BenQ TK710STi Review (2026)

Quick Verdict: The BenQ TK710STi is BenQ’s answer for gamers and movie fans who want a true 4K image, a maintenance-free laser light source, and a short-throw lens that fills a 100″ screen from only a few feet away. With 3,200 lumens, a 4ms response time at 1080p/240Hz, HDR10/HLG, and built-in Android TV, it’s a genuinely feature-rich gaming-and-entertainment projector. At a street price typically in the $1,899–$2,199 range it is not cheap, but for buyers with limited room depth who want lag-free big-screen gaming and a 20,000-hour laser engine, it is one of the most complete short-throw options on the market.

Where the TK710STi Fits in BenQ’s Lineup

BenQ has long been the go-to brand for gaming projectors, and the TK710STi is the company’s modern flagship for the “I want a giant gaming screen in a normal-sized room” buyer. It succeeds the well-regarded but now-discontinued lamp-based short-throw gaming models by swapping in a laser light source and pushing the gaming credentials further than almost anything else in its price band. The “ST” denotes short throw, the “i” denotes the bundled Android TV smarts, and the combination targets a specific, growing audience: console and PC gamers who want a 100″+ screen, lag low enough to play competitively, and an install that fits an apartment or den rather than a dedicated theater. If you’ve been waiting for a true-4K, laser, low-lag short-throw projector, this is squarely aimed at you.

BenQ TK710STi Specifications at a Glance

How We Researched the BenQ TK710STi

This review draws on BenQ’s official specification sheet and the consistent conclusions of professional reviewers and retailers, framed as an honest editorial overview rather than a hands-on lab test. We did not benchmark this unit on calibrated equipment ourselves, and we accept no payment for placement. Performance figures are manufacturer specifications or measurements reported by independent outlets, clearly framed as such.

Picture Quality: True 4K with a Laser Punch

The TK710STi uses Texas Instruments’ 0.47″ DLP chip with XPR fast pixel-shifting to deliver a full 3,840 × 2,160 image on screen — this is the accepted industry definition of “true 4K” for single-chip DLP, and it produces a noticeably sharper, more detailed picture than 1080p-with-enhancement projectors like the Epson Home Cinema 2350. Text, fine textures, and game UI elements render crisply.

The laser light source is the other big story. At 3,200 ANSI lumens it is bright enough for rooms with moderate ambient light, and laser engines hold their brightness and color far more consistently over their life than lamps. BenQ quotes roughly 95% Rec.709 coverage, which is the standard HD/SDR color space — meaning accurate, well-saturated color for the vast majority of streaming and console content. Note that this is Rec.709 rather than a wide DCI-P3 figure, so for the very widest cinema color gamut, premium home-theater projectors will edge ahead; for mainstream gaming and movies, 95% Rec.709 looks excellent.

BenQ’s claimed contrast figure of up to 600,000:1 is a dynamic-with-laser-dimming number, as is standard across the industry; native DLP contrast is more modest. In practice the laser dimming helps dark scenes, but a dedicated dark-room or UST contrast specialist will still produce deeper blacks. For mixed-use rooms the image is bright, sharp, and lively.

Gaming Performance: The Headline Feature

This is where the TK710STi separates itself. It hits a 4ms response time at 1080p/240Hz — an extremely fast figure for a projector — and around 16ms input lag at 4K/60Hz. For competitive and fast-paced gaming on a giant screen, that responsiveness is a genuine differentiator; most home-theater projectors feel sluggish by comparison. The HDMI 2.0b inputs support 4K/60Hz and 1080p/120Hz, so console players (PS5, Xbox Series X) and PC gamers both have flexible high-frame-rate options.

BenQ also includes game-optimized picture modes that lift shadow detail so you can spot enemies in dark areas. Combined with the short-throw lens, you can run a 100″+ gaming screen in a modest room without the projector being far behind your seating — a practical win for apartments and smaller dens.

