JVC DLA-RS4910 Inputs and Connections
These JVC projectors have a few goodies, but are also missing some standard inputs.
From the top left of the rear of the RS4910, you'll find two HDMI 1.4 inputs, and just to the right of them, is the RJ45 ethernet jack for networking. Slightly further right and down a bit is the rear IR sensor for the remote control.
Back of JVC's RS4910 Projector (and RS49, X500R)
Right below the two HDMI inputs, is a standard RS232 Serial port with the usual DB9 connector.
Moving down and back to the left, there's the DIN connector for the optional 3D RF emitter. To its right is a small jack for a 12 volt screen trigger.
That's it folks, although I note that missing are some low res inputs - composite video, and S-video, but we're definitely seeing more manufacturers no longer including those, especially on higher end projector models.
It would have been nice if one of the HDMI inputs was configured to support MHL, which would have allowed some internet smarts to be added, such as a Roku stick, or directly interfacing some android based phones and tablets!
We are starting to see HDMI with MHL in some home projectors, although mostly on the lower end of things. It's catching on rather quickly, as MHL has many benefits. My Roku stick, for example would have allowed me to do Netflix directly, as well as many other online services. Next year perhaps.
Note on MHL
Note: Of course, as one of our readers pointed out, after the RS4910 review was first posted, that a lot of what goes on with MHL, such as downloading movies and other content, has an audio component. The JVC projectors currently don't have either a speaker, or an audio output.
I'd still like to see MHL, but let's also ask for a digital audio out and a standard stereo audio out.
That would make movie watching off of my Roku stick work (assuming I have an audio system nearby. I expect everyone with a home theater projector has some sound system! Of course when I browse Roku's offferings there are some games, and news sources which are strictly visual, no audio components.
