I have a 110 inch screen, about 14 feet from the projector
ahhh.. :-)You are use your original JVC glasses right? They will dont works with new model, try change polarisation with them over 90" and zou will see nice bright image.Because thats i sold my old glasses and bought new one. Original glasses will dont works.
I know that 3D is losing support and popularity but I would find it surprising if JVC suddenly made a new projector that is not compatible with their older 3D glasses. However, I have seen stranger things happen in the AV Industry.It's worth a shot to see if it works.
ST100 does retain polarization and the RS4500 is switched from the RS66, so he would get reduced brightness for 3D if using the old glasses.
You meant RS3000, eh ?
I was under the assumption the image was dim no matter type of content he was trying to watch. Is it just 3D that appears to be too dim?
