This Dell projector is pretty well endowed. The input panel, is located on the side closest to the screen.
From left to right – furthest to the left, and far from the rest, is a small Kensington lock cable slot. Then comes venting, and then starting right about in the middle are the rest. There’s a mini-USB service port for doing firmware upgrades. Nice to know that the projector is designed to take firmware upgrades (without having to send it back to “the factory”).
Moving to the right is the RJ45 LAN connector for networking. Then comes three HDMI inputs, which, of course, handle data/video, audio and command and control. Two of them are the older HDMI 1.4, while one is HDMI 2 needed for a lot of 4K sources.
Another USB rounds out the top row. This USB is for PC free presentations (the Dell not only does PC free photos and video, but also can play Microsoft Office files, like Word, Excel and PowerPoint). Most interesting is that the USB port can alternately be used to plug in a Wireless dongle.
OK, second row: There’s an RS232 serial port for old school command and control (to turn on, change settings, etc., from a PC or other system set up to do control), followed by two Type A USBs.
Almost done. An SPDIF connector is there to provide Digital Audio output. Right next to it is an analog audio out, this time the connector is a stereo mini jack. Note audio out is variable, which is to say, you can control the volume from the remote or control panel, etc. Finally, the Power receptacle is located between the filters.
