EDUCATION Replacement options for existing projectors Used in combination with interactive whiteboard Table-front application 0.6~0.8 Short throw 0.9~1.4 Mid short throw Typical LCD projectors, majority for education usage. 1.5~1.8 Standard throw Typical DLP projectors, majority for co-operate usage. 1.9~2.1 Standard throw PJD6381 PJD7383 PJD7383i PJD7583wi PJD7583w ViewSonic projectors have short throw ratios designed just for educational environments. In addition to enjoying premium image quality, surface exibility and instant interactivity, you also save the cost of reinstalling ceiling mounts. PJD5152 PJD5352 Throw ratio categorisation Over 2.1 (Long throw): Achieved by optional lens, used for large concert hall. 1.8~2.1 (Standard throw): Typical DLP projectors, majority for corporate usage. 1.4~1.8 (Standard throw): Typical LCD projectors, majority for education usage. 0.9~1.4 (Mid short throw): Table-front application. 0.6~0.8 (Short throw): Used in combination with interactive whiteboard. Under 0.6 (Ultra short throw): Use mirror technology to achieve, combines with interactive whiteboard.

In the education sector there is a global drive to improve results and few organisations are monitored to the same extent as schools. Providing the best possible classroom experience is part of the winning formula. n Cost: ViewSonic understands that education customers are cost-conscious and that there has to be a strong economic case for replacing equipment. It is also essential that technology purchases drive a strong return on investment against a low cost of ownership. n Resolution: With powerful graphics and displays available in even basic computers the image quality and resolution has increased. Plug those systems into a legacy projector and there is often a disappointing result. n Power: Projectors that are only a few years old will consume more power than many current models. ViewSonic projectors not only reduce the environmental impact but also have a lower operating cost, against a backdrop of mounting electricity costs. n Colour degradation: Over time projectors deteriorate and this becomes highly noticeable when new projectors are deployed alongside older models. As presenters and students move from classroom to classroom and use different solutions comparison is easy. n 3D: As 3D technology becomes more accessible and pervasive people will become accustomed to it and in the future it will become expected for teaching certain subjects. n Interactivity: Again people will become very accustomed to the interactive whiteboard and the benefits they bring so using a PC and projector will become a secondary solution. n Consumables: Replacement lamps for projectors are expensive and this adds to the overall cost. Also consider how affordable projectors have become in recent years and it starts to make sense to replace and recycle your old projector. n Facilities: Each service visit has either a direct or indirect cost to the organisation and this has to be taken into consideration - a newer solution will generally mean a lower volume of service visits. n Hidden costs: There are a host of costs that are more difficult to identify - for example, teachers wasting time sourcing alternative projectors, peer support and costs of rescheduling. 5
