macbook Pro 15" with iris pro IGP. As you guys probably know, this macbook support just HDMI 1.4 and it only does 4k at 30hz. I want to output 4k at 60hz and my TV only has HDMI, so I cannot use display port or thunderbolt from my mac. I'm wondering if I could use mini displayport to HDMI adapter to output 4k 60hz. I tried one adapter from Wal-mart with 4k label, but my mac doesn't even recognize the TV is 4k capable anymore.

P.S : I'm not sure if this is the right forum to ask this question. If it is not, let me know.

Indeed, you need to use the Thunderbolt port of your MacBook to output the signal. According to everymac, your MacBook is definitely capable of outputting 4k@60Hz.

Now, you need a Mini Displayport to HDMI adapter, which does support 60Hz at 4k. I found this one, and a customer's review verifies that it does work on his MacBook Pro 2015.

Also note, that you need a HDMI 2.0 capable cable as well.

  • I went with Club3d adapter so I can't comment on this. But if it works, then obviously it's more affordable option.

For whoever looking for a solution to the similar problem, I went with this club3d adapter. You will need to use SwitchResX software to force OSX to output 4k@60Hz. There are tons of online resources on how to create a custom resolution in SwitchResX, so I'm not going to post it here. Club3d is a bit more expensive than @NZKshatriya's suggestion. I would give it a try before buying Club3d.
