Seiki 4K tv

Hey Logan Im thinking of upgrading my tv (which I use with my PC), and saw that the Seiki 4k 39in was only 699USD. Well the description from amazon says it only has 3 HDMI ports, knowing that the ASUS 4k monitor had to use dual DVI set up to get the full picture does this HDMI input system fully support 4k? 

Yes, but only at 30Hz. I recommend looking into the Chinese 4k TVs, which can run up to 60Hz.
