BenQ TK710STi 3,200 Lumen 4K Short-Throw Projector with Android TV for Gaming

BenQ TK710STi – 4K gaming laser projector with short-throw lens and Android TV for gamers and film fans

The BenQ TK710STi combines a short throw distance, a laser light source and an integrated smart TV system in a compact housing. With 3,200 ANSI lumens, 4K UHD via pixel-shift technology and an input lag of 16.7 ms in standard game mode, the TK710STi is aimed at gamers and home cinema enthusiasts looking for a big picture even in a small space. Android TV enables direct streaming without an external stick.

Key benefits at a glance

• 3,200 ANSI lumens – enough brightness for semi-darkened rooms and large images of up to 300 inches
• 4K UHD (3,840 × 2,160) via pixel shift – 8.3 million pixels for richly detailed images
• Laser light source with a 20,000-hour lifetime – no lamp changes, full brightness instantly
• Short-throw lens (TR 0.69–0.83:1): a 100" image from a distance of just approx. 1.52 m
• Input lag of 16.7 ms in standard game mode – fast response times for PS5 and Xbox Series X
• Android TV with Wi-Fi: use popular streaming apps directly on the projector
• HDR10 & HLG: high dynamic range content in two widely used standards
• Dynamic contrast 600,000:1: deep black levels and bright highlights in the image
• 3-year manufacturer's warranty (36 months)

Applications

The TK710STi is designed for three scenarios, all of which it handles convincingly:

• Gaming in the living room: 16.7 ms input lag in standard game mode and down to 4.16 ms in optimised modes provide noticeable responsiveness in fast action and racing games. The short-throw lens keeps the projector out of the players' line of sight, even when the sofa is close to the wall.
• Home cinema and series nights: 3,200 lumens and 4K UHD bring film classics and streaming content to large screens in full resolution. HDR10 and HLG ensure that content from Blu-ray, Netflix or the ARD Mediathek retains its dynamic range.
• Football and sport: The combination of brightness, short throw and Android TV makes the TK710STi an uncomplicated companion for football nights, without having to move furniture across the room.

Picture quality

The TK710STi uses DLP technology with pixel shift: the 0.65" DMD chip shifts its pixels in rapid succession to display the full 4K resolution of 8.3 million pixels. The result is a richly detailed image with fine textures and clean edges. The dynamic contrast of 600,000:1 ensures dark black levels in night scenes and brilliant whites in bright passages.

HDR10 and HLG allow high dynamic range content to be displayed: HDR10 covers Ultra HD Blu-ray and most streaming platforms, while HLG is optimised for HD and UHD broadcasts from ARD and ZDF. The projector also supports 3D content via DLP Link. The integrated Eco sensor automatically adapts brightness to ambient light, sparing the light source.

Gaming performance

In standard game mode, the TK710STi achieves an input lag of 16.7 ms at 4K resolution. That puts it in the "very good" category for action, FPS and racing games. In optimised game modes, lag drops to as low as 4.16 ms. The projector supports refresh rates of up to 240 Hz.

Important for PS5 and Xbox gamers: the TK710STi offers 2× HDMI 2.0 with HDCP 2.2. HDMI 2.0 carries 4K signals up to 60 Hz; 4K at 120 Hz would require HDMI 2.1, which the TK710STi does not have. For competitive 4K gaming at 60 fps with low lag, it is nevertheless a powerful choice. HDMI-CEC also controls connected sources – one press on the projector's remote control is enough to operate a console or receiver.

Sound

The integrated 5 W speaker is suitable for casual gaming nights and spontaneous film screenings. For a true home cinema sound experience, we recommend an external soundbar or AV receiver. The 3.5 mm jack output connects the TK710STi to active sound equipment. HDMI-CEC also allows a connected receiver to be controlled via the projector's remote control.

Smart features & streaming

Android TV is integrated as the operating system. Numerous streaming apps are available via the Google Play Store, including YouTube, Disney+ and other services. Google Cast is also on board: content from Cast-enabled apps can be sent straight from your smartphone to the projector without an external stick. Wi-Fi provides access to home networks for 4K streaming. A stable 5 GHz Wi-Fi connection or a LAN cable (RJ-45) is recommended for smooth 4K streaming. LAN is available for network connection and firmware updates.

Note on Netflix: The availability of the Netflix app on Android TV devices depends on licensing. We recommend checking this before buying or using Netflix via an HDMI stick or games console.

Installation, connections & in the box

The short-throw lens with a throw ratio of 0.69–0.83:1 projects a 100" image from a distance of approx. 1.52 to 1.83 m. The 1.2× zoom range gives additional latitude when positioning.

The calculated throw distances are based on the manufacturer's throw ratio and are intended as guide values. With short-throw projectors, the exact distance to the wall is particularly critical – we recommend measuring the installation location precisely before buying.

The TK710STi supports table, ceiling and rear projection. Without lens shift, precise alignment of the projector with the screen is particularly important. Vertical and horizontal keystone correction (±30° each) and 4-corner correction allow digital adjustment of the image. For gaming: switch off keystone correction and position the projector physically correctly – digital correction increases input lag. Password protection and Direct Power On are provided as security and convenience features. A USB-A port (5 V / 1.5 A) powers external devices. RS-232 is available for control tasks.

In the box: Projector, remote control, power cable, batteries

Connections: 2× HDMI 2.0 (HDCP 2.2), 1× USB-A, 3.5 mm jack output, LAN (RJ-45), RS-232, Wi-Fi

Light source & running costs

The TK710STi's laser light source requires no lamp changes over its entire service life. It reaches full brightness immediately after switching on. At 31 dB in normal mode, the projector is noticeable but remains acceptable for living rooms with a normal seating distance. SmartEco automatically adjusts output in dark scenes, extending the life of the light source.

BenQ TK710STi – ideal for

• Gaming setups with little distance to the wall (PS5, Xbox Series X, Switch)
• Living-room home cinema with 4K streaming via integrated Android TV
• Football and sports nights with a big picture in a small space
• Beginners and advanced users who want to combine laser longevity with smart TV convenience

If you are looking for more flexibility in placement or are planning a larger image, models with optional lens shift or higher light output offer even more latitude. Get in touch – we will help you choose the right overall setup.

Have you thought of everything?

For the best results, we recommend the following additions to the TK710STi:

• Screen: A celexon motorised screen Professional Plus 220 × 124 cm (SKU 47123) suits the 100" class and can be operated conveniently by remote control. For bright rooms, an ALR screen (ambient light rejecting) is ideal – it absorbs stray light from above and maintains contrast even with ambient light.
• Ceiling mount: The celexon Universal MultiCel 1500 Expert (SKU 1090840) allows space-saving ceiling mounting and is height-adjustable.
• HDMI cable: For 4K with HDR, you need a certified HDMI 2.0 cable. From a length of approx. 7 m, we recommend an optical HDMI cable, as copper cables can reach their limits at this length.

Conclusion

The BenQ TK710STi is a thoughtfully equipped short-throw laser projector for the living room: 3,200 lumens, 4K UHD via pixel shift, 16.7 ms input lag in game mode and Android TV with Wi-Fi in a compact housing. The laser light source eliminates follow-up costs from lamp changes for around 18 years with moderate use. If you are looking for a big picture in a small space with low input lag and integrated smart TV, the TK710STi is a reliable choice.
