If the video board was forced out of its slot and isn't secured with a screw, then the act of pluggingand unplugging video cables can force it out of its motherboard slot, if this happens, it can cause an electrical short to occur, which can destroy the board. Video Cable Issues 2:32-3:15 If the monitor and the video board both appear to be functioning correctly, then you may need to troubleshoot the video cable, common video cable issues include: a wrong DVI connector type, there are several different types of DVI video connectors, some of which are compatible with each other, while others are not. Verify that the connectors on both ends of the cable match up with the connectors on the video board and the monitor. Another issue is a damaged cable. Sometimes video cables are not routed in the proper locations and can be damaged by office chairs or foot traffic. Also, sometimes connectors are abused and pins get bent or broken off completely. Use a known good cable to test whether or not the suspect cable is working properly. VGA Mode errors 3:16-4:15 The next video problem we need to look at is that of the VGA mode being displayed. In this situation, the video display resolution is set to 640 x 480, at only 16 colors. In this configuration, the display geometry will likely appear distorted. You will probably also see oversized images and icons. This issue is almost always caused by a missing, buggy or incompatible video board driver. Whenever one of these issues occurs, Windows will default back to a very basic VGA video driver, which is compatible with most video boards and runs at a resolution of 640 x 480 with 16 colors. To resolve this issue, download and install the latest driver for the video board. Now occasionally, this issue may be seen when a user, knowingly or unknowingly, boots the system into Safe Mode. To ensure maximum hardware compatibility, Windows Safe Mode also uses a basic VGA video driver. This can be resolved by simply booting the system normally. Thermal Shutdown 4:16-4:42 Next, let's discuss thermal shutdowns. Some types of monitors generate a lot of heat. To prevent damage from overheating, many monitors include a thermal shutdown feature that will shut the monitor off if the temperature rises too high. To prevent this from happening, you need to ensureproper cooling by keeping the temperature in the room below 78 degrees Fahrenheit and by keeping the cooling vents on the monitor clear of obstructions, especially dust buildup. Color Calibration 4:43-5:18 You should also be familiar with color calibration issues. Most monitors can be calibrated to providethe most accurate color display. The steps for calibrating your monitor are to, one, set the video driver to use the monitor's native resolution. Two, set the color depth to 32 bits, this allows the full range of colors to be displayed.

    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.
