AV Science Home Theater Equipment Demo Day, Saturday, February 8th, 2014.
We had 9 AVS forum members turn out for yesterday’s RS4910 / RS57 demo day at my house. I used the settings recommended by Zombie10K to do a quick out of the box optimization of these projectors. We checked convergence with the calibration disk brought by Joe-C on the 4910 – which looked quite good out of the box. We also checked for “ bright corners “ – that was not a problem with this projector either ( and I’ve been told by others this does not seem to be an issue with the new JVC’s in general ). A measurement of the 4910’s brightness ( I had the auto iris on auto 2, manual iris wide open ) gave a pretty uniform reading around 230 lux AEMC CA813 light meter. That’s 937.74 lumens with about 2 or 3 hours on the lamp. On my Stewart Cima Neve screen that’s about 23.5 foot lamberts !
Viewing distance was from 12’ 6” from a 59.5 x 106 x 122 diagonal Stewart Cima Neve screen and a
50.2 x 118 x 128.2 diagonal Stewart StudioTek 130 G3 screen. I like the lens memory feature a lot – it worked well in my theater on 2 screens !
We toggled eshift on and off to see the difference – I think that having eshift on really makes the picture look outstanding. I couldn’t see pixels with eshift on at all.
We watched a variety of Blu ray material – Oblivion, Pacific Rim, Samsarra, Tron Legacy, Avatar, Sin City, The Art of Flight. In my opinion motion, sharpness, contrast, the overall picture on the 4910 is just outstanding. Pacific Rim’s dark scenes in the battles off Hong Kong near the end certainly looked amazing on the 4910. HDTV looked very good too. A few of the attendees tested the 3D. Joe-C compared the 4910 with his RS45’s 3D – hopefully he will chime in regarding 3D of the current 4910 vs his older JVC. I’m not a 3D fan so I can’t comment myself.
All in all it was great having AVS forum members over to test these new JVC’s - hopefully some of them will chime in with their impressions of these projectors.
