Trapezoid distortion

See Geometrical distortion.

TTL signal

A TTL (Transistor-transistor-logic) signal is a digital signal level for controlling the screen colors. With TTL driving, the red, green and blue signals can only be switched on or off or provided with an intensity signal. A TTL-driven monitor can thus display a maximum of 64 colors. Video standards such as MDA, CGA and EGA are based on TTL level.

U

USB or Universal Serial Bus

A smart plug for PC peripherals. USB automatically determines resources (like driver software and bus bandwidth) required by peripherals. USB makes necessary resources available without user intervention.

●USB eliminates "case angst" -- the fear of removing the computer case to install add-on peripherals. And USB also eliminates adjustment of complicated IRQ settings when installing new peripherals.

●USB does away with "port gridlock." Without USB, PCs are normally limited to one printer, two Com port devices (usually a mouse and modem), one Enhanced Parallel Port add-on (scanner or video camera, for example) and a joystick. More and more peripherals for multimedia computers arrive on the market every day. With USB, up to 127 devices can run simultaneously on a computer.

●USB permits "hot plug-in." There's no need to shut down, plug in, reboot and run set-up to install peripherals. And no need to go through the reverse process to unplug a device.

In short, USB transforms today's "Plug-and-Pray" into true Plug-and-Play!

Hub

A Universal Serial Bus device that provides additional connections to the Universal Serial Bus.

Hubs are a key element in the plug-and-play architecture of USB. The Figure shows a typical hub. Hubs serve to simplify USB connectivity from the user's perspective and provide robustness at low cost and complexity.

Hubs are wiring concentrators and enable the multiple attachment characteristics of USB. Attachment points are referred to as ports. Each hub converts a single attachment point into multiple attachment points. The architecture supports concatenation of multiple hubs.

The upstream port of a hub connects the hub towards the host. Each of the other downstream ports of a hub allows connection to another hub or function. Hubs can detect, attach and detach at each downstream port and enable the distribution of power to downstream devices. Each downstream port can be individually enabled and configured at either full or low speed. The hub isolates low speed ports from full speed

109S20, 105B20, 107S20, 107S21 specifications

Philips has long been a leader in the display technology industry, and their monitors, such as the Philips 107S21, 107S20, 105B20, and 109S20, are prime examples of this commitment to quality and innovation. Each of these models possesses distinct features, technologies, and characteristics that cater to various needs, making them suitable for both professional and personal use.

The Philips 107S21 is a notable CRT monitor that offers a 17-inch display, providing ample screen real estate for tasks ranging from everyday computing to graphic design. One of its standout features is the 1280 x 1024 resolution, which delivers crisp and clear images. The 107S21 also emphasizes user comfort through a Flicker-free technology combined with a low Blue Mode, effectively reducing eye strain during prolonged usage. This makes it an ideal choice for users who spend long hours in front of a screen.

Moving on to the Philips 107S20, this model is designed for users seeking a balance between performance and affordability. It also boasts a 17-inch screen with a resolution of 1280 x 1024, similar to the 107S21. However, what sets it apart is its enhanced color reproduction capabilities, allowing users to engage in more vibrant multitasking and creative work. The model incorporates a SmartControl Lite feature, enabling easy adjustment of display settings and ensuring optimal viewing comfort.

The Philips 105B20 introduces users to a slightly smaller yet versatile option with its 15-inch display. Although it features a lower resolution of 1024 x 768, it compensates with excellent color depth and uniform brightness, ensuring that even smaller screens can deliver stunning visuals. This makes it practical for users with limited desk space or those who need a secondary monitor for additional productivity.

Lastly, the Philips 109S20 stands out as a larger 19-inch CRT monitor that can cater to more expansive workspace needs. It features a resolution of up to 1280 x 1024 as well, making it suitable for tasks requiring detailed visuals. With its built-in image enhancement technologies like Dynamic Contrast, this monitor ensures that darker scenes are portrayed with significant detail, making it appealing for multimedia applications.

Collectively, the Philips 107S21, 107S20, 105B20, and 109S20 deliver strong performance and diverse features that cater to various user requirements. Whether for business applications, graphic design, or general use, these monitors exemplify Philips' commitment to providing quality display solutions.
