The battle of flat-screen technology is heating up, and LCD makers are fighting each other for technological superiority.

As we reach the end ofthe production of toinch LCDs has grown, while pricing has reached parity with plasma displays in this size range. The list of competitive makers of LCDs in this size is exploding, creating a race to innovate.

Enter Philips' latest flat panel, the 42PFD. Aptura is designed to sharpen fast-moving images, solving one of LCD's common shortcomings. The 42PFD is a 1,by high-definition display with Ambilight Full Surround technology, Philips' exclusive Philips 42PF9831D78 LCD TV screen lighting system more on this later.

The 42PFD's biggest innovation is Aptura. The backlight is located in the back of the LCD panel and creates panel illumination.

In fact, it represents the first use of this technology in LCD panels. According to Philips, the use of HCF sharpens fast-moving images by reducing the hold time. Instead of illuminating the frame for its full duration, the screen is darkened for a portion of each frame. The overall result is darker blacks at about the same light output. The overall result is a rated response time of just 4 milliseconds, which is fast enough to reduce or eliminate motion lag, one of LCD's bugaboos. I take a closer look at motion in the Performance section ahead.

As I unpacked the 42PFD, I was immediately struck by its appearance, which is unlike that of any other flat-panel display. A shiny, all-black bezel Philips 42PF9831D78 LCD TV the dark-tinted, antireflective screen, and a white frame extends about 3.


The frame provides a white surface to reflect the Ambilight Full Surround screen lighting. Underneath each of the four sides of the black bezel lie red, green, and blue fluorescent lamps.

Similar in concept to sound-activated disco lamps that change color and intensity with the frequency and beat of the music, the Ambilight changes color and intensity by analyzing the picture content. For example, if the scene is a blue sky with white sand, the Philips 42PF9831D78 LCD TV will display blue on the top and sides of the screen and white along the bottom. Additional Ambilight controls increase peak brightness, tint, and rate of change. According to a Philips spokesperson, consumers overwhelmingly prefer the enhancement that Ambilight provides. That may Philips 42PF9831D78 LCD TV, but, to me, it felt like there was a disco light connected to the TV.

It was, in a word, irritating. There is an Ambilight control setting called Color, which allows the user to lower the light's intensity, change the lamp's tint, and maintain a constant illumination level with a near-neutral color 6, K. The latter was the most preferable position. With the room lights off, though, the Ambilight's brightness was still too high for my taste even in the lowest "0" settingso I chose the Off setting. Next, I adjusted the set's user controls and connected a number of sources. There is a CableCARD slot, so you can view standard and premium cable content without a high-definition cable box. I could tune in all of the channels using direct access via Philips' remote control.

The remote is slender but unremarkable, with no direct input buttons and no backlight. Its black-on-black color scheme made me wonder if anyone at Philips considered how difficult it is to identify the buttons in the dark. Performance Let's begin with signal processing. Standard-definition Philips 42PF9831D78 LCD TV fall around the middle of the pack in terms of the quality of upconversion. It is better than many sets I have sampled but not as clean as some others. In other words, it is acceptable but not outstanding for an HDTV. On the other hand, the TV has a number of issues with HD programs. First is the downconversion of i to the set's native 1,by resolution.

Instead of internally converting to 1, by p in the set's internal scaler, it processes each field of 1, by prior to conversion to p, which results in a loss of detail. Furthermore, the set will only process single fields using the 3: It also Philips 42PF9831D78 LCD TV a poor job of reducing jaggies in the diagonal-line test.
