Frequently Asked Questions
How to check for dead pixels using black screen?
View the black screen in a dark room. Any consistently lit pixels on a black screen may indicate stuck or dead pixels.
Why use black screen for OLED display testing?
OLED displays should show perfect black by turning off pixels completely. Use the black screen to check for any light bleeding or pixel inconsistencies.
What's the best environment for black screen testing?
Test in a completely dark room for optimal results. This helps identify any backlight bleeding or uniformity issues in LCD displays.
How can I use the black screen for meetings?
Display the black screen with a custom message like "Meeting in Progress" or "Do Not Disturb" on your device. The white text on black background provides high visibility while consuming less power on OLED displays.
Can I prevent my screen from going to sleep?
Yes, you can activate the screen sleep prevention feature which keeps your screen active without requiring manual interaction. This is useful for displaying messages for extended periods.
How can I display messages on my screen?
Simply type your message in the text box and it will appear on the color screen. You can adjust the font size using the slider and the text color will automatically adapt to ensure visibility against the background color.
How does the screen sleep prevention feature work?
When activated, this feature prevents your screen from going into sleep mode by simulating activity every 30 seconds. This is particularly useful during presentations, when displaying important messages, or when you need your screen to stay on for extended periods.
