The Samsung SyncMaster is a computer monitor that boasts a large amount of digital inputs. This monitor can connect to almost anything, but you won't be able to enjoy its versatility if you are having problems with it. Fortunately, there are some simple troubleshooting steps you can take to help solve simple issues that may be causing your SyncMaster monitor to malfunction. These steps are fairly straightforward and do not require any technical knowledge.

Double-check all cords. The SyncMaster monitor has many inputs, and if a cord is placed in the wrong port or has become loose, the display will appear corrupted or blank.

Adjust the input resolution on the device connected to the SyncMaster. If an error pops up saying "Video Mode not Supported," your SyncMaster is not able to handle the current resolution level. See your input device's owner's manual for instructions on how to lower the input resolution.

Press the "OSD" button for 5 seconds to make sure the SyncMaster is unlocked. If the monitor has been idle too long or the lock function has been enabled, the screen will not show anything until the screen is unlocked.

Adjust color and video settings. If the graphics on the screen appear washed-out or pixelated, adjust the color and video settings on the computer. If you are using Windows, go to "Control Panel," click "Display" and then "Settings" (if you are using a Mac, go to "System Preferences" and click "Display"). Then adjust the color and video settings to the optimum level.
