I work in Desktop Support for a large logistics company. A lady called me the other day wanting to explore why her 4th monitor wouldn't work. So I remote into the computer and immediately take a look at what card she has in the computer.

I can no longer remember exactly what the card was but I threw it's name into Google, went to the manufacturer website, and saw in its hardware specs that it supported a maximum of 3 screens.

Boom. There's our answer. Your hardware is limiting your experience.

That didn't shake her.

"Could we try updating drivers? I have the CD for the computer?"

Me: no, that will target the entire machine and it isn't a driver problem.

Some time goes by and my headset rings again. I answer. It's her... This time she's wondering why only one of her screens is working as she replaced the graphics card.... I have absolutely no idea where she got it from. But now she wants to update these drivers to "make it work".

I explain there are limitations to these things and that whatever she stuck in there is more than likely not compatible with the rest of her system

"Well can you check?"

Soon after this I just explained that 3 screens will be her maximum and she hated it.
