I've read something like 5 or 6 HN threads about a dumb TV, and without fail _this_ is always one of the replies.

Another benefit — advertising displays are also designed to be always-on and last much longer than consumer devices.

The other side of the coin? Because of the first two points, they are also rather cost-prohibitive.

Nevertheless, anyone know where I can pick up a good one?

I don't know how long they are supposed to last always on, but I have done a few always-on displays with cheap-ass consumer TVs. They have always been fine left on for a couple of years. I mean, some of them got turned off on weekends and stuff, but for the price of a commercial display, you can buy 4 cheap-ass displays, and just replace one if it dies. I've also seen lots of these commercial displays die as well... I just don't believe they are really worth spending the money on. Of course, this was back before every consumer TV was a smart TV. I dunno if you can find cheap-ass TVs that aren't smart anymore.

There are probably many places where the cost of sending a technician to replace the display is rather expensive.

Not if you steal one! Which has 3 great benefits, you get a free screen, wherever you stole it from no longer bombards passersby with intrusive advertising, and whoever though doing that was a good idea is now out the cost of their expensive screen.

Your local shopping mall late at night...
