Questions and answers
Can I use a white screen as a light?
Yes. Turn the brightness to maximum and go full screen: a laptop or tablet makes a soft front light for video calls, and a phone works as a small fill light for photos. Other colors give a warmer or tinted light.
How do I trace a drawing with my screen?
Open the white screen on a tablet at full brightness, lay the drawing on it and a thin sheet of paper on top. Keep “Keep the screen on” ticked so the display does not dim while you trace.
Does a white screen damage the display?
No, showing white is normal use. On OLED screens just avoid leaving the same bright image on for many hours every day.
Can I use it to look at X-rays or film negatives?
Yes, as a simple light box: full brightness, full screen, and hold the film flat against the display. Turn off night light or blue-light filters so the white stays neutral.
Does a white screen help to clean the monitor?
Yes: dust, smudges and streaks stand out on white. Find them here, then turn the monitor off and wipe gently with a dry microfiber cloth.
My iPhone screen turned white. Is that this?
No, that is a fault. Force restart it: press volume up, then volume down, then hold the side button until the Apple logo appears. If it stays white, contact Apple support.
How do I check for dead pixels?
Go full screen and press the arrow keys to cycle through black, white, red, green and blue. A dead pixel stays dark on every color; a stuck pixel stays one bright color. Look closely, section by section.
