Epson Brightlink Interactive Projector Review – Performance: Brightness, Contrast, Audible Noise


Color ModeLumens

We’ve yet to perfect a way to accurately measure the lumens of an ultra short throw, as the angle at which the projector emits light is steep and therefore awkward to measure. With any other projector, it’s easy – the light comes from straight ahead. That said, the Epson BrightLink 710Ui measured over its 4,000 lumen claim. No surprises there – every Epson I’ve reviewed has done so thus far. Free lumens, I say!

In its brightest mode, Dynamic, the interactive projector measured 5,904 lumens. This is definitely one of the brighter projectors I’ve seen recently, and Dynamic reminds me of the lower brightness modes of the 6,500 lumen NEC business/education projector I reviewed last year. The 710 Ui’s Dynamic mode can cut through some gnarly ambient light. The next brightest mode is Presentation mode, which came in at 5,516 lumens. The projector’s best mode, Cinema mode, also measured over claim at 4,366 lumens. sRGB and Blackboard are the two least bright modes, with sRGB measuring in at 3,449 lumens and Blackboard at 2,843.


The BrightLink 710Ui has a high native contrast ratio of 2,500,000:1. Throughout the review, I’ve been continually comparing it to that Epson BrightLink 696Ui I reviewed about six months prior, noting the differences that might merit such a difference in price. This is one of them. Though the 696Ui had an excellent picture, it had a lower native contrast of 16,000:1, which is somewhat typical of business and education projectors. We’re not typically too interested in a projector’s native contrast specs, however, as it is truly about how the projector performs in terms of black levels. Business and education projectors don’t tend to have excellent black levels, as having the blackest blacks isn’t really top priority when viewing presentations and educational content.

After viewing this projector, it is evident to me that the BrightLink 710Ui has more depth to its picture than the other, with picture quality worthy of home entertainment. It looks really good! Blacks, though not true black (and not expected to be true black), were quite nice in Journey to Space. I included a photo below of a scene with a lot of black, for your reference. Educational films like this will look awesome on the Epson BrightLink 710Ui.

Audible Noise

Epson claims 38db as the BrightLink 710Ui’s rated fan noise when the projector is operating at full power. I would rate it less than that, as the fan didn’t really seem that loud, or at least, not bothersome. When taking my photos, I was standing about eight feet back and couldn’t hear it. The projector will be mounted above, so it is not in direct earshot like a projector mounted on a table top.

The BrightLink 710Ui has a claim of 27db in quiet mode, which is really quite excellent. Quiet modes will be your Eco modes, so the projector will lose a bit of brightness if you go that route. Should the room have a lot of uncontrollable ambient light, the little bit of fan noise you save will not be worth the dip in lumens.

That’s it for the Performance Page! The final page of our review is the Summary Page, where I’ll, of course, summarize, as well as tell you how this projector differs from the BrightLink 696Ui. I’ll also list some pros and cons so you can decide if this interactive projector suits your education needs!
