“The W2700 has vents cut into both sides of its enclosure for cooling. The downside of this approach is that there’s greater potential for both light spillage and more fan noise. While there was some light-spillage from the unit, it certainly wasn’t objectionable.
All of the projector’s inputs are at the back of the projector and consist of two HDMI (HDCP 2.2) inputs, two USB A inputs (one of which is reserved for firmware updates), one USB Mini (for firmware updates), one audio out (3.5mm Mini Jack), one RS232 input and a single 12V trigger. The W2700 also has front and top-mounted IR receivers.”
