Environmental requirements

Flame retardants

Flame retardants are present in printed circuit boards, cables, wires, casings and housings. Their purpose is to prevent, or at least to delay the spread of fire. Up to 30% of the plastic in a computer casing can consist of flame retardant substances. Most flame retardants contain bromine or chloride, and those flame retardants are chemically related to another group of environmental toxins, PCBs. Both the flame retardants containing bromine or chloride and the PCBs are suspected of giving rise to severe health effects, including reproductive damage in fish-eating birds and mammals, due to the bio-accumulative* processes. Flame retardants have been found in human blood and researchers fear that disturbances in foetus development may occur.

The relevant TCO'99 demand requires that plastic components weighing more than 25 grams must not contain flame retardants with organically bound bromine or chlorine. Flame retardants are allowed in the printed circuit boards since no substitutes are available.

Cadmium**

Cadmium is present in rechargeable batteries and in the colour-generating layers of certain computer displays. Cadmium damages the nervous system and is toxic in high doses. The relevant TCO'99 requirement states that batteries, the colour- generating layers of display screens and the electrical or electronics components must not contain any cadmium.

Mercury**

Mercury is sometimes found in batteries, relays and switches. It damages the nervous system and is toxic in high doses. The relevant TCO'99 requirement states that batteries may not contain any mercury. It also demands that mercury is not present in any of the electrical or electronics components associated with the labelled unit. There is however one exception. Mercury is, for the time being, permitted in the back light system of flat panel monitors as today there is no commercially available alternative. TCO aims on removing this exception when a Mercury free alternative is available.

CFCs (freons)

The relevant TCO'99 requirement states that neither CFCs nor HCFCs may be used during the manufacture and assembly of the product. CFCs (freons) are sometimes used for washing printed circuit boards. CFCs break down ozone and thereby damage the ozone layer in the stratosphere, causing increased reception on earth of ultraviolet light with e.g. increased risks of skin cancer (malignant melanoma) as a consequence.

Lead**

Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the nervous system and in higher doses, causes lead poisoning. The relevant TCO'99 requirement permits the inclusion of lead since no replacement has yet been developed.

*Bio-accumulative is defined as substances which accumulate within living organisms.

**Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.

757DFX specifications

The Samsung 757DFX is a high-performance monitor that captivates users with its vivid visuals and advanced technology. Launched with a focus on delivering exceptional color accuracy, this model stands out in the crowded market of computer displays.

One of the main features of the Samsung 757DFX is its 17-inch CRT display, which provides a resolution of 1280 x 1024 pixels. This high resolution allows for sharp images and crisp text, making it an excellent choice for a variety of applications, from graphic design to everyday office work. The monitor’s dot pitch of 0.24 mm contributes to its clarity, ensuring that users can enjoy detailed visuals without blurriness.

Another key characteristic of the 757DFX is its large viewing angle of 160 degrees horizontally and vertically. This feature allows multiple viewers to enjoy the screen from various positions without experiencing color distortion or a drop in quality. This makes it particularly useful in collaborative environments or for multimedia presentations.

The Samsung 757DFX employs a technology known as "MagicBright," which is designed to automatically adjust brightness settings based on the type of content being displayed. This not only enhances the viewing experience but also helps to reduce eye strain during long hours of use. The monitor supports various color modes, including Standard, Internet, and Text, giving users the flexibility to customize their preferences based on their activities.

In terms of design, the 757DFX has a sleek and modern look, with a compact footprint that fits comfortably on desks without occupying too much space. The monitor features intuitive on-screen controls for easy navigation through settings, allowing users to make adjustments effortlessly.

Furthermore, the Samsung 757DFX is equipped with advanced anti-glare technology, which minimizes reflections and prevents distractions from ambient light. This feature ensures that users can work effectively in brightly lit environments without the hindrance of glare.

To summarize, the Samsung 757DFX monitor is a blend of performance, functionality, and user-friendly features. Its excellent resolution, wide viewing angles, and proactive technologies make it a reliable choice for both professional and personal use. Whether for gaming, graphic design, or general computing, the 757DFX provides an impressive visual experience that meets the demands of modern users.
