This BenQ W1800i UHD-4K projector is not equipped with an LED lamp or laser, but with a conventional lamp that provides a brightness of 2000 lumens, allowing it to be used in a semi-dark or dark room. During the day or in a bright room, however, its brightness is a bit too low to achieve a sufficiently vivid and contrasted image. The lamp’s lifespan reaches 4000 hours in normal mode and 10,000 hours in eco mode. The lifespan of the BenQ W1800i’s lamp ranges from 4000 hours (normal mode) to 10,000 hours (eco mode) depending on the mode of use, which is equivalent to between 5 and 13 years at a rate of 2 hours of daily use. BenQ W1800i: zoom and keystone correction

The stunning 4K UHD (Ultra-HD) 3840x2160 resolution is four times the pixel count of 1080p FHD (full HD). With 8.3 million distinct pixels for each frame, the W1800i minimizes blur and displays crisp clear video. Additionally, the projector with the new generation 0.47” single-DMD DLP technology (chip) showcases a sleek modern design to complement your viewing space. Filmmaker Mode preserves motion cadence cinematic colour dynamic range and brightness that directors intended for the big screen. BenQ smart home projectors support the filmmakers’ desire for home viewers to relive majestic scenes and tender moments the way they were meant to be seen

But even with the W2700’s CinematicColor tech boost, it doesn’t match the Award-winning Optoma UHD40 for colour. Some parts of the spectrum lag behind – blues and reds are good, but the middle colours aren’t quite as vibrant. The brand's latest affordable 4K HDR beamer is out to show John Archer exactly what the director intended 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. Supercharged by HDR10 and HLG support with BenQ exclusive projector-optimized HDR the W1800i’s high dynamic range performance offers greater brightness contrast range and image optimization in a single step bringing out every detail in 4K video content for superior cinema enjoyment. keystone eliminates trapezoid effects when projecting from various room locations for ease and convenience.

Whether we are watching the 4K vintage world of The Prestige or the starker setting of Die Hard’s Nakatomi Plaza, the W2700 has the colours, the contrast and the brightness bang on, and that’s no mean feat. BenQ describes its approach as ‘true’ 4K, though, and crucially the independent Consumer Technology Association (CTA) in the US agrees.The chip is flashed at a rate of 240Hz (four times the normal amount) each time in a different position such that a full 4K, 8.3 million distinct pixels are displayed to the viewer per frame of footage. While many BenQ projectors sport CinematicColor technology, the W1800 adds another video-facing feature that we haven’t seen from a BenQ projector before: Filmmaker Mode. Developed by the Ultra HD Alliance, an industry body comprising a broad church of content creators and consumer electronics companies, the Filmmaker Mode picture preset is designed to deliver images that resemble as closely as a device can manage the video standards used by the creative industries when they master their content. Filmmaker mode is quite common on TVs now, but it’s still rare in the projector world. What’s more, potentially controversially, the W1800 actually defaults to the Filmmaker Mode whenever it receives an HDR image, and then won’t let you switch to any other preset. If you’re mad about movies, you’ll love Filmmaker Mode on this BenQ projector. Designed in collaboration with filmmakers and Hollywood studios, Filmmaker Mode lets you experience the cinematic vision, exactly as the director intended. Overriding the TV’s own motion and picture processing, Filmmaker Mode presents the correct aspect ratio, colour and frame rate – just as the filmmakers intended. The brightness limitation means the BenQ isn’t the best projector for use in brighter rooms. It is usable with some ambient light but it’s undoubtedly at its best in a darkened room. But there’s more to picture quality than brightness, as I’ll get to in a minute.

It’s the colours that swing it for the W1800, though. Not only did this projector slightly exceed Rec.709 in testing but colour accuracy is fantastic by projector standards, with an average Delta E of 2.89. Its only serious rival here is the Viewsonic X10-4K and that’s slightly more expensive. It is, though, hardly unusual for audio systems built into home cinema-focused projectors to be at best sound solutions of last resort, so the W1800 sounds in truth no worse than many of its rivals. Verdict There aren’t any specific gaming modes here, but the BenQ W1800 can run PC and console games at 1080p with a refresh rate of 120Hz or 240Hz. And while it’s no match for the UHD38 or TK700 on this ground, it’s still great for a spot of Destiny 2 or Elden Ring when you’ve finished watching films. You will need an external sound system, though. While the 5W internal speaker can get loud enough for casual viewing, the sound’s a little too flat and boxy for anything more. For optimal colour, the W1800 features BenQ’s CinematicColor technology. This tech 100% meets the Rec. 709 HDTV standard for colour accuracy, giving you realistic colour with true-to-life texture and depth. The RGBRGB colour wheel and high contrast deliver crisp images and help maximise the full potential of 4K resolution. It is worth noting that our first review sample had a fault that left a split in brightness down the middle of the picture when we adjusted the gamma settings. This doesn’t happen with the second unit, so we don’t expect it to be an issue.Once this module is connected to the projector, all that’s left to do is to connect to your Google account to take advantage of the online application catalog and to rent movies. You can also enjoy your subscription to Disney+, YouTube or Prime Video, as well as stream content wirelessly from a smartphone or tablet (iOS and Android).
