Questions

Why does yellow reveal pixel problems?

Yellow uses both the red and green subpixels, so a dead subpixel shows as a color shift.

Can I download this as an image?

Yes. Choose a size and press PNG to save a solid yellow image, up to 8K if your device allows it.

Can I send someone this exact screen?

Press Share to copy a link that opens the page with your brightness setting.
