The BenQ’s Cinema preset required little adjustment to achieve accurate results when calibrating for standard dynamic range (SDR) sources. Measured Delta Es (dE) for all color points were below 3—a level considered imperceptible—and saturation tracking was excellent. I ultimately decided to target a 2.2 gamma instead of a BT.1886 (2.4) gamma due to the projector’s limited contrast—while BT.1886 perceptually adjusts the gamma curve based on the measured black level, in this case it left the image looking washed out in the darker grayscale range.
The 5050UB was installed on a high shelf at the back of my room with its lens surface positioned 14 feet away from a 92-inch diagonal, 1.1 gain Stewart Filmscreen Cima screen. Similar to Epson’s 4010, the 5050UB features a 2.1x zoom lens and +/- 96 percent vertical and +/- 47 percent horizontal lens shift. These motorized adjustments on the projector make it easy to optimize image geometry and focus, and there’s also a pair of adjustable feet on its bottom surface to aid in shelf or table installations. Ten lens memory presets are provided for storing zoom and focus settings for installations requiring multiple display aspect ratios—when using a 2.35:1 aspect ratio “scope” screen, for example. Epson also says the that the level of accuracy provided by the 5050UB’s motorized adjustments makes it a good option for “Zero Edge” projection screens where there is minimal bezel area on the screen’s edges. ”
And the BenQ didn’t just excel in terms of its accuracy; the overall picture is equally appealing. Watching The Expanse on Amazon Prime in 4K SDR reveals images that are often spectacular. The projector might not be native 4K, but its XPR trickery results in perceived 4K images that don’t reveal any pixel structure, even when viewed up close.
An orbital assault exposes all the detail in the intricately rendered spaceships and station, while highlighting a DLP strength: smooth and judder-free motion. The sunlight reflecting off the ships’ hulls is suitably bright and the blacks of space are deep enough to leave the dynamic iris off. The projector’s adherence to REC.709 also ensures stable colours and excellent flesh tones.
The W2700’s new XPR DLP chipset brings another talent, in the form of improved black level performance. When our heroes escape from Hawkins Lab in Stranger Things (Netflix, Season 2, episode 8), through darkened corridors lit only by a flashlight, the projector manages to keep a watchable balance without crushing out the shadows. BenQ quotes a dynamic contrast of 30,000:1.
There are still limits to low-level fidelity from this well-priced beamer, though. As Chris Pratt hides behind a plinth from the raptor in the dinosaur museum (Jurassic World: Fallen Kingdom, 4K Blu-ray), there’s a void where shirt detail and shadow should co-exist.
