Your iPad can serve as a portable second display for your Mac or Windows PC, giving you extra screen space on the go. Apple's Sidecar is the simplest option for Mac users, requiring both devices to be signed into the same iCloud account. Open Control Center on your Mac, select Screen Mirroring, and choose your iPad to enable a full-resolution secondary display.

Mac and iPad users also get Universal Control, which lets you share a single keyboard and mouse across both devices, including drag-and-drop between screens. Both devices must use the same iCloud account with two-factor authentication enabled.

Windows users can turn to third-party apps like Duet Display, which works on both Mac and PC but requires a paid license. Luna Display uses a companion dongle ($79) for more reliable wireless transmission and includes a headless mode for running a Mac mini without a dedicated monitor. Both solutions support Apple Pencil input, turning your iPad into a graphics tablet. Wired connections can help reduce occasional glitches.
