Black Screen FAQs
Does a black screen turn off OLED pixels?
Yes. Pure #000000 causes OLED and QD-OLED diodes to switch off individually, yielding infinite contrast and minimal power draw.
How do I exit fullscreen mode?
Press the "Esc" key on your keyboard or move your mouse toward the top of the window.
Can this help identify stuck pixels?
Yes, bright stuck pixels (red, green, or blue subpixels locked on) stand out prominently against a solid pitch black canvas.
