I was in an electronic store this afternoon looking at 4k tv's (Im considering using one as a monitor for a gaming pc) My PC will be using two 780ti's in SLI on water, The guy in the store was adamant that if i got a high end HDMI cable it would support a higher refresh rate than 30fps. my question to you all is simply was he lying? will This tv http://www.currys.ie/Product/sony-bravia-kd55x9005bbu-smart-3d-4k-ultra-hd-55-led-tv/321909/6.9.0 run at higher than 30fps using its native inputs?
