Agreed, but the point was that LCDs meant for such use/abuse are often specially designed.
Maybe, but placing a TV in the same room or between two loudspeakers is not the same as "using the TV as a baffle wall". I was referring to the latter, also mentioned by mountainman in post#9, immediately above where I first wrote. If the TV is itself the baffle wall, then it will be subject to direct vibrations / resonances from the cabinets and subwoofers (not good). The same is equally applicable to any loosely fitted panels / supports within the baffle wall.
Please note that the cases from the linked page are always and in any case of extreme events such as "extreme heat or cold, dust, moisture, or water" and of mechanical kind: even with all my good will it does not seem to me that those harmful conditions have nothing to do with the music that comes out of the speakers.
I agree that if the LCD screen touches the speakers or it is rigidly in contact with them it is not the best condition possible, but even in that case I don't think anything should be done more than insulating it mechanically from the rest of the world perhaps with a simple tape of adequate thick rubber.
But if they don't touch themselves then - just for the reasons already said - the issue doesn't even arise.
Just as a funny example this is a TVC with built-in subwoofer. 😉
