Projector is used more and more widely, not only in some business occasions, but also in many people's home film systems. But most people don't care much about how to use the projector correctly.

In fact, there will be many small problems in the use of the projector. In addition to the basic installation and maintenance, there will be some puzzling occasion in the use of the projector, which will make the user misunderstand the projector. Today, I'll explain the common problems that the projector occasionally has, so that users won't be too flustered in the use process.

The first is about sound.

Many users will be confused about the sound when using the projector. The speaker of the projector is very small. The main function of the projector itself is to show the perfect picture, and the loudspeaker takes up too much internal space, so the loudspeaker design of the projector will be relatively small, so it is better to cooperate with the external sound equipment when using the projector. At present, most of the projectors on the market are equipped with sound output terminals, which is also fully prepared for the external sound equipment.

Secondly, the brightness of the projector.

Many users responded that the projection screen was not as bright as before after the projector was used for a period of time. They asked if there was a quality problem with the projector. Actually not. At present, most projector products use the built-in bulb penetration projection mode, and the projection brightness is mainly determined by the bulb, while the display brightness of the projector's bulb is inversely proportional to its use time. Generally speaking, after 120 hours of use, the brightness of the bulb will drop by 20% - 30%. Therefore, users must pay attention to protecting the projector's bulb in normal use. Do not use it for a long time. Try to turn off the projector when not in use.

Finally, the problem of the picture.

Sometimes the projector has the state that image is unstable state, or the picture blurs and shakes. This is also not a problem with the projector function. Some tips are needed to solve it. First look at the image instability.

The output image of the projector is unstable and has stripe fluctuation, which is mostly due to the inconsistency between the power signal of the signal source and the power signal of the projector. The user needs to plug the power of the projector and the signal source into the same terminal block, which can basically solve this problem.

The condition of blurred and dithering picture. Generally speaking, if the projector is too far away from the signal source, it will weaken signal, and the performance projected on the screen can be blurred or dithered. So when using the projector, it is noted that the distance between the signal source and the projector can not be too large. If the distance between the two is large, it is recommended to use a signal amplifier to help the projector receive the signal from the signal source.

Picking out the best projector can definitely become a headache for many. People usually think that going to a showroom and browsing projectors at a time can be tiring as you don’t have enough knowledge about the topic. However, you need not worry about anything. Here we present you the ten best ways to pick the right projector for you:

PICK THE PROJECTOR THAT CURBS YOUR REQUIREMENTS

To be precise, there are three kinds of projectors in the market, namely Home Theater Projectors, Business Projectors, and Pico Projectors. Home Theater Projectors usually project wider content and emphasize on image quality and high contrast as they are fit for in-home use. Business Projectors are meant for projecting ppts during Business Meetings and Conferences. On the other hand, we have Pico Projectors that are generally used for gaining portability as you can carry them wherever you go. Make a wise choice as per your requirements.

PICK THE PROJECTOR OF THE RIGHT TYPE

The three most general types of projectors are DLP projectors, LCD projectors, and LCoS projectors. DLP projectors are lightweight and are good for having a smooth projection of video content that can project fast-action scenes with ease. LCD projectors are generally brighter whereas LCoS usually cover everything.

PICK THE PROJECTOR WITH GOOD LIGHT SOURCE

Projectors typically use a standard lamp, laser, or LED for light projection. It is often recommended that you opt for LED projectors instead of ones with a standard lamp. The laser projectors are energy efficient and offer better outputs too, but still LED ones are safer for the eyes.

PICK THE PROJECTOR WITH THE PERFECT ASPECT RATIO

The aspect ratio plays a significant role in achieving the drool-worthy picture quality of a good projector. You may find a lot of attractive projectors in the market. However, very few of them manage to project good quality video content on the big screen. Even though 4:3 projectors are cheaper, 16:9 are better for high picture quality.

PICK THE PROJECTOR WITH THE RIGHT RESOLUTIONS

Yet again, the debate about getting high quality projected video content continues. The resolutions of the projector vary in accordance with the aspect ratio. For 4:3, we have SVGA (800x600) and XGA (1024x768). On the other hand, for 16:9, we have standard HD (1280x720), WXGA (1280x800), and Full HD (1920x1080). 16:9 and Full HD make up for a great combination for achieving high quality projected video content.

PICK THE PROJECTOR WITH THE GOOD BRIGHTNESS

Brightness plays a significant role in the projection of video content. A projector with good brightness can make up for a great video watching experience for the user. Remember that brighter the light, the better the color. The vibrant color won’t impress you unless they are cast in a more colorful frame. Especially for business Projectors, you must have high brightness.

PICK THE PROJECTOR WITH THE REQUIRED CONTRAST RATIO

It is the difference between the darkest and brightest areas of your projected video content. For getting better details out of your projected video content, a good projector must have a defined contrast ratio that can highlight the presence of shadows, in turn, enhancing the picture quality. You’ll know the worth of contrast ratio mostly while projecting video content in darker rooms.

PICK THE PROJECTOR WITH EXCELLENCE THROW RATIO & LENS ZOOM

Throw ratio is critical at times when you are planning to mount the projector right as it decides how much wide image is going to be cast on the screens. In such cases, short-throw projectors are the best as even if the projector is closer to the screen; a wide image will be cast on the screen. The lens zoom avails the user to adjust the size of the screen which can help you out if you have a pico projector in your vicinity.

