As one of the most popular manufacturers of monitors, ViewSonic is known for its quality, well-built monitors. As with all electronics, however, you may run into some problems with a monitor, whether it's with the initial setup or troubleshooting after years of use. If you do run into a problem, there are some tips you can use to get your monitor working correctly.
Check On-Screen Display
If your problem is related to the image that appears on your screen, it may be related to the monitor's settings. This would include problems with the colors being off, the image extending past the edges of the screen or any number of other display issues. Many of these problems can be solved through adjusting the display settings of your monitor.
Using the small buttons located on your monitor (usually beneath the screen on most ViewSonic monitors), you can pull up the On-screen Display or OSD.
ViewSonic CRT monitors have a variety of adjustable settings, including Contrast, Brightness, H. Size/Position, V. Size/Position, Zoom, ViewMatch, Pincushion, Tilt, Moire Reduction, Degauss, OSD position and Memory Recall.
If the image on your monitor appears too blue or too red, you will want to edit color temperature with the "ViewMatch" settings, which has four preset values (9300, 6500, 5000, User). If the size of the displayed image does not stretch to the edges of the monitor, you will want to modify the "H. Size' and V. Size" settings.
ViewSonic LCD monitors change the name of the color temperature setting to "Color Adjust," and image size adjustments must be made within the "Manual Image Adjust" menu on the OSD. Different lighting conditions can also alter the appearance of colors, which may require adjustments to your color temperature settings.
Both ViewSonic LCD monitors and CRT monitors offer a "Memory Recall" function within the on-screen display menu that allows you to revert to the previous settings after making changes.
Check Drivers and Cables
If you are unable to get an image to show up on your monitor, it is important to check that the necessary cables are attached correctly and that the proper drivers are installed. Drivers are available directly through the ViewSonic website.
Older ViewSonic CRT monitors use a VGA cable to connect to your PC. If you own an LCD monitor, some use a VGA input while others take advantage of the newer DVI interface to provide a connection to PCs (some LCDs offer both types). When connecting your monitor for the first time, you should make sure you have the right type of cable for both your monitor and computer. In some cases an adapter may be necessary to convert the DVI signal from your monitor to work in a VGA input on your PC.
You should make sure that the VGA or DVI cable is tightly attached to the back of your monitor and to the back of your PC. It is best to use the small thumb screws on the ends of the connectors to keep everything tightened in place, which will prevent the cable from getting loose.
All ViewSonic monitors also use a power cable to plug into a power source. If the power light does not comes on, check to make sure that the power cable is inserted fully into the back of the monitor and that it is plugged into a working wall outlet or a reliable surge protector.
Check ViewSonic User Guide
Depending on the model of your monitor, there may be extra features that require special troubleshooting tips, or there may even be alternate ways of troubleshooting basic problems. For this reason, it is important to keep your user manual. If you do not have the user guide for your monitor available, ViewSonic offers them for download through the support section of its website.
If you have come across an issue with your monitor that cannot be corrected through the basic settings, you should consult the user manual to determine troubleshooting solutions for your specific ViewSonic monitor.
Some monitor problems may be bigger than a troubleshooting session can fix, so if your user manual still does not solve the problem, it may be necessary to contact ViewSonic's customer support team via phone to discuss what is wrong with your monitor.
If you own a newer monitor, problems requiring repair may be covered under ViewSonic's warranty. Most ViewSonic monitors carry a three-year limited warranty, although this may not apply to refurbished items. Terms of the warranty of any type of ViewSonic monitor can be found in the Support section.
