>log in to commentHi DevHunt! 👋 I'm Chloe, creator of BlackScreen.VIP. I built this tool to provide a clean, instant, 100% ad-free full-screen utility for testing OLED & LCD displays (stuck pixels, backlight bleed, uniform color tests) or just keeping a distraction-free dark backdrop. Hope it's useful to you, and feedback is always welcome!

BlackScreen.VIP FAQ
Is this actually pure #000000, or just very dark gray?+
The tool renders true #000000 across every pixel; screenshots show all RGB channels at zero.
Will running a black screen really save battery on my device?+
Yes on OLED/AMOLED panels where black pixels turn off completely; LCD panels see minimal savings because the backlight stays on.
How do I use a black screen to check for stuck or dead pixels?+
Enter fullscreen (press F), scan the display from about 40 cm; stuck pixels glow colored against the black background, dead pixels appear on a white screen.
How do I exit the fullscreen black screen mode?+
Press the Esc key, or move the mouse to reveal controls; on mobile a single tap exits.
Can I download the black screen for offline use?+
Yes, you can export lossless PNGs at resolutions from 1080p up to 8K or custom sizes.
