There's

- [tag:external-display], 121 questions

- [tag:external-monitor], 13 questions

As the two are obviously synonyms, and the first one is much more widely used, I suggest to:

- Merge [tag:external-display] and [tag:external-monitor] → [tag:external-display]

- Create a synonym [tag:external-display] ← [tag:external-monitor]
