Overview

The BenQ TH681 is a 1080p DLP projector designed for home cinema and living room projection, with native 3D capability via DLP-Link technology. DLP (Digital Light Processing) projection is the technology of choice for sharp pixel edges and high sequential contrast — the single-chip DLP design eliminates the panel convergence and color bleed issues that can affect LCD projectors, delivering clean text and crisp motion on fast-moving content. The TH681 positions itself as a full-featured home theater projector with 3D support built into the hardware rather than added as an afterthought, making it compatible with 3D Blu-ray and 3D-enabled sources when paired with appropriate DLP-Link active glasses.

It's important to note that the TH681 is a legacy model, and the available product data for this listing is sparse — confirmed lumen output, contrast ratio, throw distance, and I/O count are not documented in this listing and should be sourced from BenQ's archived spec sheets before purchase. For buyers who find this unit at its available price point and can verify the physical condition and lamp hours, BenQ's TH-series build quality and color tuning make it a credible home cinema projector. Setup requires an external source device (Blu-ray player, streaming box, game console) and appropriate screen or projection surface — the TH681 is a display tool, not an integrated smart device.

Pros & Cons

👍 Pros

  • DLP projection technology delivers inherently sharp pixel structure and high contrast for 1080p content — DLP's single-chip design avoids the color convergence issues found in some LCD projectors at this price tier.
  • Native 3D support via DLP-Link is built into the projector hardware, not added via firmware — 3D-capable sources work without additional hardware adapters.
  • BenQ's TH-series reputation for color accuracy out of the box reduces the calibration burden for home cinema setups.
  • A 1-year commercial warranty provides documented coverage beyond what gray-market projectors at similar prices typically include.

👎 Cons

  • Available product data for the TH681 is extremely limited — I/O layout, lumen output, contrast ratio, and throw ratio are not confirmed in this listing, making pre-purchase room planning difficult without consulting external spec sheets.
  • As a legacy/discontinued model, lamp availability will diminish over time — sourcing replacement lamps for long-term ownership carries increasing risk.
  • DLP-Link 3D requires purchasing active glasses separately, adding cost and a charging/battery management requirement that passive 3D systems avoid.
  • No confirmed smart features, HDR support, or streaming integration — this is a display-only projector requiring an external source device for all content.

Frequently Asked Questions

Detailed I/O specifications are not provided in the available product data. BenQ TH-series 1080p projectors of this generation typically include HDMI, VGA, and composite inputs, but confirmed port count and layout for the TH681 specifically should be verified against the full spec sheet before purchase.
The TH681 supports DLP-Link 3D, which requires active 3D glasses. DLP-Link glasses are not typically included with the projector — they are purchased separately. Confirm 3D glasses compatibility with BenQ before purchasing third-party options.
Lamp life is not confirmed in available product data for this listing. BenQ home projectors of this class typically rate lamp life at 3,000–5,000 hours in standard mode. Replacement lamps for BenQ TH-series models are available from BenQ and third-party suppliers.
Throw distance specifications are not confirmed in the available product data. BenQ's TH-series projectors of this class typically require approximately 10–12 feet for a 100-inch image at standard throw ratio, but this should be confirmed against the manufacturer's full specification sheet for the TH681.
The TH681 is a legacy model (ASIN B00HR2PII8 suggests a circa-2013–2014 release). BenQ has moved to newer TH-series models. Lamp and accessory availability from third-party suppliers is typical for discontinued BenQ projectors, but official manufacturer support should be confirmed before purchase.
