Turned on prior examination of the projector, a mental note of what the digital projector can do for your company or organization, it is used and budget.

This parameter sets for retailers, enabling them to make sound recommendations.

For each digital projector, cross-comparison of these seven key points by awarding 10 points for each category, the one or two products to meet the required specifications should be:

Resolution

The highest screen resolution in pixels, resulting in a digital projector prices. Game of the projector, where it is needed and what is displayed.

PowerPoint presentations in small rooms or classrooms are generally at low resolution.

Brightness

These are dependent on the light output measured in lumens depend. An output of the projector with 1000 lumens can not give a clear picture. Presentations in rooms with brighter lighting need on the left probably a high-performance LCD projector.

Contrast

Contrast is the ratio between the darkest areas of the image. Refers to a ratio of 400:1 or more to get a balanced picture.

Portability

If a projector is static, not the weight does not matter, but if someone to carry equipment around the collaboration with the son and cable, a light in a difficult case, it is better. Portable digital projectors can be used in less than 5 kilograms, but less weight will come with a hefty price tag.

Connectivity

Find products that require an entry onto the projector and make sure the model has the correct jacks and plugs and a few spare. Look at the computer, as is also registered – it’s a Mac or a Windows computer and software for digital projector and / or drivers run on it?

All these factors must be considered in order to ensure to a projector offers maximum ease of use.

If prices are higher than expected, the digital projector could be a new model of decision-makers early pay over the odds, so the manufacturer can cover R & D costs.

Finally, do not make a quick decision – ask the dealer to offer a series of selection and request a demonstration in the hall, where the digital projector will be installed, if possible, is.

Digital projectors are the latest technology, including overhead projectors. The old model – the transparent projector works with light shining through a slide show or film, digital models and projects the image directly from the computer through a lens onto a screen. The latest model uses a reflective projector that delivers excellent image quality. This system is known as Digital Light Processing (DLP). Most theaters use projectors, the DLP technology. Intangible size of the screen are very high quality images.

Some digital projector rental companies believe a fact that there is no difference between LCD and DLP presentation, but there are some doubts about this belief.

In reviewing the rental of a digital projector, there are some things to keep in mind:

Do you remember always that you are renting a projector is used, so do not give some consideration to the type of presentation you plan to do to give
Think about where the presentation will be made. Whether a small room that could be blacked out or a large room where ambient light could be a factor?
All participants will be able to see the screen, or you need to rent a different screen?
Find out what accessories are included in the rent. Whether it is to contain cables, extension cables, replacement lamps, etc. are also
If you plan to transport equipment when it is light and portable.
Check to see if the cars are available if you need to take the projector and discard

The image quality depends greatly on the size of the room. Generally1000 lumens of brightness is ideal for small conference rooms in order, while larger rooms may require, from 1500 to 2000 lumens to overcome the prevailing light conditions. This function allows the presenter to have the lighting, which is good for security reasons. The data should be projected clearly and precisely. Some apartments may be a laser pointer that can be useful for presentations.

Before each presentation, it is preferable that you set up and test equipment. Make sure that the sharpness and brightness was adjusted. It is also possible with remote control for presentations, but it’s always better when it’s already happened. There are more professional, if the presenter can smoothly perform its presentation, rather than on the adjustment of the image.
