FAQs (Frequently Asked Questions)

A:In a CRT monitor, a gun shoots electrons and general light by colliding polarized electrons on fluorescent glass. Therefore, CRT monitors basically operate with an analog RGB signal. A TFT LCD monitor is a device that displays an input image by operating a liquid crystal panel. The TFT has a fundamentally different structure than a CRT: Each cell has an active matrix structure and independent active elements. A TFT LCD has two glass panels and the space between them is filled with liquid crystal. When each cell is connected with electrodes and impressed with voltage, the molecular structure of the liquid crystal is altered and controls the amount of inlet lighting to display images. A TFT LCD has several advantages over a CRT, since it can be very thin and no flickering occurs because it does not use the scanning method.

Q:Why is vertical frequency of 60Hz optimal for an LCD monitor?

A:Unlike a CDT monitor, the TFT LCD panel has a fixed resolution. For example, an XGA monitor has 1024x3 (R, G, B) x 768 pixels and a higher resolution may not be available without additional software processing. The panel is designed to optimize the display for a 65MHz dot clock, one of the standards for XGA displays. Since the vertical/horizontal frequency for this dot clock is 60Hz/48kHz, the optimum frequency for this monitor is 60Hz.

Q:What kind of wide-angle technology is available? How does it work?

A:The TFT LCD panel is an element that controls/displays the inlet of a backlight using the dual-refraction of a liquid crystal. Using the property that the projection of inlet light refracts toward the major axis of the liquid element, it controls the direction of inlet light and displays it. Since the refraction ratio of inlet light on liquid crystal varies with the inlet angle of the light, the viewing angle of a TFT is much narrower than that of a CDT. Usually, the viewing angle refers to the point where the contrast ration is 10. Many ways to widen the viewing angle are currently being developed and the most common approach is to use a wide viewing angle film, which widens the viewing angle by varying the refraction ratio. IPS (In Plane Switching) or MVA (Multi Vertical Aligned) is also used to give a wider viewing angle.

Q:Why is there no flicker on an LCD Monitor?

A:Technically speaking, LCDs do flicker, but the cause of the phenomenon is different from that of a CRT monitor -- and it has no impact of the ease of viewing. Flickering in an LCD monitor relates to usually undetectable luminance caused by the difference between positive and negative voltage. On the other hand, CRT flickering that can irritate the human eye occurs when the on/off action of the fluorescent object becomes visible. Since the reaction speed of liquid crystal in an LCD panel is much slower, this troublesome form of flickering is not present in an LCD display.

Q:Why is an LCD monitor virtually free of Electro Magnetic Interference?

A:Unlike a CRT, an LCD monitor does not have key parts that generate Electro Magnetic

230w5 specifications

The Philips 230W5 is a standout monitor that embodies the blend of cutting-edge technology and elegant design, making it a compelling choice for both professional and personal use. Known for its superior display quality and ergonomic features, this monitor caters to various user needs, from graphic design to general computing tasks.

One of the most noteworthy characteristics of the Philips 230W5 is its 23-inch wide-screen display, which boasts a Full HD resolution of 1920 x 1080 pixels. This means users can expect sharpness and clarity that enhance the viewing experience, whether one is watching movies, playing games, or working on detailed projects. The monitor features an IPS (In-Plane Switching) panel, which provides wider viewing angles and more accurate colors compared to traditional TN panels. This ensures that the display looks vibrant and consistent from various angles, making it ideal for collaborative work environments.

The monitor is designed with Philips' SmartContrast technology, which dynamically adjusts the contrast ratio of the images being displayed. This results in deeper blacks and brighter whites, improving the overall visual quality, especially in darker scenes. Additionally, the PowerSensor technology is a remarkable feature that employs infrared detection to sense when the user is away from the monitor. It then automatically reduces the screen brightness to save energy, a blend of convenience and sustainability that appeals to environmentally-conscious users.

Ergonomics is another highlight of the Philips 230W5. The monitor comes equipped with height, tilt, and swivel adjustments, allowing users to customize their viewing experience to reduce strain during long hours of use. This is essential for professionals and gamers who are in front of the screen for extended periods.

Connectivity is also well-addressed, with multiple input options including HDMI, DisplayPort, and VGA, allowing for easy connection to various devices, from laptops to gaming consoles. The built-in speakers provide decent sound quality, further enhancing the multimedia experience without the need for additional external speakers.

In summary, the Philips 230W5 is more than just a monitor; it is a multifunctional device that combines impressive display technologies with user-centric features. Its Full HD IPS panel, SmartContrast, energy-saving capabilities, and ergonomic design make it a versatile choice for anyone seeking to upgrade their workstation or gaming setup without compromising on style or performance.
