Monitor Height Is a Neck Problem, Not a Screen Problem
If you've ever worked on a laptop on a kitchen table for a full day, you already know the feeling: a specific, low-grade ache at the base of the skull, radiating into the trapezius. That is not a mystery — it is a predictable consequence of reading a screen that lives 8 inches below your eye line.
The well-established ergonomic guidance is that the top of the screen should sit roughly at or slightly below eye level when you are sitting comfortably. Laptops, by physics, cannot meet this criterion; external monitors can.
This is the most reliably underrated upgrade in the home-office world. A $30 laptop stand or a $15 stack of hardbacks, used consistently, outperforms any amount of standing-desk optimization for the specific problem of neck and upper-back tension.
The rule is not perfection. The rule is: your eyes should be able to scan across the screen without your neck moving down.
