Loose or improperly connected cables are likely sources of problems for your com-
puter, external monitor, or other peripherals (such as a printer, external keyboard, or
mouse). A quick check of all cable connections can easily solve these problems. If the
connector has two small screws, make sure the screws are tight. In addition, check
for damaged or frayed cables and for bent pins on connectors.
Be sure the following items are properly connected or installed, as shown in Figures
