I have a late 2012, 13-inch MacBook Pro with Retina display. Apparently it has Intel HD Graphics 4000. I just bought a Seiki 50" 4k TV and would like to connect it to my laptop with as high a resolution as possible. I'm a programmer so I want the screen real-estate, don't care if the refresh rate is only 30 hz.
The Seiki TV comes with an HDMI cable, but when I plug that in, I only get 1080p (with 60hz).
This [1] person was able to get better resolution, but he has a 15 inch and a different graphics card.
I used this laptop with a different 27 inch monitor (one of the korean monitors on ebay) and was able to get 2560xforgot. If I remember correctly, I connected to the 27 using using DisplayPort, rather than HDMI.
If my laptop can't do more than 1080 output to the 4k monitor, I'm willing to upgrade my laptop. I'd like to stay at 13" rather than upgrade to a 15". Are there 13" MacBook Pro with Retina display which can output 4k to my tv? Do I have to get the latest or is there an older model which will do what I want?
[1] How can my mid-2012 MacBook Pro Retina 15 run a 4K panel at 30Hz over HDMI?

What's officially "supported" and what's possible don't match. I have a late-2012 rMBP and got 4K out of it at 30Hz.
I took a screenshot as proof:
Just a normal mini-displayport<->displayport cable was used.
