4K cables??
Unless I missed something when HDMI cables came out they are capable of handling 3840. So why a push on $70 4K cables when my original ones work perfect.
This is interesting question and it lead me to think about the problem I was experiencing: - with Comcast X1 box it doesn't support 1080i/p resolution after TV is powered ON/OFF. I have to try with those cable, maybe with those cables the problem will be fixed.
I have already posted a negative review about this TV.
