Power consumption is measured at the wall with a blank Word document open and the monitor on as bright as it can go.
The G2460PQU used 30 watts while on full brightness with a Word document open. Compared to the Acer monitor in the charts, that is getting pretty close to double the consumption. But will it result in a brighter screen?
We use a LX1010B light meter to measure brightness in Lux. The monitor is placed in the center of the screen on a blank Word document with the monitor at full brightness.
Simply put, yes, the higher power consumption results in a much brighter screen. The G2460 is absolutely blinding at full brightness, but the brightness would be appreciated if I were working in a brighter room. At full brightness, you can see we measured 541 Lux coming from the screen.
We use this as a way to measure a monitor's efficiency. It is simply the monitor's brightness divided by its power draw.
As you can see above, the G2460 produces just 18 Lux-per-Watt, showing that the additional brightness comes at the cost of efficiency.
