Windows device driver information for COMPAQ QVision 150

The COMPAQ QVision 150 is a 15-inch CRT monitor produced and manufactured by Compaq. In general, CRT monitors make use of cathode ray tubes which are glass vacuum tubes into which an electron gun releases a stream of electrons led by an electrical field towards a screen enclosed in tiny phosphorescent elements. The electron gun is composed of a cathode, a negatively charged metallic electrode, and one or more anodes which are positively charged electrodes. The cathode releases the electrons fascinated by the anode. The anode functions as an accelerator and concentrator for the electrons, creating a flow of electrons intended for the screen. A magnetic field directs the electrons from left to right and from top to bottom. It is produced with two electrified X and Y plates also known as deflectors which transmit the flow horizontally and vertically.

Compaq is the manufacturer of the COMPAQ QVision 150. Typically, CRT monitors use cathode ray tubes. The screen is enclosed with an excellent layer of phosphorescent elements, better known as the phosphors which release light by excitation when electrons hits them, making a lit-up dot also known as pixel. Activating the magnetic field allows the electrons to go after a scan pattern, going from left to right and then down to the next row at the moment they reach the end. The human eye will not be able to see this scanning because of the persistence of vision. A black and white monitor can project various tones by varying the intensity of the flow. For color monitors, three electron beams which are coming from three different cathodes each hit a point with a precise color such as red, green, and blue. It is highly recommended you run a free registry scan for and COMPAQ QVision 150 errors before installing any driver updates.
