Moving to the top of the projector we have the control panel. All the projectors functions are able to be controlled via the top of the projector. The control panel is backlit so finding the button you need is very easy if your in the dark as most presenters are when presenting. Chang brightness, color and even presentation sources with just a few taps of the buttonless panel. Overall the control panel is very intuitive and luckily you can control all the projectors functions should you happen to lose the remote control.
Antother really great feature of the projector is its sound system. The Infocus IN3916 and IN3914 have two, ten watt speakers on the left and right side of the projector. That is plenty of sound output for a small ballroom or large classroom.
Around to the back is where you will find the incredibly well equipped input panel. Just about every kind of input is there. Starting from the left, you have the LAN port for hooking up the projector to a network. Just below that you have the infrared receiver for the remote. Next to the LAN port you will find the USB input. The USB input serves two functions. It is the interface for the optional LitePort accessory that allows you to wirelessly connect the projector to a network or allow you to connect up to 32 different computers that can project their own presentations all at the control of the main presenter. You can even show 4 presenters computers at once. This feature however is specific to the IN3916 only. This port also allows you to hook up a USB drive and give your presentation via the USB drive (special software turns your Powerpoint slides into Jpeg images for viewing).
Next we have a trigger input for a screen and next to that the serial input should you want to control the projectors internal functions via RS-232. Next up is a mini USB port which allows you to connect your projector to your laptop to not only receive the laptops image, but to also allow for the LiteBoard interactive capabilities. Keep in mind that although you can receive the laptops image and control the laptop with the LiteBoard Wand, using this as your video input can cause the video card to degrade itself so that certain video card intensive characteristics become disabled. For instance the opaque toolbar in Windows 7 often turns a solid grey. A particular issue that happens when you install Windows 7 on laptops and desktops with old video cards. However, if you use the VGA input and the USB input for the LiteBoard Wand you will not have this problem, assuming your laptop or desktop has a good video card.
The IN3916 also has an input for HDMI and high definition content. Below that you will find two VGA inputs. The second input allows you to input component video via an optional Component to VGA cable. Moving to the right you have your standard composite input and two L/R audio inputs to take advantage of the 2, 10 watt speakers. There is also a 2.5mm input for a mic and a 2.5mm input for sound. A 2.5mm output is also built-in.
