User manual PHILIPS 30099-31-16

[. . . ] Consult a service technician if the monitor does not operate normally when you have followed the instructions in this manual. The casing cover should be opened only by qualified service personnel. Keep the monitor out of direct sunlight and away from stoves or any other heat source. Remove any object that could fall into the vents or prevent proper cooling of the monitor's electronics. [. . . ] 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 a 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 optimise 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?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 file:///D|/My%20Documents/dfu/300WN5/english/300wn5/SAFETY/SAF_FAQ. HTM (7 of 9)2005-02-16 10:33:31 AM FAQs (Frequently Asked Questions) 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 ratio 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?In the event of difficult reception (snowy pictures) switch the NR on the PICTURE menu to ON. q Poor TV signal reception Abnormal picture seen from the screen q No TV picture No picture when TV input was selected Have you connected the aerial socket properly?Poorly connected SCART cables or aerial sockets are often the cause of picture or sound problems (sometimes the connectors can become half disconnected if the LCD Monitor TV set is moved or turned). Check all connections. q No sound No sound output when a program with sound was playing q Ensure that the audio cables are firmly connected to both the audio input connectors on your the LCD Monitor TV and audio output connectors on your PC or Video player. If on certain TV channels you receive a picture but no sound, this means that you do not have the correct TV system. Modify the SYSTEM setting.
