1404 × 1872 Screensaver Size
1404 × 1872 pixels is the panel resolution shared by 5 e-readers from Rakuten Kobo, reMarkable, Onyx Boox and PocketBook. Because pixel dimensions are the only thing that determines fit, one image exported at exactly 1404 x 1872 fills the screen on every device listed below — no re-cropping, no black bars.
Mostly the large note-taking panel, shared by the reMarkable 2, Kobo Elipsa 2E and two Boox ranges. This is the one shared resolution where physical size differs across the group: four of these devices are 10.3-inch screens at 226 to 227 ppi, while the PocketBook InkPad 4 packs the same pixels into 7.8 inches at 300 ppi. The same file is therefore noticeably crisper on the InkPad, and detail that reads cleanly there can look soft on a 10.3-inch screen.
To crop a photo to this size, open the resizer and pick any device in the list below — or choose Custom Device and enter 1404 x 1872 directly. It runs in your browser and never uploads your image.
Every E-Reader With a 1404 × 1872 Screen
| Device | Brand | Screen | PPI | Panel |
|---|---|---|---|---|
| Kobo Elipsa 2E | Rakuten Kobo | 10.3-inch | 227 | Greyscale e-ink |
| reMarkable 2 | reMarkable | 10.3-inch | 226 | Greyscale e-ink |
| Boox Note Air Series | Onyx Boox | 10.3-inch | 227 | Greyscale e-ink |
| Boox Tab Ultra Series | Onyx Boox | 10.3-inch | 227 | Greyscale e-ink |
| PocketBook InkPad 4 / Color 3 | PocketBook | 7.8-inch | 300 | Greyscale e-ink |
Same pixels, different density: these models put the same 1404 x 1872 grid behind different physical screen sizes, so density ranges from 226 to 300 ppi. The file does not change, but the same detail is physically smaller and sharper on the denser screens.
One Image, 4 Ways to Install It
The image file is identical across this group, but each platform accepts it differently. These are the methods the devices above use.
Kobo Elipsa 2E
Kobo reads sleep-screen images from a folder you create yourself. Put your resized images in a folder named exactly `screensaver` inside the hidden `.kobo` folder, then enable the two sleep-screen settings.
reMarkable 2
reMarkable shows a fixed suspended screen rather than a user-selectable one. Changing it means replacing the image file on the device itself, which requires connecting over SSH or using a third-party tool built for that purpose.
Boox Note Air Series, Boox Tab Ultra Series
Boox devices run Android, so the sleep screen is set from the system settings — point the screensaver option at an image you have copied onto the device. Boox also runs KOReader, which has its own wallpaper setting.
PocketBook InkPad 4 / Color 3
PocketBook has a built-in standby screen setting. Copy your resized image into the device's storage over USB, then select it as the standby or power-off image in the device settings.
1404 x 1872 Screensaver FAQ
- Which e-readers use a 1404 x 1872 screensaver?
- 5 e-readers use a 1404 x 1872 pixel panel: Kobo Elipsa 2E, reMarkable 2, Boox Note Air Series, Boox Tab Ultra Series, PocketBook InkPad 4 / Color 3. They come from 4 manufacturers — Rakuten Kobo, reMarkable, Onyx Boox and PocketBook — because e-reader makers buy panels from the same suppliers. One image exported at 1404 x 1872 fills the screen on every one of them.
- Can I use one 1404 x 1872 image on all of these devices?
- Yes. Pixel dimensions are all that determine whether an image fits, and these 5 models are identical in that respect. The file itself needs no changes. What differs is how you get it onto each device — these models span 4 different setup methods.
- Do all 1404 x 1872 e-readers look the same?
- No. They share the pixel count but not the physical screen size, so pixel density differs: Kobo Elipsa 2E is 10.3-inch at 227 ppi, reMarkable 2 is 10.3-inch at 226 ppi, Boox Note Air Series is 10.3-inch at 227 ppi, Boox Tab Ultra Series is 10.3-inch at 227 ppi, PocketBook InkPad 4 / Color 3 is 7.8-inch at 300 ppi. The same file therefore renders finer on the higher-density screens. Detail that reads cleanly at 300 ppi can look soft at 226 ppi.
- Are all 1404 x 1872 e-readers greyscale?
- Yes — every model using this panel is a greyscale e-ink device, so colour in your source image disappears on screen. Convert to greyscale before you export and check the picture still separates into clear light and dark areas, because two colours of similar brightness merge into a single flat tone.
