4k @60Hz with gtx 650 mini HDMI 1.4

[aspmotta]

Hello guys, I just got a 4k TV to be my new monitor and was not expecting to be able to drive it to 4k at 60hz with my ancient MSI GTX 650, but crazy news, I am!

How is this possible? Although I'm using a HDMI 2.0 cable I'm quite sure that my card's max resolution is 2560x1600 and has only a mini HDMI 1.4 output port. I'm confused, here's the proof:

Magic.

It is supported. But only at 24hz: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-650/specifications

Hi OP, Could you let me know how you connect your PC to the TV? Straight to the TV? or through a Receiver?
When I connect it through the Receiver, I can only do 1080p with my 4K TV. Same video card. Thanks.
