EIZO FlexScan EV2720S
The EIZO FlexScan EV2720S's certified consumption is 42 kWh per year, which prices out to about $7.90 at the national average rate — your hours of use scale that directly. Efficiency-wise it's unremarkable in a good way: within 7% of the median certified computer monitor (rank 579 of 1482). The same unit costs $5.18 a year in North Dakota but $20 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
