I am building a bar and have a couple spare LCD monitors that I have acquired. I would like to construct the bar with the screens under the bar oriented face up covered by a hard clear plastic or glass and linked to a dual video multimedia PC housed under the bar. Will LCDs function in that orientation for a good amount of time or will they not work after long? I would of course have plenty of ventilation and airflow through the area. I have only seen documentation on Ceiling mounting for LCDs, but never for floor mounting style. Any ideas?
Should work just fine. I suggest instead of just covering thiem in plexiglass, that you mount one piece of plexiglass across the LCD itself, and then mount it inside the bar side. That way the monitor is completely inside the bar but the screen acts as part of the bar wall. People will be able to see it and you won't have to worry about anything touching it (including drinks ;-)). I've mounted LCD's in just about every position in a lot of places (even INSIDE desktop computers). They're pretty easy.
There should be no issues as long as you have them sealed away from spilled drinks and a little ventilation. You will need more ventilation on the back of the monitor than on the front.
