Foreword:
Friends asked me some time ago, saying that their company was going to replace the tv for the meeting, so they wanted to ask me if i had recommended it。
It probably means that television is not easy now, that the screen is too small, that colleagues in the back of the meeting room can easily lose sight, that they sit on the side and look at the screen during the day. If you want to switch to a big tv, it'll cost thousands more, and it'll cost more. Ask me if i can recommend a big screen with a high pay。
I'm sure it's the most appropriate projection for a big picture to be cheap. I asked a few of my friends, and i found that basically large and medium-sized companies still use more projectors, and i've come into contact with more companies using projectors, so i finally recommended to my friends a commercial projection that could be used during the day。
What's the difference between commercial projectors and television
As we all know, procurement and administrative staff for commercial purposes in conference rooms face the problem of the choice of projectors and television sets。
The choice depends on the difference。
Size: the first is size, the tv is fixed, the size is the size. Many companies have a budget of about 3,000, and generally only 65-75 inches of television. This small television set up in a conference room, meeting for more than five people, would not be very effective and could result in colleagues in the back row losing sight of the screen。
The projectors, on the other hand, are more flexible in size, are focused, and projectors vary according to their own needs and are well suited to the commercial use of conference rooms。
Flexibility: then flexibility: televisions are much heavier than projectors, with fixed positions, fixed angles, and, in many cases, there is no way to move to a larger conference room for meetings, and projectors are much more flexible, with the ability to board tables and move between rooms。
Image effect: tvs are usually better visible and brighter than projectors, but tvs still have a reflection, flaunting, disillusionment and incomplete presentation of content information。
And the projector, because it's a reflection, has no reflection. And now that the projector's brightness has increased significantly, some of the professional commercial projectors have reached nearly 4,000 luminous levels, and in the daytime or in the conference room where the lights are turned on, a clear picture can be shown, without fear of “light death”。
Appearances: as we all know, television links are very numerous, especially when some are in the front zone of the television, people move around, and they can easily be kicked out, leading to interruptions of meetings and even affecting the state of conference personnel。
The projector has a very small surface area, in particular a projector that supports wireless screens, with few lines and ready to move to suitable locations, which are both beautiful and convenient。
Systems: traditional televisions are very entertaining, usually have open advertising, home page video recommendations, and wireless screen set-up requires half a day, which is very cumbersome and affects the conduct of meetings, especially in the presence of a., which greatly affects his or her professional feelings。
The use of projectors has become more professional, with no advertising on the home page and the design of the home page being very simple, with various connections to the home page, such as screens, disks, mobile computers, and so on。
Iii. Under what circumstances does the commercial projector be selected
In the case of executives and purchasers, the equipment of the conference rooms, depending mainly on the size of the conference rooms and the number of meetings, is recommended for not choosing televisions, which are basically five or more, and are roughly 60-75 inches in size, a television opportunity of this size that leads to a lack of visibility of the screen by colleagues in the back row or on both sides, and to a deterioration in the quality of the meetings, since, in many cases, we do not go on our own initiative and opt for vague meetings without focus。
Retrospect projectors are much more helpful to conference rooms than television, and we have the image presentation, the flexible size, and so on。
How do you choose a good commercial projector
Now that we have to choose commercial projectors, how we should choose them, we have to give the basic information about the projectors. It is important to note that it is not only projectors that guarantee the advantages described above, for example, some household projection, because the light is just over 2,000 fluent, so the light is not visible。
This brings us to the selection points of the commercial projector, which help to distinguish between the selected commercial meeting projectors at the time of procurement。
1. Projection brightness: the resolution brightness is in [streaming]. The brightness test has two criteria: ansi, us national, iso, and international. In the selection of purchases, reference to more stringent iso standards is more recommended。
2. Resolution and contrast: the resolution is divided into svga, xga, 1080p, 4k, etc. The higher the resolution, of course, the better it is, but the higher resolution usually comes with higher prices, and you need to choose within your own budget。
When the resolution is the same, the projector with a higher contrast is selected. Because the higher the contrast, the higher the difference between black and white, the text of the high contrast projector is clearer and sharper at the same resolution. Therefore, contrasts are also a non-negligible parameter for viewing ppt and meeting scenes with a relatively large number of statements。
3 visible technology: visibility technology is divided into dlp display technology (digital projector), lcd single display technology (i. E. Lcd projector), 3ldc display technology, and lcos display technology。
The projection of dlp technology is more recommended for commercial offices, taking into account both useful life, performance and cost。
