Alza Days - Projectors
- The campaign runs from April 7, 2026, to April 27, 2026 (“Campaign”).
- The list of products currently available in the Campaign (“Products”) can be found on this website below.
- A Product is considered purchased at a discounted price as part of the Campaign only once the order has been confirmed by Alza and the payment has been completed by the customer. Simply placing the Product in the cart does not constitute a purchase. If the Buyer selects cash-on-delivery payment, submitting the order to Alza within the Campaign period is sufficient, but the discount will only be valid upon successful payment upon delivery.
- Alza reserves the right to limit the number of Products a single buyer may purchase during the Campaign for certain items. Should such purchase limits apply, Alza's system will automatically prevent buyers from adding more Products to their cart than the permitted purchase quantity for the duration of the Campaign.
- Available stock of select Products will be allocated among consumers in the Czech Republic, Slovakia, Austria, Hungary, and other countries served by Alza.
- Discounts on Products are valid only during the Campaign period or while supplies last. Alza reserves the right to change the selection of discounted Products at any time during the Campaign.
- The general terms and conditions of the Campaign can be found here.

Alza Days - Projectors
Projectors are excellent presentation tools as well as perfect home cinema devices. They can be easily connected to DVD players and computers, so you can sit back, munch popcorn, and enjoy great cinematic experiences in the comfort of your own home.
Projectors typically have many input signal options, featuring composite, S-Video, VGA or HDMI. You can project on plain white walls, but to get the best performance, choose from the range of professional projection screens available. Depending on the way in which they process the internal video signal, projectors are either LCD or DLP. Although these technologies are different, and LCD projectors used to be considered better for projecting data from computers while DLP models were ideal for screening films, today both technologies are practically equivalent.
LCD Projectors
The light source in LCD projectors passes through three primary colour filters. Each then passes into one of three LCD panels through a permeable layer. Finally, all three colours are combined again and projected through an optical device onto a screen, where they are displayed as a complete picture. These devices are both lightweight and easy to maintain.
DLP Projectors
DLP projectors work with DMD chips and use a large number of microscopic mirrors, with each mirror representing one pixel. The image is again broken down into the three primary colours (red, blue, green) and then passes through the micro mirrors and lens before being projected onto a screen.
