Questions, answered.
Does this calibrate my monitor?
No. A gray surface can help with visual inspection, but accurate calibration needs suitable measurement equipment and software.
How do I leave full screen?
Press Escape or move your mouse or touch the screen to reveal Exit. Press F to toggle full screen when you are not typing in a field.
Does it work on phones and tablets?
Yes. If your browser cannot open true full screen, the color fills the browser window instead. Browser bars may remain visible. You can use portrait or landscape orientation.
Can this change my device brightness?
No. Screen dimming darkens the displayed color only. Use your device’s brightness controls to adjust the physical display.
What does Keep screen awake do?
When supported and allowed, it asks your browser to keep the display on while this page is visible. The status shows whether the request is active, released or unavailable. Battery settings and system behavior may override it.
Can I download a 4K background?
Yes. Choose 4K UHD for a 3840 × 2160 image. Images are created on your device and contain the selected base color only, without the dimming effect.
