Projection screens and 4K technology

We often get the question here at Strong/MDI: Are your screens 4K ready?These days, many screen manufacturers promote the fact that their screens are 4K ready, but what does that actually mean? What is 4K technology and can a projection surfaces be ‘ready’ for it? This article will shine some light on these questions.


What is 4K technology?


4K technology refers to the number of pixels projected on screen. A 4K picture projected on a cinema screen contains 4096 x 2160 pixels, which is actually 4x the number of pixels of 1080p projectors. In other words, 4K projects 4x more pixels than full HD, that’s 8 megapixels (8 million) pixels! 4K images reveal an incredible amount of detail and an extremely high contrast ratio. Images are crisp, well defined and details pop out. Simply put, 4K is the next generation of HD.


Can screens be 4K ready?


Screens reflect light (front projection) or diffuse light (rear projection). Their different qualities lie in their ability to do both these things. Specialized coatings increase reflectivity properties and surfaces of different shades of white grey or black are better suited for specific purposes and viewing environments. But can screens be 4K ready? The straightforward answer to that is: all surfaces are technically 4K ready.Actually, we can even say that the white wall in your basement is 4K ready. There are 4K projectors and 4K content, but no screen is specifically designed for 4K. The amount of pixels projected remains the same no matter what surface the image is projected on.


What to consider then when choosing a screen for 4K


Although all screens are 4K ready, there are some elements to consider nonetheless when choosing your screen. If using 4K projection, you will need a large enough screen to appreciate the fine details. You will also need to be seated at an appropriate distance for optimal viewing. Some surfaces allow for better clarity and improved contrast, be sure the screen you choose allows you to fully appreciate 4K. In short: an appropriate projection screen is essential.


It all comes down to choosing the right surface for your particular viewing environments by considering ambient light, screen size, projector capability, viewing angle and seating distance from the screen.
