We are about to purchase projection and screen equipment for our new village hall facility. We want to be able to: be able to play DVD and Blue Ray and project to a wall mounted screen. Link wirelessly to a laptop/tablet to project images, Powerpoint presentations and the like. The hall is large with a high apex ceiling; we wanted too suspend the projector rather than constantly balancing it on piles of books. This seems to imply a remote controlled system. We want a screen that is electric so that it is easily deployed and retracted. The room has little black out facility and has window on 2 sides and as roof-lights; our projector will need to have high quality projection in all lighting conditions. We want to purchase from a company who will supply, fit and commission the system. We want after-care so that when things go wrong we can get problems sorted quickly and easily. We have no expertise and would welcome ideas about how we progress this purchase safely and securely.
