Al Griffin, Sound and Vision Magazine, Jan 2007, in his review stated that “The Sony's post-adjustment light output as measured from a 100-IRE window on a 93-inch-wide screen was 20.3 foot-lamberts, making it one of the brightest projectors I've tested. A degree of red fringing showed up on crosshatch test patterns, however, indicating slight misconvergence of the projector's SXRD imaging chips.”

In other reviews on this site Mr. Griffin states that the Optoma HD81 post adjustment light output measurement from a “100-IRE window on a 93-inch-wide screen was 15.6 foot-lamberts — nearly the same as for the more expensive Sim2 HT-3000.” Is this real that a professionally calibrated Pearl much brighter than these projectors?

Using the Projector Calculator on Projector Central, the JVC DLA-RS1 produces 16-fl on 93 inch wide screen and the Pearl hits 10-fl. Can anyone share additional information if getting the Sony Pearl professionally calibrated will produce a brighter image after calibration?

Mr. Griffin also states that professional calibration is almost a most of the Pearl because Sony states the s “slight misconvergence” of panels is within the manufacturing tolerance and Sony expects the owners to pay to correct any misconvergence problems.

No professional calibrator can adjust the convergence on a Sony. IT IS FIXED AT THE FACTORY. The panels are glued or soldered in place. Sony doesn't expect the customer to pay to have the convergence adjusted. It can't be ajusted.

HD-1 to my eyes

They are about the same.

Except when the iris kicks in on the Sony. Then the JVC stays high and the Sony drops.

As other have pointed out there is no calibration to correct any MC on the Pearl. I went through a total of four units due to MC issues before calling it a day.

The other thing to be aware of is the impact of the dynamic iris on brighness and black levels in mixed scenes.
