Sony VPL-VW85 Projector - Performance 2

Posted on January 4, 2010 by Art Feierman

The Sony VPL-VW85 Brightness is better than the older VW70 it replaces.

Interestingly, last year, in measuring the VW70, Mike found that it wasn't measuring as bright when the dynamic iris was engaged. That wasn't a very good thing, since in best mode viewing you'll normally want the dynamic iris on, for better blacks.

This year, however, the VPL-VW85 doesn't seem to lose any lumens when Auto 1 or Auto 2 - the two dynamic iris choices are engaged.

Color Temp over IRE Range (Post calibration):
20 IRE 6503
30 IRE 6587
40 IRE 6561
50 IRE 6519
60 IRE 6480
70 IRE 6420
80 IRE 6520
90 IRE 6560
100 IRE 6413

Average gamma (using default Gamma 6) = 2.19

For those interested in using the iris in manual mode here are some brightness measurements:

Effect of Iris settings on lumen output (Cinema 1):
