LED Long Life
The LED light engine lasts up to 30,000 hours in ECO mode, 20,000 at full power.
Short Throw Projection
Large images in confined space.
MHL™ Connectivity
With the MHL connectivity, the projector is capable of performing the uncompressed HDMI digital signals and multi-channel audio from an MHL supported smartphone. The charging capability from projector to the battery of smartphone is also provided. Furthermore, with the Acer unique MHL wireless adapter attaching to the MHL™/HDMI™ port, the projector can display the content wirelessly from a PC, Tablet, Smartphone or Set-Top Box with Miracast or DLNA WiFi Display capability.
3D Ready
The Acer K138st uses active shutter 3D glasses with 3D DLP Link. This allows you to purchase 3D DLP Link Active Shutter Glasses from Acer or any other brand using this technology.
DTS Audio
DTS Sound™ is a sound enrichment suite that includes several post processing techniques to expand the sound image, enhance bass, improve definition and add natural surround effects
Bluetooth Audio
air one of those with the Acer K138ST, and you’ve got yourself a portable home theater! Better sound and portability isn’t all that Bluetooth has got going for it – since the Acer is a short throw, its placement will likely be in the middle of the room (in front of your seating area), and wired external speakers would have a bunch of dangly bits all around, hanging about in an unsightly manner. Bluetooth gives placement flexibility of the speaker, and without the tripping hazard.
Wireless options
There are two ways in which one can wirelessly project using the Acer K138ST: WirelessCAST and the WirelessHD Kit. Both are optional.
The WirelessCAST dongle allows for wireless projection from PCs and Macs. If you are running Windows XP, you can project video without audio, but Vista, and 7/8 all can project video with audio. It supports Mac OS X 10.8 or higher, iOS 7 and higher, Android 4.0+, and both iPad and Android tablets. The closest thing the WirelessCAST dongle relates to is Chromecast, though it is not a streaming stick in that you can’t stream Netflix or other services from the device.
The WirelessHD Kit is more for the “cord cutters” among us – those who do not desire cables strewn about everywhere. Since the K138ST is a short throw, it will likely sit in front of your seating area, making it an awkward position for your gaming systems and Blu-ray players. With the WirelessHD Kit, you can place those devices anywhere you want in the room with no regard for where the projector lives. Nice. It comes with a transmitter that connects to your image source via HDMI, and a receiver to plug into your HDMI port on the projector. The signal is wirelessly transmitted between the two devices. The WirelessHD Kit is capable of transmitting video and audio from a computer with an HDMI port.
