Insight Media has released a white paper titled Understanding 4K Resolution in Projection Systems. It discusses the changes that are occurring with regards to defining resolution in projection systems.
This is being driven by the wider adoption of so-called “image shifting” techniques which can increase the displayed pixels on the screen – which are higher than the native resolution of the projection engine. This white paper explores the technologies used in image shifting as well as their performance. It also defines categories for better understanding evaluation of these products.
In sight said that ror this paper, it defined resolution categories with definitions that focus on what can be resolved on-screen, which the firm thinks is the correct way to evaluate and measure projector resolution. The categories are:
- 4K DCI (4096×2160): accepts 1080p or 2160p content and displays 8.8M pixels on-screen with or without an image shifting optic.
- 4K UHD (3840×2160): accepts 1080p or 2160p content and displays 8.3M pixels on-screen with or without an image shifting optic
- 4K Supported: accepts 1080p or 2160p content and displays around 4M pixels on-screen using an image shifting optic
There are noticeable differences between projections in different classes and even within the same class – most determined by the algorithms used. The white paper can be downloaded (registration required) – click here.
