JVC DLA-RS4910, DLA-RS49, DLA-X500R Projector Review

DLA-RS4910 PROJECTOR HARDWARE TOUR:  Overview and Lens, Control Panel, Inputs and Connections

DLA-RS4910 Projector - Hardware Overview

JVC’s DLA-RS4910 and its siblings are moderately large projectors.  They are about the same size as the competing Sony’s, a about a half size larger than the Epson 5030UB or the Panasonic PT-AE8000U projectors.  Of late, the only home theater projectors to grace our theater that are larger, have been the two true 4K resolution Sony’s.  Both are about a 1/2 size larger than the JVC, mostly taller.  Pick one up, and the JVC feels very serious, weighing in at almost 35 pounds, heavier than the others just mentioned.

The motorized 2:1 zoom lens is center mounted.  All functions are motorized – zoom, focus, and lens shift.  You’ll find exhaust vents on the outside portion of the front.   You’ll also find the front IR sensor for the remote control, just to the left of the lens if you are facing the projector.  Down below the JVC RS4910 has four screw thread adjustable feet – two up front, to in the back (of course)!  Also down below is one air intake.

Nothing on the sides, or the top (other than the logo on the top).  The rest of the action is in the back.

At the outer edges of the back are two more intake vents.  facing the back , the inputs and other connectors are on the left side of the projector’s back.  In the center of the rear of the JVC is the control panel, and the door for lamp access is to the right.

 

 

RS4910 Control Panel

No surprises here, JVC hasn’t changed the control panel for the third year in a row.  Located in the center of the rear of the projector it’s a fairly standard affair.

The power switch (On/Standby) is at the top.  Press once to power on, press twice to power down.  Next down is the Input – the source selector.  Right below that is the OK (aka Enter) button.  Most projectors put that button in the center of the arrow keys, but not JVC.

Well, those four navigation arrow keys are next, and they are set up in the popular diamond configuration.

That leaves only the Menu button on the bottom left, and the Back button (often called Escape), which moves you back up a level in the menus when pressed.

All the standard features, nothing extra.  Nicely spaced out.  Works!  By putting it on the back, it should be less noticeable than if on the projector’s top (if mounted), as that would be facing down.

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.

    I’m not sure why you would expect or want an MHL input on a device that does not handle audio. (There’s no way to get the audio out.) Any system using this projector would have a better place to connect an MHL device, like a receiver.

      Scott,

      Hi, you make a good point. I’ll amend my wish list and ask for MHL in, and a digital audio or other audio out as well.

      I’m going to add that to the review itself, thanks for noting that. -art

      • ScottJ97

        Sorry but I still don’t understand that wish. If there were an audio out, it would go to a receiver or such, which is also where an MHL device could be connected. Why would you ever want to connect an MHL device to this projector?

        • ProjectorReviews.com

          I’ll just ramble a bit: MHL without an audio solution, I fully agree, would not be an ideal solution. So, let’s try it again this way:

          I believe MHL with an audio solution would be an excellent decision. Perhaps bluetooth could be added as well.

          That would allow us to wirelessly pump audio to a stereo system, high quality HTIB, or even a top quality boom box. Not all of which would support HDMI switching (if you are thinking “let other devices handle audio and video issues”.) I’ve got a THX receiver that can’t even switch 3D because it’s old, so I bypass it and send my HDMI directly from sources to projector, and audio directly to the receiver. Why, because my receiver is dumb and is no longer compatible HDMI wise, with today’s usage.

          Since MHL is appearing on $400 pocket projectors, adding it should be pretty inexpensive. I’d certainly pay an extra $50 for a new projector to have it. Why close off your options. Bluetooth appears on $20 devices, so I’d happily toss in an extra $1. it wouldn’t cost JVC and others more than a few bucks to add

          MHL is a plus those who don’t want to pay the big cable, satellite bills could have other alternatives. And while I can’t see using MHL video quality compared to Blu-ray, I do watch DirecTV almost as much as I watch movies, so I, like anyone who’s not Blu-ray only, is already compromising quality – not getting a picture near as good as it could be, with even basic Blu-ray, let alone “4K” when it arrives.

          But a sad thing about projectors is they are pretty stupid compared to any premium LCDTV. Why. You spend $5K on a projector and get the smarts of a 2005 projector.

          I assume MHL has an upgradeable ability, and that makes me think of a Sony PS3. If that’s the case, 3 years from now your equipped MHL projector would likely upgrade to the latest capability just like a PS3 can do 3D and 4K photos, far beyond it’s original abilities, thanks to upgradability. If you can put that kind of future proofing into a $300 game machine… why’s a $5K projector built dumb?

          Unless you know where MHL is going, I’d suggest that thinking that it might have no use in the future would be foolish. But again, yes an audio solution would be needed, ideally wireless. -art

  • John Jordan

    Do reviewers like Art get paid for making an direct MHL input wishful thinking on a projector? LOL

    • ProjectorReviews.com

      Hi John, It might be wishful thinking, but no, I don’t get paid for such brilliance. Still, I’ve been very impressed with MHL this early in its development. Who knows, in a year, maybe we won’t need a cable box, but instead just an MHL plug-in device. The point is, it’s a wireless standard, that moves HDMI, sound, and command and control. Hmm, sounds much like HDMI itself, but it’s Wifi dependent as opposed to satellite boxes, blu-ray players etc. This isn’t even a discussion of quality.
      Personally I’m not even a big fan of satellite or cable, compared to Blu-ray disc, just as I prefer high quality records (especially half speed masters), over CDs, which I prefer over mp3′s and all the other junk quality super compressed, low sampling rate formats.

      But then, not everyone demands the finest in sources. Should someone feed a movie from Netflix via Roku, for max quality, no, but then, watching the same movie on DirecTV still leaves much to be desired, yet most of us have both.
      And who knows what MHL Gen 2, or 3 will bring to the party.

      Anyway I got on an MHL kick when playing with some of those low cost pocket projectors, as well as lower end BenQ’s and Epson’s.

      MHL isn’t a replacement solution, but if implemented well with an audio solution (which isn’t too tough), it could become very popular. Personally, I can’t wait for 4K Blu-ray. (or Ultra-HD, or whatever we’re calling it this month! -art

      PS. If you can figure out how I can get paid for such wishful thinking, let me know… Hey, I’ve been commenting in many reviews, for many years, that a 3rd HDMI input would be a real benefit for the non Receiver crowd, but so far, only Panasonic has added a third.

      • John Jordan

        Fair enough Art. It was only a crack nothing personal as i have read many of your reviews & the A-Z coverage in the reviews is really good. Also the PJ comparisons are good for anyone in the market.

        Yeah, hope the BDA get their act together regarding a disc format for 4k, then i am in. But until then well… IMO streaming & or video files just don’t have that little extra a Blu ray has, audio & PQ wise.

        Totally agree re: 3rd HDMI input for direct connection. The more the merrier as they say…

        Thanks Art.

      • ScottJ97

        That still doesn’t explain why an MHL input on this projector would make any sense (see my comment from 5/8/14 below).
