If you have, or are planning to buy a Gateway FPD2185W monitor, you would have noticed that the pakage comes with a program called EZtune 1.0. This program is designed to work with the monitor it accompanies, allowing for advanced display configuration. While this all seems nice, the problems that come with this software should be noted.
Users who have installed the software have noted that programs frequently lock up and crash and that display abnormalities often occur. Several who have tried to work around EZtune's problems have succeeded, but found little reason for others to go through the trouble of installing the software in the first place.
There are complaints that EZtune also causes problems with FRAPS and interferes with internet connections. Games almost always seem to lockup or become corrupt to the point where the system had to restart or the game had to be re-installed in order for it to become accessible again. The problems that arose from installing EZtune seem to go away when one uninstalls the program.
THAT, and I can't find anything significant that you can do in EZtune that you cannot do using those buttons to the side of your monitor.
Here is a thread that eventually goes into further detail.
