BenQ TH685P: how it fits your system
The BenQ TH685P is a Full HD gaming projector with useful flexibility for both 1080p and compatible 4K sources. It displays a 1080p picture, while its 120 Hz Full HD mode and 1.3× optical zoom make it an interesting choice for responsive play in a planned room.
Why consider it?
- 8.3 ms at 1080p/120 Hz is specified for a compatible high-refresh source.
- It accepts a 4K/60 Hz input and downscales it to its Full HD display.
- A 1.3× zoom gives more placement adjustment than many entry-level 1.1× models.

Plan the setup
Check whether your console or PC and the specific game support 1080p/120 Hz. A source outputting 4K does not change this projector's displayed resolution, and it uses a different latency figure. Plan the screen and seating first, then select the best source mode.
Package, availability and India warranty
BenQ lists a remote, regional power cord and quick-start documentation. Confirm streaming devices, screen and mounting hardware separately.
NEEDS CONFIRMATION: current stock, supplied finish and quantity, included accessories and applicable India warranty. Ask AudioGuru to itemise these on the quotation. Screens, mounts, source devices, audio systems and installation are included only when expressly itemised.

Frequently asked questions
Is TH685P a 4K projector?
It accepts compatible 4K/60 Hz input but displays it at 1920 × 1080. It should be selected as a Full HD projector, with 4K input compatibility as an additional convenience.
How do I get the listed 8.3 ms response?
BenQ qualifies that input-lag figure at 1080p/120 Hz. Your source, game and projector settings must support that mode; the figure is not a guarantee for every input or processing setting.
How do I confirm price and delivery in India?
Contact AudioGuru with the exact model, finish, quantity and delivery PIN code. Confirm current availability, the GST-inclusive price or quotation, supplied accessories and applicable warranty before ordering.
Can I get advice in Pune before buying?
Yes. Our showroom is at Shop 9, Millenium Star, Dhole Patil Road, near Ruby Hall Clinic, Sangamvadi, Pune 411001. Contact us to discuss the equipment and confirm which products are available to view or demonstrate.
Our buying recommendation
TH685P is a useful shortlist when responsive Full HD play matters more than 4K display. Share your exact console or PC model so AudioGuru can help check the intended mode and installation.
