Viewsonic PJD6531w

Noise (7.56)

We found the PJD6531w to be in the middle of the range when it comes to the noise it produces: it is not the quietest projector we’ve tested, or the noisiest. The noise is loudest at the left of the projector body (looking from the front) because of the large exhaust fans just inside the camera body that pull the air through the projector body, but we measured the overall average sound level at about 46.5 dB. Running the projector in the ECO mode reduces the noise level somewhat because the fans run slower: we measured the noise level here at about 44.4 dB.

Heat

The PJD6531w uses air to cool the hot internal components of the projector (such as the lamp), and this hot air is vented out of the right side of the projector body. We measured the difference between the air going in and coming out at a rather warm 110 degrees Fahrenheit (about 43 degrees Centigrade) in normal mode, or 104 in ECO mode. That is a big difference, and means that you definitely feel it if you are the one sitting next to the projector in a crowded conference room.

Power Consumption (7.05)

The PJD6531w uses quite a lot of power: we measured the power consumption in the brightest mode at about 300 watts. If you were to watch about 5 hours a day of TV, that would translate into an annual running cost of about $58.91 a year.

Changing the image mode of the projector didn’t make a lot of difference: we found that all of the modes used about the same amount of juice, including if the BrilliantColor feature was turned on or off. The only thing that reduced the power draw was engaging the ECO mode that reduces the brightness of the lamp. This reduced the power draw to about 244 watts, which would cost about $47.78 a year to run.

Mode	Average Watts	Cost per Year
Brightest	301	$58.91
Movie	300	$58.39
User (calibrated)	301	$58.76
Brightest (ECO)	244.5	$47.78

Power Consumption (modes)

Lamp Life

The lamp fits into a compartment at the front of the projector body. ViewSonic claims a 4000 or 5000 hour lifespan for this (in normal and ECO mode respectively) and a replacement bulb will cost about $240.
