Abstract: A monitor adjusting apparatus include a monitor (10), a base (20) and an adjusting device (30). The adjusting device includes a first pivot assembly (40) connected with the monitor, a second pivot assembly (50) connected with the base, and a connecting assembly (70) mounted between the first pivot assembly and the second pivot assembly. The first pivot assembly generates a friction moment. The monitor generates a first gravity moment opposite to the friction moment. The second pivot assembly generates a twist moment. The monitor and the connecting assembly generate a second gravity moment opposite to the twist moment. The monitor stays at any obliquity under a balance of the friction moment and the first gravity moment, and stays at any height under a balance of the twist moment and the second gravity moment.
