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.
