But I'll link to where other folk issue a complaint about that.

So there it is. Netflix's own code does that. Since Samsung doesn't code this, you know who to complain to next.

I recently decided to try streaming video as an alternative to network broadcasts. I have a Samsung DLP TV model HL-S6188W and a Roku 3 streaming player. I have a DSL broadband connection to the internet that provides an 8mbps download speed. There is an Ethernet hardwire connection from my modem/router to the Roku. The Roku is connected to a Denon A/V receiver via an HDMI cable, and the video is then transmitted from the receiver to the TV via another HDMI cable.
When watching Netflix, the TV will "blink" or black-out and then display a blue error screen stating "Mode not supported". The TV will then resume displaying the picture. The whole sequence lasts 2 - 3 seconds. It happens randomly--sometimes once every 20-30 minutes, sometimes once every 2 - 3 minutes. Note that the audio continues without interruption--it's only the video that is affected. And the problem only occurs when streaming video--it never happens when watching other sources such as DirecTV or blue-ray DVDs.
I have searched this forum and found quite a few threads about this problem, but I didn't find any that were recent posts and none seemed to have a definitive cause and associated fix. Is there anything new about this problem?
