What’s a Vector Monitor?

A vector monitor uses a laser to display images as outlines, avoiding pixelation. It can only display simple shapes and was limited to one color due to laser technology.

A vector monitor is a type of computer monitor, and sometimes a video game screen, that uses a laser to refresh the monitor’s image several times per second. While a vector monitor is not considered as advanced as modern liquid crystal display (LCD) monitors, this monitor is typically unaffected by pixelation. This is because only outlines are displayed, so all images are converted to vectors. It was difficult to make multi-color lasers when this monitor was first used, so this monitor normally only displayed one color.

In early monitors, the image on the screen was the result of a laser constantly beaming an image onto the glass of the screen. With a vector monitor, this laser sweeps across the screen multiple times per second to ensure the image doesn’t disappear. The laser worked constantly because if it missed a transmission step, the screen image would start to fade and fade. The laser moved so quickly that most people wouldn’t see any fading before the image was reloaded.

Modern computers, despite having better resolutions and more vivid colors, can suffer from pixelation if the image on the screen is a low resolution image. While a vector monitor didn’t have many of the capabilities of more modern monitors, one advantage was that it wasn’t affected by this problem. Any images appearing on the screen would be very sharp, even if the images were commonly simple shapes such as circles or triangles.

A vector monitor was unaffected by pixelation, because the laser converted all images into vectors. The points of a vector are saved instead of its pixels, so the monitor would have more time to display a vector image without blurring or other display problems. At the same time, this monitor could only display and remember points, so the display capabilities were weaker than most modern monitors, because most carriers can’t be advanced shapes.

Later versions of the vector monitor were capable of displaying two or more colors simultaneously, but most of these monitors could only display one color. This is due to the state of laser technology when this monitor was popular. It was initially difficult to make a laser with more than one color that would not cancel during transmission. Even when more than one color was possible, this was not due to the laser, but to the use of layers of phosphor, each showing a different color, in the monitor.
