TCO Image Size – the solution when purchasing a projector
Yesterday I promised all of you more information related to our latest certification TCO Certified Projectors 1.0. Today I explain the main reason to why TCO Development decided to develop TCO Certified for projectors. …..The amount of question on projectors increased– what to think about when buying a projector and how to adjust the projector to get the optimal picture were common questions. Good picture quality and low noise are key factors when choosing a projector. During our development we found:
• Product specifications presenting an extensive list of values that most people have difficulties understanding.
• Most values presented are measured with the projector set to its extreme to maximise this single value. This means that neither are the values true information nor are product specifications possible to compare.
• Trying to understand how to combine the values to choose projector for the intended use is a challenge.
We also know that some parameters need to be within a certain range to produce a high quality picture. Those are; light output, resolution, contrast, black level, luminance uniformity, colour temperature, RGB colour gamut and colour gray scale.
Another important parameter to consider when buying a projector is in what ambient lighting condition the projector will be used in. With these issues in mind we found that most users knows how big picture size they want to have and if the projector will be used for watching film or show PowerPoint’s on. The solution is TCO Image Size – the maximum area for which the projector has been tested with all important visual ergonomic criteria considered for producing a high quality picture. TCO Image Size is tested for two ambient lighting conditions office and video. With lightning condition office the room is enlightened to allow you to take notes. In lightning condition video the room is dark but not darker than you are able to get another cup of coffee without falling over you best friend.
Conclusion – when buying a projector in the future you only have to ask for TCO Image Size for office or video purpose.
