Monitor Problems

For monitor problems, check the following:

1.If there is no display on the screen, check that the monitor’s power switch is on and that its power light is lit. If the power light is on but you still do not see anything on the screen, check the brightness and contrast controls.

2.If the power switch is on but the power light is not, turn off the monitor’s power, wait five seconds, and turn it back on. Wait to see if the screen displays any text.

3.If you still do not see anything on the screen, make sure you connected your monitor to the computer securely.

See “Connecting a Monitor” in Chapter 1 of the Setup Guide or your monitor manual for instructions.

4.If the monitor’s power light still does not come on, check the electrical outlet for power. Turn off your monitor and unplug it from the outlet. Then plug a lamp into the wall outlet and turn it on to see if the outlet supplies power.

5.If you installed a display adapter card, make sure your monitor and display adapter match. Also check to see if the card’s switches or jumpers are set properly. See “Using a Display Adapter Card” in Chapter 2 and your monitor and display adapter card manuals for instructions.
