Due to the possibility of damaging your monitor, the recently released Quake 4 v1.1 patch has been officially recalled. According to id Software's statements the wide-screen functionality in this patch may harm a user's monitor. It is recommended to down-grade the Quake 4 installation or to NOT enable/disable this display setting. A new patch is anticipated to be released soon. An updated SDK for Quake 4, however, is available at this time.
