Xteink X3 · 24-bit BMP

Xteink X3 wallpaper size528 × 792 px

The Xteink X3 sleep screen is a 24-bit BMP at 528×792 pixels. The X3 display is wider than the X4 (480×800), so images sized for the X4 show borders unless they are re-made at 528×792.

How it works

  1. The maker with a Kindle Paperwhite selected, the photo shown inside a to-scale device frame
    1

    Use the exact size

    528×792 pixels, portrait. Anything else gets scaled, padded with bars, or cropped by the device.

  2. Dragging a quote on the preview, with the center guide line snapped
    2

    Tune for e-ink

    An X4 image (480×800) is narrower and taller than the X3 screen. Re-make it for the X3 here and drag to choose what gets cropped, instead of letting the firmware scale it.

  3. The download button and the install steps for the selected Kindle
    3

    Install

    24-bit BMP: sleep.bmp in the SD card root, or several in /.sleep. Step-by-step instructions are under the download button.

The same photo dithered three ways for a 4-gray Xteink screen: Photo, Crisp and Poster
Photo keeps gradients, Crisp keeps whites clean, Poster flattens to 4 grays.

4 grays

Like the X4, the X3 panel shows 4 shades of gray. Pre-dithering here means the preview is exactly what appears on the device.

Several wallpapers

Put multiple BMPs in a folder named .sleep (or sleep) in the SD card root and a random one shows each time.

Common questions

›My X3 wallpaper has white borders

It was made for the X4 (480×800). Use 528×792 for the X3.

›The sleep screen didn't change

Check the name sleep.bmp, the location (SD card root), and that Sleep Screen is set to Custom.

›It looks muddy

Raise contrast and try the Crisp or Poster look. Busy photos lose detail at 4 grays; simpler images hold up better.
