![]() (This design has been largely superseded by LED backlighting, but there are still plenty of CFL-equipped monitors in use.) Buzzing can occur due to problems in power regulation to one or more bulbs. The most common problem that can cause a buzz or whine noise in a monitor is an issue with the backlight, usually with the compact florescent tubes used for lighting in older models. You could try to replace the LCD panel itself, but since the replacement part will be almost as expensive as a new monitor anyway, you might as well start shopping. There’s nothing you can do here: even if your monitor is within its warranty period, it almost certainly won’t cover physical damage. If your monitor has a visible crack, a large discolored area, or a black/multicolored spot that doesn’t align with the pixel grid, it’s been subjected to physical trauma and the LCD panel is damaged. You can try out some of these solutions as outlined in our guide to stuck pixels, but be warned, in my personal experience, it’s exceedingly rare to find a lasting solution to a stuck pixel. There are various techniques for this, ranging from physically “massaging” the screen panel itself to running programs that rapidly cycle a portion of the screen through the color spectrum. Depending on exactly how the problem is manifesting, it might be possible to get the pixel back into working order. RELATED: How to Fix a Stuck Pixel on an LCD MonitorĪ stuck pixel may be a different matter. You can also look into a warranty replacement, though many monitor manufacturers won’t replace a screen until multiple pixels have gone out. Luckily one or two dead pixels usually doesn’t mean you have to throw the whole monitor away it’s certainly possible to work around it or ignore it. There isn’t much you can do for a dead pixel-it’s a physical malfunction of the screen panel. “Stuck” pixels are similar, but instead of showing black they’re stuck on a single color that doesn’t match the computer screen’s image, typically either red, green, or blue. Dead or Stuck PixelsĪ “dead” pixel is a single dot on your LCD screen that doesn’t illuminate, showing up as one or more black squares. Try your monitor on another computer or laptop to see if the problem persists if it does, you’re probably looking at a replacement, since the error is almost certainly in the LCD panel (the most expensive component of the monitor). Go into your operating system’s display settings (right-click desktop and head to Display settings > Display adapter properties > Monitor in Windows 10) to make sure the right hertz setting is applied-you may need to update your video drivers as well.īlack or single-colored lines on LCD screens are caused by a lot of different issues, but if the standard fixes outlined in the flickering section above don’t fix them (check your video and power cables for problems, install new drivers), it’s probably a physical defect in the screen itself. Most LCD monitors use either 59 or 60 hertz, though 75Hz, 120Hz, and 144Hz are also found on premium monitors. The refresh rate is the number of times the computer sends an image to the monitor per second, expressed in hertz. The same thing goes for the power cable: make sure it’s secure at both ends, and if the problem persists, replace it if possible.Īn incorrect refresh rate setting can also cause flickering. So first, tighten down the cable on both the monitor and the computer end (making sure to completely tighten any retention screws, if your cable has them) or simply replace the cable. It might be something as simple as a loose or faulty video cable.
