Flashing screen thru Soundbar
I just got the new Apple TV. Previously, with the old Apple TV, I was using the optical output to my sound bar. The new Apple TV has no optical out, so I have to run HDMI from Apple TV > Samsung sound bar (which has HDMI Mini input/output) > Sony TV. I purchased two 3' HDMI - to - HDMI Mini cables from Monoprice. This signal chain makes the screen flash from picture to green to picture about ever 1 second. The Apple TV works fine plugged direct into the TV. It only does the flashing thru the sound bar.
Do I have bad/cheap cables? Is there a hardware issue between the new Apple TV and a 3-5 year old sound bar?
Thanks in advance.
