BenQ TK700ST 3,000-Lumen 4K Short-Throw Projector with 16 ms Input Lag for Gaming and Home Theater

BenQ TK700ST – 4K Gaming Projector with Short-Throw Optics and 16 ms Input Lag

The BenQ TK700ST combines 4K UHD resolution with short-throw optics and an input lag of 16 ms – a combination that is equally suitable for gaming and movie nights. Even from a distance of around 2 meters, it produces a 100-inch image on the screen or wall. The 3,000 lumens ensure a bright image that impresses even in a living room with ambient light. DLP technology with XPR pixel shift delivers the full 4K resolution of 8.3 million pixels – with the advantages typical of DLP: precise motion sharpness, no convergence errors, and a dust-resistant lens.

Areas of use: What the BenQ TK700ST is suitable for

Gaming with PS5 and Xbox Series X

The TK700ST achieves an input lag of 16 ms – which corresponds to the "Very Good" rating for action titles, FPS, and racing games. The short-throw optics allow for a gaming setup directly in front of the wall or screen without having to plan for a long installation distance. The maximum refresh rate of 240 Hz makes the most of 1080p gaming content. For 4K with HDR10, both HDMI 2.0 inputs with HDCP 2.2 provide the necessary bandwidth and copy protection compatibility.

Home cinema with ambient light and movie nights

With 3,000 lumens and a 10,000:1 contrast, the TK700ST delivers an expressive image that holds its own even in a living room with ambient light. HDR10 and HLG ensure that content from streaming services and Ultra HD Blu-ray is reproduced with enhanced brightness and color dynamics. For movie nights in a well-darkened room, the 10,000:1 contrast unfolds its full effect – black levels are precisely rendered, while bright highlights remain clearly defined.

Football and sports events

3,000 lumens deliver a clearly visible image in a living room with ambient light – for game nights with friends without complete blackout. The integrated 5 W speaker bridges spontaneous evenings without an external sound system. The short-throw optics make flexible setup easier because the projector does not have to extend far into the room.

Image quality

The TK700ST relies on DLP technology with a 0.47-inch DMD chip. The 4K UHD resolution of 3,840 × 2,160 pixels is generated via XPR pixel-shift technology: The chip shifts its pixels in rapid succession to display the full resolution of 8.3 million pixels. This creates sharp images with fine details – whether for text, game graphics, or film footage. The brightness of 3,000 lumens and a contrast ratio of 10,000:1 ensure a balanced image with vivid depth.

HDR10 and HLG (Hybrid Log-Gamma) are the supported HDR standards. HDR10 is the base standard for Ultra HD Blu-ray and most streaming services. HLG is optimized for TV broadcasts and is backward compatible with SDR displays. Models with dynamic HDR standards such as Dolby Vision or HDR10+ can be found in our laser projectors – where enhanced HDR support with scene-based brightness control is standard.

Gaming performance

The BenQ TK700ST achieves an input lag of 16 ms – which is rated "Very Good" for most gaming genres, including fast action titles and sports games. The maximum refresh rate is 240 Hz, which enables smooth motion display for 1080p content. Those looking for tear-free gaming with a variable refresh rate in addition can find models with VRR and ALLM via HDMI 2.1 in our gaming projectors. For most casual and sofa gamers, the TK700ST remains a strong choice with 16 ms.

Sound

The TK700ST features an integrated 5 W mono speaker. This is sufficient for spontaneous gaming sessions and movie nights when no external sound system is at hand. For a full-fledged home cinema experience, a soundbar or AV receiver is recommended – the 3.5 mm jack outputs the audio signal. Those who want to pass through lossless audio formats such as Dolby TrueHD directly via HDMI will find this function in models with an eARC output.

Smart features & Streaming

The BenQ TK700ST does not have an integrated smart OS. External media players can be connected via the two HDMI inputs. There are two ways to stream content:

• Streaming apps (Netflix, Disney+, Prime Video): Connect an Apple TV, Amazon Fire TV, or Google TV Streamer via HDMI – full app support including DRM-protected content
• Wireless casting (AirPlay, Miracast, Google Cast): Plug in the EZCast Pro Dongle II via HDMI – enables screen mirroring and Multi-View without your own smart system

HDMI-CEC is available – compatible source devices can be controlled via the projector remote control without switching remotes.

Setup, projection & scope of delivery

The TK700ST is a short-throw projector with a throw ratio of 0.90 – 1.08:1. The housing depth is 24.6 cm. Add approx. 10 – 15 cm for cable connections on the back.

According to the manufacturer, this projector supports image sizes from around 60 inches upwards on large surfaces well over 100 inches.

The TK700ST can be placed on a table, mounted on the ceiling (upside down), or used for rear projection. No lens shift is available – for distortion-free projection, the projector should be aligned as parallel to the screen as possible. The digital keystone correction (±30° vertically, ±30° horizontally) allows for corrections in non-optimal setups, but reduces the effective resolution. For gaming: disable keystone correction and physically align the projector correctly to achieve the lowest input lag.

For ceiling mounting, a suitable projector ceiling mount is recommended. The projector hangs upside down – the automatic flip ensures an upright image. For rooms with an ALR screen and ambient light, an ALR screen noticeably improves the perception of contrast.

Scope of delivery: Remote control, power cable, batteries.

Connections:

• 2× HDMI 2.0 (HDCP 2.2) – for 4K/60Hz with HDR, compatible with PS5, Xbox Series X, Ultra HD Blu-ray players
• 1× USB-A (5V/1.5A) – for powering streaming sticks
• 1× 3.5 mm audio output jack – for external speakers or headphones
• RS-232 – for system control (power, input, brightness, volume, status)

Light source & operation

The TK700ST uses a UHP lamp. In Normal mode, a lifespan of 4,000 hours can be expected – for daily movie nights of three hours, this corresponds to around 3.5 years. Eco mode extends the lifespan to up to 15,000 hours and significantly reduces the operating noise level.

Models with an even longer lifespan and complete maintenance-free operation can be found in our range of laser projectors – with up to 30,000 hours and stable brightness throughout the entire service life.

The operating noise level is 34 dB in Normal mode – this is audible, but does not interfere with action movies and gaming sessions. In Eco mode, the volume drops to 28 dB – pleasantly quiet, only noticeable in very quiet passages. The power consumption is 310 W in Normal mode and 215 W in Eco mode.

Who the BenQ TK700ST is suitable for

• Gaming fans looking for a large 4K image with a PS5 or Xbox Series X without a long installation distance – 16 ms input lag and short throw in one device

• Movie nights and football events with friends, where ambient light in the room does not allow for complete blackout
• Users who do not yet need a smart OS and prefer an external streaming player

Upgrade recommended for

• Maintenance-free light source over 30,000 hours → Laser Projector with stable brightness throughout the entire lifespan
