the display may look three dimensional, but it is really just a 2D grid of pixels designed to appear that way.

Resolution

The resolution of any display is the number of pixels that can be depicted on screen as specified by the number of horizontal rows against the number of vertical columns. The default VGA resolution of many video cards is capable of displaying 640 rows of pixels by 480 columns. The typical resolution of current displays is set to higher values, such as 1024x768 (XGA), 1280x1024 (SXGA), or 1600x1200 (UXGA).

Saturation

Refers to the intensity of a specific hue (color). A highly saturated hue is vivid and intense, whereas a less saturated hue appears more grey. A completely unsaturated color is grey. In terms of the RGB color model, a fully saturated color exists when you have 100% brightness in one of the three channels (say, red) and 0% in the two others (green and blue). Conversely, a fully desaturated color is one where all of the color values are the same. Saturation can therefore be thought of as the relative difference between the values of the channels.

SCART

SCART is an acronym for “Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs”. SCART is an 21-pin connector used mainly in Europe for transferring analog audio and video signals between VCRs, DVD players, personal computers, and set-top boxes. It is sometimes referred to as Péritel or the Euroconnector.

Scissor Mode

A graphical load-balancing scheme where two graphics cards are used to render two halves of an image display. One graphics card renders the top half of the screen while the second graphics card renders the bottom half. This configuration offers a form of dynamic load balancing between the two cards as each only needs to render 3D object details on only half of the screen instead of the full screen at any one time. This type of graphical operation is only available in Radeon® CrossFire™ graphics cards running Microsoft® Direct 3D® and OpenGL® games or applications.

X1550 SERIES specifications

The ATI Technologies X1550 series, released in 2006, is a key component of the Radeon line aimed at delivering affordable yet capable graphics performance for entry-level desktop and mobile computing. This graphics card series is based on the RV530 architecture, which was designed to offer strong visual quality and a variety of features suited for mainstream users.

One of the standout characteristics of the X1550 series is its support for DirectX 9.0c and Shader Model 3.0. This enables the card to handle a range of graphics-intensive applications and games that utilize advanced shading techniques, providing a richer visual experience. Additionally, the inclusion of OpenGL support empowers software development for applications in CAD and 3D rendering, making it versatile for both gamers and professional users alike.

The X1550 series caters to various segments with different configurations, including the X1550 Pro, X1550, and X1550 XT. Users can expect these cards to come equipped with 128MB to 512MB of GDDR2 or GDDR3 memory, depending on the model. The memory bandwidth and capacity enhance the ability to render graphics smoothly even at higher resolutions, ensuring that users can enjoy a decent gaming experience on budget.

Another significant feature of the X1550 series is its implementation of ATI’s Avivo technology, which enhances video playback and enables high-quality video encoding. Avivo includes features such as UVD (Unified Video Decoder), allowing for efficient video playback and improved power management, which is especially beneficial for laptops.

The card also supports ATI's CrossFire multi-GPU technology, which allows users to link multiple graphics cards for enhanced performance in gaming and graphic rendering tasks. This scalability ensures that even entry-level graphics solutions can meet the demands of more modern applications when combined with another compatible card.

In terms of connectivity, the X1550 series comes with various output options, including DVI and VGA outputs, ensuring compatibility with a wide array of monitors. Some models also support HDMI, enabling users to connect to high-definition displays for an expanded viewing experience.

Overall, the ATI Technologies X1550 series stands out as a cost-effective solution for users seeking decent graphics performance without the financial investment associated with higher-end models. Its balance of features, from support for modern graphics APIs to video playback technologies, makes it a noteworthy option for entry-level gaming and general multimedia tasks.
