P2419HC, storing in cold environment?

I own a Dell P2419HC monitor. 

Since I've been working from home I've been working from a space at the back of my house that I heat during the day but not at night. The space is insulated and protected from the elements but it is not heated overnight.  In the winter months the temperature in this space can drop to minus 30c.

I bring my laptop in each night after I finish work, but I leave my P2419HC out there powered off. So far the temperature has not dropped below 9c.

Will anything happen to the P2419HC if I leave it in this cold space? Should I be disconnecting all of the cables and bringing it inside at the end of the work day every day?  

I am not sure if I am just being paranoid or if the cold will damage the monitor. Like I figure cars have LCD monitors built into them, and they sit outside in the freezing cold for days at a time and presumably nothing happens to those screens.
