Suport for High dynamic range (HDR)
High Dynamic Range is a method used in high dynamic range imaging and photography to display a range of brightness from the brightest whites to the darkest blacks, similar to the brightness experienced through the human eye in day-to-day life. HDR produces a wide variety of lights and darks so it appears much closer to real life.
This allows for a more entertaining product as it creates highly realistic images or videos for the viewer.
Currently there are five different types of High Dynamic Range: HDR10, HDR10+, HLG, Dolby Vision and Advanced HDR by Technicolour. At Pure Theatre, we supply different projectors with different varieties of HDR.
HDR10 is the most original and common HDR format that produces up to 1,000 nits of brightness with a 10-bit colour depth. It is an open standard used by numerous content creators and streaming services such as Netflix, Amazon and Blu-Ray, so doesn’t require licensing.
HDR10+ improves on HDR10 as it uses dynamic metadata and produces 4,000 nits of brightness whereas HDR10 will produce 1,000 nits. HDR10+ content will adjust brightness levels on a scene to scene basis simply by itself.
HLG (Hybrid Log Gamma) codes both HDR and SDR (Standard Dynamic Range) footage into one broadcasting signal, increasing efficiency for the broadcaster.
Hybrid - Encoding dual streams of SDR + HDR
Log - Logarithmic curve that transmits HDR’s wider brightness range
Gamma - Low Light image data encoded within the signal
Dolby Vision supports up to 10,000 nits of brightness with a 12-bit colour depth. Dolby Vision includes frame by frame metadata to correctly display to video or image and produce better quality videos or images. Dolby Vision is expensive as it need licensing, but it is much greater quality than HDR10.

Looking for the ultimate home cinema experience?
Enjoy the big screen experience at home with access to the latest 4K content with this affordable home cinema projector featuring sharp images, and an incredibly high contrast ratio, all with great connectivity and easy set up.
What is 4K UHD and eShift?
The term 4K refers to the resolution of an electronic display, such as a projection on a screen and has roughly 4000 pixels horizontally. Resolution is the number of pixels in that display and determines if the display is low quality or high quality. This depends on the number of pixels that make up the image or video, and the higher the number of pixels, the higher the resolution.
4K or UHD (Ultra High Definition) has a high resolution of 3840 x 2160 pixels giving sharp, hyperrealistic images and videos. Whereas, Full HD offers 1920 x 1080 pixels so has a lower resolution and doesn’t produce picture quality that is as detailed and sharp as 4K does.
If you are interested in a 4K product, ensure that the viewing distance is suitable. With 4K you can have a much larger screen as the resolution is higher or sit closer as there are a higher number of pixels. Also make sure you are viewing 4K content, as not all images and videos are taken in 4K - but with large companies like Netflix and Blu-Ray there is a range of 4K content available, and it is growing.
eShift or 4KE (4K Enhancement) is a system that initially starts with a Full HD 1080p chips containing 2.1 million pixels compared to 4K, which starts with an expensive chip containing 8.1 million pixels. When the eshift / 4KE system is activated and a 4K video input signal is detected, it is split into two 1080p images.
Each pixel is then rapidly shifted diagonally back and forth by a half-a-pixel width by the projector and projected onto the screen. As the shifting of the pixels is so fast, it produces a result approximating of a 4K resolution image to the viewer.This result overall totals a display of about 4.1 million pixels and although there are less pixels than 4K UHD, it appears as enhanced and does double the standard Full HD resolution. Below is an image to demonstrate this process of Pixel Shifting.
Size matters

Transform the everyday, whether you’re catching your favourite sports, watching a classic movie, streaming a box set or playing the latest game. You can capture everyone’s attention with an impressive 300” display and bring family and friends together to experience those memorable moments.
PRO-UHD
Enjoy amazing lifelike images exceeding Full HD resolution with our PRO-UHD projectors that accept 4K UHD content and upscale non-4K content.
Discover the features that add real value and make the PRO-UHD experience so special.
3LCD technology without the rainbow effect
Avoid the rainbow effect with Epson's projectors that use three individual LCD chips to simultaneously project red, green, and blue light.
In contrast, projectors with 1-chip DLP technology use a rotating wheel to project colours sequentially. Instead of a crisp edge, some viewers can experience the rainbow effect - a distracting and unnatural colour fringe.
Ultra-wide colour gamut
The ultra-wide colour gamut increases the range of lifelike colour, while the high contrast ratio delivers deep blacks for defined detail in the shadows.
Smoother fast-moving action
Even in the fastest action scenes frame interpolation and Detail Enhancement ensure motion pictures are sharp and smooth. Reducing motion blur in fast-moving scenes, frame interpolation technology inserts new frames between the original ones. As a result, blurring is suppressed and moving images look much smoother and sharper.
Flexible positioning and features for a true cinema experience at home
Looking for flexibility when it comes to installation? Ours is quick and simple thanks to a premium optical zoom ratio, and lens shift capabilities: up to ±96.3 percent on the vertical axis and up to ±47.1 percent on the horizontal axis. What’s more, the motorised zoom, focus and lens shift can store up to 10 different positions, letting you easily switch between different aspect ratios at the touch of a button. The high-quality optical zoom also makes it possible to use shorter cables, keeping any possible signal degradation to a minimum. In addition, this projector can be calibrated to professional ISF standards for greater control.
Enjoy up to seven years of entertainment1
With up to 5,000 hours lifetime on the lamps1, you could watch a movie every day for the next seven years without having to replace them. Epson projectors are known for their reliability, so you don’t have to worry about missing a minute of your favourite film, game or programme.
