The test was performed on four Surface Books (256GB disk, Core i5, 8GB RAM, integrated graphics) running Windows 10 (10586.318 th2_release). These computers were configured to the following settings, to increase consistency between measures and reduce tasks that may start during the measurement and interfere with the results, while still representing a realistic user setup:

While plugged in, each respective browser was navigated to Netflix.com and logged into the same account. The show “Nature: Animal Misfits” was queued and paused immediately on each browser. Each computer was verified to have brightness set to 75% (with ambient brightness disabled) and volume to 25%.
