PCWorld reached out to Intel for comment, and received this statement: “Intel Display Power Saving Technology (DPST) reduces power consumption on mobile PCs by reducing backlight of the laptop panel while maintaining quality on screen. While your mileage may vary by laptop and use case, it’s safe to say that Intel’s power efficiency software doesn’t meaningfully improve battery life. Increasing the Power Efficiency level is supposed to reduce image quality, thereby increasing battery life, but in my case the opposite was true. To stop your laptop from changing contrast levels on its own, look in the Power Settings section and change the Power Efficiency level to 1. Intel’s Power Efficiency setting can cause drastic contrast changes depending on what’s onscreen. At the top of the screen, select the tab that says Power. Just ignore these and instead select the System tab on the left sidebar (or, if the app is running in a small window, the icon that looks like four squares). When you first launch the app, Intel will advertise a couple of gaming-related features. If you have a recent laptop with Intel inside, the Graphics Command Center app should be pre-loaded. Alternatively, you can find it by scrolling down to the ‘I’ section in your alphabetized app list. To launch the Intel Graphics Command Center app in Windows 10, just click the Start button and type Intel, which should bring up Graphics Command Center as the first option.
