XPR Technology achieves true 4K by producing 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.
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.
FACT #1 –PRO-UHD has only 50% of the resolution compared to 4K UHD
For most products, using the word “Pro” or “Enhanced” in front of the industry-standard usually means that the product has been improved over the standard in some way. However, when you buy a PRO-UHD or 4K Enhanced (4Ke) – it means that you are only getting half of the resolution that a 4K UHD television or projector delivers. How is this possible? BenQ was one of the first brands to deliver a true 4K UHD projector using Texas Instruments new DLP chip that delivered true 4K UHD resolution with over 8 million pixels to mainstream home theater projectors. Other brands including Sony also market projector models with true 4K resolution, and while these models are more expensive, they all deliver over 8 million pixels to the screen.
What about projector models with "Pro-UHD" and "4K Enhancement" (4Ke) resolution? While they can receive a native 4K signal into the projector, they only display about half as many pixels - just over 4 million pixels on the screen at one time while a true UHD projector delivers over 8 million pixels at one time. Although the picture is an improvement over 1080p projectors you should be aware that a PRO-UHD projector image does not display a true 4K UHD image as defined by the Consumer Electronics Association.
FACT #2 – PRO-UHD is a marketing term – not an industry specification
If you’ve shopped for a 4K television, only 4K UHD is used in describing resolution. For projectors, the only products that use the PRO-UHD description are projector models from Epson. So what is PRO-UHD? It is just a registered trademark used to describe the resolution produced by Epson e-shifting technology.
Like automotive engines that use turbochargers to increase the horsepower out of an engine cylinder, projector manufacturers such as BenQ, Epson, JVC, and others use different chips and techniques to multiply the number of pixels on your screen. Epson's PRO-UHD projectors models using 3LCD technology can only produce 4+ million addressable pixels with a typical specification of “1920 x 1080 x 2” resolution. By contrast, every BenQ 4K UHD projector uses Texas Instruments DLP technology to achieve the required 3840 x 2160 resolution that produces images that Home Theater HIFI said creates "a stunning Ultra HD image that is simply unmatched by anything else I’ve seen."
FACT #3 – Retailers may market PRO-UHD as having true 4K UHD resolution
Although PRO-UHD projectors don’t meet the official 4K UHD standard, many retailers market them the same as 4K projectors that have twice the resolution. They may not make it clear that the resolution on a PRO-UHD model is lower than a true 4K UHD projector.
For example, one large North American retailer markets a PRO-UHD projector as “Epson - Home Cinema 4010 4K 3LCD Projector with High Dynamic Range – White”, but doesn’t display the actual pixel resolution of the projector. Another website misstates the resolution of the same model saying it has 4K UHD resolution. The Epson website even describes this model with PRO-UHD using the term "4K Enhancement (1)" that describes the resolution as 1920x1080x2, which is half of the number of pixels required for a true 4K UHD display. With descriptions like this, it is easy for customers to think they are getting the full 8 million pixels like they would if they purchase a BenQ 4K UHD projector – at a similar price point.
