In order to adequately prepare for the new school year and enable their students to acquire new knowledge via modern teaching methods, at the request of the school management, AVL Projekt equipped the classroom with professional video system with performances that enable uninterrupted use throughout the day.

Sony VPL-PHZ50 laser projectors are a great choice when it comes to the ratio of quality they offer and price. They are characterized by a light output of 5,000 lumens, highly saturated colors and a service life of at least 20,000 hours. They have an intelligent adjustment function that allows control of several parameters (color, lighting, fan noise, etc.) thus maximizing projector performance, as well as the Bright View function that further enhances the lighting for spaces with higher ambient light.

Contrast Ratio (full white/full black) of 00:1enables an extremely crisp image.

They are very small and lightweight, and thanks to the adjustable vertical lens shift from -35% to + 55%, they are very flexible during installation.

They support 4K @ 30Hz input resolution and do not require additional converters to scale the image to HD resolution, which allows them to be combined with 4K monitors to make the video system affordable and high quality.

The maximum noise level of the projector in standard mode is less than 35 dB, so its operation in no way interferes with classroom lectures.

Thanks to the HDBaseT input, the transmission of AV signals is easy via a network cable without interference under the influence of electromagnetic radiation.


The installed laser projectors will enable teachers at the school to make their lectures more vivid and interesting, while students will find it easier to acquire new knowledge and get the highest grades.
