BenQ W1800 Projector Reviews:

W1800 review
What Hifi Review

The BenQ W1800’s pictures immediately struck us as genuinely cinematic as soon as we clapped eyes on them – and while deeper scrutiny uncovers a limitation or two, our first impressions hold well throughout our time with the W1800.

The single most striking strength of the W1800 is its colour performance. Whether you’re watching in one of the movie-friendly standard dynamic range picture presets or the Filmmaker Mode with HDR, colour tones across the board look beautifully natural, richly nuanced and remarkably well balanced for such an affordable projector.

W1800 review
Home Cinema Choice Review

Well, firstly it sports BenQ's CinematicColor technology, where RGBRGB colour wheels are dressed in 'rigorously tested' coatings to deliver more accurate colours, and, most strikingly of all, factory calibration reports (to Delta E errors below three) are supplied with each projector that leaves the factory.

The star of the show is the W1800's colour handling. Tones right across the board, with both HDR and SDR sources, look startlingly convincing, surprisingly nuanced, and clearly carefully tuned specifically for video playback.

The 4K Blu-ray of Kenneth Branagh's Death on the Nile adaptation presents a serious challenge from a colour perspective, with its slightly odd mix of naturalistic shots and highly stylised, CGI-heavy 'romanticised' visuals. The W1800 takes it all in its stride, portraying both the most low-lit skin tones and most vibrant Egyptian sunsets with equal conviction.

Expert Reviews

The first thing that strikes you with the W1800’s pictures is how smooth and natural they look. The Optoma UHD38 and BenQ TK700 deliver a brighter, slightly crisper image but, for cinematic visuals, the W1800 is in a different league. I tested it on a range of material using the Roku 4K Streaming Stick and 4K Blu-rays, from Marvel and Star Wars blockbusters such as Avengers: Endgame and The Last Jedi to The Marvellous Mrs Maisel, Reacher, Only Murders in the Building and Knives Out. The W1800 never faltered when it came to detail, colour, richness or depth. It’s always a good sign when I forget that I’m reviewing and settle in just to watch. With the BenQ W1800, this happened a lot.

Each projector is factory tested and adjusted for D65 color temperature, gamma, black level, white level, neutral grey, RGBCMY color tracking, hue, saturation, brightness and output based on ITU-R Rec. 709. All data is then compiled in an individual factory calibration report included with each W1800.

Delta E<3 performance means virtually no perceptible color difference to the human eye. (Delta E<3 performance enabled in D. Cinema modes.)
