Following are some of the more common monitor troubles encountered:
My monitor screen is blank.
- Make sure the monitor is turned on – you should see a power light (usually green or orange) on the front of the monitor. If there’s no light, try pressing the power button.
- If you stepped away from your computer for a few minutes, and your screen was blank when you came back, the monitor may have gone to “sleep” (a power-saving mode when the monitor is not in use). Try moving or clicking your mouse, or pressing any key (“where’s the any key?”) such as the space bar.
- Make sure that the monitor cord to/from the monitor to the computer tower is firmly connected on both ends.
The image on my screen is “wonky” – distored or skewed.
- If the cable to/from the monitor to the computer tower is loose or defective, you may get a distorted image. Disconnect the cable at the computer tower, and make sure none of the “pins” in the end of the cable are bent, broken, or missing.
- If the refresh rate is not properly set, the image may look “wavy”, or have lines going across the monitor (either slow or quickly), or may flicker.
- A distorted image may also be caused by magnetic or other types of interference. Make sure there are no speakers, fans, or other magnetic devices close to the monitor
My monitor shows a “no signal input” message on the screen.
- Make sure that the cable to/from the monitor to the computer tower is firmly connected on both ends.
- Make sure that a cable any where else is not loose. Disconnect all cables that can be disconnected in the back of the monitor (usually the data cable cannot be disconnected).
- Disconnect the data cable connected to the back of the computer, and reconnect it. When connecting the cable in the back of the computer, make sure the cable connection is tight. Most computers will have screws on either side of the cable that must be screwed into the computer tower to hold the connector firmly in place.
There are black borders on my screen.
- First, check if the resolution has been changed. If it was recently changed, the monitor may not auto-adjust to the correct size. You can change the resolution back to the original setting, or you can manually readjust the monitor. Usually a black border can be fixed by manually adjusting the horizontal or vertical width. Because each monitor is different, please consult your monitor user manual on how to do this.
