Have a completely dark room with a 133 inch screen that provides 1.3 gain. Mostly watch BlueRay and HD TV and video games. I find that the projector is dark. Don't know if its a calibration issue or if the bulb has slowly gotten dark over time or if it's just time for something new. Have been thinking about the HW55ES or VW95ES from Sony. The 95 costs more which makes me think it should be better, but it is listed at 1,000 lumens which is what my Marantz is listed at. I like the idea of 1,700 lumen from the HW55, but wonder if I will be making other image scarafices compared to my Marantz or the 95ES. Any thoughts are welcome.
