Hi all, I have been using an Optoma HD151X for a few months now and have notice sporadic 'sparkles' on the screen. They look like lively white pixels that are randomly dancing across the entire screen. Recently they have been getting more prominent, but there seems to be no rhyme or reason as to whether they'll happen the next time I turn everything on. Here's what I discovered today whilst swapping HDMI cables... Amazon TV -> Onkyo TX-SR875 -> Optoma HD151X :: SPARKLES Amazon TV -> Optoma HD151X :: No Sparkles Amazon TV -> Onkyo TX-SR875 -> Panasonic LCD :: SPARKLES Some people have said that the projector will be more sensitive to any problems compared to the LCD. Is it possible that I have a dodgy HDMI board on the Onkyo? Any help most appreciated, thanks.
