11/27/2023 0 Comments Acer k137![]() One nice little set up touch we much appreciated was the facility to tell the projector the colour of the wall you’re projecting on to, so that it can adjust its image settings to compensate.The Acer K137 projector fits in your palm for convenient use on the road. It doesn’t feature any optical zoom or image shifting either, so for most people getting an image on a screen or wall will just involve plonking it on a desk, adjusting the focus ring around the lens, connecting a source and maybe using the provided keystone adjustment to get the edges of the image perpendicular.ĭon’t forget that the built-in audio will negate the need to find an external audio source. And the K137 hits this target nicely.įor a start, like most LED-lit projectors, it fires up and shuts down instantly there’s no need to wait while it warms up and down. If it turns out to genuinely be as multipurpose as it sounds on paper, its £400 price point will start to look pretty reasonable.Ĭonvenience-based projectors like the K137 obviously need to be easy and quick to get up and running. Up to that point they should pump out between 560 and 700 ANSI lumens of brightness depending on which lamp mode you’re using – figures which are again strikingly high for an ultra-portable machine.Ĭolour should also stay reasonably true throughout the life of the projector thanks to Acer’s ColorSafe II system, which adjusts the picture settings to compensate for any colour decay over prolonged use.įrom these specs it’s no surprise to find Acer’s marketing for the K137 talking about it being a gaming and video projector despite its business-friendly Microsoft Office parsing. Once they die that’s basically the end of the projector’s life. Or to put it another way, the K137’s bulbs won’t ever need to be changed. Its DLP engine is illuminated by LEDs with a claimed lifespan of between 20,000 and 30,000 hours (depending on which lamp mode you use). Its native resolution of 1280×800 ticks both the HD Ready and widescreen (albeit 16:10 rather than the usual 16:9 aspect ratio) boxes, while its claimed contrast ratio of 10,000:1 is crazily high for an ultra-portable projector. The impressive first impressions continue with ithe K137’s picture specifications. The K137 is also DLNA-compliant, meaning that you can stream photos, music or video from Android/iOS/Windows smartphones, tablets and notebooks via an optional USB adapter. There are plenty of options for hooking up your sources, including an HDMI port with video, data and MHL (mobile phone) playback support type A USB and micro SD slots for direct playback of any Microsoft Office documents (ie Word, Excel and Powerpoint) as well as PDF files and even a Universal i/o port. With projectors like the K137 you just want to be able to take them out of a cupboard or pocket, plonk them down, hook up your source and immediately enjoy a full AV experience. But if you are you’ve clearly never tried using a small projector in either a business or casual home environment, where the last thing you want to have to do is try and find an external audio solution to provide the sonic accompaniment to your flashy Powerpoint presentation, corporate video, sports event or home movie. You might be wondering why sound matters on a device as focussed on visuals as a projector. But sound quality isn’t just about power it’s also about how that power is used, and in this respect the K137’s uniquely audio focussed design is very promising. We guess 6W doesn’t sound all that much on paper when you think that TVs often talk in terms of 20W and more these days. There’s even SRS Wow audio processing onboard, designed to deliver a wider soundstage and more dynamic, open performance from the speakers. Plus there’s a very good reason for the grilled part of the bodywork beyond mere aesthetic fanciness, namely that it’s the cover for a ‘360-degree’ audio system funnelling a 2 x 3W stereo speaker system out with much more room to breathe than you’d normally get from a small projector. It’s a very attractive design (it picked up a coveted iF product design award), and the build quality feels decent too – despite the fact that its 1.6in x 7.4in x 4.6in bodywork weighs just 1.1 pounds. Except, of course, for the little recessed projection lens on the right side of the front edge. ![]() With its rounded corners and distinctive combination of gloss white panels and light silver grille it looks more like a mini hovercraft than a projector. ![]() The K137 is a true one-off on the design front. The K137 is an ultra-small ‘travel’ projector that uses DLP technology and offers such surprisingly strong features as a 1280×800 native resolution, 3D playback, a built-in USB card reader, and most startlingly of all for a ‘pocket’ projector, a sound system that actually sounds decent rather than the sonic equivalent of two cans and a piece of string.
