Boox Screensaver Sizes: Every Model's Exact Resolution
There is no single Boox screensaver size — it depends on your model. The most common across the 4 current Boox models is 1404 × 1872 pixels, used by 2 of them. Find your model in the table below and export at exactly that resolution.
Boox devices run Android, so the sleep screen is set from the system settings rather than a special folder — you copy an image onto the device and point the screensaver option at it. That also means Boox models vary more than other brands: the range spans an unusually tall 1:2 phone-shaped panel on the Palma through to large 1:1.33 note-taking screens, so there is no single Boox screensaver size.
Watch out: Boox firmware changes often and menu names differ between models and versions, so the exact wording of the screensaver setting may not match any guide. Browse the device's own settings rather than following a menu path literally.

One Image, Several Boox Models
Boox reuses panels across its range, so a single correctly sized image often covers more than one model without re-cropping.

- Are Boox screens greyscale?
