In this [topic="7919"]thread[/topic] Digger cautions against pulling apart a touchscreen to wall mount it. I was wondering how many others have actually done this? Is it something that should be avoided without question? Please give me your opinions.
I have done several Open Frame type conversions to wall mount. I have not read the other posts, but here are a few thoughts:
1) ventilation - remove all of the insulation above the mount, and consider a small vent or grill at the very top near the ceiling. This is especially true if its large, or an older model. Older touch monitors tend to have less efficient inverters to power the backlights.
2) power - do not mount your AC/DC power brick (or wall-wort type) inside the wall These "consumer" type power supplies need to be in an open area. Instead, extend the DC side wire to the nearest AC plug. You can use a blank wallplate with a drilled hole and low voltage backbox to bring the DC wire through the wall near your AC outlet. Use a voltage drop calculator to determine the maximum voltage drop over your gauge or wire and distance. Most monitors will handle a small voltage drop without problem.
3) dust - if the touch glass is not completely sealed against the LCD glass, try to seal it off before you do the final mount. Else over time dust will creep into the gap.
