Good Overall Performance
Clear But a Bit Loud
Most of the time the fan noise is noticeable but quite acceptable. Occasionally, however, the fan kicks into high gear and becomes distractingly loud, especially during entertainment applications, when the audience may actually want to hear what is being said. This fan problem, by the way, arose in both the default Bright and Standard power modes.
