LCD vs. DLP >>The Advantages of LCD Technology ( yamaha-club )

The Advantages of LCD Technology
One benefit of LCD is that it has historically delivered better color saturation than you get from a DLP projector. That's primarily because in most single-chip DLP projectors, a clear (white) panel is included in the color wheel along with red, green, and blue in order to boost brightest, or total lumen output. Though the image is brighter than it would otherwise be, this tends to reduce color saturation, making the DLP picture appear not quite as rich and vibrant. However, some of the DLP-based home theater products now have six-segment color wheels that eliminate the white component. This contributes to a richer display of color. And even some of the newer high contrast DLP units that have a white segment in the wheel are producing better color saturation than they used to. Overall however, the best LCD projectors still have a noteworthy performance advantage in this area. http://greateventsupport.com Sewa Plasma yamaha-club
LCD also delivers a somewhat sharper image than DLP at any given resolution. The difference here is more relevant for detailed financial spreadsheet presentations than it is for video. This is not to say that DLP is fuzzy--it isn't. When you look at a spreadsheet projected by a DLP projector it looks clear enough. It's just that when a DLP unit is placed side-by-side with an LCD of the same resolution, the LCD typically looks sharper in comparison.
A third benefit of LCD is that it is more light-efficient. LCD projectors usually produce significantly higher ANSI lumen outputs than do DLPs with the same wattage lamp. In the past year, DLP machines have gotten brighter and smaller--and there are now DLP projectors rated at 2500 ANSI lumens, which is a comparatively recent development. Still, LCD competes extremely well when high light output is required. All of the portable light cannons under 20 lbs putting out 3500 to 5000 ANSI lumens are LCD projectors. http://greateventsupport.com Sewa Plasma yamaha-club

LCD vs. DLP
The Technical Differences between LCD and DLP
LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one each for red, green, and blue components of the image signal being fed into the projector. As light passes through the LCD panels, individual pixels ("picture elements") can be opened to allow light to pass or closed to block the light, as if each little pixel were fitted with a Venetian blind. This activity modulates the light and produces the image that is projected onto the screen.
DLP ("Digital Light Processing") is a proprietary technology developed by Texas Instruments. It works quite differently than LCD. Instead of having glass panels through which light is passed, the DLP chip is a reflective surface made up of thousands of tiny mirrors. Each mirror represents a single pixel. http://greateventsupport.com Sewa Plasma yamaha-club
In a DLP projector, light from the projector's lamp is directed onto the surface of the DLP chip. The mirrors wobble back and forth, directing light either into the lens path to turn the pixel on, or away from the lens path to turn it off.
In very expensive DLP projectors, there are three separate DLP chips, one each for the red, green, and blue channels. However, in DLP projectors under $20,000, there is only one chip. In order to define color, there is a color wheel that consists of red, green, blue, and sometimes white (clear) filters. This wheel spins between the lamp and the DLP chip and alternates the color of the light hitting the chip from red to green to blue. The mirrors tilt away from or into the lens path based upon how much of each color is required for each pixel at any given moment in time. This activity modulates the light and produces the image that is projected onto the screen. http://greateventsupport.com Sewa Plasma yamaha-club

yamaha-club LCD vs. DLP =>know how (rental Projector)

LCD vs. DLP

Introduction
If you are new to the world of digital projectors, you won't have to shop around the market very long before discovering that "LCD" and "DLP" somehow refers to two different kinds of projectors. You might not even know what LCD and DLP are before asking the obvious question "which one is better?"
yamaha-club
The answer is simple. Sort of. LCD and DLP each have unique advantages over the other. Neither one is perfect. So it is important to understand what each one gives you. Then you can make a good decision about which will be better for you.
By the way, there is a third very significant light engine technology called LCOS (liquid crystal on silicon). It is being developed by several vendors, most notably JVC and Hitachi. Several outstanding home theater projectors have been manufactured with this technology, and JVC's LCOS-based

However the discussion of LCOS technology is beyond the scope of this article. For more click here <http://www.gesrental.com>.( yamaha-club )

yamaha-club Optimize HDTV => Contrast (rental Projector)

Optimize HDTV
Contrast
What it is: Also called picture or white level, contrast controls the intensity of the white parts of the image and determines the overall light output of the display.
How to set it: Display a still image from DVD of a white object with some visible details - such as someone wearing a white button-up shirt or a shot of a glacier from the Ice Age DVD. Adjust the control up all the way, then reduce it until you can make out all the details in the white (such as buttons on a shirt or cracks in the ice). In general, TVs look best when contrast is set between 30 and 50 percent.

Brightness
What it is: Also called black level, brightness actually adjusts how dark the black sections of the picture appear.
What it does: Excessive brightness can result in a two-dimensional, washed-out look with reduced color saturation. Images with brightness set too low lose detail in shadows, and distinctions between dark areas disappear in pools of black.
How to set it: Turn up the brightness to full, then reduce until just at the point you notice a loss of shadow detail - for example, when people's eyes disappear into the depths under their brows, then you've set brightness too low.

Some plasma, LCD, DLP, and LCoS TVs won't ever look black, so you'll need a setup disc to properly configure their brightness.

yamaha-club Optimize HDTV => Room lighting (Sewa Plasma ?)

Optimize HDTV => Room lighting

Room lighting
Since most people turn down the lights to watch a movie, our recommendations are designed to deliver a better HD picture in rooms with controlled lighting. Unless you have a big-screen projector or you're sitting at the minimum viewing distance, you shouldn't watch movies in complete darkness - it can cause eyestrain. For bright plasmas and smaller direct-view sets, the ideal setup is to place a dim light directly behind the TV and leave the rest of the room dark. Look for special "daylight" bulbs that glow at 6,500 degrees Kelvin. You should also prevent any light in the room from reflecting off the TV, as glare will hamper image fidelity. Watching at night is best, but if you watch during the day, thick curtains will really improve the picture.
Before you make any of the adjustments detailed below, set room lighting as if you were about to watch a movie. http://greateventsupport.com yamaha-club Sewa Plasma Jakarta bandung
