Hi Folks,

Need a little help here. I have a new Sony NX810 with a new PS3 console connected with hdmi. When the PS3 is connected to the tv via the ARC HDMI Port, it works for a while and then the screen flashes and the picture goes grainy.

All work fine in the other hdmi ports. Does the ARC hdmi port have to have a 1.4 hdmi cable to work correctly? Since PS3 is only 1.3 hdmi should I not even connect it to the ARC port?

Trying to narrow down the problem and hope that my brand new tv doesn't have bad hdmi ports right out of the box.

Any and all help is greatly appreciated.

****This problem was resolved by replacing the current hdmi cable with a high speed hdmi cable. *****