In conclusion, there is a need to focus first on the quality (light, resolution and contrast), brand (visibility + after sale) and, if used in a client-oriented manner, to make the meeting process more professional, fluid and efficient, the system design of the projection should also be sensitive to the need to internalize the ui for commercial design and not to advertise, and the use of functions such as wireless screens and document reading on the front page, with instructions。
V. Any recommended models for commercial projectors
If you say so much, you may not know how to choose. This is a direct recommendation for a good commercial projector and, finally, a model for a friend: a commercial projection of the light e series of light-based smarts. Friends finally chose e-540. I'm just borrowing a friend's machine to make an evaluation。
If you want to choose a commercial projector, the first is to know the brand. In particular, for procurement, there is a need to select a secure brand after sale。
In the field of specialization, the ming foundation, a major specialized group company established in 1984 in the field of digital media and web communications, has a rich technological base, with its main product areas being projectors, commercial monitors, etc。
The machine in the minkye series is a two-year machine, and there are multiple offline sites that can be repaired near and sold well。
Here's to sharing the experience of the practical use of the minky e540 commercial projector:
Appearance:
The first thing i felt when i got it was small, because i was surprised to know that the product function was that it would be heavy, and that it would weigh 2. 6 kg。
The outer design is more business-like, with physical buttons on the top of the fuselage, very intuitive designs that can be used at a glance, with the design of wind vents and heat vents on both sides, and the grid surfaces used at the top of the fuselage are not only highly visual but also very sensitive。
The fuselage is followed by a line access and signal booster antenna (which provides a free-screening function with its own hot spots), which can be described as very practical。
Functional highlights:
1. Brightness
As a commercial projector, the most important issue for administrative and procurement staff was the question of effectiveness. The primary effect of the projection is to see the quality of the painting。
E540 has a brightness of 4,000 isos, a high-light mix of 0. 55 dmd chips, greater light fluxes and a real high experience。
I'm going straight to the white wall, without curtains, and it's working very well during the day, with sunlight in the house, it's very clear on the screen, it's very clear in pictures and text, but it's a little more clear in the eyes than on the phone。
2. Contrast
The biggest visual expression is the presentation of the text numbers on the screen, which are basically very small. Using dlp digital imaging technology, e540 has a high natural contrast, with an actual 12,000:1 high contrast and a full glass lens, which is used for long periods of time。
For commercial projectors, dlp shows that technology is also a very important element in the selection. It is important to keep in mind that the projection of the dlp technology is given priority in the case of frequent textual, numerical and other intensive texts。
3. Focus
Actually, i like to focus manually, it's simple, it's got two gears on the top of the fuselage, and it's easy to slide. The biggest highlight of e540 was 1. 3 times greater, achieving a 4:3 painting with 100 inches for 3 metres, and a smaller magnification would achieve no-lost quality。
If you have a bigger room with a projection distance of up to 4 metres, you can consider the e520 in series e, which is also a high-light projector, but at a lower price。
4. Life expectancy
Smarteco has its own smart and environmentally efficient technology, which saves 70 per cent of energy consumption, with a useful life of 10,000 hours and an extended life of 125 per cent of light bulbs, without compromising paint quality。
Also, because of the dlp technology, the chip is designed to be sealed, without fear of damage to the panels resulting from the accumulation of dust heat, prolonging the projection life and reducing the maintenance costs of the worse filters. In this technology, for a company, it's in the realm
5. System operations
E540 is a very intuitive business-style ui interface. The four larger sections above are: straight-link, computer, mobile, document management。
There's no ad for the whole thing. It's very simple. Each step of the projectile, file transfer, etc. Function has a short text description, which can be operated independently, even by colleagues who have never used a projector。
There is also a high degree of compatibility with the screen, whether it's an andre, apple system cell phone, tablet, or mac, windows computer, which can be placed indefinitely, or can be connected directly to the computer with a hdmi line, or can read office documents, pictures, videos from the disk。
If there is no network environment, but there is a need for a screen cast, you can select the first page of the projector's own hot spot for a wireless screen。
Overall, the efficiency with which e540 is used is good for companies。
Finally, an e540 product parameter chart is attached for your information:
Summary:
Commercial projectors continue to be the main force in conference rooms today because of the advantages of large images, relatively low prices and more professional simplicity. It is therefore suggested that if the conference room is for five or more, it would be better to choose a professional commercial projector。
The e540 commercial projector that was tested today is part of the classic commercial series e series, which is based on the mixed base, an old projector. The whole series is high-lighted, smart, so it's good to show results during the day, and it's easy to operate. If the budget is not high, the room is more than 3 metres away from the projection, and option e520 is recommended。
The same series of e582 and e592 may be considered if it is desirable to have a better quality and a higher budget。
