A hinge is compact and can hold a monitor securely in an optimum angle even if it is long-term used. The hinge has a body, a pivoting member rotatably mounted on the body and has a pintle, a first positioning element and a second positioning element mounted on the pintle. The first positioning element has a groove formed inclinedly in a front surface at an angle. The second positioning element is simultaneously rotated with the pintle and has a rear surface corresponding to the front surface of the first positioning element and a rib formed diametrically on the rear surface. The rib corresponds to and selectively engages with the groove in the first positioning element with resilience of a resilient element to retain the pivoting member at a determined angle.
