So, I'm planning to buy a 4K TV and obviously there isn't much content out there that is 4K, so I will most likely use my Mac as a source. Has Apple fixed the issue with 4K video in OS X via HDMI or do I need to find some other way to connect to the TV?
Under windows 8.1, it is said to be yes So I guess it's a software issue: Mavericks doesn't support it yet This is not strange because Apple's 4K display has not arrived yet
You'll get 60Hz 4K only over HDMI 2.0, which isn't really in use right now. Other than that, as mentioned above, DisplayPort 1.2 is your best bet. What inputs does your TV support? Regards Raptor EDIT: Didn't realise that the OP hasn't yet purchased the TV. If you plan to use the TV with a Mac for a while, definitely go for something that supports DisplayPort. Sony is no good (XBR series only supports HDMI). Panansonic, as recommended below, should do.
