Manage Duet Display settings

Duet Display offers a number of settings for the best user experience. You can change the text size, display the resolution, and select the frame rate. It is important to note that some settings will consume more battery power. Let’s take a closer look at the Duet Display settings.

1. Resolution and text

Duet Display allows you to set various parameters such as frame rate and quality. If your work involves reading in detail, choose a larger text. Reducing the text size allows for more screen elements.

2. Retina

The Retina setting scales up the resolution, or pixel density. In other words, this setting offers the highest possible resolution at the expense of battery life.

3. Frame rate and quality

In the frame rate setting, you can select either 60fps or 30fps. The higher the frame rate, the less lag and the smoother the transition. However, battery life is sacrificed.

Quality settings play an important role when mirroring your Mac display. The higher the quality setting, the less artifacts will be displayed and the higher the battery usage. On the other hand, normal quality is sufficient for general purposes such as browsing the web and checking email.
