Today, I just got my Samsung HDTV Smart Adapter (the one specifically made for the S3) in the mail. I set up the connection according to the instructions, and my phone says "HDMI cable connected". However, the picture on my TV blinks on and off every 2-3 seconds. I've had the same problem with my previous adapter, which I thought to be faulty, so I conclude that the problem has to lie with my HDTV. Has anyone else had this problem, and is there a setting on my TV/phone that I need to adjust?
