BOOX Note Air sleep screen size and custom wallpapers
Updated September 23, 2026
Short answer
BOOX Note Air screen size
The BOOX Note Air screen is 1404 × 1872 pixels in portrait orientation (width × height). A sleep screen image at exactly that size is shown pixel for pixel, with no stretching, blurry scaling or black bars. BOOX makes several Note Air generations; check your model's specifications if the image looks cropped.
Tips for e-ink: use grayscale PNG, keep strong contrast, and avoid fine gradients, which can show visible banding on 16-level gray screens. Every InkMorning download is already rendered this way for the boox-note-air preset.
Set it in BOOX settings
BOOX tablets run Android with BOOX’s own launcher, and they support custom screensaver images out of the box. On recent firmware the option is under Settings → Desktop & Screen saver → Screen saver; older firmware names and places it differently. You can pick separate images for standby and for power-off.
- 1Download a wallpaper with the BOOX Note Air preset selected (1404 × 1872).
- 2Copy it to the tablet over USB, or download it directly in the tablet’s browser.
- 3Open the screensaver setting, add your image and select it.

Can the KOReader plugin change the BOOX sleep screen?
No. KOReader runs on BOOX as an Android app, and on Android the system, not KOReader, draws the sleep screen. The InkMorning plugin can still download and update images on the tablet for you, but you set the screensaver in BOOX settings.
