ASUS XG49W

The ASUS XG49W's certified consumption is 133 kWh per year, which prices out to about $24 at the national average rate — your hours of use scale that directly. It sits near the bottom of the certified table — using 196% more than the median computer monitor (rank 1499 of 1530) — so the state you live in matters more than usual. The same unit costs $17 a year in Nevada but $70 in Hawaii — electricity rates, not the appliance, make the difference.
