Just tell your boss about this quote, and change the $50,000 to whatever you're making.

Big monitors are the easiest way to increase white-collar productivity, and anyone who makes at least $50,000 per year ought to have at least 1600x1200 screen resolution. A flat-panel display with this resolution currently costs less than $500. So, as long as the bigger display increases productivity by at least 0.5%, you'll recover the investment in less than a year. (The typical corporate overhead doubles the company's per-employee cost; always remember to use loaded cost, not take-home salary, in any productivity calculation.)
