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. The main use of the projector will be for movies, but with some gaming. BenQ tell me that the W1800i runs at 16ms input lag, which is the same as the TK700STi so no issue there. Prices valid in stores (all including VAT) until close of business on 29th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) As noted earlier, the W1800 supports an optional extra Android TV dongle if you want it to go ‘smart’, and finally lamp life is claimed at an impressively long 15,000 hours. This will greatly reduce, though, if you watch a lot of HDR.
The sharpness remains strikingly high during camera pans and over moving objects, too. Judder without motion processing in play doesn’t look excessive – in fact, if anything it feels natural enough to simply add to the W1800’s key cinematic feel. Nor is there much trouble from the sort of fizzing and double edging around the edges of moving objects that affordable DLP projectors often struggle with.A further unwanted issue is that using the motion processing throws the syncing of the picture and the sound out when watching in 4K. It happens more than we’d expect, even when using the projector’s internal speakers, but can be resolved by switching the motion processing off. However, most home cinema amps will have an audio delay feature that can remedy the syncing. Lastly, if you’re using the included Android TV module, you’ll have to log into your Google account to access the Playstore and enjoy the different services available. BenQ W1800i: our impressions We just aren’t taken into the auditorium in The Prestige in the way the Optoma can. The audience is flat to the stage when we want to feel as if we’re sitting there watching Angier and Borden’s obsessive rivalry play out. It’s not easy to achieve, but we know it can be done at this price point. As respectable as the BenQ W2700 is, it doesn’t quite manage that. Ultra HD 4K resolution gives you four times more detail than Full HD with over 8 million pixels! It delivers a sharper, more life-like picture with richer and more natural colour. It also lets you sit closer to the screen – making it ideal for smaller rooms, too. With the BenQ W1800, you get a crystal-clear 120 inch image, with the projector positioned just 3 metres away. The only other note to consider is the noise of the projector fan, which is noticeable, but nothing beyond what we’d expect. If you’re sitting right next to the W2700, you’ll hear it, but otherwise it’s not a problem. Verdict
The W1800i is rated 2000 lumens, whereas the TK700STi is 3000 lumens. I believe that this is due to the RGB colour wheel on the W1800i, where the TK700STi has a RGBW and lets through more white light. The room I have will have some ambient light from the window (can shut the blinds) and table lamp. Seems like the TK700STi is better suited, but seems like there are varying opinions on whether 2000 lumens is plenty for this type of use. I was thinking about buying a 0.8 gain grey screen if that makes any difference. Once the projector is turned on, the welcome menu prompts you to choose the interface language, to specify the position of the projector and to choose whether or not to activate the automatic keystone correction. The image can then be adjusted within the limits of the screen by using the test pattern in the Installation menu. Once the ideal projection distance has been found, you simply have to adjust the zoom and the height of the feet to achieve the desired result. Thanks to the test pattern available in the BenQ W1800i projector’s installation menu, it is easy to adjust the image within the limits of the screen. Things start to go slightly awry for the BenQ W2700 when we start watching non-HDR films, which should still be a large portion of your viewing. You can still get a good balanced projection, but it takes a lot more work to get the best possible picture.The TK700STi achieves 97% of Rec709, where the W1800i achieves 100%. Does that 3% make noticeable difference, or can the 100% mean that it goes beyond this? Is it that important?
