Acer K135 LED Projector



Bright; Wi-Fi with DLNA support


Disappointing speaker



Acer’s K135 LED projector packs a punch, but is a little noisy for intimate rooms.

With a 110 x 140mm footprint – slightly smaller than a CD case – the Acer features a full-sized HDMI port along with USB, micro-SD and optional VGA, as well as 2GB of onboard storage. There’s also an optional $69 Wi-Fi adaptor, letting you stream to the projector using Acer’s eDisplay app or from any DLNA-enabled app.

Alternatively, iGadget owners might use a Lightning to Digital AV (HDMI) adaptor. You can also stream wireless from a Mac or PC via Acer’s eDisplay Management software.

At 430g this projector is designed to slip into a small travel bag, along with its tiny remote. It’s the only one of the bunch without a built-in battery, which might be a deal-breaker for some people but doesn’t seem an unreasonable compromise for the most powerful projector in this review.

The Acer offers 500 lumens brightness along with 16:10, 1280 x 800 native resolution, letting it throw the brightest picture of the bunch. It casts a 1m diagonal image sitting only 1.3m from the wall, although you can push back much further because it’s so bright. There’s a tripod thread on the bottom along with a foot to elevate the front, with the projector automatically adjusting the image to compensate for distortion

The two-watt mono speaker is rather tinny, but you can buy an extra cable to run audio-out via the Universal I/O port. Unfortunately the Acer features a whiny fan, not quite as loud as the BenQ JoyBee GP3 but perhaps more annoying.

You wouldn’t want to sit right next to it in a meeting, but the bigger and brighter picture means you can move further away from it and cast a decent image even if you can’t dim the lights.

Bottom line.

Even with the whiny fan, this Acer is the pick of the bunch because it offers the best balance between size, brightness and colour – assuming you’ve got access to a power socket.
