Choosing a LCD 14300 Lumen Projector
A high lumen count is essential for projectors that will be used in ambient light. It allows the projector to overcome a wide range of ambient light levels, so users can experience their favorite content in almost any environment.
The ANSI lumen spec can be misleading because it does not take color brightness into account. As shown here, the LCD is able to generate much brighter colors than the DLP at its rated ANSI white brightness operating mode.
Brightness
A high brightness is crucial for a projector to display images on a large screen. The screen size and ambient light levels determine the optimal lumens for a given scenario. Usually, a projector with about 3000 ANSI lumens can overcome ambient lighting and display quality images on a screen up to 100 inches.
While ANSI lumens are a useful measurement for white brightness, they do not take color brightness or contrast into account. This is the reason why ANSI lumen ratings can be so misleading, especially when comparing projectors from different manufacturers. The ISO lumen, on the other hand, is a more accurate measure of lumens for projectors. It uses strict production and measurement standards that provide more consistent and reliable results.
Regardless of how a projector’s lumen output is measured, it is important to consider the specific needs of a given environment when choosing the right one. For example, a classroom setting may require a higher lumen rating than a home theater room. In addition, the wattage of the lamp used to produce the lumens should be considered.
While the promoters of the CLO spec are correct that the ANSI lumen rating is flawed, they overlook the fact that it can be made to work well by making certain adjustments. These adjustments include reducing the Brilliant Color control to lower the white light level, which decreases ANSI white lumens while increasing CLO color lumens. The result is that the resulting image is a bit overdriven in the highlights, but it has sufficient brightness for a classroom setting.
Contrast
Contrast is a measure of how lcd 14300 lumen projector dark or light an image appears. A projector with high contrast produces deep blacks and bright whites, rich natural color saturation, sharp shadow detail, and a deeper three-dimensional image. Poor contrast results in muddy or grayish shadows, dull colors, and less than crisp whites.
Typically manufacturers report their contrast ratios using Full On/Off contrast measurements which are done in a completely dark room by comparing the brightness of a black image to a white image. This is a much easier measurement to make, and it allows manufacturers to inflate these numbers. They know that consumers are obsessed with these specs, and that a higher number equals more sales.
The problem is that Full On/Off contrast does not tell you anything about how well a projector can perform when viewing real content in a typical home environment. This is because your eyes adjust to the ambient and reflected light in a room, reducing the perceived contrast. A good comparison of two different projectors in a side by side test will show that it is not simply the higher Full On/Off contrast that matters, but rather how the images look in normal viewing conditions.
To see how a projector will look in your home, read and watch online reviews from respected influencers who have tested these models with real video content. Also try to attend in-person demos at retailers and professional equipment vendors, so that you can compare the projectors side by side and actually see how they look in a normal viewing environment.
Colors
A big flaw of the ANSI lumen specification is that it doesn’t take color brightness into account. A projector may be able to make white patterns brighter than a competitor, but this doesn’t tell you anything about how well it performs with real world full color subject matter.
Unless it is calibrated to remove the undesirable blue/green tint and reduce contrast to regain highlight detail, an LCD projector can have trouble with some colors. For example, on the test pattern above, the LCD interprets the background as blue, while the red pencils look dimmer brownish red. The white reflection glare on the glass also looks dimmer on the LCD. With the proper adjustments, these problems can be corrected on the LCD to some extent, but it takes a lot of power to do so.
The young woman’s face on this scene shows the weaknesses in the LCD’s red channel. This can cause light skin tones to look drab gray-green, or to have a greenish cast to them. Even after calibration to reduce this effect, the LCD’s weak color brightness limits its ability to render pastel colors accurately. The blue ball in the center is more teal than blue, and yellows show a strong olive green bias. This can be resolved with adjustments, but it is an example of why the CLO spec is important, as it can point out these color weaknesses that the traditional ANSI lumen spec ignores.
Noise
Many projectors emit a lot of noise from the cooling system, and this can be distracting. However, some of them have a built-in noise reduction technology that can help reduce Portable Projector this noise. This technology helps to eliminate the noise and ensure that the picture is clear and crisp. This can be an excellent feature if you want to watch a movie without being disturbed by the noise.
Leaving aside color accuracy for the moment, it is easy to see from this that the ANSI lumen spec does not make any distinction between the brightness of LCD and DLP projectors when it comes to full color content. This is exactly what advocates of the CLO spec are trying to point out.
When a projector is set up to maximize white light output it sacrifices image quality by blowing out highlight detail and causing colors to be overdriven. This is an example of why a DLP projector often outperforms an LCD in the areas of black level, contrast, and image sharpness. The DLP can even outperform an LCD in the area of dark scene detail, as demonstrated by this shot of a couple of wine glasses. After calibration this picture looks much more successful on the DLP, though it is still not home theater perfect in the highlights. The DLP can be adjusted further to reduce the overdrive in the highlights but that will also have an impact on the overall brightness of the picture.
