Why make my screen black?
Save energy
Making your screen all black saves energy. This is especially true on OLED screens, where black pixels actually turn off.
As a prank
You can use this as a prank to pretend like the device is dead.
Check for dead pixels
A completely black screen makes it easier to spot dead pixels.
Stealth mode
When you're in a dark room and you want to temporarily switch off the display light, this can be easier than putting your device into standby mode.
Meditation
You can use this to meditate. Feel free to play your favorite meditation song while you're at it.
Better than standby mode
You get most of the benefits of being in standby mode, with your apps still running in the background.
Check if screen is OLED
You can use this to check if your screen is an OLED one, as OLED screens don't emit light when set to black.
Use screen as mirror
Need to see who's behind you? A black screen can help you see reflections. Works better on glossy displays.
See the dust
Need to clean your screen, but don't want to turn it off? This will help you see all those dust particles.

Energy Efficiency: On OLED displays, black pixels use significantly less power, extending battery life.
Eye Comfort: Reduces eye strain, especially in low-light environments, by minimizing bright, harsh light.
Focus on External Tasks: Helps eliminate distractions when you're multitasking and not using the screen actively.
Prevent Screen Burn-In: Avoids static elements staying on the screen for long periods, especially on OLED or AMOLED panels.
Privacy: Keeps sensitive information hidden if you're momentarily away from your laptop.
You can clean a black screen better than a lit screen. Dust and fingerprints show well on the black screen.
Meditation/Relaxation: Useful when you want to use your laptop for ambient music or guided meditations without visual distractions.
Cooling: A black screen generates less heat on OLED displays, which can be beneficial in hot environments.
Extended Monitor Use: If the laptop is connected to an external monitor, a black screen helps avoid interference or confusion.
Software/Hardware Debugging: Sometimes required to check hardware issues like backlight functionality or to test software that controls screen output.
Prevent Sleep Mode While Listening to Video/Audio: Keeping the screen black allows you to conserve power and avoid distractions while ensuring the laptop stays active to play a podcast, audiobook, or music in the background.
