When it comes to image quality, both the BenQ TK850i and TK700STi use DLP technology with XPR pixel shifting to deliver sharp 4K images. However, the TK850i has a native 4K resolution, while the TK700STi uses a 1080p DLP chip and relies more heavily on pixel shifting. In practice, the TK850i will have a slight edge in sharpness and detail, especially on larger screens.
The TK850i also has the advantage in contrast, with a rated 3000:1 native contrast ratio compared to the TK700STi's 1000:1. This means the TK850i can display deeper blacks and a wider range between the darkest and brightest parts of the image. Both projectors support HDR10 and HLG high dynamic range formats, but the TK850i's higher contrast will make HDR content pop a bit more.
In terms of color performance, both projectors cover the standard Rec.709 color space used for most content. However, the TK850i has a slight edge in color accuracy out of the box, with a factory calibration that ensures realistic and lifelike colors. The TK700STi is no slouch, but its colors may require more tweaking to achieve the same level of accuracy.
Brightness is similar between the two projectors, with both rated at 3,000 ANSI lumens. This is plenty of brightness for a home theater setup in a light-controlled room, and even allows for some ambient light in the room. The TK700STi may have a slight edge in perceived brightness due to its more aggressive pixel shifting and color processing, but the difference is minimal.
For gaming, the BenQ TK700STi pulls ahead with its support for a 240Hz refresh rate at 1080p resolution. This means incredibly smooth motion in fast-paced games, with minimal blur or judder. The TK850i maxes out at 120Hz at 1080p, which is still great for gaming but not quite as buttery-smooth as the TK700STi.
Both projectors offer a low input lag of around 16ms at 60Hz 4K, which is fast enough for all but the most competitive gamers. At 1080p 120Hz, the input lag drops even lower, around 8ms. The TK700STi's 240Hz mode likely has even less lag, but it's overkill for all but the most demanding gamers.
In terms of installation flexibility, the two projectors are quite similar. Both offer a 1.2x manual zoom, vertical keystone correction, and a small amount of vertical lens shift. The TK700STi has a slightly shorter throw ratio, meaning it can project a larger image from a given distance. But both are relatively short-throw projectors that work well in smaller rooms.
The BenQ TK850i and TK700STi both use a lamp as their light source, with a rated lamp life of 4,000 hours in normal mode and up to 15,000 hours in SmartEco mode. Replacement lamps cost around $150-200, so factor that into your long-term cost considerations.
Both projectors offer a good selection of connectivity options, including three HDMI 2.0b ports (one with ARC), a USB-A port for powering streaming devices, an RS-232 port for integration with automation systems, and a 12V trigger for controlling motorized screens. The TK850i also has an optional wireless adapter for streaming, while the TK700STi includes an Android TV dongle out of the box.
The BenQ TK850i has a slight edge in audio with its dual 10W chamber speakers, compared to the TK700STi's single 5W speaker. However, for the best audio experience, you'll want to use external speakers or a soundbar with either projector.
Physically, the two projectors are very similar in size and design. The TK700STi is slightly lighter at 6.8 pounds vs the TK850i's 9.2 pounds, making it a bit more portable for those who want to take their projector on the go for gaming parties or outdoor movie nights.

The BenQ TK850i and TK700STi share a similar sleek, white design with rounded edges and a centrally-placed lens. The TK850i is slightly larger and heavier at 9.2 lbs and 12.3 x 4.3 x 8.9 inches, while the TK700STi is more compact at 6.8 lbs and 12.2 x 4.3 x 9.6 inches.
Both have manual zoom and focus dials, as well as a lens cover to protect against dust. The top panel features backlit buttons for power, menu navigation, and source selection. Ventilation grilles on the sides keep the internals cool.
On the back, you'll find an identical selection of ports, including 3 HDMI, USB, audio out, RS-232, and a 12V trigger. The build quality is excellent on both, with sturdy plastic housings and smooth lens controls.
A key difference is that the TK700STi includes an Android TV dongle for streaming apps, while it's an optional accessory for the TK850i. Both come with a high-quality backlit remote.

BenQ TK700STi User Reviews
Praises: "The TK700STi is an absolute beast for gaming. The input lag is virtually nonexistent and the 240Hz mode is so smooth, it's like playing on a high-end gaming monitor. The image is bright and punchy, even with some lights on. And the compact size is great for portability."
Drawbacks: "The native 1080p resolution is a bit of a letdown, and the contrast and colors aren't quite as good as some other projectors I've used. The built-in speaker is also pretty weak, so definitely plan on using external audio. But for pure gaming performance, this thing is hard to beat."
Overall, users are very impressed with the BenQ TK850i's 4K HDR image quality, ease of setup, and quiet operation. Some find it expensive, and there are occasional hiccups with the Android TV dongle, but most feel it's worth the price for the cinematic experience it provides.
The BenQ TK700STi receives high praise for its excellent gaming performance, especially the low input lag and 240Hz refresh rate. Users love the bright, vibrant image and portable design. The main complaints are the lower native resolution and weaker contrast compared to some competitors, as well as the lackluster built-in audio. But for dedicated gamers, the TK700STi is a top choice.
BenQ TK850i and TK700STi Alternatives
