Having a home cinema system with big sound, has been available for many years now. The feeling of being in a movie theatre but with all the home comforts is one of life’s pure joys.
Today, the sheer quality on offer is astounding, so I thought it might be good to bring everyone up to speed with the latest technology.
There are many components to building your own home theater system. Let’s start with a projector. For a picture as you see at the cinema you’ll need to get one that’s capable of 4K resolution. When we talk about 4K for projectors there are generally 2 specs: 3840 x 2160 or 4096 x 2160 pixels. The more pixels, the more vivid the picture contents are. Other than resolution, the technology that’s used inside your projector to produce the picture is important too. DLP is the leading projection display technology on the market. The DLP chip uses a technology called pixel-shifting, which can achieve true 4K resolution with 8.3 million distinct pixels. That is to say, a DLP 4K projector can bring you a cinema quality experience with true and accurate color and depth.
Another key piece to your home theater experience is the source, or what you’re watching. The best picture right now comes from 4K Blu-ray discs using a 4K Blu-ray player. While you may be familiar with Blu-ray, 4K Blu-ray discs have started making their way on the market and offer improved picture quality if you have the right setup to take advantage of it, meaning, a projector capable of 4K, a Blu-ray player capable of playing 4K, and a 4K Blu-ray disc.
So, what is true 4K?
According to CTA (Consumers Technology Association), 4K UHD must deliver 8.3 million distinct pixels on the screen, which is four times the resolution of Full HD 1080p.
What is XPR Technology?
DLP XPR Technology is Texas Instrument’s pixel-shifting technology that helps projectors to achieve true 4K resolution with 8.3 million distinct pixels.
What is the difference between XPR Technology and 4K-Enhancement Technology?
Although both XPR Technology for DLP projectors and 4K-Enhancement Technology for other projector mechanisms are pixel-shifting technologies, the results they produce are completely different.
• XPR Technology produces 8.3 million distinct pixels regardless of the DMD chip’s number of native pixels. In addition to doubling the 0.66” DMD’s 2716 x 1528 pixels, XPR also perfectly quadruples the 0.47” DMD chip’s 1920 x 1080 pixels to generate true 4K 8.3 million pixels with lightning-fast pixel shifting speed.
• 4K-Enhancement Technology can only produce 4.1 million pixels by doubling the native 1920 x 1080 pixel resolution, achieving less than half of the required 8.3 million pixels for true 4K resolution.

What do you need in order to enjoy 4K HDR?
• 4K Blu-ray player • BenQ 4K HDR projector
• 4K movies or 4K videos (4K UHD Blu-ray sets come with two discs: one 1080p disc and one 4K UHD disc. Be sure to use the 4K UHD disc.)
• HDMI 2.0 cable connected to HDMI1 port
What’s HDCP 2.2? Is HDCP 2.2 compatibility important?
HDCP 2.2 is a copy-protection file format, and all common Blu-ray discs are protected by HDCP 2.2. For those who want to enjoy a smooth Blu-ray disc viewing experience without any hindrance, all the DVD players, amplifiers, projectors and HDMI cables employed should be checked for compatibilities with HDCP 2.2 decryption, so as to ensure the Blu-ray discs to be played properly.
Can I stream 4K Netflix content with BenQ’s 4K projectors?
Yes. However, as explained in the question above, since 4K Netflix files are also protected by HDCP 2.2, meaning that for all the Netflix packages you’ve subscribed to, the audiovisual system, the projector, and the HDMI cables used must be compatible with HDCP 2.2. Also, an internet connection speed of at least 25 megabits per second is strongly recommended for an optimal 4K streaming experience. Furthermore, for 4K 60fps video contents, a 4K 60Hz-compatible HDMI cable is also required.
Follow these guidelines and a whole new world of quality entertainment will open up before your very eyes.
Happy viewing – and be careful not to wake the neighbours.
