Disclaimer
We want this site to be genuinely useful, which means being straight about what it can and cannot do. A browser filling your screen with a flat colour is an excellent first-pass diagnostic — and it is not a laboratory instrument.
1. General information only
Everything published on whitescreen.info is provided for general information and educational purposes. It is not professional advice about your particular device, and it does not create a service relationship between us. For a definitive assessment of a specific display, consult the manufacturer or a qualified repair technician.
2. What the colour screens can and cannot do
A full-screen solid colour is very good at revealing dead and stuck pixels, surface dust, backlight bleed and obvious uniformity problems, because a flat field removes the visual noise that normally hides them.
It cannot measure anything. It will not tell you your panel's true brightness in nits, its colour accuracy in delta-E, its gamma curve or its contrast ratio. Those require a colorimeter or spectrophotometer and proper software. What you observe here also depends on your display's own settings, its age, your room lighting and your eyesight. Treat the results as observations, not measurements.
3. No guarantee of outcomes
Techniques described in our guides — including rapid colour cycling or gentle pressure to revive a stuck subpixel — work sometimes and fail often. We describe them honestly, including their failure rate and their risks. We cannot promise any particular result on your hardware.
4. Risk of damage
Any physical intervention on a display carries risk. Pressing on a panel can crack it, create new defects, or void a warranty. If you choose to attempt a repair described here, you do so entirely at your own risk and we accept no liability for the consequences. Where a device is still under warranty, a claim is almost always the better route.
5. Warranty and pixel policy information
References to standards such as ISO 9241-307 and to manufacturers' pixel policies are provided so you know what to look for. Those policies vary by brand, product line, country and purchase channel, and they are revised over time. Nothing here should be read as a statement of your specific rights. Always verify the current policy with your manufacturer or retailer before making a claim, and note that return windows can be short.
6. Health and eye comfort
Bright, full-screen white or coloured fields at high brightness can be uncomfortable, particularly in a dark room, and may be inadvisable for people with photosensitive conditions such as photosensitive epilepsy or migraine with visual triggers. Use a lower brightness setting, keep sessions short, and stop if you feel unwell. Nothing on this site is medical advice; if you have a condition affected by light, speak to a healthcare professional.
7. OLED and display longevity
Displaying a bright static image for a long period can cause temporary image retention on OLED panels. Keep test sessions brief on OLED hardware. We are not responsible for damage arising from prolonged use of a static full-screen colour.
8. External links
We link to third-party pages for reference and verification. We do not control those sites and are not responsible for their content or accuracy. A link is not an endorsement.
9. Errors and corrections
We aim for accuracy and we review guides periodically, but errors happen and technology changes. If you find something wrong, tell us at hello@whitescreen.info and we will correct it and update the modified date on the page.
10. Limitation of liability
To the fullest extent permitted by law, we accept no liability for loss or damage arising from reliance on the information on this site. This disclaimer should be read together with our Terms & Conditions.
