Your wiki is not the center of Wikia, so even if you could prove that "everyone on that wiki" used Desktop XL, it would still be irrelevant.

But, as I previously mentioned, you are also making the assumption that "the resolution they play games" is the same as "the resolution they browse the web".

You mentioned triple monitors. Far more people have secondary laptops or tablets than triple monitors. In would go as far as to say the overwhelming majority of people who own a desktop computer in 2015 also have either a laptop, tablet, or smartphone - and some people use these secondary devices to look stuff up while their primary computer is running a game.

edit: It's actually pretty funny that you're trying to make this just about your wiki, as it's been said time and again that it's the narrow-mindedness of not considering others that is the reason behind this update.

 * People who play the game your wiki is about are not a representative sample of the wikia population