Short-Throw Placement Advantage

The 0.69–0.83:1 throw ratio means the TK710STi fills a 100″ screen from roughly 6.5 feet — far closer than the 10+ feet a standard-throw projector needs. That makes it ideal for rooms where you can’t place the projector at the back, and it reduces the chance of someone walking through the beam. It is not an ultra-short-throw (UST) unit that sits inches from the wall, but it is dramatically more placement-friendly than a long-throw model.

Picture Modes and Calibration

BenQ ships the TK710STi with a well-rounded set of picture modes, and the brand has a strong reputation for out-of-box color accuracy in its cinema and filmmaker-style presets. Expect a bright/vivid mode for daytime and sports, a more accurate cinema mode for movies in a dim room, and dedicated game modes that lift shadow detail and minimize lag. The roughly 95% Rec.709 coverage means SDR content — the bulk of streaming and gaming — renders with accurate, natural color without fuss. For HDR sources, BenQ’s HDR processing tone-maps the signal to the projector’s capabilities; as with all projectors, HDR here is about a more dynamic, colorful image rather than the searing highlights of a high-nit TV. Enthusiasts get color-management and gamma controls for fine-tuning, but most buyers will be happy on the presets.

HDR and Color in Practice

It’s worth being clear-eyed about HDR on the TK710STi. It supports HDR10 and HLG — not Dolby Vision — and its color spec is quoted in Rec.709 rather than a wide DCI-P3 number. For gaming and mainstream streaming, that’s entirely appropriate: Rec.709 is the standard color space for the vast majority of content, and the projector covers it well. Where it gives ground is to wide-color cinema specialists like the XGIMI Horizon Ultra (Dolby Vision, ~95.5% DCI-P3) and the Hisense PX3-Pro (triple-laser, near-full BT.2020). If your primary goal is reference-grade movie color rather than gaming, those are the projectors to weigh against it. For its intended gaming-and-entertainment role, the TK710STi’s image is bright, sharp, and lively.

Sound and Smart Features

The included Android TV dongle brings native streaming apps and Google Cast/AirPlay support, so it works out of the box without an external stick. The standout audio feature is HDMI eARC, which passes full-resolution Dolby Atmos and up to 7.1-channel audio through a single cable to a soundbar or AV receiver — a feature many projectors omit. The built-in speaker is serviceable for casual use, but eARC means serious home-theater audio is easy to add.

How the BenQ TK710STi Compares to Key Rivals

The takeaway: among standard/short-throw projectors, the TK710STi is the gaming specialist — nothing here matches its 4ms/240Hz responsiveness or its placement-friendly short throw. The XGIMI wins on cinema color and Dolby Vision; the Hisense wins on outright image and UST convenience at a much higher price; the Epson wins on value. For a gamer in a smaller room, the BenQ is the clear pick.

Value, Warranty, and Running Costs

At a street price typically between $1,899 and $2,199, the TK710STi is a premium purchase, and its value case rests on combining true 4K, a laser engine, and class-leading gaming specs in one short-throw body — a combination few rivals match. The laser light source is the running-cost win: rated around 20,000 hours with no lamp to replace, it eliminates the recurring expense that lamp projectors carry, and it holds brightness and color steady for the projector’s life. BenQ’s projector warranty terms are competitive for the category (commonly multi-year coverage on the unit with separate light-source terms). Factor in zero lamp replacements and instant-on convenience, and the higher upfront price looks more reasonable for a heavy-use gaming setup.

