Explanation of the Characteristics of CRTs
When the monitor is not fully warmed up, the screen may look slightly colored, e.g.
reddish or bluish. This phenomenon is due to the unstableness of the electron gun
during its warm-up period. Please wait for about 30 minutes until the monitor
stabilizes in order to gain its proper color.
