Si te refieres al calentamiento previo para un visionado en 3D libre de artefactos, te recomiendo que leas la review de cine4home sobre el funcionamiento de la tecnología D-ILA en el 3D
La mejora de luminosidad es irrelevante para la calidad de vision: los lumenes que tenia el x3 eran mas que de sobra para llenar una pantalla tipica 100"-110". Te quoteo un texto que imagino habras leido:
Me quedo mas con el ultimo parrafo que con el primero para el X3/X30 (no para los otros).JVC spec. for max. lumens are the same for the X3 and X30 and my discussions with JVC reps at CEDIA indicated that in 2D there would at most be a slight increase for the X30/RS45 as compared to X3/RS40. However 3D should be a little better when used with the new JVC 3D glasses as compared to the X3 with the old 3D glasses. The most significant brightness improvements are for the the X7-->X70 and the X9-->X90 (same for RS50-->RS55 and RS60-->RS65) where the light engine has been changed to use a fixed color correction filter with less light loss than last year's models. The X3 and RS40 did not have this filter and as a result they had higher light output (perhaps on the order of 20% or more). It is claimed that the X70/X90/RS55/RS65 should now be within 10% of the lumens output of the X3/X30/RS40/RS45.
I suspect any real visible difference in a comparison of the X3 or RS40 to a X30 or RS45 as for lumens output will be more related to bulb-to-bulb variations and slight variations in an individual projector's performance.
De todas maneras como bien dices habrá que esperar a la review de Cien4home (que son los únicos que prueban los proyectores con unidades de serie/"venta a la calle" y no de evaluación. Y digo prueban, porque los test los hacen a varios equipos).