Strengths

• True 4K (3840 × 2160) via 0.47″ DLP with XPR pixel-shift — crisp detail
• Laser light source rated ~20,000 hours: no lamp replacement, stable brightness
• Outstanding gaming specs: 4ms @ 1080p/240Hz, ~16ms @ 4K/60Hz
• Short-throw lens fills 100″ from ~6.5 ft — great for smaller rooms
• 3,200 lumens handles moderate ambient light
• HDMI eARC for full Dolby Atmos passthrough; built-in Android TV

Limitations

• Premium price ($1,899–$2,199) versus 1080p-enhancement rivals
• Color spec is ~95% Rec.709, not a wide DCI-P3 figure for cinema purists
• Native contrast is modest; not a dark-room black-level champion
• Single-chip DLP can show rainbow artifacts to sensitive viewers
• No Dolby Vision (HDR10/HLG only)

Who Should Buy the BenQ TK710STi

Best for: Gamers who want true 4K, ultra-low lag, and a big screen in a room that can’t fit a long-throw projector.

Buy it if you: game competitively or play fast-paced titles on a 100″+ screen; want a maintenance-free laser engine; have limited room depth that suits a short throw; and want eARC for serious surround audio.

Skip it if you: are on a tighter budget (the Epson Home Cinema 2350 costs less); want Dolby Vision and the widest cinema color (consider the XGIMI Horizon Ultra); or want a UST projector that sits against the wall (consider the Hisense PX3-Pro).

Alternatives Worth Considering

Frequently Asked Questions

Is the BenQ TK710STi true 4K?

Yes, by the standard single-chip DLP definition. It uses a 0.47″ DLP chip with XPR fast pixel-shifting to put a full 3840 × 2160 image on screen, which looks sharper and more detailed than 1080p-with-enhancement projectors.

How good is it for gaming?

It’s one of the best gaming projectors available. It achieves a 4ms response time at 1080p/240Hz and roughly 16ms input lag at 4K/60Hz, which is exceptionally responsive for a projector. Console and PC gamers both benefit from its high-frame-rate support and shadow-boosting game modes.

What does the short-throw lens mean for my room?

With a 0.69–0.83:1 throw ratio, it fills a 100″ screen from about 6.5 feet — far closer than a standard projector. That makes it ideal for smaller rooms or setups where you can’t place the projector at the back of the room.

Does it support Dolby Atmos?

It passes Dolby Atmos through HDMI eARC to a compatible soundbar or AV receiver, sending full-resolution surround audio over a single cable. The built-in speaker is fine for casual use, but eARC makes adding a real audio system simple.

Does it need a separate streaming stick?

No. It includes a BenQ Android TV dongle with native streaming apps plus Google Cast and AirPlay, so streaming works out of the box.

Is the laser light source better than a lamp?

For most buyers, yes. The laser is rated around 20,000 hours, never needs a lamp replacement, and maintains brightness and color far more consistently over its life than a UHE lamp. It also reaches full brightness instantly at power-on.

Does the TK710STi support Dolby Vision?

No. It supports HDR10 and HLG, but not Dolby Vision. If Dolby Vision is a priority for movie watching, the XGIMI Horizon Ultra or Hisense PX3-Pro are the alternatives to consider. For gaming and mainstream streaming, HDR10/HLG is entirely sufficient.

What screen size and distance does it support?

With a 0.69–0.83:1 short throw, it fills a 100″ screen from about 6.5 feet and scales up and down from there. That short distance is the whole point of the model — it lets you run a big screen in a room where a long-throw projector simply wouldn’t fit.

Is it bright enough for a room with some light?

Yes. At 3,200 lumens it handles moderate ambient light well, especially with a quality screen. For the deepest contrast and best HDR you’ll still want to dim the lights, but it isn’t a darkness-only projector.

Final Verdict

The BenQ TK710STi is a polished, gaming-first 4K projector that also makes an excellent everyday entertainment machine. True 4K detail, a 20,000-hour laser engine, class-leading gaming responsiveness, a placement-friendly short throw, and eARC audio add up to a genuinely complete package. The trade-offs are the premium price, HDR10/HLG-only support (no Dolby Vision), and a color spec quoted in Rec.709 rather than wide DCI-P3. If you want lag-free big-screen gaming in a room that can’t fit a long-throw projector, it’s one of the most compelling options going. Weigh it against the alternatives above and current pricing to confirm the fit for your room.
