Acer K11 Appearance
The Acer K11 has a sharp-looking, square, gloss black case. The lens is located slightly right of center and protrudes from the front of the projector, but has a cap to protect it when not in use. The lens is surrounded by a focus ring. To the left of the lens on the top edge is an IR receiving eye that can receive signals from both the front and top of the projector. There is a single height adjustable screw foot in the center for adjusting the height. On the left side of the front panel is an exhaust vent and fan.
On top of the projector, toward the rear, is a control panel with basic control functions. There are buttons for Power (with indicator light), Source selection, Menu and menu navigation (Up/Down/Left/Right buttons). The Menu button also acts as a Select button once a menu item has been highlighted.
On the right side (facing the front of the projector), is an air intake vent toward the rear along with a jack for the power supply connection. On the left side of the projector is an air intake vent and fan.
The rear panel is sparse, but manages to include an HDMI input. Starting at the top left, there is a 3.5 mm mini jack for either an audio connection or an AV connection. An RCA plug adapter is provided with the K11 to connect the projector composite video and stereo audio output jacks. Moving across the top from left to right, there is a VGA input for connection to a PC, followed by an HDMI input and a USB jack for displaying from a USB thumb drive. Along the bottom of the rear panel is a small built-in one watt speaker, an SD card slot and a Kensington lock.
Acer K11 Setup and Menus
Mini projectors like the K11 generally do not have any zoom capability (other than a digital zoom) and usually take more time to set up as the projector must to be positioned at both the correct height and distance from the screen. The K11 is no exception in this regard and only having a single front height adjustable foot does not make the task easier. Use of keystone adjustment is likely when setting up this projector, but the K11’s keystone correction works quite well and combined with the relatively small image displayed, does not cause noticeable distortion. Also, in the menu there is an “Installation” section that displays a grid that can be used with the keystone and other adjustments to properly align the displayed image.
Once it’s positioned, bringing up the menu, the user can select the desired display mode and make the usual adjustments (contrast, brightness, color and tint) to the picture. Compared to many projectors of this size, the K11 really excels at the number of adjustments available. There are six picture modes (plus a User mode) and five wall color settings to choose from. There is also a choice of different color temperatures and degamma settings. This is an impressive array of control from such a small projector.
Acer K11 Remote Control
The K11’s remote control is a very small, black remote with a one-piece button pad. Buttons are appropriately grouped and cover all the important functions without accessing them through the menu.
In addition to the usual Power, Menu and menu navigation buttons, there are also buttons for aspect ratio, source, video “hide” (which blanks the display), image re-sync and freeze. There are buttons for the digital zoom, accessing media on a USB drive or SD card (the right and left buttons allow for skipping through the media) and buttons to control the volume of the projector’s 1-watt built-in speaker.
The buttons are not backlit or even glow-in-the-dark, but that is pretty much the standard for multimedia projectors, much less one this small.
