Better for AK800ST

  • Showroom

    5,000 lumens with BenQ's full golf feature set, for $900 less than the LK936ST and with BenQ's newer golf features; it gives up the LK936ST's lens shift.

  • Performance Seeker

    Brightness that holds up with the lights on, Golf Mode 2.0 and published low lag, with a zoom lens to fit the image from a range of mounting positions.

  • Family Setup

    Bright enough that the room does not need to be dark, with saved scene profiles for golf, movies and games.
