I'd been having troubles with my new TV. So, I went to the manufacturer's website, found a support email address, and sent an email describing my problem - basically, I was getting 2 seconds of blue screen when switching from an HD channel to non-HD. About 20 minutes later, I recieved an email:
Hi Fred,Now that's great customer support. I got a personalized email with specifc instructions on how to fix my problem in 20 minutes.
Please force your HD and SD channels to the same output resolution.
Thank you for contacting Syntax Technical Support.
Sincerely,
Joe P
