Possible fix for HDPC with Westinghouse HDTV's
I sell devices like the Microsoft wireless display adapter to many customers. I was just helping a customer troubleshoot the black screen issue with a 46" Westinghouse HDTV. It would say connecting and the TV would go black, but it would show that it was connected on his Surface Pro 3. I asked him to try it on a different tv, Which was a Visio. And MicrosoftWirelessDisplayAdapter work fine. After reading a few Forms about the Westinghouse TV, I knew I was in HDCP issue. I asked him if he tried using a different HDMI ports on the TV, he had tried all of them except the first one. So when he pluged the adapter into the HDMI 1 port, any attempted to connect again. He had no problem at all! I later read that Westinghouse only as the HDCP active all on one or two HDMI ports on your TVs. So if you're getting a black screen or having an issue connecting, try using the HDMI 1 port.
