Abstract
In a personal computer system which is equipped with a plasma display unit as a standard I/O device having a horizontal resolution of 640 dots and which can arbitrarily be connected to a CRT display unit having a horizontal resolution of 720 dots, a high-resolution display system includes a display timing data register suitable for the horizontal resolution of the CRT display unit. The display timing data stored in the display timing register is converted into display timing data having a horizontal resolution of 640 dots by a display timing converter. The converted timing data is stored in a clock management register, a clock mode register, and a horizontal panning register in a CRT controller. The high-resolution display system includes a circuit responsive to read access of the respective registers for transferring to a CPU the display timing data which has a horizontal resolution of 720 dots and which is stored in the display timing data register.