PICK THE PROJECTOR WITH THE PRODUCTIVE CONNECTIVITY OPTIONS

You might find the need of connecting external devices to your projector now and then. In such cases, you should have the productive ports that can avail you to connect external devices to your projector. Therefore, you must confirm that the projector has important ports such as USB port, HDMI port, VGA port, SD card slot and other ports that should be present for allowing you to connect the devices you own with the projector you’re about to buy.

PICK THE PROJECTOR WITH NICE FEATURES

Features such as Keystone Correction and Lens Shift might help you a lot in enhancing your experience while using a projector. These features will help you in deciding the screen orientation and adjust the image on projectors with ease. In addition to these, you can also opt for projectors that support 3D technology as in the end having a good experience while using your projector is all that actually matters. Wireless projectors and adapters are a good option as well.

This is it for now. Have a fun time choosing the right projector for you!

Brightness is the light intensity that the projector product outputs to the screen, and also the brightness of the projected image. In general, the higher the brightness of the projector, the brighter the image of the same size projected on the screen, and the clearer the image. However, the brightness of the image that our eyes can perceive is not only determined by the brightness of the projector, but also greatly related to the intensity of the ambient light and the size of the image. The stronger the ambient light, the dimmer the brightness of the image perceived by our eyes. Therefore, users must choose the appropriate brightness according to the environmental conditions of their projector. It is not necessarily as bright as possible. In the case of the same other indicators, the higher the brightness is, the higher the price of the projector will be. At the same time, the brightness of the image perceived by our eyes will have a certain range. Beyond this range, the our eyes will feel uncomfortable, especially after watching the image with high brightness for a long time. Our eyes will feel tired and may get hurt to some extent.

It is necessary to remind the user that in addition to choosing the brightness index according to the space size, the user should also consider the lighting conditions of the use environment, screen type and other factors. Under the same brightness, different ambient light conditions and different screen types will produce different display effects. When users choose projector products, they should have a margin for brightness index. Because the brightness of the projector largely depends on the light bulb in the projector, the brightness output of the light bulb will decline with the use time, which will inevitably cause the brightness of the projector to be declined. After 2000 hours of use, the brightness of the projector product decays rapidly, so when users choose the projector product, they must have a comprehensive consideration of the brightness index.

Generally speaking, in the 40-50 square meters of home or reception hall, it is recommended to choose 800-1200 lumens for projector brightness, and 60-72 inches for screen; in the 60-100 square meters of small conference room or standard classroom, it is recommended to choose 1500-2000 lumens for projector brightness, 80-100 inches for screen; in the 120-200 square meters of medium conference room and ladder classroom, it is recommended to choose 2000-3000 lumens for the brightness of the projector, and 120-150 inches for the screen; in large conference rooms or auditoriums with an area of 300 square meters, professional engineering machines with an area of more than 3000 lumens should be selected most projectors, and the screens should be more than 200 inches.

The book scanner is a kind of computer input equipment that can input image data into the computer. Pictures, photos, films, drawings and all kinds of documents can be input into the computer by the scanner and stored in the form of pictures. Some people vividly call Book scanners "the eyes of computers". Document management is the most widely used field of scanners.

The book scanners can also cooperate with optical character recognition software OCR (optical character recognition) to convert scanned documents into computer text form. It omits a lot of manual input time.

The concept of scanner resolution: scanner resolution is divided into optical resolution and maximum resolution. The maximum resolution is equivalent to the interpolation resolution and does not represent the true resolution of the scanner. Therefore, when we purchase scanners, we should take the optical resolution as the judgment standard.

The resolution unit of the scanner is DPI. The maximum optical resolution of the scanner is multiplied by two numbers, such as 600 × 1200 DPI (also known as 600 × 1200 line). The former number represents the lateral resolution of the scanner, i.e. optical resolution, which is determined by the CCD performance of the scanner. The latter number represents the vertical or mechanical resolution of the scanner, which is the resolution of the stepper motor used by the scanner. When judging the optical resolution of the scanner, we should take the smallest one as the criterion.

Resolution is the main technical index of the scanner. It represents the ability of the scanner to show the details of the image, which determines the fineness of the image recorded by the scanner. The higher the resolution of scanning, the higher the quality of the scanning image, but there are limits. When the resolution is greater than a certain value, it will only make the image file larger and not easy to process, and it will not significantly improve the image quality.

In practice, the higher the resolution setting, the larger the scanned file, and the slower the scanning speed, which is not convenient for management and saving. Therefore, we seldom use the highest resolution of the scanner in actual scanning. We need to use different resolutions according to the nature of the document. The general settings are as follows:

1. In the category of photos, the reso lution of 350-400 is adopted, some of which are particularly important, and even the resolution of 600 or higher can be adopted.
2. Detection report, business license, code certificate, etc., with 300 resolution.
3. Some important documents (such as archives, files, ancient books, books, etc.) adopt 300 resolution.
4. The resolution of 300 shall be adopted for engineering visa documents.
5. General contract text, text records, etc., with a resolution of 150 to 200.

Therefore, when choosing a scanner, the scanner with 600 resolution has fully met the requirements, because in general, we can use up to 300-400 resolution. Use 600 resolution in special cases.

When the book scanner is in use, the scanning range can be adjusted by dragging the mouse, and the resolution can be set according to the needs, so the operation is very simple.
