Model Overview

Behind the name TH681 is a 3D-DLP projector by Benq, whose main features include 3000 ANSI lumens, a contrast of 13000:1 and a HDTV 1920 x 1080 resolution. The runtime of the lamp in this model is estimated at 4000 hours before a replacement is necessary – mathematically sufficient for 5.5 years based on two hours of use per day.
A look at the light output reveals: The 3000 ANSI lumens are sufficient to illuminate an image width of up to 556 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 371 cm.
For media input, video signals up to 1080P as well as 3D are supported.
The projector was released in 2014 and is officially no longer distributed by Benq. However, it remains one of the frequently accessed models in our database.

A real buy tip!

A top device for the price. Incredibly vivid color reproduction, even on a plain white wall! Good zoom. Fan could be a little quieter, but not too annoying. A real buy tip!

Top 3D and FullHD projector

The Benq is my first Full HD and 3D projector and I am super satisfied! No RBE for me, I don‘t find it too loud either. 2D picture perfect, 3D picture brilliant. Easy to set up. Highly recommended.
