Getting to Know The Specifications of the Data Projector

Hiring a data projector is one of the options available to cater for your IT display requirements but it is worth being aware of the terminology describing projector specifications to ensure you get the best unit for your particular event.Brightness: The brightness of a data projector is measured in ANSI lumens starting between 1000 and 1500 lumens for a unit suitable for simple office or boardroom use, which is generally more than enough assuming the rooms lights can be dimmed and there is little or no ambient light.

For more brightly lit venues a more powerful data projector of between 2000 and 3000 lumens may be more suitable.Resolution: Resolution describes the number of pixels the projector is capable of projecting onto the screen. The higher the resolution the sharper the image appears on the screen. The majority of data projectors fall into one of two resolution categories - SVGA (800 x 600) and XGA (1024 x 768). Most computers also transmit an SVGA and XGA signal.Contrast Ratio: The contrast ratio of a data projector describes its ability to block out the projection lamp light. This translates into the depth of the black parts of a projected image. If you require an image of particular sharpness then contrast ratio should be a consideration.When using a projector it is recommended you use a projector screen to ensure the projected image is of a high quality. Projector screens are available in many sizes that are suitable for any venue. Projection screens are available with front or rear projection surfaces.Front projection screens dictate that the projector is positioned in front of the screen and this may be an issue for events where there may not be room in the audience to effectively position the projector or where aesthetics are a consideration. In which case a rear projection screen may be more appropriate and this allows the hire data projector to be positioned behind the screen.

Be aware though that although the projector is behind the screen the distance it has to be positioned from the screen will be the same. As such if there is insufficient space behind the screen to effectively position a standard projector then a short throw hire projector may be necessary.Other aspects to consider when deciding on the most appropriate projection screen for your event are -Size: Be aware of the height of or any fittings in the room in which the presentation is taking place that may restrict the installation of a large screen. The screen size may be 8ft square, but the total height of the screen including the legs may take the total height up to 10 or 12 feet.Front or rear projection: Front projection describes the positioning of the projector in front of the screen and as such will only require a normal projector screen.

Rear Projection describes the positioning of the projector behind the screen and requires a specialised screen type. Rear projection allows a reduced distance between screen and projector allowing for a thinner profile and reduces the likelihood of people moving between the screen and projector, disrupting the image.Once you know the projector specifications and screen for your event approach a professional audio visual hire company to discuss their range and prices. It may be the case that your budget is insufficient to cater for the size projector you require and as such you may need to alter your plans slightly.

It would be helpful to consult a salesperson who can provide you with information and translate certain technical specifications into words that can relate to your needs. Understanding projectors is simple if you have a basic idea of how it is used in various settings and occasions.

The bigger the size of your venue, the higher the capacity of the projector you need. The projector must be able to display crisp and clear images to people sitting in the front and those in the back row as well. In technical specifications, this is where resolution comes in. If you've noticed the specs that indicate "SVGA" and "XGA", these are computer display standards, which relates to resolution and display size. Projectors with high-resolution can showcase clearer and crisper images. With venues that are bigger like concert halls, auditoriums, churches, and convention centers, you need a projector that can display images beautifully on a big screen.The brightness aspect, which is known as ANSI lumens in technical specs, refers to the light output of your display. Low-light output or low ANSI lumens is okay if you will be using the projector in dark rooms with little ambient lighting. Ambient or natural lighting have the tendency to wash out the images or text displayed on the screen.

That is why for rooms with windows or venues set in the outdoors, a projector with higher brightness is recommended if you want achieve a great display despite the presence of natural or ambient lighting.ConnectivityWhen selecting your projector, always understand your full requirements. Aside from the venue, also look into function and connectivity. Know what the projector is for? For example, is it for a classroom set up or home entertainment system? A unit in a classroom set up would usually be connected to a DVD player, laptop, or perhaps an electronic whiteboard. Thus, what you need is a unit that is flexible to these common and standard devices.

If your facility or top-of-the-line home entertainment system is used for various other devices, you may have to consider more connectivity capacity.
