I bought Gigabyte GeForce GTX 750Ti graphics card, that says prominently on the box "4k at 60Hz through dual HDMI".
OK, so I tried to connect this by 2 HDMI cables, to 2 HDMI inputs on my 4K TV, and what I get is two displays, of course, one on each input. I don't get ONE display at 60Hz.
Exactly how to connect this "4K 60Hz through dual HDMI" to a TV??
I found that Gigabyte has nonexistent customer support, no phone numbers I can reach, and no manual for this thing. Maybe that is why they make claims that may not be true. I don't know.
But if there is a way to get this to work, as it says on the box, can someone please explain it to me.

First at all your graphic card won't support 4k@60hz with 1 HDMI cable.
The meaning of 4k@60hz you mentioned is you using 2 monitor connected to the graphic card with 2 HDMI cable, meaning each monitor have 1920x1080@60hz. Only NVidia series 900 and higher will give you 4k@60hz with single cable.
Last, you can't give 1 monitor to display input from 2 HDMI cable at once!
