1. A picture display device for displaying a video signal supplied from a data process device, comprising:
- input means for inputting a plurality of video signals that are outputted by a plurality of data process devices;
communication means for bi-directionally communicating with each of the plurality of data process devices to receive associated synchronous frequency information for each of the plurality of video signals;
video process means for combining the inputted plurality of video signals into a combined video signal for display on one screen according to associated picture size information for each of the plurality of video signals, the picture size information associated with a given one of the plurality of video signals being based on the received synchronous frequency information associated with that video signal;
display means for displaying the combined video signal that is outputted from said video signal process means;
input device connection means for connecting to an input device and for receiving, from the input device, a first control signal based on a user input operation;
transmission means for generating a second control signal for controlling the plurality of data process devices, the second control signal being based on the first control signal outputted from said input device connection means, and for causing said communication means to transmit the first control signal and the second control signal to the plurality of data process devices; and
communication control means for controlling said communication means to communicate with each of the plurality of data process devices.

Abstract
Video signals from a plurality of personal computers are written to a memory that stores video signals for a plurality of display screens through respective buffers. The video signals may be read from the respective buffers and displayed simultaneously on a single monitor. By selecting the video displayed in a portion of the monitor, the personal computer sending those video signals to the monitor may be selected for active operation. In this manner, a single set of input devices may be used to control a plurality of personal computers.
