Abstract: A monitor with a screen adjustable in highness and inclination provides a H-shaped adjusting member with a first end, a second end, a third end and a fourth end to connect with shafts attached to support arms extending from the base in association with an actuation part to allow the adjusting member capable of rotating on the base. Further, the adjusting member is rotationally connected to a main monitor member with another shaft and another actuation part. Besides, two four-bar linkages each provide a fixing end to connect with two of the shafts on the support arms and a movable end to connect with the other two of the shafts on the support arms for obtaining strong structure of the monitor and adjusting highness and inclination of the screen conveniently.
