Actually, Super User has a multiple monitors tag: [**[multiple-monitors]**][1] (435 questions).  This is the tag to use for discussing setups where multiple monitors are being used simultaneously.  We use the [**[monitoring]**][2] tag for questions about monitoring software, but they can be easily confused so it's good to watch out for that.

Several of the existing **[monitors]** questions already have the **[multiple-monitors]** tag as well, and a couple of the others should have the multiple instead of the singular.  I've fixed those manually, and batch-retagged the **[monitors]** tag into [**[monitor]**][3].
