LG PF85U versus BenQ W1070

Bill Livolsi, April 25, 2014
Review Contents


The BenQ W1070 is a projector with a great cinema image that also works well in the living room. It is not particularly fully-featured as home video projectors go, but its top-shelf image quality makes it a bargain.

The LG PF85U combines the features of a Smart TV with the longevity and convenience of an LED light source. However, with its relatively low light output and higher price, the value proposition is not as clear-cut as one might think.

In the end, you should buy the PF85U if you need a portable entertainment projector with a ton of features and can control ambient light. If you're looking for a dynamite entry-level home theater projector and want to save some money, you should stick with the W1070 until LED technology matures and LED-based projectors get brighter.

this LG Projector is not even close to W1070 BenQ Projector at all, base on quality,light output and the features, not sure why PC make this comparison. The only benefit of this LG Projector is the LED lamp feature life time, nothing else. which after 5 lamp burn out, I can buy another 1080P PJ at lower cost, why need LED ??

Any difference in audible noise? Does "less heat generation" mean less fan noise in real life?

Thanks so much for the comparison. The discussions of LED projectors is starting to get ridiculous. For some reason people are convinced that the LED models are just a clear cut replacement to the traditional lamp models, even though this is the only full 1080p model out there at a 'reasonable' price point. I think when these hit real lumen ratings of 700+ and can fill a 120" screen, and have basics such as zoom functionality, things may be much different, but not yet.

I'm also interested in what the fan noise was like on these models. That's always been a complaint of mine with the Casio models. The fans were so small that they made a higher pitched noise in the LED models compared to the lamp based models. Would love to hear how the fans sound in one projector vs. the other.

I have a few questions: 1. Did LG remove the VGA input that is common to billions of computers? 2. If they did then did LG quiet the highest light output fan noise since this would not be primarily a portable device for say laptops? 3. Is Wifi enabled by default? 4. Can wifi be totally defeated? 5. Can you suggest to LG that if they decide to introduce a 3d version that the offer a synch port that allows two projectors to double light output? Thanks for the comparison.

Something else nobody has mentioned is that LED projectors don't have mechanical spinning wheels as Bulb DLP projectors do because the LED's blink electronically and eliminate the need for the mechanical color wheel altogether. So what that means is an LED projector is mostly a solid state digital product, the LED's are diodes and so eliminating all mechanical parts should extend the life of the projector also, no moving parts to break.

A bulb projector might not last mechanically to make it 4 bulb changes.

Also by eliminating the spinning color wheel from the equation the chances of anyone seeing the dreaded rainbow effect is lessened even to the 5 % that are sensitive to it. I think this is important and something not mentioned here as a factor to consider.

Andonios - In our experience, the lack of a color wheel has very little effect on the appearance of RBE. LED-driven DLP projectors still use sequential color, so rainbows are still very much an issue.

I bought unic uc40 which is an LED projector. 1080p. and the only thing I was afraid is that, there is meagre ventillation. can this effect my projector? there is only 1 feet gap from projevtor fan.
