Before switching to FIOS, I was running my Comcast output to the projector via direct DVI since their set-top boxes had that connection. Upon upgrading to FIOS, their set-top boxes only have an HDMI output, along with component of course. So I simply bought an HDMI to DVI converter and hooked everything up. That's when the green snow (sparkles) started. Surprisingly enough, this does not occur when using component. Same cable length applies.
