Troubleshooting video problems involves determining which of the following is the source of the problem: the monitor, the monitor interface cable, the video memory, or the video logic of the computer. You can also have a high-resolution video expansion card installed, which overrides the video logic of the computer. The following procedure troubleshoots problems with the video memory and video logic only. Before you begin, perform the procedure found in "Troubleshooting the Monitor" in Chapter 6 to determine whether or not the monitor is the source of the problem. If you have a high-resolution video expansion card, first complete the steps in "Troubleshooting Expansion Cards" found earlier in this chapter to verify that the card is configured and installed correctly. 7-14 Dell PowerEdge 2300 Systems Installation and Troubleshooting Guide
