Head-to-head

BenQ TK705STi vs BenQ TK710STi: 710STi adjusts to a fixed table, 705STi has lower 4K60 lag

The short answer

Choose TK705STi for Google TV and responsive 4K/60 gaming when its fixed lens matches the room. Choose TK710STi when a fixed table needs optical adjustment or a compatible PC will use 1080p high refresh. Lower listed lag at 60 Hz and a higher supported refresh rate solve different needs.

Before you choose

The reasoning and the trade-offs

Children gaming and adults watching sport need different checks

For ordinary 60 Hz console play, TK705STi publishes 11.7 ms less lag at 4K/60. TK710STi is the bounded choice for its documented 1080p/120 or /240 modes. Higher-refresh support on TK705STi remains unconfirmed because manufacturer scan ranges conflict. Live sport also depends on the source service and room lighting, so the gaming number alone cannot choose the family’s all-purpose projector.

What this is based on

BenQ TK705STi: 5 ms at 4K/60. The US page lists 23 to 60 Hz, while the manual lists a 23 to 120 Hz scan range and timing tables only up to 60 Hz. Higher-refresh support remains unconfirmed. BenQ TK710STi: 16.7 ms at 4K/60, 1080p up to 240 Hz. Difference 11.7 ms. No broadcast quality conclusion inferred.

Main trade-off

BenQ TK705STi

The fixed lens can conflict with a shared room. Confirm the exact higher-refresh input mode before selecting it for a high-refresh PC.

Main trade-off

BenQ TK710STi

The higher-refresh formats do not improve its published 4K/60 latency.

What matters in practice

The differences that matter

Children gaming and adults watching sport need different checks

For ordinary 60 Hz console play, TK705STi publishes 11.7 ms less lag at 4K/60. TK710STi is the bounded choice for its documented 1080p/120 or /240 modes. Higher-refresh support on TK705STi remains unconfirmed because manufacturer scan ranges conflict. Live sport also depends on the source service and room lighting, so the gaming number alone cannot choose the family’s all-purpose projector.

How we reached this conclusion

BenQ TK705STi: 5 ms at 4K/60. The US page lists 23 to 60 Hz, while the manual lists a 23 to 120 Hz scan range and timing tables only up to 60 Hz. Higher-refresh support remains unconfirmed. BenQ TK710STi: 16.7 ms at 4K/60, 1080p up to 240 Hz. Difference 11.7 ms. No broadcast quality conclusion inferred.

A shared playroom may have nowhere to move the table

At 120 inches, TK705STi’s fixed lens needs about seven feet. TK710STi covers about six to 7.2 feet. If the lens can only sit 6.5 feet away because the sofa and play space take the rest, only TK710STi fits the full picture optically.

How we reached this conclusion

BenQ TK705STi: 0.8 × 104.59 / 12 = 6.97 feet. BenQ TK710STi: 0.69 to 0.83 gives 6.01 to 7.23 feet. Image diagonal 120 inches at 16:9.

A cable-saving feature depends on the portable device

TK705STi can carry video and supply up to 30W through USB-C. That may reduce leads for a compatible low-power device, but does not establish full-power charging for a gaming laptop. In a room with children or pets crossing the floor, plan the complete cable route rather than assuming USB-C removes the power lead.

How we reached this conclusion

BenQ TK705STi: USB-C DisplayPort input and up to 30W power out. BenQ TK710STi: HDMI video inputs, no USB-C DisplayPort input listed. Exact device power and protocol must be checked.

No complete verified optical range is stored for this exact model.

BenQ TK710STi

Does not fit these inputs

For a 120-inch 16:9 picture, the calculated lens range is about 6.01 to 7.23 ft. Your input is 9.50 ft.

Distance is measured from the lens to the screen. The calculation uses a 16:9 image and the verified optical throw range for each exact model.

What you give up

Every choice has a cost
