Pros and cons

According to our projector expert
  • This projector has a low input lag and high refresh rate to ensure smooth images, without much lag between the action on your controller and on the screen.
  • Thanks to the HDR support of this projector, you can see images with many color tones that give you colorful and high-contrast projections.
  • On the Android TV smart platform, you can easily stream movies and series from Disney+, YouTube, and Videoland, for example.
  • This projector doesn't have a short throw function, so you have to place it a bit further from the wall.
  • Netflix isn't a standard app on the smart platform, so you have to download it via the Aptoide app.

Description

With the BenQ TH685i, you can instantly project a documentary, game, or YouTube video on the wall. The TH685i is suitable for gaming enthusiasts, thanks to the 8ms input lag. As a result, the image doesn't lag behind the actions of your controller. In addition, the 120Hz refresh rate prevents screen tearing of moving images. So you can race past your opponent.

The projector has a Full HD resolution with HDR support, so the images have several color tones. That way, you can enjoy sharp and colorful images. For truly realistic images, purchase a 4K projector. The projector also has various game modes, so your image settings automatically jump to the ideal game mode. Done gaming? You can easily open a movie in one of the apps in the overview like Videoland or YouTube, thanks to the integrated smart function properties.

The TH6851 gives you placement flexibility, thanks to the zoom function, keystone correction, and lens shift. These functions ensure that you can tilt, enlarge, and reduce the image. You can also move it upwards, downwards, to the left, or to the right. Thanks to the light output of 3500 ANSI lumens, the projector also projects clearly during the day. So no more closing the curtains. The BenQ TH685i  has a throw ratio of 1.13 - 1.46:1, which means you can place the projector between 1.13 and 1.46m away from the screen for a 1m wide projection. For a 2m wide projection, you can double this distance to 2.26 - 2.92m. Make sure to first check where you want to place the projector and if there's space.
