If you think about it, you'll realize that his post telling us the model number was totally crucial to our understanding his problem. His first post did not have enough information for an example from a Samsung manual of the eventual solution, which took me fifteen minutes to find on the internet.

My first answer was, yes, smartassish, but matched the level of info in his question. After that, I think the idea of making a couple of rows of the TVs and using an IR remote was a pretty good solution! He wants to do a bunch of these at a time, so he'll have to get out a bunch of them all at the same time, so that's pretty practical.

Once he gave the model number, a google search provided the answer. Read my signature. I wrote it for just an occasion as this. I hate that signature, but it keeps being necessary to say it.
