Question:

What could be the cause of a persistent black bar at the bottom of my screen that disappears only when I play Minecraft?

I have noticed a black bar that has been gradually expanding across the bottom of my screen for almost a year. It is now about two inches high and covers part of the taskbar. I was informed that it might be due to water damage and dead pixels, but I find it strange that it vanishes completely when I launch Minecraft, and reappears when I exit the game. Do you have any ideas on what could be causing this problem and how to fix it?

Answer:

A black bar at the bottom of your screen that does not go away even after restarting your computer or updating your drivers can be very annoying and frustrating. It can also interfere with your productivity and enjoyment of your device. You might wonder what is causing this problem and how to fix it.

There are several possible causes of a black bar on your screen, such as:

• Water damage: If you have spilled liquid on your screen or exposed it to moisture, it can damage the pixels and cause them to malfunction. This can result in black or colored spots or lines on your screen that do not respond to any input. Water damage can also affect other components of your device, such as the motherboard, the battery, or the keyboard.
• Dead pixels: Pixels are the tiny dots that make up the images on your screen. Each pixel has three subpixels: red, green, and blue. When one or more of these subpixels stop working, the pixel becomes dead and appears as a black spot on your screen. Dead pixels can be caused by manufacturing defects, physical damage, or aging of the screen. They can also spread over time and form larger areas of blackness on your screen.
• Screen burn-in: Screen burn-in is a phenomenon where a static image or a part of an image remains on your screen even after you change the display or turn off the device. This can happen when you leave your screen on for a long time without changing the content, such as a screensaver, a menu, or a logo. Screen burn-in can affect LCD, LED, OLED, and plasma screens. It can cause permanent damage to your screen and reduce its quality and lifespan.

However, none of these causes can explain why the black bar on your screen disappears only when you play Minecraft. This suggests that the problem is not with your screen itself, but with the software or settings of your device. Here are some possible explanations for this behavior:

• Resolution mismatch: Resolution is the number of pixels that your screen can display horizontally and vertically. Different applications and games can have different resolutions, depending on their design and optimization. If the resolution of your game is higher than the resolution of your screen, it can cause some parts of the game to be cut off or distorted on your screen. This can also happen if you have changed the resolution settings of your device or your game manually. To fix this, you need to adjust the resolution settings of your device or your game to match each other and your screen. You can do this by going to the display settings of your device or the video settings of your game and choosing the appropriate resolution option.
• Fullscreen mode: Fullscreen mode is a display option that allows you to play a game or watch a video using the entire screen of your device, without any borders, menus, or toolbars. This can enhance your immersion and performance of the game or video. However, fullscreen mode can also cause some problems, such as compatibility issues, crashes, or glitches. One of these glitches can be a black bar on your screen that covers part of the game or video. This can happen if the aspect ratio of your game or video is different from the aspect ratio of your screen. Aspect ratio is the ratio of the width to the height of your screen. For example, a common aspect ratio for screens is 16:9, which means that the width is 16 units and the height is 9 units. If the aspect ratio of your game or video is different, such as 4:3 or 21:9, it can cause some parts of the game or video to be stretched or compressed on your screen, or leave some empty spaces on the sides or the bottom of your screen. To fix this, you need to change the display option of your game or video from fullscreen mode to windowed mode or borderless windowed mode. You can do this by going to the video settings of your game or the playback settings of your video and choosing the appropriate display option.
• Graphics card issue: Graphics card is a hardware component of your device that processes and renders the images and videos on your screen. It is essential for running high-quality games and videos on your device. However, graphics card can also malfunction or become outdated, which can affect the performance and quality of your games and videos. One of the symptoms of a graphics card issue can be a black bar on your screen that appears or disappears when you run certain games or videos. This can happen if your graphics card is not compatible with your game or video, or if your graphics card driver is corrupted or outdated. To fix this, you need to update or reinstall your graphics card driver, or replace your graphics card with a newer or better one. You can do this by going to the device manager of your device or the website of your graphics card manufacturer and downloading and installing the latest driver for your graphics card model.
