How Do 4K Projectors Work?

4K is a term which refers to an image resolution (the number of pixels that make up the image of a digital screen) of 4,000 horizontal pixels. This is close to four times that of the current home media standard of 1080, delivering a potential picture quality similar to what you get from the most high end of movie theaters. Though pricy, there is a growing trend towards movie buffs, sports enthusiasts, or even pro gamers with an interest in maintaining upscale home theaters wanting 4K projectors in their home for the maximum possible image quality.

4K projection is made possible by the use of a tiny grid-like chip usually just under two inches in size which is comprised of microscopic mirrors that take a video signal and reflect them out through the projector lens. This is exactly the same as any digital projector, the only real difference being that the chip used to reflect the image is made up of many more mirrors of a much smaller size than usual.

The Internal Stuff:  How Do 4K Projectors Work?

Just as with computers and portable storage devices, the technology of projection has become more and more powerful while also requiring less overall material to work. Companies such as Texas Instruments have been at the forefront of making this possible, and we are sure to see more improvements in possible image quality as time continues marching on.

This is perfect for high definition sports games with lots of fast action occurring on screen. At more standard resolutions, you will typically see motion blur, whereas 4K can handle quick motion with staggering fluidity.

It is also worth noting that motion pictures are moving towards a trend of filming with high frame rates such as 60 frames per second (vs the traditional 24) like the recent blockbuster film The Hobbit. Only the likes of 4K projectors will be able to accurately recreate that level of image quality at home. 4K projectors usually come with 3D and anamorphic widescreen options as well, making them incredibly ideal for matching the current quality of mainstream cinema.

4K projectors are only a growing trend and as such are still on the expensive side (such as the Sony 4K Home Theater Projector ES which retails for $25,000) but they will undoubtedly play an important role in the home cinema experience moving forward.
