Dell is often the most economic when it comes to power usage and the UltraSharp U3417W is no different at 100% brightness. However, we do have to mention the low brightness when uniformity compensation is turned on – because this is on out-of-the-box this is how we measure the power consumption. This does make it easier to consume less power than the competition that might be 100 nits brighter or even more. In short, the measurement at 150 cd/m² is not done without reason. As it turns out, the U3417W does not look as great here. The monitor is significantly more power-hungry than the Asus monitor.
