An automatic switching device for the power source input range of a personal computer monitor is installed within the switchmode power source circuit of the monitor and includes a comparator and a relay arranged so that, irrespective of whether the power source is at a 110V or 220V voltage level, the rectifying circuit of the switchmode power source circuit is automatically switched to a voltage doubler circuit or a bridge rectifier circuit as appropriate for reducing power losses and saving energy.

Automatic switching device for the power source input range of a monitor used in a personal computer

A computer monitor power supply system includes a comparator, a relay, and an inductor connected in series between the AC input and a flyback transformer circuit. The inductor includes two windings which are automatically switched between a parallel connection and a series connection upon switching between a 110 V and 220 V power input so as to reduce the amount of low frequency harmonics.

Multi-sync monitor power supply system with harmonic eliminating means

A help service function control device is added to a multi-sync(or multi-modc)monitor of a personal computer. The control device uses a micro controller and an on-screen display to control a video display to show the contents of 'Help Service'. The help service contains Install. Adjustment and Specification instructions for instructing the user to install and adjust the monitor and to understand the specifications of the monitor. The micro controller picks up a serial signal from the on-screen display, permitting the fetched signal to be amplified by a video pre-amplifier and then displayed through the video display so as to help the user eliminate troubles.
