How to test Kobo for dead pixels

Navigate to this page on your Kobo's built-in browser to run the test tool directly on the device. Kobo devices use E-Ink displays — start on white (reveals dark dead pixels) then switch to black (reveals stuck bright pixels).

Test in natural daylight with the frontlight at maximum. View from multiple angles — dead pixels on E-Ink can be easier to spot at a slight angle. Allow 2–3 seconds after each screen change before scanning, as E-Ink refreshes slowly.

Model-specific notes

  • Kobo Clara BW — 300 ppi E-Ink Carta 1300: dead pixels are tiny but sharp. Most visible in dense text passages.
  • Kobo Clara Colour — Kaleido 3 colour E-Ink: dead pixels may appear as stuck colour tiles. Test on red, green, and blue solid screens individually.
  • Kobo Libra Colour— Larger 7" Kaleido 3 panel: same colour test approach. The larger surface makes a centre dead pixel particularly distracting.

What a dead pixel looks like on Kobo

On Kobo E-Ink displays, a dead pixel appears as a small fixed dark speck that does not change when you turn pages or refresh the screen. A stuck pixel appears as a permanently bright or grey dot on a dark background — less common but equally a manufacturing defect.

On colour Kobo models (Clara Colour, Libra Colour), a colour filter defect appears as a stuck tile of the wrong colour — visible on certain solid-colour screens but not others. For a full breakdown, see the guide on dead pixel vs stuck pixel on E-Ink screens.

Rakuten Kobodead pixel warranty — what's covered

Kobo's 1-year limited warranty covers manufacturing defects. Dead pixel policy is not published and varies by region and support agent:

  • Canada and North America: generally more flexible — a single visible dead pixel in the reading area often results in replacement.
  • Europe and other regions: typically requires multiple defects or a defect in a prominent area before replacement is offered.

Contact Kobo directly at help.kobo.com. If you purchased from a retailer, contact them first within the standard return window — this is faster than going through Kobo's warranty process. For a full manufacturer warranty comparison across all e-reader brands, see our warranty guide.

How to fix a dead pixel on Kobo

E-Ink dead pixels cannot be fixed by software. If your Kobo is out of warranty, purchasing a refurbished unit from Kobo's website (Canada/US) or an authorised retailer is the most cost-effective path. Refurbished Kobo devices carry a 90-day warranty.

FAQ

Does Kobo have an official dead pixel policy?+
Kobo does not publish a specific dead pixel threshold. Support outcomes depend on the number and location of dead pixels, your region, and the agent. A dead pixel in the centre of the display — especially on a Libra Colour where the larger screen makes it more noticeable — typically has a stronger case for replacement.
I bought my Kobo from a retailer — do I contact Kobo or the retailer?+
Within the retailer's return window, contact them directly — it's faster. After the return window closes, contact Kobo at help.kobo.com. Most retailers pass warranty claims back to Kobo after their standard return period.
What's different about dead pixels on Kobo Clara Colour vs Kobo Clara BW?+
The Clara BW uses a standard E-Ink Carta 1300 panel — dead pixels appear as dark dots. The Clara Colour uses Kaleido 3 colour E-Ink — dead pixels can appear in the monochrome base layer (dark dot) or the colour filter layer (stuck colour tile). Both types are manufacturing defects covered by Kobo's warranty.
