Supersize your sports nights, with the Android TV-equipped BenQ TK850i.

Google-certified Android TV for all-in entertainment
With Google-certified Android TV built-in, enjoying a huge range of sports and other entertainment is easier than ever. Connect via wi-fi to your broadband hub and get direct access to Google Play, for near limitless entertainment. With over 5000 of the latest Android apps, movies, TV shows, live sports, news, games, music and more, the TK850i is a constant source of entertainment. One-button app access to Amazon Prime increases the entertainment to the next level.

Premium lens
At the heart of any projector is the lens. Get this right and a beautifully crisp and precise image follows. The BenQ TK850i uses a high precision, 10-element, 8-group lens for enhanced light penetration and intense detail – bringing the picture to life.

HDR-PRO for ultimate detail
This exclusive technology takes HDR one step further. HDR-PRO consists of three BenQ technologies – HDR Brightness, Tone Mapping and Dynamic Iris. These three technologies enhance colour definition and contrast, making the image appear more real than ever.

Projector-optimised HDR10 and HLG
Compatible with next generation HDR10 and HLG, the TK850i is the ideal projector for getting the best out of your movies, games and TV broadcasts. HDR10 and HLG deliver greater brightness and contrast, for a truly life-like picture. Projector-optimised, these technologies work seamlessly to deliver a more natural picture on the big screen.

4K UHD Resolution
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.

Designed for ambient lighting
Featuring super-high brightness at 3000 ANSI Lumens, the TK850i is ideal for use in ‘normal’ living room light levels. This means you get vivid, dynamic colour, without having to draw curtains and blinds.

Dedicated sports mode
Enjoy enhanced video quality with realistic skin tones, balanced outdoor blues and greens, and warm woodgrains for indoor sports action. Sports Mode also boosts the thrill of victory, accentuating the announcer’s commentary and the roar of the crowd.

Motion Enhancer
Eliminate laggy images, jittery playback, and blurry shadows. Interpolated frames are generated and displayed between individual frames. The TK850i inserts 36 interpolated frames per minute for seamless, vivid 60-frames-per-second videos.

Get all your entertainment integrated, with the BenQ TK850i.

Rated 2 out of 5 by from Bright picture but too noisy Only had it a day and despite a bright picture, the fan noise was too loud! I could hear it over loud scenes! The picture was bright but not as sharp as my 6 year old optima! I’m returning it!!

Rated 5 out of 5 by from bang on! Most helpful on the phone during initial enquiry with no sense of wanting to rush me along. Product is exactly as described and delivered exactly as promised. Not the first time I've bought high end stuff off these guys and it won't be the last. Keep up the good work.

Rated 5 out of 5 by from Great picture Quality and easy to use I'm delighted with this Projector, I pull it out at the weekends or when ever there is a decent game of footy on. I also use the Projector up in my bedroom. I can't get BBC Iplayer and the ITV Hub to work on it yet, so I have taken this up with BenQ direct to see if this is possible.

Rated 5 out of 5 by from Excellent projector + amazing RS customer service Having an internal HDMI port with the QS01 dongle in the TK850i is a really nice combination for a 4K smart projector with excellent picture quality and a lot of I/O options. In ECO mode (which gives you the best colour accuracy in my opinion) the projector is very quiet. The auto-keystone feature is also very effective, and the AndroidTV feature only lacks Netflix from the common applications as I was able to sideload the BBC iPlayer even though it's somehow not offered via the Google PlayStore for this device. I was surprised to see how efficient the dongle is. After the initial setup, there is really no need to use the native remote as the dongle one can turn on/off the projector and control its volume. Regarding RicherSounds, I've been incredibly impressed in every aspect! They are the only retailer I found to offer a 6-year warranty on such items. Combined with very attractive prices, I will definitely get back to them when I need to purchase other AV items. I had heard good feedback about RicherSounds and my experience just confirms it.

Rated 5 out of 5 by from Superb picture quality This projector completely exceeded all my expectations. The picture quality is stunning, and the sound from it (which I wasn't expecting a great deal from) is actually far from shabby. I'm really glad a bought this as the cinemas are all shut and it's a great alternative.
