Lenovo may be working on an Android tablet that doubles as a secondary monitor

The tablet market is propped up by Apple and its iPad, with only Samsung and Huawei really trying to compete with their own Android-based tablets. Another tech brand still pumping out new Android tablets is Lenovo, though they’ve mostly pivoted away from general-purpose tablets toward more lifestyle-focused devices like the Lenovo Smart Tab and Yoga Smart Tab. Lenovo used to make really interesting Android tablets like the Yoga Book with its E Ink keyboard. Now, leaked documents obtained by Android developer Till Kottmann (@deletescape) reveal that Lenovo is working on another Android tablet with an interesting concept. Possibly called the Lenovo Yoga X, this upcoming Android tablet may double as a secondary monitor for your various devices.


Developer Till Kottmann discovered a few internal documents that outline the “second screen UX wireframe” for the Lenovo Yoga X device. The document that they found contained a few mockups of what the tablet could look like, as shown in the featured image above shared by Evan Blass (@evleaks) on his Patreon page. Till Kottmann also shared the document with us, revealing what the purpose behind this tablet may be. One of the slides mentions how the tablet can be used as a secondary screen for other devices such as laptops, smartphones, or a Nintendo Switch. This is accomplished by connecting a device to the Yoga X through a micro-HDMI cable. Once connected, the tablet can switch to its secondary display mode, pausing any ongoing audio playback and locking the Android OS behind the user’s PIN/password. When nothing is connected to the Yoga X, the device can be used as a regular Android tablet.

There are a couple of other neat integrations when the Lenovo Yoga X is used as a secondary display. For example, when entering the secondary display mode, the Android system brightness and system volume levels will be used. Pressing the tablet’s volume buttons to adjust the volume will show a volume indicator on the display even if the Android OS isn’t showing. The user can control whether audio is output from the tablet or other available output devices. Touching anywhere on the screen will display the brightness adjustment, power, and output device settings.

The document that @deletescape uncovered only reveals Lenovo’s plans for the Yoga X’s secondary display mode. Thus, we don’t have any information on the specifications, pricing, or availability of the Yoga X. It’s possible that this document pertains to a concept product that has since been canceled, but we’ll keep an eye out to see if we can find more information about this tablet.
