ViewSonic computer monitors are priced for affordability for all consumers, but are designed with filmmakers, graphic artists and gamers in mind. The widescreen LCD monitors have a dynamic contrast ratio and fast video response, resulting in seamless, undistorted images. ViewSonic's CRT monitors are highly rated on consumer websites and many models can be purchased for less than $200 (as of 2009). Like any electronics, ViewSonic monitors do have their share of technical issues, however.
Try your monitor with another computer if the picture won't come up at all. If the light on your ViewSonic monitor is on, then you know that the monitor is getting power. Make sure the problem isn't with the computer by testing the monitor with another computer.

Switch out the cable if there is still no picture with another computer. If the picture is still black, you can be sure the monitor is the issue. It will need to be returned or repaired.
Check the connections between the monitor and the computer if the picture doesn't come up every time you start your computer or if the picture on your screen occasionally goes out. Likely there's a loose connection somewhere. If your connections between the cable and the port on either the monitor or the computer seem loose, save yourself a lot of hassle by replacing the cable.
Use a CRT monitor's visual controls to adjust a blurry screen. ViewSonic recommends keeping the contrast at a higher level than the brightness for increased clarity. Another cause of screen blur is a damaged cable between the monitor and computer. If the cable is intact except for one bent pin, it might allow the picture to show but distort the image. Straighten the pin to its original position with a pair of pliers to avoid buying a new cable.
Never use an extension cable with your ViewSonic monitors. If you notice a shadow on the screen and you are using an extension cable instead of the one provided with your monitor, the extension cable is probably the culprit. While it may be nice to have a 10-foot cable between your computer and monitor, the cable's shielding impedes communication between the video card and the monitor. Use the cable provided and the problem should be fixed.
