I'm curious, what are you hoping to accomplish by aggressively interrogating OP here?
He was pretty clear in his messages that the mounting likely failed, causing the display to drop. Even if this is a one off (I'm not spending my time searching for other cases), he's not hurting anyone with this thread.
There are plenty of possibilities here though. Does your garage experience broad temperature swings? I'm sure the monitor has a rated operating temp range and excessive temperature swings could brittle the plastic, along with UV exposure if it has ever been subjected to much of that. Similarly, if it ever got splashed/sprayed with certain chemicals often kept in a garage, that could weaken the plastic too.
Actually the OP stated that the plastic failed, not the mount.

My 2209 fell off it's mount when the case sort of crumbled due (a guess) to aging plastic. So perhaps we need to address "ageing plastic." I'm having issue with the desire of the OP to cast fault on Dell, when by all indications of others that have posted to this thread there is no history of this monitor having consumer issues not does a web search indicate any further issues with this model monitor.

I have reported this to Dell but don't think they took it seriously.]
I'm a mechanical engineer, one trained in failure analysis, and perhaps I like to do a proper study prior to placing blame. There are many potential causes, one being a resonance in the mount that causes vibration that fatigues the plastic. But without further examination, and in the instance of only this one reported failure, I would suspect that if a resonance induced vibration is the cause, then it is something the OP has done. Otherwise others would have reported the issue, which at present still remains a sample size of one.
