Vivitek D950HD Video Projector Review
The Vivitek D950HD is one of a few 1080p home theater projectors out now that cost less than a grand.
With the lamp set to Boost, the Vivitek D950HD only omitted a couple of decibels of fan noise, increasing the ambient noise from 38 dB to 41.5 dB. Our readings mark it as surprisingly meek for a projector. If you adjust the lamp to Standard, the noise output is almost unaffected, lowering the noise by 0.3 dB.
We measured the intake air temperature at 81º F, and the output at 133.5º F, which is really not bad for a home theater setup that can produce such bright pictures at 1080p. Changing the lamp from Boost to Standard will reduce the output temperature by about 25%.
The difference in power consumption between modes was veritably negligible. Bright is the most expensive mode. Changing the lamp setting from Boost to Standard will drop the yearly predicted cost. The costs listed in the table below are what we expect to see from projectors of this size and price point.
