One of the most annoying things about monitors and TVs is that they leak black light. It usually shows up on the screen as cloudy spots of light. Some people also see bright black spots in the corners of their TV screens. LCD and LED displays usually use backlighting to light up their pixels, while OLED and MicroLED displays use front lighting. Because of this, both of these types of displays often have problems with backlight bleed.
Backlight bleed is when light leaks out of the corners or edges of an LCD. This is because of how these displays work. They use a light behind the panel that faces the display. Backlight bleeding means that some of the light from the back is getting through. There is no way to get rid of this completely, but it can be lessened in some situations. If your backlight bleeds too much, you may be able to RMA your display. Whether it’s a TV or a computer monitor, the image on your LED LCD is made with a backlight made of LED lights.
Backlight bleeding happens when some of that light doesn’t get completely blocked by the display’s bezels. Because of how display technology works, it’s normal for there to be a little backlight bleeding, which is fine since you probably won’t even notice it most of the time. But sometimes the backlight bleeding can be very distracting. If this happens, you may be able to return your display and get a new one or get your money back, depending on the RMA policy of the manufacturer. We mentioned below are the Steps to Fix Backlight Bleed on Monitor or TV.
Steps to Fix Backlight Bleed on Monitor or TV
- Clean the screen well with a microfiber cloth. This process is the same whether you are cleaning a Mac or Windows monitor or a large-screen TV. Ideally, distilled water and vinegar should be used.
- Check to see if your TV or monitor is still under warranty. If your laptop has this problem, check the laptop’s warranty. If it does, send in a repair request and the manufacturer should be able to fix the problem or send you a replacement display.
- If you are having trouble with an out-of-warranty monitor or TV, another option is to reduce the brightness. Adjust the brightness of the laptop or TV low enough so that the backlight blurring problem disappears. This is not an ideal solution, but it will allow you to continue using the display without problems.
- Another easy solution is to apply electrical tape to the edges of the display. This way, loose edges of the screen can be reattached, and the backlight will usually leak from the edges of the screen.
- Room lighting always affects TV viewing and PC gaming. The problem may appear worse when viewing the display in a dark room. This is not considered a “fix,” but you may not notice the problem if you try brighter room lighting.
- Use a screwdriver to loosen the screws on the back of the monitor or TV frame. You do not need to open the display as you would when repairing it. Simply loosen the screws and twist the screen slightly. If the screws on the frame are too tight, they may cause the backlight to bleed.
- If the backlight blurring problem is too severe to be addressed by any of the simple repair methods, you may need to purchase a new TV or a new desktop computer or laptop if there is no warranty.
What Is Backlight Bleeding?
LCD monitors use a light source called the backlight system, which is why this is a common problem. The whole panel is lit up, and it is up to the LCD to block out any light that isn’t needed to show a certain image. When you have backlight bleeding, the light is being blocked, which is why you see some bright spots that don’t look right and ruin the image. Even with the same model, backlight bleeding is not the same on all monitors.
Sometimes it’s not much, but sometimes it’s a lot. It might not bother you at all because you only see it in a few specific situations. You might also be sensitive to or tolerant of it, but it won’t cause any problems other than making it hard to watch or play. Even though figuring it out early will help you return the monitor while it’s still under warranty, there’s no need to worry. You don’t need to replace your monitor if you’ve been using it for a while and haven’t had many problems with it.
- The primary cause of backlight bleed is the light used to produce the image on the screen. It bleeds from the edges of the panel, producing a faint light that interferes with the primary image. Over time, as the display weakens and the panel becomes more separated, the backlight blurring can become more pronounced and more intense.
- If the screen is damaged, backlight blurring can increase quickly, especially as the panel separates. If you notice it after the TV or monitor has been impacted, dropped, or moved, it may be related.
- Although not the cause, backlight blurring can be more pronounced under certain environmental conditions. It is possible that you recently changed the location or lighting of your display, and this may have caused the backlight blurring to suddenly become more noticeable.
- Backlight blurring is not an uncommon problem, but it can be really disturbing. There are several fixes you can try to minimize its impact and improve the appearance of your display. However, over time, you may need to revisit these solutions from time to time, as backlight blurring is expected to increase on certain displays.
Final Words
Backlight bleeding is a common problem with modern displays that have a backlight that is turned on. This is also called “flashlighting” (backlight bleeding into the corners of the screen) and “clouding” (irregular patches of light remaining visible when the screen is supposed to be black) So, how do you handle this problem when it shows up? Whether you’re using a monitor or a smart TV screen, every change you make to the image quality can make the whole experience better.
Backlight bleeding is a small change that might not seem like much, but it can really change the way you see things. Even though all screens probably have some backlight bleeding, you can reduce it and make things look better on both big and small screens. We hope our article on “How to Fix Backlight Bleed on Monitor or TV” will surely help you to do so.
