You are saying at normal viewing distances the Ruby @1080p just blew the 3 chipper @ 720p out of the water? no contest? What 3 chip DLP did you have in the same room? What was the screen size
No. Not "normal" viewing distance for 480p DVDs.
We are talking about a 1080p source here... Not upscaling to 1080p... Real 1080p. So why sit at 2X screen width? Those days are over. We were sitting in the first row at 0.8X-1X screen width. I prefer a total immersion experience and like to sit close to the screen, with the screen totally filling the field of view. IMHO, "normal" viewing distance for 1080p is 1X screen width (or less...
.
Sim2 C3X. 110" dia screen. Da-Lite Hi-Power.
With regular 720X480 DVDs and a Pio Elite 79AVi at 480i over HDMI to a Gennum VXP scaler (pre-production model), the C3x was giving us a really bright, punchy picture with some really good blacks. It was on par with the Ruby. After calibration, they were really near each other. Sitting at 2X screen width ("normal" viewing distance for regular SD DVDs...) was a tie. The C3X was brighter, but with some tweaking of the auto iris, the Ruby was also plenty bright.
But with a true 1080p source, and sitting at 1X screen width, the Ruby was clearly superior. Less noise, less artifacts, smoother picture. More details, no downscaling.
Both projectors were calibrated to D65 (with a dE of 4 or less from 10-100 IRE) and color corrected to Rec 709 primaries.
They are both outstanding projectors. The DLP was really bright and punchy. But with the 1080p source, the Ruby was simply better. 1080p is the future. 720p is the past.
I'm really anxious to try the upcoming 1080p DLP 3 chips. But for now, the Ruby is alone at the top of the performance/resolution/price ratio.
