Frequently Asked Questions

How to test monitor color accuracy with red screen?

Compare the red screen across different viewing angles. Check for any color shifting or brightness variations that might indicate display quality issues.

Why use red screen for gamma testing?

Red is particularly sensitive to gamma settings. Use the red screen to fine-tune your display's gamma curve for optimal color reproduction.

What should I look for in red screen quality testing?

Look for uniform color distribution, no pink or orange tinting, and consistent brightness across the entire screen.

Can I display text on the red screen?

Yes, you can display custom text messages on the red screen. The text color will automatically adjust for optimal visibility against the red background.

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.
