HDMI Bandwidth. This projector has two HDMI ports. The first is HDMI 2.0 / HDCP 2.2 compliant with a bandwidth of 18 Gbps. The second is a standard HDMI port with bandwidth of 10.2 Gbps. This one is considered the best for sports watching and other Sport within the facility of your home but a stadium-like experience.

As mentioned above, both these models perform well and feature inspiring 4K HDR image quality so you can enjoy the best of the gaming performances within the ease of your home.Considering this, the lightbulb of TK800 features normally a 4000hrs of usage which is quite smart. Not only this, but you can also increase the longevity to whooping 8000hrs if you use your projector on SmartEco Mode. Our sample of the BenQ TK800 performs noticeably better than did our sample of the BenQ HT2550. The TK800 focuses sharply from edge to edge across the screen, brightness uniformity is up to 82% from 73% on the HT2550, and color balance in factory default calibrations is (oddly enough) a bit closer to neutral than was the HT2550 although it is still on the cool side. The other big feature is support for High Dynamic Range, specifically HDR10. Thanks to BenQ’s Auto HDR Colour Rendition technology, the TK800 can deliver HDR with greater brightness and contrast range than SDR. There are also image optimisation features designed to bring out all the detail in a 4K source. BenQ also state that the TK800 has auto HDR optimised colour rendition technology which matches the content to the native capabilities of the projector, to try and give a bright and more colourful image, over normal HD material. However the TK800 will only get close to the HD Rec.709 colour standard and nowhere near the current DCI-P3 gamut being used by Hollywood on UHD Blu-rays and the like within the Rec.2020 container. This means the projector is not wide colour gamut compatible, it will display UHD Blu-ray and other wide colour material in the Rec.709 HD standard. So again, it is worth cutting through some of the marketing to get to the actual performance parameters. Rec.709 done correctly is perfectly fine for this projector and the price point; it can look stunning when done correctly, we just feel BenQ need to be a little clearer on the specifications and less vague with the marketing.

Contrast is rated at a respectable 10,000:1, while a
new colour wheel with 'ultra-precise' red, green and blue coatings – and brightness-boosting white elements
– claims an impressive 92 per cent coverage of the REC.709 colour space. Throw range defines the picture quality from a certain distance and this is where both the models vary a little. The TK800 features about 1.2x zoom whereas the other one features 1.1x zoom. The video optimized presets are called "Cinema" on the TK800 and "Movie" on the PX747-4K. In these modes (with factory defaults) the PX747-4K delivers the more satisfying picture out of the box--it is higher in contrast and color saturation, has greater image depth (three dimensionality), and it has a warmer and closer to neutral color balance that makes flesh tones in particular look more natural. In HDR, the TK800M has great light output, too. On my 0.9-gain screen I was able to measure just over 50 foot-Lamberts (fL). To put this in context, a good light level in a dark room is around 15 fL, while you want that up around 30 with ambient light during the day. The extra brightness of the BenQ allows for some nice HDR highlights that really pop while using the projector in a dark room. It’s a product designed for a market that probably doesn’t really fit with your typical AVForums home cinema fan, but it does a decent enough job of what it sets out to do and at a reasonable price point. If we had tested the BenQ as solely a home cinema model for critical movie viewing it wouldn’t score well at all, given that niche set of image quality points it would need to hit, but this isn’t one of those projectors and doesn’t pretend to be.The Vivitek HK2288 is an example of a single-chip DLP projector that offers a similar design and an almost identical set of features. However it uses a larger imaging chip for a slightly better 4K experience, but also costs more, which gives you an idea of the competitiveness of the TK800. There’s a typical set of connections at the rear, that includes two HDMI inputs: the first is HDCP 2.2 compliant and should be used for any 4K/HDR sources, while the second is HDCP 1.4 and can be used for high definition. There’s also a PC/VGA input, an analogue audio in and out, a 12V trigger, an RS232 serial connector, and two USB ports. In the case of the latter, the first is for service updates, while the second can be used to power other devices.

Just like the above, this BenQ TK800M features amazing 4K projection Technology that works to deliver about 8.3 million pixels for an awe-inspiring and jaw-dropping 4K UHD performances. However, the HT2550 we reviewed was one of the first production units off the line. BenQ has done a firmware upgrade to that model since our review. Since our test unit of the HT2550 was returned after the review, we have not seen the latest HT2550 with the new firmware. Based on the improved performance of the TK800 we think the HT2550 is worth a second look. It is quite possible that there have been some QC tweaks in manufacturing that account for the improved image sharpness and brightness uniformity of the TK800 over the early edition of the HT2550. If that is the case the HT2550s being shipped today may look better than the one we tested. Also, you can opt for the User Mode that let you preferably adjust the EQ algorithms just as you prefer. BenQ TK800 vs BenQ Tk800M – Our Takeaway TK800’s lightweight design and sleek, compact profile accentuates beautiful aesthetics as well as intuitive functionality and eco-friendly design. A chic addition to your living room décor with easy setup, TK800 makes your home entertainment simple and comfortable for friends and family to enjoy parties, sports, movies.

For the finest gaming performances, you can also get the benefit of customisable Football and Sports modes that let you visualize immense 4K UHD images without missing a beat. Even without a dynamic iris, the contrast levels of the BenQ lead to some nice shadow detail while exploring in Shadow of the Tomb Raider. I’d still recommend keeping the curtains closed while the sun is out if you need to search for important items in dark corners, but for general play the TK800M performed admirably. Football Picture Mode preserves lifelike skin tones and lush green grass for stunning larger than life big-screen projection of every second of the match. And Football Sound Mode clarifies the announcer's every comment even as you're immersed in the cheering crowd in the open-air stadium atmosphere.

BenQ TK800 Projector is truly a dream projector that can display almost anything with perfection. The colours are vivid, bright, and sharp ensuring great on-screen quality even in well-lit ambient rooms.The TK800 doesn’t carry a native 3,840 x 2,160 set
of DLP ‘mirrors’, but can manipulate these mirrors fast enough to deliver two pixels from each mirror for every image frame. This, in conjunction with proprietary Texas Instruments processing, delivers a 4K effect that’s hard to distinguish from native 4K.
