Viewsonic PJ551D


Viewsonic's mid-level PJ551D is a portable projector that punches above its price point. It's not lightweight, but it performs capably for both office...

High native resolution, quiet

Low brightness for a new release model

The Viewsonic PJ551 is a model that targets the budget-conscious consumer, and it performs solidly. It may not have class-leading specifications, but for the price it's definitely a good choice.

Viewsonic PJD6210 DLP Projector [Review]


Smooth picture quality makes watching movies enjoyable

Limited connectors, not good for low ambient rooms, minor color bleeding

techtree reviews are amongst the most pathetic and useless reviews that you can read.....!!Even a 10th std student can write a better review

Excellent low cost projector


This projector displays high definition (HD} signal as well as 1280 x 800 PC screens. A bargain.

Bright projection; good control of keystoning; auto-search for video signal; light weight

No printed manual; some undocumented features (such as USB port)

Worthless product


Worst projector ever, I returned to the store for an exchange and the second projector had as bad a picture, and the fan broke the first day, and the projector wouldn't work after that.

Guranteed trip to the return counter

Poor picture, noisy fan, fan broke in 1 day

Good Product, great picture, simple to use!


I purchased this as a replacement for an older projector. It is much sharper, brighter, and has better color saturation than the one it replaced. Control range is somewhat limited but it works well.
