Benq TH671ST Viewsonic PX706HD
5 Reasons For
Quieter Noise Level
The Benq TH671ST is a 33dB projector. That's 3dB quieter than the Viewsonic PX706HD (36dB).

The noise level of the projector is the amount of noise that the projector makes (caused by the cooling fan inside the projector) when it is running.

A lower noise level means that the projector will be quieter when it is running. This means that you will be able to appreciate the quieter parts of films better without the background noise of the projector running. Most projectors have a noise level between 30 and 40Db, which rates them as 'very quiet' by Industial Noise Control - on par with low bird calls, or a quiet rural area. You can find more information here: http://www.industrialnoisecontrol.com/comparative-noise-examples.htm.

Mobile High-Definition Link (MHL)
The Benq TH671ST has a Mobile High-Definition Link (MHL), whereas the Viewsonic PX706HD does not.

MHL (Mobile High-Definition Link) is a protocol for streaming high-def video and images from a phone to the projector.

Better Kagoo Score
The Benq TH671ST has received a Kagoo Score of 87, however the Viewsonic PX706HD scored 85.
Cheaper by $51
The Benq TH671ST costs $50.99 less than the Viewsonic PX706HD.
Better Brand
Benq projectors have an average rating of 95%, whereas Viewsonic only has an average rating of 92%.
5 Reasons For
Higher Contrast Ratio
The Viewsonic PX706HD has a high (22000:1) contrast ratio, whereas the Benq TH671ST only has a medium contrast ratio.

The contrast ratio is the ratio between the brightness of the brightest white and the brightness of darkest black that the projector can produce.

A higher contrast ratio means that the projector can produce images with greater contrast so that they will appear more vivid.

Read more Read less | Edit
3D
The Viewsonic PX706HD supports 3D, but the Benq TH671ST does not support this feature.

3D compatible projectors are able to display 3D content. Most projectors will require you to wear special glasses in order to view the 3D effect.

A 3D projector allows you to view the huge range of 3D films and content that is now available.
