The BenQ TK700STi is a 4k HDR short-throw projector primarily meant for video games. Its short-throw lens projects a 100" image at a distance of 6.5 feet, 120" at a distance of 7.8 to 9.4 feet, and a very large 150" at a distance of 9.8 to 11.8 feet. The projector comes with 2D Keystone technology to eliminate trapezoid effects when it's installed off-center or at an angle, and also includes a picture rotation feature. Finally, it has two external and one internal HDMI 2.0b ports for 4k @ 60Hz or 1080p @ 240Hz gaming and an integrated 5W chambered speaker. It has Bluetooth support and comes with the Android TV 10 on its included QS01 dongle.
Our Verdict
The BenQ TK700STi is decent for watching movies. Its native contrast is satisfactory, and its brightness is decent, leading to a pleasant viewing experience when watched in a dark room, although its colors are a bit dull. Unfortunately, the projector's color accuracy before calibration is mediocre, and it doesn't improve much with calibration, so it's not the projector for color purists.
Bright enough to handle a few lights.
- Full suite of smart features with Wi-Fi and Bluetooth support.
Passes through DTS audio formats.
- Dull and inaccurate colors.
No Dolby Vision or HDR10+ support.
The BenQ TK700STi is a very good choice for gaming. It’s bright enough for a satisfactory gaming experience in a dark room, with equally decent contrast and color gamut, emphasizing its dark room chops. It's a very responsive unit with a ton of supported resolutions, and it has very low input lag, especially at 120Hz and 240Hz at 1080p. It doesn't officially support 1440p, which is a bummer for those using a Nintendo Switch 2, although it can be forced at 60Hz on the Xbox Series S. Finally, there's no Dolby Vision support for Xbox gamers.

Popular Projector Comparisons
BenQ TK700STi is a good gaming projector with 1080p @ 240Hz capabilities. Still, it's also no slouch for watching movies in a dark room with its satisfactory contrast and decent brightness, and it comes with an Android TV 10 dongle with many available apps. It's not the most portable projector due to its size and moderate weight, but its short throw capabilities make it easy to install in small rooms. Still, if you don't need the short throw or the Android TV dongle, consider the cheaper BenQ TK700, which is almost identical, except that it lacks these two features.
Check out our recommendations for the best 4k projectors and the best short-throw projectors. If you'd prefer to shop for a cheaper product, look up the best projectors under $1,000 instead.
The BenQ HT3550 and BenQ TK700STi are meant for different uses, as the HT3500 is primarily meant for home theater use, while the TK700STi is a gaming projector. Still, the TK700STi is no slouch for watching movies due to its satisfactory contrast and decent brightness, although the BenQ matches it for contrast. However, the HT3550 is significantly more colorful and much more accurate than the TK700STi post-calibration, making it the better choice for color aficionados.
The Optoma UHD35 and BenQ TK700STi are very similar projectors, with little to differentiate them. They're both gaming projectors, so they can project either 4k @ 60Hz or 1080p @ 240Hz. The Optoma offers marginally better image quality out-of-the-box due to its better accuracy and contrast, although the BenQ is the brighter projector. The biggest difference between the two products is the lack of wireless connectivity options and smart features on the Optoma. However, the BenQ comes with the QS01 smart streaming dongle with full wireless connectivity support.
The XGIMI HORIZON Ultra offers better image quality than the BenQ TK700STi, but the BenQ is a Short Throw projector, so you can place it closer to the wall or screen. The BenQ is also better for gamers as it can project both 4k @ 60Hz and 1080p @ 240Hz, while the XGIMI is limited to up to 4k @ 60Hz. Still, the XGIMI is brighter, has a wider color gamut, and is the more accurate of the two projectors.
The BenQ TK700STi and the BenQ X500i are both part of BenQ's 'Immersive Gaming' series, and share many similarities. Still, outside of the TK700STi's higher peak brightness, the X500i is the better product overall due to its much better contrast, wider color gamut, and superior pre-calibration accuracy. Plus, the X500i comes with the newer QS02 dongle, which has more features than the older QS01 dongle that comes with the TK700STi.
We've independently bought and tested over 60 projectors, and we've published all the detailed results for each so you can decide which one to buy. These have all been tested under the same standardized methodology, allowing you to compare them side by side. We still have all these projects in our lab so we can continually go back and compare them to ensure our reviews are still accurate. All our test methodology is also public on our website, so you can validate the results yourself.

This projector has decent brightness on a 100" screen and is bright enough for a satisfactory viewing experience in a dark room. Unfortunately, its colors are a bit dull. If you're looking for a similar gaming projector with better brightness, check out the BenQ X3100i.
The BenQ TK700STi has satisfactory contrast, leading to a pleasant viewing experience in a dark room, even if its blacks aren't very inky. If you're looking for a similar projector with better contrast, consider the BenQ X500i instead.
Before calibration, the BenQ TK700STi has mediocre color accuracy. While its white balance is good and its color temperature is excellent, albeit a bit warm, the projector's color accuracy is poor; all colors are significantly inaccurate, so this isn't the product for color purists.
The projector's image accuracy improves slightly after calibration, but it could be much better. Its color accuracy is better but still sub-par, and its white balance is about the same as before calibration. Its color temperature improved, but it was already excellent.
The BenQ TK700STi's color gamut is decent. It does a fantastic job with the Rec. 709 color space used with SDR content, but it can't adequately display the wider Rec. 2020 space.
This DLP projector uses a lamp as its light source, which can last from 4000 to about 15000 hours depending on the selected eco mode, after which you'll need to swap the lamp for a new one. It isn't a true 4k projector, as it uses pixel shifting to create a pseudo 4k image. This offers better quality than a pure 1080p projector but isn't as good as a native 4k unit.
Unlike laser/LED engines, which often have one or more narrow spikes in their SPDs, this unit's UHP lamp helps produce less saturated peak output in deep reds/blues than some laser models.
The BenQ TK700STi is a short-throw model with manual zoom/focus and manual keystone (no lens shift). Below are real-world throw distances for common 16:9 screen sizes:
- 80″ → ~5.23–6.28 ft
- 100″ → ~6.54–7.84 ft
- 120″ → ~7.84–9.41 ft
- 150″ → ~9.81–11.77 ft
- 200″ → ~13.07–15.69 ft
- 300″ (max) → ~19.61–23.53 ft
For the best sharpness and lowest artifacts, keep the lens centered on the screen and avoid digital keystone when possible.
The BenQ TK700STi projector has a somewhat compact design, but it isn't meant to be portable. You can carry it around, but at 7 pounds, it's a bit chunky. It also doesn't have an integrated battery, so you must ensure you have access to a power outlet to use it. The projector has auto keystone correction, but only on the vertical axis, so you must still center it horizontally. It doesn't have autofocus, so you must manually adjust that to get the clearest image possible.
The projector has two external HDMI ports, one of which is also the eARC port. It also has one internal HDMI port behind the rear BenQ cover, which is meant for use with the bundled BenQ QS01 Android streaming device, but you can also use it with other devices if you don't need the dongle. Google Cast is supported with the QS01 dongle, and the projector supports Bluetooth.
The BenQ TK700STi Accepts 4k @ 60Hz and 1080p up to 240 Hz. Full 4:4:4 chroma is supported at 1080p @ 60Hz. Unfortunately, the unit doesn’t officially support 1440p.
The BenQ TK700STi has very good latency, especially at 120Hz and 240Hz. Outside of Game mode, lag roughly doubles.
Even though there’s no advertised DTS, the projector passes through DTS:X (via DTS-HD MA) and DTS 5.1 without issue.
