Detailed explanation-1: -Occasionally, a laptop screen’s hardware can fail. If your screen is getting increasingly dim as time goes on, the liquid crystal display may need a new backlight or need to be replaced entirely. You can check by connecting an external monitor to your computer and seeing if the display is also dim on the monitor.
Detailed explanation-2: - On Android: Settings > Display > Tap the slider next to Adaptive brightness and switch it to the off position. Then, adjust the brightness bar until you’ve reached your desired level of brightness. Assuming your display isn’t damaged, the most common culprit for a consistently darkened screen is power-saving mode.
Detailed explanation-3: -The primary reason you get no display on your PC could be damaged or loosely connected cables. Other reasons may include incorrect display configuration, faulty or problematic GPU or RAM, incorrect BIOS configuration, faulty peripheral devices, or damaged PSU (Power Supply Unit).
Detailed explanation-4: -If you see the full black screen before login, it’s probably caused by a malfunctioning device driver or hardware issue. If the blank screen happens after login, there’s probably something wrong with Windows, like a buggy Windows 10 update, or a problem with an installed application.
