Vertical dot pitch

See Dot pitch.

Vertical scanning frequency

Expressed in Hz, this is the number of fields written to the screen every second in interlaced mode. In non-interlaced mode vertical scanning frequency is the number of frames (complete pictures) written to the screen every second (also known as refresh rate).

Vertical sync pulses

A train of square shaped waveforms that define the start of a new frame.

VESA

Video Electronic Standards Association, a consortium of manufacturers formed to establish and maintain industry-wide standards for video cards and monitors. VESA was instrumental in the introduction of the Super VGA and Extended VGA video graphics standards (see Video graphics adapters) with a refresh rate of 70 Hz, minimizing flicker and helping to reduce operator eyes fatigue and stress.

Video dot rate

See Dot rate.

Video graphics adapters

A card equipped with a character or graphic generator and video memory, which maps to the screen. A microprocessor scans video memory and translates bit information from the computer into displayable video signals for the monitor. These cards comply with various standards that determine the nature and quality of the display.

VGA (Video Graphics Array), introduced in 1987, was the first analog card. It offered still higher resolution than EGA: 640 X 480 pixels for graphics and 720 x 400 pixels for text, and a color palette of 256 colors. VGA could also emulate EGA and CGA.

Super VGA, devised by VESA in 1989, offers a resolution of 800 x 600 pixels.

Extended VGA, introduced by VESA in 1991, offers a top resolution of 1024 x 768 pixels (non-interlaced) and a refresh rate slightly higher than IBM's XGA 8514A.

One of the standout features of the Philips 109P is its CRT (cathode ray tube) display technology, which was widely used before the advent of LCD and LED screens. This monitor provides vibrant colors and deep contrast ratios, delivering a visually appealing experience. The CRT technology allows for excellent color reproduction and smooth gradients, which is particularly beneficial for graphic designers and photographers who require accurate color representation.

The Philips 109P features a 19-inch screen size, which strikes a balance between desktop space usage and viewing comfort. The display has a resolution of 1280 x 1024 pixels, allowing users to enjoy a decent amount of detail for various applications, from office work to multimedia consumption. Additionally, the monitor supports a refresh rate of up to 85 Hz, which minimizes flicker and enhances stability during prolonged use.

Another characteristic of the Philips 109P is its versatile adjustability. The monitor supports tilt adjustments, enabling users to customize the viewing angle according to their preferences. This ergonomic design is complemented by its anti-glare screen coating, which reduces reflections and improves visibility in brightly lit environments.

Connectivity is another strong suit of the Philips 109P. It typically includes a range of input options, most notably the VGA connector, allowing it to connect to a variety of computers and devices. This makes it a compatible choice for users with older PCs or those looking to utilize it in specific industrial settings.

Durability is a hallmark of the Philips brand, and the 109P is no exception. Built to withstand the rigors of daily use, it features a sturdy chassis that can endure the wear and tear common in an office environment. This longevity makes it an appealing investment for businesses and individuals looking for a dependable monitor.

In conclusion, the Philips 109P combines classic CRT technology with essential features that cater to a wide range of users. With its solid performance, vibrant display, and practical design, the Philips 109P remains a noteworthy model for those who appreciate reliability in their computing experience.
