I had an RS40, RS50 and Acer 5360 on my 142" 16:9 2.8HP screen. the RS40 is brighter than the RS50, but as long as the projector is centered on the screen (about 6 inches above my eye level) the 3D output is quite pleasing overall (when the lamp is new)
It's dimmed 40% in about 300 hours but still fine on the 2.8HP. The Acer is putting out a measured 800 lumens in 3D mode and 1300 lumens with a rough D65 calibration which smokes the 40/50 with 3D mode lumens and this large screen.
The issue with the 5360 is that it's noticeable softer than the JVC's, especially on a screen this size. The 720P along with a cheap plastic lens doesn't help.
The Acer advantage is Brightness and zero ghosting from the DLP. The JVC advantage is much sharper image, better blacks and contrast, etc. The downside of the JVC is the quickly dimming lamp and ghosting is easily noticeable for me in some movies compared to the ghost free image of the Acer.
The ideal 3D setup for me would be the Sharp 17k for just 3D. 1080P and the ghost free images. Also the JVC needs a long warm-up time to watch 3D, at least 30 minutes before the ghosting is reduced. The Acer I can watch 3D the instant it's turned on.
plenty of pros / cons for each of these projectors.
