Fellas, I've had my 81 for about 6 months now, and some of the inputs produce a darker screen image. My Xbox 360 image (connected to the 81 via component, HDMI to TV), and my DVD (connected to the 81 via HDMI 2, HDMI to TV) are darker. I'm losing tons of detail in the shadows, and the image is just darker. On HDMI 1 I have my cable box, and it does not suffer from the same problem.
Has anyone else experienced this? Will the firmware upgrade address this? I would have to ship my unit to Texas to get the upgrade, and the PCM over HDMI does not bother me enough to do it, but if the upgrade will fix the dark screen issue, then I'll have to do it.
