Monitor/monitor stand worry

[Scandalized]

Ok so my worry is, I have recently purchased new ultra wide monitor, new mount to accommodate 3 monitors.

 

After about a month I've started to hear sort of loud ticks/clicks after about 20 minutes to an hour after use. Now my mind says it's just the heat dissipating n the plastic is shrinking n expanding, but another part of me screams it's all gonna fall down!!!

 

I do check the bolts etc are still tight and I have noticed the bottom monitor has gotten lower needs readjusting. And to top all of this off, it's a desk clamp style stand for the 3 monitors which is attached to a tempered glass desk.

 

Mounts etc are good for 15kg per monitor. But is it worth investing in a new way to mount these monitors in this configuration?

 

Here's a link to the monitors ok n question.

Yeah, I think its just the heat from using the monitors. If they were going to fall you would not have any warning lol.

I would be cautious about that.
