How to Fix Computer Monitor Display Problems?

Are you having any display issues on your computer monitor? No matter if it is a CRT monitor, LCD or LED.Follow these instructions on How to fix monitor display?

Problem 1: There is no display on the monitor

Solution: This might sound silly. Make sure the computer and monitor are plugged into a power source and it is switched on. If there is no indication of power which can be confirmed by checking if the LED light is turned on or presence of sound coming from the computer fan, check if the power cords from the PC and monitor are properly and firmly connected. If you have multiple monitors for dual screen display, toggle between the chords to see if there is compatibility issue between the monitors. Still don’t see anything? Check to ensure that the video cable is connected to video output on your PC and the input on your monitor. Gently wiggle the cord to see if the plugs are secure. If you still have trouble, try a spare (or borrowed) monitor on the computer. Connect the spare monitor to see if the computer is capable of displaying video. If the second monitor works, your original monitor may be faulty. On the flip side, if it doesn’t work, the PC may be the cause of your problem.

Problem 2: Video light is too dark or bright

Solution: Some monitors feature Brightness or Contrast buttons that could be easily (mis)adjusted while moving or cleaning the monitor. Fortunately, most monitors feature a Default Settings or Factory Reset function you can use to restore the display settings, but many monitors feature an OSD (onscreen display) that will let you adjust the visual properties through a menu system with sliders for each adjustable option. If you’ve cranked the Brightness and Contrast controls and the screen still seems dark, you may need to take the monitor in for repairs. LCD backlights can sometimes fade or malfunction, which would results in the dim display. (Get an estimate; it may be smarter to simply replace the display, depending on the cost of the repair.)

Problem 3: Images on the screen does not match the screen size

Solution: It’s sometimes possible to choose a resolution that’s not compatible with your monitor. For instance, if you select the 1600 x 1200 resolution and the monitor can only handle a resolution of 1280 x 1024, the display may only show part of your Desktop—requiring you to move your mouse to view other portions. Check your monitor’s documentation to see the maximum resolution you can use. To change resolution in Windows 7 and Windows 8, right-click an open area of your Desktop and select Screen Resolution. From the drop-down list, select a resolution that matches the native resolution of your monitor. Click Accept; you’ll have 15 seconds to approve the change by clicking the Keep Changes button.

Problem 4: Flickering of monitor and video dropping out occasionally

Solution: Generally, flicker and dropouts are the result of a bad (or poorly connected) video cable running between your PC and monitor. Try unplugging and firmly reattaching the cable to the video input and outputs. Flicker can also result from a change to the monitor’s refresh rate, which is the number of times per second the monitor redraws the screen. (The accidental change most often occurs when you update video drivers.) To reduce flicker on your monitor, try to increase the Refresh Rate in Windows. In Win7 and Win8, right-click an open area of your Desktop, select Screen Resolution, and click Advanced Settings. Next, select the Monitor tab and select a different rate from the Screen Refresh Rate drop-down window. Click Apply and try out the new refresh rate
