From what I'm reading online it sounds like 4K displays like Seiki displays will work correctly with a late 2013 MBP or later. I have an early 2013 MBP and am not finding much of any evidence that a 4K display will work with this model. Will a 4K display work at 3840x2160 with at least 30 Hz on a early 2013 MBP? Does anyone have this or a similar setup that could provide feedback or any issues that have? I'm interested in an external display with a high resolution and 4K seems like the best option.
Yes, it is possible to drive a 4k Display with an early 2013 and even 2012 Retina Macbook.

Its possible with SwitchResX and this stuff. Mini DisplayPort 1.2 to HDMI 2.0a Active Adapter 4K@60Hz
I have a MBP, early 2013, and it's working with 60Hz + 4k.
There are many adapters out there, but be sure is 4k + 60hz active, otherwise will not work.
I have been using 4K monitors with an Early 2013 Retina Macbook Pro since August 2014, and have an issue which is consistent across both 4k Monitors - the screen will go blank for a few seconds sporadically. It doesn't happen often enough for it to be a big issue, but it can be annoying. Most of the time i run at 2560 x 1440, but i can go up to 3840 x 2160, both at 30HZ. Both of these require a good quality HDMI cable v1.3.
The monitors i have used are Samsung U28D590D and Asus PB287Q. The Asus gives a richer picture, but the Samsung is brighter.
On my early 2013 15" rMBP and LG 27UD88-W 27" 4K UHD Monitor, and SwitchResX, I tried mDP to DP, HDMI to HDMI, all 4K compatible cables, and finally active mDP to HDMI 4k 60Hz cable. I could not get 60 Hz on any cable at 4K.
(DP = DisplayPort. mDP = mini DisplayPort. rMBP = retina macbook pro)
This LG monitor has DisplayPort 1.2 and HDMI 2. has DisplayPort 1.1a and HDMI 1.4.
This was the last cable I tried: https://www.bhphotovideo.com/c/product/1616926-REG/ezquest_x40085_active_mini_displayport_to.html
The cable I'm sticking with is the Startech mDP to DP, and the HDMI cable I tried was a 4K Belkin HDMI cable from the apple store.
SwitchResX did help me get more resolution options than the standard display settings would. I am now using 2304 x 1296, HiDPI, at 30Hz. I think I've tried everything.
I think it's because the early 2013 rMBP is limited to DP 1.1a, according to Dell. Also according to Dell, late 2013 rMBP has DP 1.2, which should be able to do 4K 60Hz https://www.dell.com/support/kbdoc/en-us/000128111/4k-5k-high-resolution-display-support-by-mac-systems
And according to Wikipedia, DP 1.1a is limited to HBR, which is limited to 30 Hz at 4K / 3840 × 2160. https://en.wikipedia.org/wiki/DisplayPort
I'm not sure how the other commenters are getting 4K 60Hz, but I think I've tried everything, and the results I've got are in line w/ the specs I could find. I knew nothing about any of this 2 weeks ago, and this was what I found trying to figure it out.
