Three, let the monitor reach operating temperature. Four, print out an image on a high-quality, properly calibrated color printer. And five, adjust the monitor contrast, brightness and colors to match the printed image, as much as possible. Dim Image 5:19-5:39 Another common issue is that of a dim image displayed on an LCD monitor. A dim image on an LCD monitor is usually caused by one of two things: a misconfigured brightness setting or a malfunctioning backlight. If the problem is caused by a misconfigured brightness setting, then you can use the monitor controlsto adjust it to the correct level.

Flickering Image 5:40-6:42 An LCD panel produces little illumination, in order to see an LCD screen, it has to be illuminated by a backlight. The backlight uses a small fluorescent light, or CFL, that runs on AC power, as such, they require an inverter to convert DC power from the monitor power supply to AC power. Now if an LCD display is dim and the brightness setting is correctly configured, it could be caused by a burnt out CFLor a malfunctioning inverter. If parts are available, these components are usually relatively easy to replace, however, not all displaymanufacturers make replacement parts available for their monitors, if this is the case, then the monitor will have to be replaced. You also observe a flickering screen on an LCD monitor. Once again, this is usually caused by the backlight or its inverter, the backlight itself may be burnt out and in need of replacement, it could also be caused by a malfunctioning inverter that isn't providing enough power to run the backlight, causing it to flicker. Distorted Display 6:43-7:22 Another issue you may see when working on LCD, LED and plasma monitors is that of distorted display geometry. This usually happens when the display resolution configured on the video board isn't supported by the monitor. When configuring the display resolution, you need to set the resolution on the video board to the native resolution of the monitor. LCD, LED and plasma monitors use a fixed raster and can't change the resolution to match the signalthat's being sent to it from the video board. If there's a mismatch, then the monitor will useinterpolation to scale the image displayed on the screen, which results in a significant loss in image quality. Multiple Monitor Misalignment 7:23-8:07 You may also need to troubleshoot issues with the alignment of multiple monitors, the alignment should reflect the physical placement of the monitors in relation to each other, if done correctly, the mouse cursor will track properly when moved between monitors. If not aligned correctly, the mouse will not track properly. In fact, the user may not be able to move the mouse between the monitors at all. To adjust the monitor orientation and alignment, you customize the display settings. In older versions of Windows, these settings are found in Control Panel under Appearance and Personalization. In newer versions of Windows, they are found in the Settings app under System.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
