A monitor support comprises a monitor supporting part 21 which contains speakers 24 and supports the monitor 26. The monitor supporting part rests on a base 20 to which it is coupled on the base to be rotatable, a side of the monitor supporting part being formed with two speaker fixing portions (23); a connector 22 for connecting the base and the monitor supporting part so that the monitor supporting part can be rotated; and a shield (25) for sealing the upper portion of the monitor. Therefore, the howling phenomenon in the monitor is prevented since the sound pressure generated by the speakers is prevented from being transferred to the cathode-ray tube of monitor.
