In this interface, you can move monitors around to reflect their orientation and placement relative to each other. Dead or Stuck Pixels 8:08-8:40 You may also experience dead or stuck pixels in an LCD monitor, sometimes you can revive a dead or stuck pixel by applying pressure to the pixel with your finger as the monitor is powered on to redistribute the liquid within the LCD. Sometimes this works, but usually it doesn't. Another option is to use software to fix a dead or stuck pixel, the software sends special signals to the pixel to force it to function properly. As with the finger pressure trick, this option sometimes works, but frequently it doesn't. If this is the case, the monitor must be replaced. Burn-in 8:41-9:23 Another issue to be aware of is that of artifacts. Artifacts occur when elements of an image remain displayed on a screen after the image has changed to something else. This can happen when the same image is displayed on the screen for an extended period of time. Sometimes this is referred to as burn-in. This condition can be difficult to remedy. Usually the monitor will need to be replaced. However, you can try displaying high-intensity, high chroma screens of red, blue and green for a long period of time, upwards of a full day. Theoretically, displaying these high-intensity, high chroma screens should force the pixels to reset themselves, sometimes the method works, but frequently the monitor must be replaced. Summary 9:24-9:37 In this lesson, we talked about some of the generic video issues that you may need to troubleshoot,including: no display, VGA mode errors, thermal shutdown, color calibration, dim and flickering displays, distorted displays, dead or stuck pixels, and burn-in. When troubleshooting video, keep in mind that the problem might be with the video card, the monitor, or the software settings. A good place to start when troubleshooting video is to adjust the monitor settings (e.g., brightness, contrast, color balance, etc.). The following table lists several common video issues along with a possible solutions: Issue Solution System does not boot Computers require a functioning video card in order to boot. If the system does not boot and the monitor is blank, check the monitor's power and video connections. If the motherboard returns a POST error (either a code or a series of beeps), ensure the video card is seated properly and has the necessary power connections. o If the motherboard still returns a POST error, the video card is bad and should be replaced. Colors not correct Colors are not smooth Incorrect colors are often caused by low color depth settings.

A color palette is the current list of colors that can be shown on the screen. Color shift occurs when a new image must load a different palette than is currently used.

    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.
