When I wrote about my experience with 3D playback on my new JVC DLA-RS40 projector a couple weeks ago, I forgot to mention one major annoyance that has bothered me ever since: The projector’s 3D sync emitter doesn’t play well with the rest of my home theater gear.
In order to watch 3D on the RS40, you must purchase and install a separate 3D emitter. The emitter will automatically turn on and sync with JVC’s proprietary-branded 3D glasses. It works fine in that regard. The problem is that the sync transmission interferes with the IR remote control signals for some of the other components in my home theater.
I first noticed something wrong when I tried to watch ‘Resident Evil: Afterlife‘. The disc would load on its own all the way to the main menu, but I couldn’t use my Blu-ray player remote to select any of the menu options. In effect, this means that I couldn’t play the movie. Frustrated, the only thing I was able to do was eject the disc using the button on the player’s front panel (not the eject button on the remote). Once the disc was ejected, everything else seemed to work normally.
I assumed at first that this was a firmware compatibility issue between the disc and my OPPO BDP-93 Blu-ray player. However, attempts to play other 3D discs yielded the same result. They all froze up as soon as the projector kicked into 3D mode. I later attempted to watch 3D content on cable and likewise found my remote useless for commanding the cable box/DVR once 3D was activated.
It turns out that the JVC emitter is the culprit here. Covering up the emitter with a pillow blocks the signal and allows my Harmony universal remote to work again. I now have to do this any time I want to, for example, start movie playback from the main menu or pause for a break. In the emitter’s current position behind where I sit, this is already getting to be a real nuisance. I can’t imagine what owners who ceiling-mount their projectors will do.
I’m really surprised that JVC didn’t catch this in testing when the company designed the emitter. This doesn’t seem to be an isolated incident. Postings on other home theater forums confirm that this is a common issue across a wide variety of electronic devices. The JVC emitter blocks many IR remote frequencies.
