An E Ink screen may briefly retain a faint trace of the previous page. A menu can leave a shadow behind, or a photograph can remain slightly visible after returning to text.
This effect is commonly called ghosting. Understanding the available refresh controls can help users choose a better balance between a clean static page and responsive interaction.
The appropriate setting depends on what the device is being asked to display.
Understand the residual image
E Ink displays use electrically controlled particles to form visible content. BOOX describes ghosting as residual information from an earlier image that can remain when the display transition does not fully clear it.
A trace that follows recent page content is different from a general claim that the panel is permanently damaged. However, a persistent mark should not automatically be diagnosed as normal ghosting either.
Begin by observing what changes. Does the mark reflect the previous page? Does a full refresh clear it? Does it appear only in one application?
These questions produce a more useful description than “the screen looks strange.”
Choose settings according to the activity
Reading a static book page and scrolling through a website create different demands. BOOX’s refresh documentation distinguishes modes intended for clearer static content from modes aimed at more dynamic interaction.
The company also notes that settings vary between monochrome and color devices and between applications. Mode names and available controls should therefore be checked against the specific device and software version.
Avoid searching for one setting that must be best for everything. A page of text can tolerate a different interaction style from a scrolling document or an image-heavy application.
Establish a clean comparison
Choose a page with small text and a few high-contrast elements. Perform a full refresh, then use that result as a reference.
Next, repeat the activity that produces the unwanted trace. Change one relevant refresh setting and compare the result using the same page and sequence.
This method is more informative than switching several settings at once. It helps distinguish an improvement in text clarity from a change in scrolling behavior or refresh flicker.
Write down the useful setting if the device offers many choices. A short note can save time after an app update or a reset.
Use a manual refresh when appropriate
BOOX documents several ways to trigger a full refresh, including a Full Refresh button in Control Center. Other supported methods depend on the device’s navigation configuration.
A manual refresh can be useful after closing a large menu or moving from a complex page to a long reading session.
It should be part of a comfortable workflow, not a repeated interruption that makes the device unpleasant to use. If the same application constantly requires intervention, revisit its refresh configuration and the type of content it displays.
Describe persistent problems precisely
If a mark remains after appropriate refresh attempts, record the circumstances for support: device model, software version, application, selected mode, and whether the mark changes with the content.
Avoid changing unrelated settings simply to keep experimenting. A consistent test makes the problem easier to understand.
The practical aim is a display setup suited to the task. For long reading sessions, clarity may deserve priority; for frequent movement through an interface, responsiveness may matter more. The available controls let the user make that tradeoff deliberately.
